Pollutants

Pollutants like this derive mainly from the combustion of fuel in car engines.

Some people only buy organic food; they think that in this way their body will not be damaged by pollutants.

Volkswagen's diesel cars emit as much as 40 times more pollutants as they are allowed under the Clean Air Act rules.

This smokestack is releasing greenhouse gases and other pollutants into the atmosphere.

Wetlands also absorb excess nutrients, sediments, and other pollutants before they reach rivers, lakes, and other waterbodies.

Besides global warming, air pollution from the Indo-Gangetic Plains—one of the world’s most polluted regions is also impacting the mountains as these pollutants deposit black carbon and dust on the glaciers, hastening their melting according to the study.

Too much rain, especially in the city, can lead to flooding, causing sewers to overflow and carry pollutants and contaminants to nearby streams and waterways.

A number of pollutants are required to be filtered out from the flue gas of power plants before it can be exhausted to the atmosphere.

They identify methane, tropospheric ozone, hydrofluorocarbons and black carbon as pollutants that could be targeted, with technologies that already exist, to drastically cut their release. Quickly implementing that strategy could off-set warming temperatures by up to 50 percent by 2050, and reduce sea level rise by 22 to 42 percent by the end of the century. Delaying emission cuts would reduce the beneficial impact.

But Indiana University researcher Amina Salamova points out that when the chemicals evaporate, they become toxic air pollutants.
