Study Notes
Acid Rain
- Acid rain is harmful to the environment and human health
- Acid rain washes away essential nutrients and minerals from the soil
- Soil biology and chemistry are damaged, some microbes are killed
- Acidic water damages plants, harming bark, leaves, and root hairs.
- Affects agricultural production, crops like barley, cotton, and fruit trees are badly affected.
- Lowers the pH of waterways harming marine wildlife
- Most aquatic animals cannot survive in water with a pH less than 4
- Some fish species die when pH drops below 5.5
- Metals corrode easily when exposed to acid rain
- Textile, leather, and paper products lose strength or disintegrate
- Human health can be affected by acid rain- impacting nervous, respiratory and digestive systems.
- Wipes out beneficial bacteria and algae, disrupting ecosystems
- Building materials (marble, limestone, etc.) are weakened
Formation of Nitric Acid
- Nitrogen and oxygen from the air react at high temperatures to form nitric oxide (NO)
- Nitric oxide is further oxidized by oxygen in the air forming nitrogen dioxide
- Nitrogen dioxide interacts with rainwater forming nitric acid
Reducing Acid Rain Impacts
- Reduce burning of fossil fuels and use alternative energy sources (hydroelectric, solar)
- Fit catalytic converters to vehicles to reduce nitric oxide emissions
- Use coal and petroleum with low sulfur content
- Employ air filters, scrubbers, and smoke precipitators to control industrial air pollution.
