Are modern houses more fire resistant but have more higher levels of indoor pollution because of it?
Modern houses tend to be more fire resistant due to the use of building materials with better fire-retardant properties. However, these materials can sometimes contribute to higher levels of indoor pollution as they may release volatile organic compounds (VOCs) or other harmful substances over time. Proper ventilation and choosing low-emission materials can help mitigate indoor pollution in modern homes.
Yes, Arkansas does have pollution. In western Arkansas the trees and other vegetation grow very fast and hide a great deal of the environmental pollution. Many houses and other buildings are abandoned and never torn down or demolished which allows them to be overgrown by vegetation, but are an ugly sight until they are hidden. People continue to dump many things in the lovely rivers. Though the paper plants swear their emissions are controlled and harmless, anybody who lives near them can attest to the air pollution. Pig farms and chicken farms contribute to the pollution and have a difficult time controlling that pollution. I have noticed the smog is increasing in the Little Rock area, but it isn't as bad as in many US cities. Despite the pollution, Arkansas remains a beautiful state and a good place to live.
ISO 14001 is an international environmental document developed by the International Organization for Standardization (ISO) for the prevention of industrial pollution. The ISO represents about 150 countries.
Specifically ISO 14001:
Specifies the actual requirements for an environmental management system. It applies to those environmental aspects which the organization has control and over which it can be expected to have an influence.
It shows how an organization can:
- implement, maintain and improve an environmental management system
- audit its conformance with its own stated environmental policy
- demonstrate conformance internally and externally
- demonstrate compliance with environmental laws and regulations
- certify its environmental management system by an external third party auditors
- or make a self-determination of conformance
ISO 14001 also is available as course material for the certification of internal or external auditors.
ISO 14001 is part of the ISO 14000 family of standards which consist a total of 16 international standards. It is designed to to help company or organization in reducing any negative impact to the environment. While it does not absolutely dictate requirements in environmental performance, it serves organization as the framework in developing environmental management system.
No. Smog includes ozone and more compounds in the troposphere. Ozone is found in all layers of the atmosphere, where it protects all surface life based on DNA. When it is found in concentrations >0.05 ppm in the troposphere, it is considered a pollutant, a constituent of smog.
In my opinion, yes. There are alot of factories their that cause air pollution, plus all the people that find it okay to leave their trash wherever they please doesn't help.
What are the four gases that cause the greenhouse effect?
The four main global warming gases are:
- CO2 (carbon dioxide)
- CH4 (methane)
- O3 (ozone) and
- CFC (chlorofluorocarbons)
The four primary greenhouse gases are:
- H2O (water vapor)
- CO2 (carbon dioxide)
- CH4 (methane) and
- NO (nitrous oxide)
The difference is that a greenhouse gas traps heat, which helps regulate earth's temperature, but is not necessarily contributing to increasing temperatures. "Global warming" gases are those whose atmospheric increase are NOT primarily from natural sources. Since this question has been merged and combined with others, the difference seems appropriate to preserve her
Another view:Water vapor is the most important gas for both issues according to the IPCC's models. The current increase of CO2 is not enough to cause the driving of temperatures by itself and could not explain the warming alone. Water vapor is added, at increasing levels and with only a positive feedback in order to make this temperature increase a man made possibility. Without the increased water vapor, the issue would need to be from sources other than man induced CO2. Even the IPCC admits that the issues with water vapor are not well understood in their 2007 addition of the climate report but are very important for the overall warming. This increased water vapor also has a negative feedback that is ignored by most models and why the IPCC predictions are far higher than the temperature we are experiencing since 2007.
When will chernobyl be safe to return to?
I read that it wont be habitable for another 48,000 years! To be honest, no one actually knows!! It certainly won't be in our life time, although I think it is a lot less than 48,000 years. I've heard it's more around 400-900 years, until the radiation has gone back down to normal levels. That is the problem with Chernobyl and surrounding areas - the amount of radiation in the soil, water, everywhere is thousands of times over the normal levels.
there is a Fallout New Vegas so watch out for it. it sucks because it comes out next year in 2010
Why world environment day is celebrated on 5th June every year?
World Environment Day is celebrated on June 5th every year to raise awareness about environmental issues and encourage global action. It was established by the United Nations in 1972 and serves as a platform for promoting environmental conservation and sustainable practices worldwide. The date was chosen to coincide with the first day of the landmark United Nations Conference on the Human Environment, held in Stockholm in 1972.
