Environmental Pollution Phenomenon

Environmental Pollution Phenomenon: there are various phenomenon such as:

Acid Rain: Acid Rain is a form of air pollution in which airborne acids produced by electric utility plants and other sources fall to Earth in distant regions. The corrosive nature of acid rain causes widespread damage to the environment. The problem begins with the production of sulphur dioxide and nitrogen oxides from the burning of fossil fuels, such as coal, natural gas, and oil, and from certain kinds of manufacturing. Sulphur dioxide and nitrogen oxides react with water and other chemicals in the air to form sulphuric acid, nitric acid, and other pollutants. These acid pollutants reach high into the atmosphere, travel with the wind for hundreds of miles, and eventually return to the ground by way of rain, snow, or fog, and as invisible "dry" forms.

Damage from acid rain has been widespread in eastern North America and throughout Europe, ana Japan, China, and Southeast Asia. Acid rain leaches nutrients from soils, slows the growth of trees, and makes lakes uninhabitable for fish and other wildlife. In cities, acid pollutants corrode almost everything they touch, accelerating natural wear and tear on structures such as buildings and statues. Acids combine with other chemicals to form urban smog, which attacks the lungs, causing illness and premature deaths.

Ocean Acidification: Ocean acidification is the continuing phenomenon of decreasing pH in the world's oceans. Between 1751 and 1994, ocean pH is estimated to have decreased from 8.179 to 8.104 (decrease of 0.075). Ocean pH is expected to decrease by a further o.3-0.5 by 2100. This acidification is mainly the result of uptake of carbon dioxide from the atmosphere. The world's oceans naturally absorb carbon dioxide from the atmosphere, indirectly mitigating climate change. Ocean acidification adversely affects marine organisms especially calcifying organisms like corals, crustaceans and molluscs, and also affects other organisms by entering the food chain.

Soil Salination: Salt affected soils are caused by excess accumulation of salts at the soil surface. Salt can be transported to the soil surface by capillary action from salt-laden water tables, or by human activity. Increasing soil salinity adversely affects soil quality and vegetation. Human activities that increase soil salinity include land clearing; aquaculture activities; and irrigation (over a period time causes deposition of salts). The adverse effects of salination include

  • loss of soil fertility
  • damage to infrastructure (such as roads etc)
  •  damage to plant growth and yield
  • deterioration of underground water quality
  • soil erosion
