What are some air pollution quotes?

  1. "The Earth does not belong to us: we belong to the Earth." - Marlee Matlin
  2. "Pollution is nothing but the resources we are not harvesting. We allow them to disperse because we've been ignorant of their value." - R. Buckminster Fuller
  3. "The greatest threat to our planet is the belief that someone else will save it." - Robert Swan

What negative effects do sulfur dioxide have on the environment?

Sulfur dioxide dissolves into the water particles in the atmosphere, and reacts with the water to form sulfuric acid and carbon dioxide. This builds up in clouds, and eventually falls as acid rain. Sulfur dioxide can also cause a very minor greenhouse effect, but it is not noticeable and can be dismissed in many calculations.

Typical PH for rain is 6.2. Acid rain as low as 4.6 has been recorded in dirty major cities. Coal powered electric generators are the primary cause of this pollution. The United States has had scrubbers on their systems for decades to elimainate this issue.

The number one country for sulfur dioxide generation is China. The produce over 40% of the world's sulfur dioxide. Currently no one is requesting (or demandoing) that they clean their act up.

Does sand pollute the ocean?

Sand itself is a natural part of ocean ecosystems and does not typically pollute the ocean. However, human activities such as dumping trash and plastic waste on beaches can lead to pollution of the ocean.

Which one of the following would you classify as public enemy number 1 in terms of a pollutant health hazard?

It would depend on the context and location, but globally, air pollution from vehicles and industrial activities is often considered a significant health hazard due to its widespread impact on respiratory health and potential for long-term health effects such as heart disease and cancer.

What country has the least CO2?

countries like Australia and new zealand are effected least because they have a small area of land. this is because the rays reflect off the water but don't reflect off the land. big masses of land like the usa and Canada (joined as 1 big mass) have more global warming because they arnt really surrounded by water. hope that helps and you kinda get it

What method of treating water kills microbes and removes other contaminates such as heavy metals?

No one method does both of these things optimally.

For drinking/potable water supplies:

* Killing microbes (bacteria, protozoa, etc.) is done with disinfection using chlorine, bromine or UV light or thermal treatment. * Heavy metals removal can be don with reverse osmosis, activated carbon filtration, deionization, coagulation precipitation and filtering, or distillation. Distillation is generally reserved for small amounts of water not municipal supplies. For swimming pools heavy metals are not a major concern and only disinfection is used.

For treating water (sewage or industrial wastewater) before discharge to a watercourse disinfection and filtering is generally used . The majoriyty of metals are asorbed by the activated sludge and can be removed as any solid.

What is an air pollutant?

Mostly HNO3 (Hydro nitrogen trioxide) this is the main one and also along with CO1/2/3 SO1/2/3 which are Carbon,Monoxide, Dioxide, Trioxide and Sulfur Monoxide, Dioxide, Trioxide.

Which tree absorbs more CO2?

Deciduous trees are generally thought to inhale more carbon dioxide than other trees. It's because deciduous are usually broad leaved, so they are more efficient in photosynthesis. Here is a list of some trees that take in a lot of carbon dioxide: English Oak

Common Lime

Horse Chestnut

Common Alder

What will happen if the greenhouse effect continues?

The climate is always changing, but the effects of anthropomorphic gases will accelerate some changes. About 19% of the world's glacial ice is located above Greenland. As the temperature increases, this ice is likely to slough into the Atlantic, raising the world's oceans about 20 feet. I once read that about half of earth's human population lives within 20 feet of sea level.

What happens next is more difficult to guess. The extra surface area available for evaporation could create more cloud cover, reflecting light to ultimately cool the earth again. All the fresh water might turn off the north Atlantic conveyor, which would also likely contribute to cooling. Whatever the effects, they will be long term.

Soot from coal fired plants increases earth's albedo, increasing the temperature. However, soot settles out within a single year. CO2 emissions linger about a thousand years, so the effects we are accumulating now will last for many generations.

What are 3 effects of acid rain?

- kills fish/ animals.Some animals that live in water bodies such as mayfly are very sensitive to changes in Ph.They cannot survive in water whose Ph drops even by a fraction. - erodes buildings.The acid in the acid rain reacts with building materials such as some rocks like limestone and reactive metals.The components found in rocks like limestone are dissolved slowly eroding the rock.Similar things happen to the metal material.They react with the acid rain causing it to erode.

- Effects on plants.Acid rain attacks the waxy coating on the surface of the leaf of a plant.

About how many oil spills happen each year?

This number is unknown as not all oil spills are reported, and many are not required to be reported under current legislation. The circumstances of the spill (indoors or out, contained or uncontained, in barren areas or in sensitive areas), the magnitude of the spills (drips or Mega liters), and the reporting jurisdictions requirements all affect reportability. Industrial associations and environmental agency data often provide spill numbers that meet their criteria.

