Pollution

Pollution is the process of giving out contaminants such as smoke and carbon dioxide, and too much of a certain product such as light, heat and sound that both cause harm to the environment.

How are cyanobacteria being used to reduce levels of pollution?

Bioreactors

"While most antipollution technologies involve massive, complex equipment, some scientists are experimenting with tiny, simple living organisms called cyanobacteria that eat polluting carbon dioxide (CO2). These algae can flourish in the blistering temperatures of chimneys. Researchers have designed "bioreactors," window-screen-like membranes teeming with cyanobacteria, for future installation into power plant smokestacks. Fiber- optic cables would focus life-sustaining light across the membranes, allowing the algae to grow inside chimneys while feasting on a diet of CO2 exhaust. This technology has already proved itself in small-scale demonstrations. A test on a fully operational power plant is about five years away, and scientists are also studying the same algae as a potential source of hydrogen energy." (NOVA)

Easy traffic jam?

An easy traffic jam could be due to a car driving slower than the rest of the cars.

How is acid rain made in a easy way of saying it?

acid rain is made by pollutants in the air that give the the rain an acid or vinegar like feeling acid rain destroys plants animals and buildings

How should you dispose of an old thermometer?

It depends on the thermometer. If the thermometer is made of glass and filled with a silver liquid, that liquid is mercury. Your local environmental protection organization might be able to tell you where you could safely dispose of it. Otherwise, you might check with companies that deal with scrapping out old cars, which contain mercury switches, or fluorescent bulbs, which contain mercury.

If the thermometer does not have a silver liquid in it, it doesn't contain much or any mercury, and it should be possible to toss it with your normal household trash. When a glass thermometer has a red or blue liquid, the liquid is alcohol or, rarely, some other organic liquid such as kerosene. It's not that much of a threat. Metal coil thermometers with dial pointers are just scrap metal when you need to dispose of them. Electronic thermometers have batteries, which might have some mercury but might not. If in doubt, take the battery out and put it in a battery recycling bin. If you must throw it out in the trash, at least the amount of mercury in it (if any) will be small. The circuits themselves contain the same contaminants and heavy metals that any piece of electronics would, but since the amount of circuitry in an electronic thermometer is small, the amount of waste in one is small also.

How does smog affect plants?


ground-level ozone can disrupt photosynthesis, meaning plants do not make their food. it can also turn the leaves brown and cause the leaves to die, harming the plant.

particulate matter can reduce visibility (create haze), reducing sunlight that can reach plants. it can be carried on the wind, settling elsewhere. It can deplete the natural minerals found in soil that plants need.

nitrogen oxides (NOx) helps to create ground-level ozone, and can also combine with other organic chemicals in the air to make some toxic chemicals. NOx is also a component that creates acid rain, which can damage plant leaves. Acid rain slows the growth of plants, and in extreme cases can kill the plant. Acid rain also causes some other metals/minerals (say, from car's paint or stone buildings) to leach into the soil, which may harm the plant. Acid rain also helps to wash out of the soil important minerals the plant may need to develop. NOx is also a greenhouse gas, which can cause climate change. NOx also reduces visibility/transmission of light, meaning that plants have less solar energy to use to produce food through photosynthesis.

Sulfur dioxide also causes haze, and is a component in acid rain.

Carbon monoxide helps to create ground-level ozone.

Can you give me points on causes and effects of pollution?

One negative point of pollution is that it contributes to Global Warming. One positive point toward pollution is that it helps animals become strong to survive it.

Will you get sick if you live near a power plant?

Yes you could it is possible you could get heart disease or lung cancer if the power plant has anything to do with radiation or smoke coming out from a tower.

Name four things polluting Africans waters?

Pesticides, fertilizers, human waste, storm water runoff, mining, and manufacturing byproducts all contribute to water pollution in africa.

How is the allowance trading system used to reduce air pollution?

The EPA sets allowances for the amount of a pollutants that companies can release, and it fines companies that exceed their allowances

How do you think nations should resolve air pollution problems that cross national boundaries?

They could chicken out and let the world be destroyed by air pollution and all those nasty dirty gases that are floating in the air caused by people. Or they could make new and strict rules about saving the world by recycling, using less cars, and using alternative forms of transportation. The nations could help by making serious strict rules about changing the world.

How do we as a society contribute to water pollution?

As a society we pollute water by throwing trash into rivers, drilling for oil, and by mining for coal.

Is breathing smog harmful?

Long term exposure to smog laden air can lead to various lung conditions such as asthma, bronchitis, emphysema, and even lung cancer, (depending on what is in the air). Short term exposure can exacerbate asthma and/or bronchitis, wearing a mask can help some but many components of smog are too small to be filtered by most masks. During a smog alert people with cardiac or respiratory conditions are cautioned to remain indoors, air conditioned buildings offer some protection.

Solution of air pollution from factories?

the goverment cut down on factories opening times.

What is burial of drums of toxic wastes water or land pollution?

depends where you dump it dumbazz, if u dump it in water = water polution

land= land pollution............. DIPSHIV

What will happen if littering continues?

the earth will be dirty and property will be worthless. there will be many floods form the clogging of sewers.

Is Acid rain created when water vapor in the atmosphere absorbs carbon dioxide?

Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides, which react with the water molecules in the atmosphere to produce acids.
