What are the main problems when plastics are burned in landfill sites?
Plastic is not digestible. So creatures will wind up eating it, but they can't digest it. The elements from which it is made will not be usable by the ecology. This is a bigger problem in the oceans than it is in landfills. Plastic breaks down eventually, into small particles, but those particles remain indigestible. This is bad for the ecosystem.
If your pool has had shock treatment to remove algae what could be another cause of a green pool?
It could still be yellow or mustard algae. Chlorine is not always the only antidote to an algae bloom. You must use an algaecide, as well. Copper- and silver-based varieties are effective. When the algae is dead and sinks to the bottom, it may appear grayish in color. Vacuum that out to waste. If the green stuff is only on the bottom and not forming on the ladder, skimmer parts, walls, etc., perhaps you don't have an algae problem. Perhaps you have a calcium problem. Does the greenish stuff "poof" and easily disperse when you disturb it with the vacuum head or a brush attachment? Is the water generally clear except for the ick at the bottom? If so, it could be calcium buildup. If you use a calcium-based chlorine product and have been doing so awhile, then it's quite possible your problem is calcium. You need to very carefully vacuum that precipitate out to waste, replace the water you ejected with fresh water, and switch to a non-calcium-based product. The answer above neglected to mention an important part of the pool - THE FILTER. Without the proper length of filter run time you will get nowhere in having a clear, quality pool.
What are the 4 characteristics that make hazardous waste hazardous?
they are really bad and they can kill
How long does it take carboard to decompose?
Depending on conditions cardboard, in a normal garden environment will decompose in a few months. If shredded or mulched and properly treated, in about three months.
Kept dry, stacked with little surface area exposed and away from soil, then it could take many years.
What are the environmental problems with plastics?
Plastics have extremely long half-lives in landfills. They can also be hazardous to wildlife (choking hazard, digestive blockage, or other hazard such as is seen with dolphins and plastic rings). Also as they degrade they release hydrocarbons, which is added to the carbon cycle. The answer can also be:
They are non organic substances and hence the various microorganisms that decay matter can not act upon the plastics and hence the do not decay in nature. They pollute the environment. In other words they do not rot. When kept in landfills they still are bad for the environment because of this and as most of our waste ends up in landfills they take a lot of space. Burning them will also create pollution releasing toxic gases.
What are the ways to control air pollution?
There are several ways to control air pollution. One way is to use public transportation or carpool with others to reduce emissions from cars. Another way is to reduce power consumption by limiting use of the air conditioning.
You must get permission if you plan on running background checks on possible employees. If you are opening up a new restaurant it would be best if you included the fact that you plan on running background checks on you application, thus clearing you from any right violations in the future.
How is landfill waste disposed?
A final cover of impervious clay is applied followed by a layer of topsoil to allow for grass or tree growth. A monitoring system for air or water contaminants may be added.
A landfill eventually becomes a park or open space with zoning to prevent activities that would endanger the site's integrity.
Why is recycling is not good for environment?
Recycling is not bad for the earth. It is good for the earth.
- Recycling paper means we don't have to cut down so many trees.
- Recycling aluminum means we don't use so much energy producing new cans and products, and we don't have to dig so much out of the ground, where it's getting scarcer anyway.
- Recycling plastic uses less energy than it takes to make it from its base material, which is oil. The world is rapidly running out of oil.
- Recycling glass saves energy as it is much easier to make new bottles from broken glass than from the original ingredients.
All these things mean we use fewer natural resources and we don't put so much carbon dioxide, a greenhouse gas, into the air where it contributes to global climate change.
Well I wouldn't say recycling is bad for the earth, I mean it is good, but some parts are bad. Like for example all the extra bins you have in your back garden, One for normal rubbish, one for tins, glass etc, paper basket, food waste and a garden waste one, and all of these extra bins means more trucks coming to pick them up. :)
How long does it take for plastic to degrade?
"Plastic" is not a specific chemical compound. Some "plastics" are specifically designed to be biodegradable; these usually break down fairly rapidly. Others are not and don't. Even if you named a specific chemical compound, the question is essentially meaningless; what does "break down" mean? To what extent does the material need to degrade before you consider it "broken down"? What conditions are we talking about (it matters very much whether it's in a dark, dry, cool environment or a warm, moist one with plenty of UV radiation)?
How long does it take polythene to decompose?
Most of the polythenes are not in the food cycle of microorganisms which decompose materials. generally it takes 2 to 5 years for a single piece of polythene to start getting decomposed, can take upto a decade for complete decomposition!
What are two ways in which environmental resources are important to human health?
Water and sunlight
Water is very essential to our health it flushes us out and keeps us hydrated. are are about 85% water.
Sunlight- helps our bodies produce Vitamine B which allows our bones to absorbe calcium. With out vit B we are unable to absorbe calcium. Sunlight also makes photosynthesis which makes plants grow to produce O2 and provides food for us and our livestock.
What are the disadvantages of reusing materials?
collection of recyclables is a tedious affair. Each household must sort and have suitable containers for rubbish and recyclables. the recyclables must then be further separated into glass plastic metal and so on, and placed in separate containers.
