Detailed explanation-1: -The main problem is that scientists don’t have enough information on actual exposure and on how toxic air pollutants harm human cells. The exposure assessment often relies on computer models when the amount of pollutant getting from the source(s) to people can’t be easily measured.
Detailed explanation-2: -Different people react differently, and there are a number of confounding factors including Individual Health, Occupation, Pollutant mix, and Activity. This makes it difficult to prove cause and effect.
Detailed explanation-3: -What are the health consequences of air pollution on populations? Exposure to high levels of air pollution can cause a variety of adverse health outcomes. It increases the risk of respiratory infections, heart disease and lung cancer.
