In the automobile exhaust includes hundred kind of different compound, pollutant has the solid suspended particle, the carbon monoxide, the carbon dioxide, the lead and the sulfur oxygen compound and so on.Passenger vehicle year emissions harmful waste gas compared to own weight big 3 time of, ...
How is air quality measured? TheNational Weather Servicesays that the Environmental Protection Agency calculates the Air Quality Index – a value between 0 and 500 – based on five "major pollutants." Those pollutants — ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide and n...
in our cities, it is a very aggressive pollutant, and we’d rather not see it there ! The tropospheric ozone (the troposphere is the lowest layer of the atmosphere, the one that “touches” the ground) is a classical component of air pollution, and indirectly comes from hydrocarbon combusti...
Air pollution is the contamination of air in our atmosphere by harmful gases and particulate matter that is not naturally found in the air. Air pollution is caused by many different sources, including the burning of fossil fuels, vehicle exhaust and industrial processes. ...
combination of pollutant gases. Sulfur dioxide is the one chemical what is often associated with acid rain. 【S5】___ It is mainly emitted by large coal burning power stations. It affect places thousands of miles away as 【S6】___ well as areas around the power stations. To prevent more...

When fossil fuels are burned to power vehicles, power plants, and factories, theyrelease nitrogen oxides, VOCs, and other pollutants into the air. Then, as sunlight hits the nitrogen oxides and VOCs, it causes a chemical reaction that creates another pollutant: ozone. As long as there’s sun...
The Shipping Industry: The greatest source of global carbon emissions? There are various emissions from the ship which are responsible for ozone depletion greenhouse effect as well as human health due to this pollutant by the seat meaning premature death respiratory and cardiovascular disease were repo...
For example, sulfur dioxide has detectable health effects at 0.08 parts per million (ppm), which is about 400 times its natural level. Carbon monoxide, however, has natural level of 0.1 ppm and is not usually a pollutant until its level reaches about 15 ppm. (选自New Scientist)The ...
It also tells you what pollutant is causing issues, who is most at risk for health complications and what activities may be safe to do. In New York City, for example, the Thursday morning reading said the AQI for PM2.5, a kind of particulate matter, is 215, meaning "very unhealthy," ...
