A substance in the air that can cause harm to humans and the environment is known as an air pollutant. Pollutants can be in the form of solid particles, liquid droplets, or gases. In addition, they may be natural or man-made.[2]
Pollutants can be classified as primary or secondary. Usually, primary pollutants are directly emitted from a process, such as ash from a volcanic eruption, the carbon monoxide gas from a motor vehicle exhaust or sulfur dioxide released from factories. Secondary pollutants are not emitted directly. Rather, they form in the air when primary pollutants react or interact. An important example of a secondary pollutant is ground level ozone - one of the many secondary pollutants that make up photochemical smog. Some pollutants may be both primary and secondary: that is, they are both emitted directly and formed from other primary pollutants.
Major primary pollutants produced by human activity include:
Secondary pollutants include:
Minor air pollutants include:
Persistent organic pollutants (POPs) are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes. Because of this, they have been observed to persist in the environment, to be capable of long-range transport, bioaccumulate in human and animal tissue, biomagnify in food chains, and to have potential significant impacts on human health and the environment.
A polluted gas is a gas that contains harmful or toxic substances, such as pollutants or contaminants. These gases are often released into the atmosphere through industrial processes, vehicle emissions, or natural sources like volcanic eruptions. Examples of polluted gases include carbon monoxide, sulfur dioxide, nitrogen oxides, and volatile organic compounds.
you would evaourate the water until it is no longer there!!! then you have polluted the air with gas!!!
oxygen
because the polluted atoms
Its all three
the polluted gas or pollted waste emitted from nuclear stations.
where does the gas go
places that can't be polluted by humans are: earth's core, sun, Venus, the three gas giants, a star, a black hole and outer space.
Coal is the most polluting, then oil, then natural gas.
Many people in big cities breathe polluted air. Why? - the pollution is mixed with the air you breathe. =============================== "Can you breathe it?" is not the question you want to ask. You can breathe anything that's in the form of a gas, or particles dispersed in gas ... carbon dioxide, helium, carbon monoxide, steam, nerve gas, tobacco smoke, alpha-particle plasma, etc. For any gas, the question you want to ask is "How long can you survive while you breathe it ?" You cannot survive as long breathing polluted air as you can survive breathing clean air. In other words, polluted air kills people. Not in a minute, not in an hour, and not in a day. But people don't live as long in polluted air, and that's exactly the same as saying that polluted air kills people.
The waters are polluted in rivers,lakes,ponds and sea's. The reason is because people are throwing things there not ment to in the rivers etc. Or that the factories produce gas in the air and that goes to the river :)
Gas masks are used when the air is polluted so they give you fresh air. They are often used when there is toxic gases around.
Ride cars that consume gas and put other chemicals in the air