Durning photosynthesis plants make food from carbon dioxide and what?
Plants make food from carbon dioxide and water during photosynthesis.
How much air is polluted each day by a car?
The amount of air polluted by a car varies based on factors like the age of the car, fuel type, and driving conditions. On average, a car emits about 4.6 metric tons of carbon dioxide annually, which equates to around 12.6 kilograms per day. This pollution contributes to air quality issues and climate change.
Why pollution in a watershed poses a potential threat to the river system that flows through it?
Pollution in a watershed can harm the river system by contaminating the water with chemicals and toxins. This can disrupt the balance of the ecosystem, harm aquatic life, and affect water quality for human use. It can also lead to eutrophication, algal blooms, and ultimately degrade the health of the river system.
What are some possible causes of water contamination?
This really depends upon what it is that is being contaminated, for example, contamination of drinking water, contamination of food, contamination of soil, etc. Improper disposal of sewage, sloppiness, dirtiness, lack of purification, industrial discharges, and vermin infestation are all among the possible sources of contamination of various things.
When excess fertilizer drains into a lake may occur harming fish populations?
Excess fertilizer in lakes can lead to eutrophication, where algae blooms deplete oxygen levels in the water, harming fish and other aquatic life. The high nutrient levels can also disrupt the balance of the ecosystem, leading to changes in the food chain and biodiversity. Implementing proper nutrient management strategies can help prevent these negative impacts on fish populations and the overall health of the lake.
Does carbon dioxide pollute water?
Carbon dioxide itself does not directly pollute water in the same way that other pollutants do. However, when carbon dioxide dissolves in water, it forms carbonic acid, which can lead to a decrease in the pH of the water (ocean acidification) and potentially harm aquatic life.
How many individual decon packets should be in your m295 kit?
A standard M295 kit typically contains four individual decontamination packets. Each packet is designed to be used for specific decontamination purposes such as skin, eyes, and equipment.
How much pollution does an average factory produce a day?
The amount of pollution produced by a factory can vary significantly depending on the type of factory, its size, location, and production processes. Generally, factories can emit pollutants such as greenhouse gases, particulate matter, sulfur dioxide, nitrogen oxides, and volatile organic compounds. To determine exact daily emissions, it is necessary to assess each factory individually based on its operational activities and environmental impact.
What does sources of ocean pollution include?
What are toxic wastes?
Toxic wastes are poisonous materials that are being dumped into the ocean. They harm many plants and animals in the ocean and have a huge impact on our health. Toxic waste is the most harmful form of pollution to sea life and humans. When toxic waste harms an organism, it can quickly be passed along the food chain and may eventually end up being our seafood. In the food chain, one toxic organism gets eaten by another, larger animal, which gets eaten by another animal, and can end up being our seafood. Toxic waste gets into seas and oceans by the leaking of landfills, dumps, mines, and farms. Farm chemicals and heavy metals from factories can have a very harmful effect on marine life and humans.
Many fishermen believe that the toxic chemicals in the ocean are killing much of the fish population. One of the most harmful chemicals in the ocean is lead. Lead can cause many health problems. It can damage the brain, kidneys, and reproductive system. Lead can also cause birth defects for people. It has been shown to cause low IQ scores, slow growth, and hearing problems for small children. House and car paint and manufacturing lead batteries, fishing lures, certain parts of bullets, some ceramic ware, water pipes, and fixtures all give off lead.
Many things found in the ocean may cause seafood to be dangerous to human health. The effect on humans from contaminated seafood may include birth defects and nervous system damage. Medical waste found in the ocean is being tested to see if swimmers have a chance of developing Hepatitis or AIDS. Other waste has been known to cause viral and bacterial diseases. This type of pollution can be stopped by watching what pollution we are letting into the ocean. People are trying to decrease the amount of waste in the oceans by recycling as much garbage as they can so there is a smaller amount of very harmful materials in the ocean.
Boating Pollution Prevention Tips
Whenever someone takes their boat onto the water for a ride, it is creating pollution that can be very harmful to the sea life. Boating pollution is the pollution that comes from the boats engine when it is running, and it pollutes the water, killing animals with the chemicals in the exhaust from the engine. The engine gives off excess gasoline, which pollutes the waters and ends up killing the animals. In order to make as little pollution as possible, what everyone can do to help is:
Only turn a boat engine on all the way when you need to.
Don't take your boat out into the water if you don't need to.
