explain the effect of pollution on human health
Answers
Answer:
Air pollution is considered as the major environmental risk factor in the incidence and progression of some diseases such as asthma, lung cancer, ventricular hypertrophy, Alzheimer's and Parkinson's diseases, psychological complications, autism, retinopathy, fetal growth, and low birth weight
Answer:
There are two types of air pollutants, primary and secondary. Primary pollutants are emitted directly from their source, while secondary pollutants are formed when primary pollutants react in the atmosphere.
The burning of fossil fuels for transportation and electricity produces both primary and secondary pollutants and is one of the biggest sources of air pollution.
The fumes from car exhausts contain dangerous gases and particulates including hydrocarbons, nitrogen oxides, and carbon monoxide. These gases rise into the atmosphere and react with other atmospheric gases creating even more toxic gases.
According to The Earth Institute, the heavy use of fertilizer for agriculture is a major contributor of fine-particulate air pollution, with most of Europe, Russia, China, and the United States being affected. The level of pollution caused by agricultural activities is thought to outweigh all other sources of fine-particulate air pollution in these countries
