Chemical and radioactive substances can cause cancer and as well as birth defects. Environment Pollution has been found to be present widely in the environment. There are a number of effects of this: Sulphur dioxide and nitrogen oxides can cause acid rain which lowers the ph value of soil.

Report: Air pollution a leading environmental cause of cancer

Water pollution causes approximately 14,000 deaths per day, mostly due to contamination of drinking water by park untreated sewage in developing countries. An estimated 700 million Indians have no access to a proper toilet, and 1,000 Indian children die of diarrhoeal sickness every day. 26 nearly 500 million Chinese lack access to safe drinking water. 27 656,000 people die prematurely each year in China because of air pollution.

Larger scale and environmental damage is ilahi not uncommon when coastal oil rigs or refineries are involved. Some sources of pollution, such as nuclear power plants or oil tankers, can produce widespread and potentially hazardous releases when accidents occur. In the case of noise pollution the dominant source class is the motor vehicle, producing about ninety percent of all unwanted noise worldwide.

Humans have ways to cut greenhouse gas emissions and avoid the consequences of global warming, a major climate report concluded. But in order to change the climate, the transition from fossil fuels like coal and oil needs to occur within decades, according to the final report this year from the un's Intergovernmental Panel on Climate Change (ipcc). 21 Some of the more common soil contaminants are chlorinated hydrocarbons (cfh heavy metals (such as chromium, cadmium -found in rechargeable batteries, and lead -found in lead paint, aviation fuel and still in some countries, gasoline mtbe, zinc, arsenic and benzene.

Forms of pollution The major forms of pollution are listed below along with the particular pollutants relevant to each of them: Water pollution, by the release of waste products and contaminants into surface runoff into river drainage systems, leaching into groundwater, liquid spills, wastewater discharges. Soil contamination occurs when chemicals are released by spill or underground leakage. Among the most significant soil contaminants are hydrocarbons, heavy metals, mtbe, 8 herbicides, pesticides and chlorinated hydrocarbons. Littering Radioactive contamination, resulting from 20th century activities in atomic physics, such as nuclear power generation and nuclear weapons research, manufacture and deployment.

(see alpha emitters and actinides in the environment.) noise pollution, which encompasses roadway noise, aircraft noise, industrial noise as well as high-intensity sonar.

Nuclear weapons continued to be tested in the cold War, sometimes near inhabited areas, especially in the earlier stages of their development. The toll on the worst-affected populations and the growth since then in understanding about the critical threat to human health posed by radioactivity has also been a prohibitive complication associated with nuclear power. Though extreme care is practiced in that industry, the potential for disaster suggested by incidents such as those at Three mile Island and Chernobyl pose a lingering specter of public mistrust. One legacy of nuclear testing before most forms were banned has been significantly raised levels of background radiation. International catastrophes such as the wreck of the Amoco cadiz oil tanker off the coast of Brittany in 1978 and the Bhopal disaster in 1984 have demonstrated the universality of such events and the scale on which efforts to address them needed to engage. The borderless nature of atmosphere and oceans inevitably resulted in the implication of pollution on a planetary level with the issue of global warming.

Air pollution would continue to be a problem in England, especially later during the industrial revolution, and extending into the recent past with the Great Smog of 1952. This same city also recorded one of the earlier extreme cases of water quality problems with the Great Stink on the Thames of 1858, which led to construction of the london sewerage system soon afterward. It was the industrial revolution that gave birth to environmental pollution as we know it today. The emergence of great factories and consumption of immense quantities of coal and other fossil fuels gave rise to unprecedented air pollution and the large volume of industrial chemical discharges added to the growing load of untreated human waste. Chicago and Cincinnati were the first two American cities to enact laws ensuring cleaner air in 1881. Other cities followed around the country until early in the 20th century, when the short lived Office of Air Pollution was created under the department essay of the Interior. Extreme smog events were experienced by the cities of Los Angeles and Donora, pennsylvania in the late 1940s, serving as another public reminder. 7 Modern awareness Pollution became a popular issue after WW2, when the aftermath of atomic warfare and testing made evident the perils of radioactive fallout.