Be sure to store and transport gasoline in places where there isn't any direct sunlight because the gasoline will evaporate, and all of the gases that have been evaporated will pollute the air.
Every year, buy new or cleaner marine engines for your boats.
Garbage Dumping
Garbage dumping is the dumping of harmful materials into the ocean like human waste, ground-up garbage, water from bathing, and plastics. Most of the waste that has been dumped into the ocean in the early 1990s is still there today. One main cause of garbage dumping occurs when sewage pipes share their space with storm water drains. Rainfall causes the sewage pipes to overflow and the sewage waste mixes with the storm water drain, which flows into another water source such as a lake or river. After that, the garbage pollutes the ocean, kills plants and animals in the water (for example, the plastic rings that are around pop cans can get around an animal�s neck, causing it to suffocate), and makes the water dirty.
Waste water
Waste water is a disposal problem that needs to be taken care of. Waste Water is run-off from rainwater and usually ends up in rivers, lakes, and oceans. In order to reduce the amount of waste water, we need to make sure that the water that ends up in the ocean is clean. We can do this by watching how much pollution we put into the ocean. Whenever even a small amount of pollution gets into the ocean, it damages the environment. A lot of people don�t realize that this same pollution is going into the ocean every day and all the small amounts add up to a major problem. To decrease the threat to public health, safety, and the environment, we need to watch how much waste water we produce.
Other Sources of Pollution
Pollution causes a lot of plant and animal deaths in the ocean. In addition to boat pollution, other things that cause water pollution are agriculture (like pesticide run-off), land clearing, and people that pollute the environment without thinking about what harm it can do to animals and humans.
How are cars polluting the oceans?
Cars pollute the ocean a lot. Whenever a car gets driven, you may have noticed a lot of smoke that is coming out from the back of the car. This smoke doesn't go directly into the ocean. It ends up being in acid rain. Acid rain is pollution mixed with regular rain, and when acid rain gets into the ocean, it pollutes the waters and kills many fish over a period of time. Cars are big pollution source. If pollution from cars cannot be stopped or at least cut down, then pretty soon the amount of fish and other creatures in the ocean will decrease.
How is agriculture polluting the oceans?
Chemical pesticides, chemical substances used to kill harmful animals or insects, and fertilizers, chemical or natural substances put on the land to make crops grow better, are another source of pollution. When it rains, the pesticides and fertilizers get taken off of the plants and end up in our oceans, killing ocean plants and animals. They are used by animal and agricultural farms, plantations, industries (especially illegal ones), and believe it or not, our very own gardens. A way to decrease the amount of pesticides and fertilizers polluting rivers, lakes, and oceans is by watching the amount of pesticide spray that you put on the plants in your garden. You can also buy organic products, which are grown with only natural pesticides and fertilizers.
Households polluting the ocean
Chemical detergents, batteries, plastics, and sewage are all produced by homes and everyday human activity. Every day humans create and use these things, and every day, people are creating a risk to the plants and animals that live in the oceans and lakes by doing things like driving without carpooling and making sure batteries are not leaking. Some ways that you can protect the oceans are by recycling plastics, disposing of batteries properly, using rechargeable batteries instead of regular batteries, using less water, carpooling, and recycling.
The Ocean Zones
From the shiny, clear sunlight zone to the dark, murky midnight zone, lie facts about the three different zones of the ocean. Even though the very bottom zone is about ninety percent of the ocean, more than ninety percent of the ocean�s sea life lives in the top zone, which is why it is important that we do not pollute our oceans.
Sunlight Zone
The sunlight zone is also called the Euphotic Zone. This zone is the top zone, and it is also the smallest. The sunlight zone is only about 600 feet deep, but ninety percent of the ocean�s sea life lives in the sunlight zone. This zone is home to a wide variety of marine life because plants can grow here. Plants can grow here because sunlight can get to the plants in this zone, so the plants can do photosynthesis and grow. Also, the water temperature is warmer than any other zone in the ocean. The sunlight can reach this zone and warm the ocean water, so it is warm enough for fish and other sea life. Sharks, tunas, mackerels, jellyfish, sea turtles, sea lions, seals, and stingrays are a few of the animals that live in the sunlight zone.
Oil Pollution
Pollution is major problem in the sunlight zone. The main kind of pollution that occurs in this zone is oil pollution. The two main causes of oil pollution in the ocean are big ships leaking oil or ships carrying oil crashing into things in the ocean.
