Industrial discharge contains a large number of hazardous chemicals. It discharges these chemicals directly into the rivers, lakes, or nearby water bodies. These highly toxic chemicals may harm aquatic animals and human beings. Many factories also use freshwater to carry away their waste into the water bodies.
Domestic households, industrial and agricultural practices produce wastewater that can cause pollution of many lakes and rivers. Sewage is the term used for wastewater that often contains faeces, urine and laundry waste.
Radioactive elements are naturally found in the earth's crust. Uranium, thorium and actinium are three NORM (Naturally Occurring Radioactive Materials) series that contaminate water resources. A small amount of radiation is found in all types of water but the extended amount of radiation is harmful to human health.
Diseases, Medical Problems
Water pollutants may cause disease or act as poisons. Bacteria and parasites in poorly treated sewage may enter drinking water supplies and cause digestive problems such as cholera and diarrhea.
Plastic items typically have a very short lifespan — think carrier bags, water bottles, straws, and food containers. And because they're so cheap to make, we don't value them enough to hang on to individual items. Not only that, but the disposal of plastic is often mismanaged — so again, it ends up in landfills.
The use of water by industries, both in the United States and throughout the world, represents a significant portion of total water use. U.S. industrial water use is estimated to be more than 18.2 billion gallons per day (from direct water withdrawals, not including water use from public water supply)1.
This could lead to inundation of sewage works and potential flooding of homes, roads and open spaces. For this reason, the system is designed to overflow occasionally and discharge excess wastewater into the sea and rivers. This practice is known as combined sewer overflows (CSOs) and is permitted.
How can sewage affect my health Sewage and wastewater contain bacteria, fungi, parasites, and viruses that can cause intestinal, lung, and other infections. Bacteria may cause diarrhea, fever, cramps, and sometimes vomiting, headache, weakness, or loss of appetite.
Different doses of radiation cause different health effects. Drinking water that has radionuclides in it puts you in contact with very low doses of radiation every day. You have a higher risk of getting cancer if you drink water with radionuclides in it every day for many years.

Water pollution refers to the contamination of water by the addition of certain harmful substances in a quantity which is way beyond the safety standards. This contamination of water leads to various problems for human beings, aquatic life and flora and fauna of the affected area.
Toxic air pollutants (TAPs) are those pollutants that are known or suspected to cause cancer or other serious health effects, such as reproductive effects or birth defects, or to cause adverse environmental effects.
The ban is part of its efforts to clean its environment and improve quality of life. Now other countries in Asia are increasing their plastic waste imports, raising environmental concerns about their ability to handle such large volumes of recyclables.
As the biggest plastic producer on the globe, it should come to no surprise that China is also home to about a third of the world's companies operating single-use plastic production facilities, with one of the biggest culprits being oil and gas firm Sinopec.
Countries with the highest water waste:
China: 362 trillion gallons/year. United States: 216 trillion gallons/year. Brazil: 95 trillion gallons/year.
A full bath uses up to 80 litres of water whereas a five minute power shower uses about 75 litres. So, provided you don't take too long under the shower, water can still be saved. Remember to turn off the tap while you are actually brushing your teeth. A running tap uses 6 litres of water per minute.
1. Taking the wastewater away. Whenever you flush the toilet or empty the sink, the wastewater goes down the drain and into a pipe, which takes it to a larger sewer pipe under the road. The sewer then joins our network of other sewers and takes the wastewater to a sewage treatment works.
Though little talked about, our species has a monumental problem disposing of its human waste. A recent modeling study finds that wastewater adds around 6.2 million tons of nitrogen to coastal waters worldwide per year, contributing significantly to harmful algal blooms, eutrophication and ocean dead zones.
The Dangers of Hydrogen Sulfide, AKA “Sewer Gas”
A naturally occurring gas, hydrogen sulfide, or “H2S,” is toxic at high concentrations. Prolonged or acute exposure to the gas can cause eye irritation, headache, nausea fatigue, and – in extreme cases – death.
Sewage and wastewater contain bacteria, fungi, parasites, and viruses that can cause intestinal, lung, and other infections. Bacteria may cause diarrhea, fever, cramps, and sometimes vomiting, headache, weakness, or loss of appetite.
Boiling tap water does not get rid of radioactive material.
You should have bottled water in your emergency supplies. You can drink water, juices, or other drinks in sealed containers. Drinks in your refrigerator or freezer are also safe to drink. The package protects the liquid inside from radioactive material.
History. Subsurface water was especially affected by radioactivity in the 30-km zone of evacuation (so called “exclusion zone”), surrounding the Chernobyl Nuclear Power Plant, or CNPP (Kovar&Herbert, 1998. The major and most hazardous contaminant from the perspective of hydrological spread was Strontium-90.
The Fukushima event has been rated 7 on the International Nuclear and Radiological Event Scale, the same level as the 1986 Chernobyl accident. Even so, Japanese authorities estimate that radiation released at Fukushima is only 10 percent of the amount released from the Ukrainian plant.
The radiation in Hiroshima and Nagasaki today is on a par with the extremely low levels of background radiation (natural radioactivity) present anywhere on Earth. It has no effect on human bodies.
Pollution Paragraph in English: 150 Words
Pollution is broadly of four types – air pollution, water pollution, soil pollution and noise pollution. All kinds of pollution are the results of rapid industrialization and urbanization. The poisonous gases such as carbon dioxide, carbon monoxide, CFC, Sulfur dioxide etc.
