Where does air pollution come from?
A breakdown of the sources of many air pollutants that damage our health and ecosystems.
This has been a major environmental problem because acid rain can change the chemistry of rivers and lakes, affecting fish populations, soils, and the extent and quality of forests. Although NH 3 doesn’t stay in the atmosphere for long — typically hours to days — it can react with other gases to form small particulates that harm human health. Non-methane volatile organic compounds (NMVOCs) can threaten human health through all three of the pathways we looked at earlier: they can be directly toxic in high concentrations and mix with other gases to form ozone and small particulates.
