Following are some of the impacts of soil pollution: Soil pollution decreases soil fertility. Loss of soil fertility makes the soil inhabitable for plants and other organisms. Soil pollution has adverse effects on soil microbial population that plays important role in soil formation and keeping it fertile. Indiscriminate use of agro-chemicals destroys the soil flora…
Soil is a natural medium of inorganic and organic nutrients and has an inbuilt system of spontaneous recycling of matter. It is affected by changes in the atmospheric conditions as well as water contents and microbial population. Soil pollution is defined as an undesirable change in the natural, physical, chemical or biological components of the…
It is very hard to control thermal pollution because it is the results of actions of many people. But in case of already known source location, the water should be allow to cool down before discharged. The cooling towers and fountains can be used for the rapid cooling. Large tank and reservoir should be constructed…
Some of the major adverse effects thermal pollution on aquatic life are as follows: Small animals, phytoplankton, zooplankton, small fishes get affected and killed by the hot water. Cell walls of such type of animals and plants severely damage due to the hot water. Hot water may adversely affect the enzyme and metabolic activities of…
Several industries, thermal power plants, and nuclear power stations use large quantity of water as a cooling agent, resulting heating of water after the absorption of excess of heat from these processes. In the thermal power plants about 70% of the heat is lost as waste which is absorbed by the cooling water. The water…
The water pollution due to the heat is popularly known as thermal pollution. Hot water from different sources when enters into the water bodies affects the water bodies adversely. Both plant and animals get affected by such type of the pollution.
Approximately 33 percent of water pollution is by domestic sources, followed by agriculture- livestock with 29 percent, 27 percent by industry and 11 percent from other sources. Water Pollution Sources 1. Domestic Domestic sewage is wastewater generated from the household activities. It is 99.9 percent pure water; remaining 0.1 percent are pollutants which are both…
Nearly 50% of all marine pollution is caused by sewage and wastewater discharge. Annually, about 400 billion tons of industrial sate are produced globally, bulk of which is discharged untreated into the streams, rivers, seas, oceans and other water bodies. Water pollution means one or more substances building up in aquatic bodies to a limit…
The nuclear hazard can pose a great threat to the environment according to spread of radioactive radiations. These are: The radioactive substances are known to be hazardous and when released in environment can disperse or accumulate in living organisms by passing from one trophic level to another in a food chain. One of the radioactive…
