Air pollution is measured in terms of the pollutants present in the atmosphere at unnatural levels, negatively affecting all living organisms. Additionally, it may have a negative impact on agriculture harvest yield. Researchers have identified a link between primary pollutants and global climate change. The book also covers secondary pollutants such as ozone. The book discusses ozone chemistry and its environmental health effects. An example is Tropospheric ozone or "bad ozone" is formed by the interaction of various precursors (volatile organic compounds, CO, NOx, etc.) Primary air pollutants These persist in the form in which they are added to the environment. Ozone depletion is caused by chlorofluorocarbons, which makes the ozone layers grow thin. Secondary pollutants are pollutants formed either due to a reaction between primary pollutants themselves or between a primary pollutant and any other atmospheric particle. As temperatures increase in colder regions, the melting snow, ice, and glaciers are contributing to rising sea levels. Primary pollutants are directly generated from human activities like from car, from ships, from construction work etc. Give examples of each.
