Pollution In India
Levels of Pollution in India and Around the World
Pollution in India and other countries of the world is a problem that causes health conditions in millions of people each year. There are many types of pollution that threaten our planet every day. Air pollution is probably the most well-known, and involves the release of chemicals into the atmosphere, including carbon monoxide, chlorofluorocarbons, and sulfur dioxide. Many of the chemicals in air pollution are released by vehicles and industries. Soil pollution, or soil contamination, happens when chemicals are spilled on or under the ground, and the main soil pollutants are heavy metals like lead, hydrocarbons, and pesticides. Water pollution is the release of contaminants and waste products into runoff water that finds its way into rivers, lakes, and oceans. Radioactive pollution, while more rare, also causes deaths and disease when radioactive particles are released into the environment. Air, soil, and water pollution are major threats to ecosystems all over the world, and also have devastating consequences for the health of the citizens of many countries.
Air pollution in India, China and other countries causes hundreds of thousands of deaths each year. In countries like India and China where environmental protections and laws against pollution are lax, many industries release dangerous chemicals into the air regularly. Countries with higher population density also produce more air pollution through increased use of motor vehicles. Couple this with lax environmental laws, and the fuel used in these vehicles also causes more air pollution per vehicle than in other countries. Indoor air pollution can also be a problem, as households burn fuels for heat or cooking in improperly ventilated spaces. Air pollution causes lung diseases including lung cancer.
Pollution of soil is a problem for first and third world nations alike. In industrialized nations like the United States, the overuse of pesticides can lead to soil contamination and render the soil unable to support crops. Waste can also leech from landfills into nearby soil, contaminating both the ground and the crops that grow from it. Pollution in India and other countries with high population density can also come from overuse of fertilizers as well as pesticides. Industrial chemical waste can also be dumped directly into the soil or contaminate the soil through water runoff.
Water pollution is a major problem in India, where many cities dump untreated sewage into the sacred Ganges River. The Ganges is also a major water source for many people, as well as a place to bathe. This leads to thousands of deaths each day from preventable diseases like cholera. But India is not alone; untreated sewage runoff is a major water pollution problem in all parts of the world. Leaks, spills, and dumping of industrial chemicals into rivers also contribute greatly to water pollution. However, even in rich countries, industrial chemicals like chloride and arsenic can leech into groundwater and cause water pollution. Water pollution causes intestinal diseases and disorders.
While slightly more rare, radioactive pollution is another type of pollution threatening ecosystems around the world. In radioactive pollution, radioactive elements leak into the environment from uranium mining, nuclear power plants and other industries that use radioactive materials. You may think of nuclear power plant disasters like the Chernobyl disaster in 1986, but radioactive pollution doesn’t have to come from major nuclear power plant meltdown. Improper dumping of radioactive waste in landfills and other areas can let radioactive chemicals leech into soil and groundwater. The mining of uranium can also create radioactive pollution if industrial safety standards are not met. Radioactive pollution can pollute air, water, or soil, contributing to those types of pollution problems as well. Lethal doses of radioactive elements can lead to death in hours or days, but low doses can also lead to nausea, vomiting, changes in blood chemistry, or genetic mutations.