Global Warming
Global warming is affecting many different parts of the ocean as well. It is causing the water to rise, and when it rises, it covers things such as low land islands with plants, animals, and even some people�s homes on them. This can hurt animals in the different layers of the ocean.
One other way ocean layers are affected by global warming is that warm water, caused by global warming, is hurting and even killing algae which is what some fish in the sunlight zone eat. These fish would die because all of their food would be gone. When the fish die, it is a break in our food chain, which would lead to a big problem for all of the animals that rely on the algae-eating fish for their food.
Twilight Zone
The twilight zone is also called the Disphotic Zone. In depth, the twilight zone is about 2,400 feet, making it the second largest zone. As the water becomes deeper, the water pressure becomes higher. Almost no sunlight can reach this zone. Therefore, very few plants can grow here. The only animals that can live here are those that can adapt to very little sunlight, really cold temperatures, and very high pressure. The few animals that can live in the twilight zone are lantern fish, rat-talk fish, hatchet fish, viper fish, mid-water jellyfish, octopus, and squid.
Many animals that live in the twilight zone have bodies that protect them from predators. The viper fish and the ratchet fish have fangs so they can easily protect themselves and help them eat their prey. Other fish are so thin that when a predator looks at them, they do not even see them! Some fish are colored red and black to blend in with their surroundings.
Some squid and fish can use their bodies to make light with special organs in their bodies called photophores. These photophores give off a greenish colored light, which helps them see. Most fish in this zone don�t chase their prey. They wait for their pray to swim by. Then they snatch their prey and eat it.
Toxic Pollution
Some of the pollution that causes problems for the amazing creatures of the twilight zone are metals and toxic chemicals. These toxic chemicals settle in the sea, and eventually some of the fish eat these chemicals. Other fish eat these fish that ate the chemicals, and these fish, too, will eventually die because they are putting toxic pollution into their bodies.
Midnight Zone
The midnight zone is also called the Aphhotic Zone. Ninety percent of the ocean is the midnight zone. This zone happens to be the bottom zone, so it is completely dark. Very few creatures in the ocean live in the midnight zone because the water pressure is extreme and it is near freezing down that far.
Some of the very few creatures that live down in this zone are angler fish, tripod fish, sea cucumbers, snipe eels, opossum shrimp, black swallower's, and the vampire squids.
Because of the lack of plants at this depth, all of the creatures in this zone are predators. They survive by consuming bacteria which grows from the mineral-rich materials and hydrogen sulfide that are given off by underwater cracks in the earth�s crust. Since there is no light down in this zone, some fish do not even have eyes.
Anoxic Water
One problem caused by pollution that occurs in the midnight zone is called anoxic water. This means that there is no or hardily any dissolved oxygen in the water. When there is no dissolved oxygen, fish and other creatures can't breathe, and they will quickly die from a lack of oxygen. Some of the creatures that live at this depth might die or migrate to other parts of the ocean. If they do migrate, there is a possibility that there could become a problem in the food chain.
It is very important that we address the issues that affect the ocean. Ninety percent of sea creatures live in the sunlight zone, which is the zone that is most affected by global warming and oil pollution. We must stop these problems because if we don't, we will hurt and maybe even kill our sea life.
- I would also like to add for the person that asked the question that I have been watching WHAT IS being done to try to curb pollution (if it's ever possible) and enjoyed a program on several different countries such as Australia and South Sea Islands, are now sinking some old ships so it gives the coral a chance to grow once again. Coral and many other sea life forms are close to becoming extinct in the next few more years unless humans get their heads together and start finding ways to replace what they take.
- Oil spills. Pollution problems started when the factories were next to houses and the pollution was all over the place.

Will one day the earth be destroyed by pollution?
Strangely enough the world has already gotten through severe pollution related changes.
Originally the earth had a reducing atmosphere (one without oxygen) as photosynthesis became more popular among life forms the content of oxygen rose destroying the environment for anaerobic organisms. Oxygen was in this case a pollutant.
In today's world ithe levels of pollution will never reach a stage where all life is destroyed - something will be left that can take advantage of the new environmental conditions. We may not survive, life will. So the world will not be destroyed - just us.
How is electricity made in a way that doesn't harm the environment?