Rubbish usually ends up in a landfill. Some local councils separate rubbish into recyclables, organics and rubbish. Recyclables are recycled, organics go into compost or a methane producer and rubbish then goes to landfill.
Why do you need waste management?
waste managemaent is necessary because if it is not done the waste may lead to environmental and health problems harmful for mankind. Our planet is going to be filled with waste soon if we don't manage our garbage and trash properly. Even though at some point some people (even us) don't notice this kind of damage we have for the environment, this might show up at the times when our kids are the ones occupying our planet.
What are ways to reduce trash we dump in landfills?
By watering the garbage down?
Answer:
This question demonstrates the difficulty in arriving at a correct answer rather than an expedient answer for pollution problems. In the question the resolution of garbage problems creates air pollution problems. In the first answer the resolution of air problems creates water problems and so on.
Assume you're presented with the garbage problem for the first time. If the original question is: The garbage is piling up around town, what should we do?
The simple answer is haul it away and pile it somewhere. Out of sight out of mind!
The garbage festers, stinks, breeds clouds of flies and hordes of rats. So the answer is - set it on fire. Which generates smoke, more odour and hordes of rats (singed) fleeing into town. So - dump water on it to put out the fire, at which point the water flows into the town's water supply (aquifer or stream) and creates even more problems.
The wise town sanitary engineer should sit down with the original question and write down a list of garbage problems which he has to solve:
- We've got garbage
- Garbage attracts rats and breeds vermin no matter where it is
- Rotting garbage stinks
- Garbage catches fire or can be set on fire which creates smoke and the smell of toasting garbage
- Water going through garbage is like water through tea, a lot of stuff is dissolved out tainting other pure water
Having done this he sets out a list of suggestions that would address each part of the problems:
- Let's gather it up and haul it away - but remove the clean and useful stuff (e.g. metals) first to reduce the volume. This cuts our work and returns a profit.
- Let's bring it to a site where it can be separated from the groundwater like a nice clay lined pit.
- Let's control where garbage is put so the pit fills up in a systematic fashion.
- Let's compact the day's garbage each day and cover the day's garbage with a layer of impervious clay to stop water (rain) from getting to it, rats from living in it, fires from getting started and smells from escaping.
- If we do want to burn some of it (wood waste. paper etc.) let's do it in a proper incinerator to minimize smoke and smells and capture the heat to make steam or heat homes.
- When the pit is full, we'll build another. The old pit will be sealed off with clay then covered with topsoil to make a park. (Garbage disposal leads to urban betterment)
____________________
When I first read the question, I thought you might be asking about how to get rid of a bad odor coming from your kitchen sink garbage disposal...just in case that was it, grinding small pieces orange or lemon peels can help, so can putting a little baking soda in the drain and then drizzle some vinegar in until you see it begin to foam...that will make it smell much better too. Rinse after the foaming action stops.
What are the functions of a water treatment plant?
They pump in raw untreated water from a well, lake or river. Remove the odor and bad taste by aeration (a natural process) remove setable solids (another natural process), disinfect the water, adjust the PH of the water, filter the water (another natural process), then pump it out for your use.
What is an effective to chlorine for disinfecting waste-water in a municipal treatment plant?
Chlorine is used to kill harmful pathogens in the treated sewage before discharge to a receiving watercourse. This is similar to its use in swimming pools. Similar treatment can be provided by using bromine, ozone or ultraviolet light.
What are biodegradable wastes?
Examples of non-biodegradable include glass, plastics, rubber, tires, etc.
Why should chemical waste be treated before throwing it in the soil?
chemical waste is any identity which shifts the ecological equilibrium as the outcome of its chemical reactivity or or chemical stabilty.the reactiveines need to be destructed or added with ligands to make them inactive and the soil slowly compilesthem into cycle eg industrial effluents of paint industry the other are stable ones likes ddt that show biological magnification need to be estructed as only treatment .. this preflux lysis or chemiacal addition is treament so that it insures no or less effect on ecological equilibriums nishantstag@gmail.com
Water pollution is the presence of any material in the water that is harmful to plants or animals, or affects its taste and odor, or detracts from any use that can be made of it.
Yeah=] Das really Da Answer =] ILY<333
contaminated water whether from chemical,particulate or bacterial matter that degrades the water quality and water purity.Water pollution can occur in oceans ,rivers ,lakes and ubderground resoivers.
addition of foreign substances (pollutans) in the water
How are other animals affected by water conservation?
Water conservation ensures that other animals have access to clean water. This makes it possible for such animals to thrive in a given area.
How long does it take a plastic cup to break down?
Most plastics break down more quickly when exposed to sunlight than when buried. The exact time will depend on the type of thickness of the plastic. Some plastics are being made now that breakdown in about 6 months, others may take 10 years or more.
How many hazardous waste sites are there in the US?
1340
Superfund sites in the US are polluted locations needing a clean-up of hazardous material contamination.
In November, 2010, there were 1280 Superfund sites with 62 sites listed to be added.
