nitric and sulfuric acids". The precipitation that results in acid rain comes from the pollution emitted by human activities‚ such as factories‚ electrical power plants and automobiles. Two main pollutants are sulfur dioxide (SO2) and nitrogen dioxide (NO2)‚ which reacts with substances in the atmosphere‚ such as water and oxygen‚ to form acid rain. While rain water has a pH of 5.6‚ acid rain has a pH of 5 or less‚ which is acidic enough to harm plant life. Due to the reactivity of acid rain‚ the cell

Ohio is one of the many states that suffer from air pollution. Numbers are rising‚ deaths are occurring and many health risks are involved because of air pollution. Different toxins that are being released into our air cause a great deal of concern because this causes many frequent weather changes as well as population issues. People tend to move away from certain areas located near factories which release massive amounts of pollutants daily. There are land issues as well as waterways where contaminants
