Mitigation Strategies And Solutions
...can come from natural sources, such as smoke from a forest fire ignited by lightning or gases from an erupting volcano. However, human activities release many kinds of substances into the atmosphere and contribute greatly to global air pollution. Some of these substances are harmful when they settle on land and surface waters, and some substances are harmful because they alter the chemistry of the atmosphere. Although many different air pollutants exist, we focus on the seven most important types from a regulatory perspective: particulate matter, nitrogen oxides, sulfur oxides, carbon oxides, hydrocarbons, ozone, and air toxics. Air pollutants are often divided into two categories, primary and secondary. The major primary air pollutants are carbon oxides, nitrogen oxides, sulfur dioxide, particulate matter, and hydrocarbons.
Ozone and sulfur trioxide are secondary air pollutants because both are formed from chemical reactions that take place in the atmosphere.
As you can see atmospheric Pollution or air pollution may be defined in many ways, as the introduction into the atmosphere of any material that brings about a negative effect on plants, animals, or people. The effect can vary from lowered visibility at the Grand Canyon to severe pollution outbreaks which can force city residents to stay indoors. Some of the pollutants such as soil, dust, forest fire smoke, and the emissions of volcanoes occur naturally, but most of the air pollution is caused by humans. Air pollution has become a very serious problem all over the world, and is especially a large problem in the large urban areas. Many people suffer from illnesses caused by smog and air pollution in these areas.
All living factors such as plants, animals, and people are all affected by air pollution. Air pollution even causes birth defects. The outdoor air measurements of four pollutants and...