How many individual decontamination packets should be in your M295 Equipment Decontamination Kit?

There are 12 individual decontamination packets in the M295 Equipment Decontamination Kit.

What gases do petrol cars emit?

The majority of gaseous emissions from motoer vehicles origine from the engine. There are however other sources:

From the engine/exhaust:

* Water * Nitrogen * CO2 * CO * NOx * Unburned petrol (Butane to Octane + and aromatics) * Carbon particulate * Aldehydes/Ketones * Benzene * Light hydrocarbons From Fueling:

* Petrol Vapour (Butane to Octane + and aromatics) From the Interior: * Plasticizers * PAH Others:

* Ethylene Glycol (cooling system) * Freon or HCFC (AC) * Hydrogen (battery) * Ozone (electrical system)

Do trees absorb greenhouse gasses?

Yes, trees absorb the powerful greenhouse gas of carbon dioxide. Photosynthesis is the process where all vegetation absorbs CO2 from the air, store the carbon and release the oxygen. So forests are carbon sinks, that is storage areas for carbon. This is why afforestation is important so we can slow and stop global warming.

Identify two ways the m295 equipment decontamination kit is used to decontaminate equipment?

The M295 kit decontaminates equipment by neutralizing chemical agents with reactive compounds and physically removing contaminants with absorbent materials. It also includes tools for scrubbing and washing equipment to ensure thorough decontamination.

Is oil environmentally friendly?

Oil is very useful, and is used everyday. But if oil is spilled, for example in the ocean. Then it can have an extremely harmful affect on all aspects of aquatic life. Birds' feathers are covered in the oil which ruins the feathers insulating powers. The birds then die from hypothermia. It also ruins corals.

Hope this was helpful. If anyone knows more information, then please feel free to add. :)

Is smoking pollution more harmful than a cars pollution?

Smoking pollution can be more harmful in some cases due to the concentration of toxic chemicals in secondhand smoke and the close proximity to individuals who may be affected. However, car pollution can have a broader impact on air quality and contribute to environmental issues such as climate change. Both sources of pollution are detrimental to human health and the environment.

What are the causes of oil pollution in Venezuela?

Oil pollution in Venezuela can be caused by oil spills from oil rigs, tankers, or pipelines. The lack of proper maintenance and infrastructure, as well as inadequate regulations and enforcement, can also contribute to oil pollution in the country. In addition, political instability and economic issues in Venezuela may hamper efforts to prevent and address oil pollution effectively.

Which is more dangerous point pollution or nonpoint pollution?

Point pollution is when the pollution happens right there, where the factory chimneys are, where the oil pipe breaks, or the oil tanker crashes, or the nuclear power plant explodes. The pollution is at the point where it happened.

Non-point pollution is when the pollution happened somewhere else. Fumes escape from cars on the highway. The oil tanker crashed up there, but the pollution ran across the roads and landscape and into the ditch and into the waterways and into the ocean. The pollution ends up at the non-point where it happened.

You can't say which is more dangerous, because it depends what the pollution is. A nuclear accident is usually more dangerous at point because the radiation weakens as it moves further away from the source. Oil pollution is damaging at point, but is more dangerous if the oil gets into the waterways and oceans where it can do a lot of damage. Pollution from a coal-burning power station is huge and constant.

How does man pollute the environment?

Humans pollute the environment through activities like burning fossil fuels, deforestation, industrial processes, and use of chemicals in agriculture. These actions release harmful substances into the air, water, and soil, leading to air and water pollution, habitat destruction, and climate change.

In what year did water pollution begin?

Human pollution of water has historicaly begun in an environment as soon as human activities are introduced to it. Do you not pollute water just by being in it? Of course, the bulk of water pollution due to human beings arose with the industrial revolution, as factories sprung up globaly. Intentional pollution of a water source could have been used as a means of attacking an enemy since the advent of warfare, and could have even occured prehistoricaly.

What was the pollution was in the high Middle Ages?

The Middle Ages was very polluted because no sewers of trash services were created.

People mostly just threw out there trash and sometimes on people walking by.

I hope this helps!

How do you prevent the oceans from being polluted?

I don't know much, but with all the plastic garbage thrown in our ocean, maybe cut down on your plastic consumption, recycle what you do use, and if possible maybe try volunteering for clean up. I know there are other ways, so just keep researching it.

How does pollution hurt people?

Contaminating drinking water, killing and poisoning water-based food resources, and poisoning recreational waters are ways that water pollution affect people. Pollution can make water life-threatening to drink and to boat, fish, snorkel or swim in. It also deforms, kills and toxifies food sources -- such as fish, seaweed and turtles -- for people, pets and wildlife.