All human activity impacts the environment. The line between impacts and harms is difficult to establish. In the case of electricity generation there are several ways of generating electricity each with its own set of impacts. These are: * Thermal fired generating plants: Systems in which some material coal, gas, biomass is burned can cause thermal pollution of water ways, use water taking it away from other users, have emissions problems (soot, carbon dioxide, nitrogen oxides, sulfur oxides) and have waste disposal issues. Fuel sourcing may entail environmental disruption, processing, transportation and handling issues. The common problem of building the plant and infrastructure exists. * Natural Origin Thermal Power Systems: Steam is recovered from geothermal features (geysers etc.) and used to produce electricity. This is limited to specific geological formations and locations. The common problem of building the plant and infrastructure exists. * Nuclear Thermal Power Systems:Systems in which some radioactive (fissionable) material is used to heat water to steam can cause thermal pollution of water ways, use water taking it away from other users. Fuel sourcing may entail environmental disruption, processing, transportation and handling issues. Waste handling is a significant issue. The common problem of building the plant and infrastructure exists. * Hydroelectric Power Plants: Electricity is created by water pressure or water falling over a cliff. The dams and reservoirs built for these systems disrupt ecosystems over large ares including fish migration as well as being a source of methane (a greenhouse gas) due to anaerobic decomposition. In the case of waterfalls the system diverts or disrupts water flows and fish migration. The common problem of building the plant and infrastructure exists. * Solar Power Systems: Electricity is generated by banks of solar cells. Large installations may require hundreds of acres. The sourcing of materials required for construction of solar panels requires mining and manufacturing issues involving toxic materials. The common problem of building the plant and infrastructure exists. * Wave Power Systems: Electricity is generated by banks of small units powered by the oscillation of waves. Large installations may require hundreds of acres. There is fear that fish, sea mammals and navigation may be impacted by the installations. The common problem of building the plant and infrastructure exists. * Wind Power Systems:Electricity is generated by rows of wind turbines. Large installations may require hundreds of acres. The sourcing of materials required for construction of wind turbines requires mining and manufacturing issues involving toxic materials. There is fear that birds and bats may be impacted by the installations. The common problem of building the plant and infrastructure exists. * Tidal Power Systems: Electricity is created by water pressure or water collected by dikes in tidal estuaries. The dams and reservoirs built for these systems disrupt ecosystems over large areas including fish migration, as well as the diversion or disruption of water flows. The common problem of building the plant and infrastructure exists. * Fuel Cells: Oxidants and fuel are brought together in a catalytic cell to generate electricity. If the fuel is hydrogen the generation of that material requires other polluting sources. If the fuel is methane or other hydrocarbon the cell produces carbon dioxide as well as being produced in some other polluting process. The common problem of building the plant and infrastructure exists. All in all the best source for electricity is probably Natural Origin Thermal Power generation.
Describe at least two ways in which upwelled water might differ from the water around it?
Upwelled water may differ from surrounding water in terms of temperature, nutrient content, and oxygen levels. As water moves to the surface through upwelling, it can bring nutrients from deeper layers, leading to higher nutrient concentrations in upwelled water. This can result in increased biological productivity in upwelling regions. Additionally, upwelled water tends to be colder and more oxygen-rich compared to the surface water, which can have significant effects on marine ecosystems.
How does SUV harm the environment?
it uses too much gas. ----- The largest complaint against SUVs is that they are more vehicle than the owners actually need. The large SUVs that draw the greatest ire are built on truck chassis, and have large V6 or V8 engines and 4-wheel-drive systems. All of these make them heavy and give them poor fuel economy. These systems are intended to give the SUVs large carrying & towing capacities, and make them capable of handling bad roads or offroad terrain. However the large percentage of people who purchase them rarely or never carry large loads, nor drive off road. So they could easily use a smaller more fuel-efficient vehicle like a sedan or minivan for what they are actually using their SUV for.
What are the positive effects of making electricity from fossil fuels?
Fossil fuels provide a reliable and consistent source of energy that can meet high demand. They are also relatively affordable compared to other energy sources, making electricity more accessible to a larger population. Additionally, advancements in technology have helped reduce emissions and improve the efficiency of fossil fuel power plants.
How does Air pollution cause chemical weathering?
Air pollution can cause chemical weathering by releasing acidic gases such as sulfur dioxide and nitrogen oxides into the atmosphere. These gases combine with water vapor to form acid rain, which can react with rocks and minerals on the Earth's surface, leading to their dissolution and weathering. Over time, this process can weaken and break down rocks, contributing to erosion and the reshaping of landscapes.
