Acid rain is very harmful to life. It’s from the atmosphere containing of nitric and sulphuric acids and it’s a mixture of wet and dry deposition.

Acid rain affects us in many different ways. One major way is our health. Children and adults who have asthma or breathing problems have been linked to acid air pollution. Everything we eat, drink and breathe has at one time come in contact with acid deposits. The following health problems occur each year in the U.S. and Canada due to acid rain. -55 premature deaths -1,520 emergency room visits -210,070 asthma symptom days

Two chemical gases are released into the atmosphere, these are sulphur dioxide and nitrogen oxides. Those two chemicals are reacted with water, oxygen and some substances to form mild solutions of sulphuric and nitric acids. In the winter the acidic solutions spread across and move in a really fast pace. This is because the winds spread these acidic solutions, by blowing them into the atmosphere. Then it starts raining.

Burning gasoline, oil and wood releases carbon monoxide. Once it enters your bloodstream you will feel dizzy, get headaches and fatigue. This is because the carbon monoxide slows down the delivery of oxygen to your body.

Acid rain begins with emissions into the atmosphere sulphur dioxide and nitrogen oxide. Which are released by cars, industrial processing such as smelting substances down, refining and electric power plants that burn fossil fuels such as coal and oil. The gases mix with water vapour from the clouds which creates sulphuric and nitric acids. This makes rain highly acidic.

Places in south east Asia, western south Africa, Southern India and Sri Lanka and even West Africa could all be prone to acidic rainfall in the future.
