Question

Define pollution and pollutants.

Answer 1

Hint:-Hint: Pollution is the introduction into the ecosystem of hazardous products.
Pollutants are called these hazardous materials.

Complete step-by-step solution:-
Pollution is the introduction into the natural world of pollutants that cause adverse changes. Pollution, such as noise , heat, or light, may take the form of chemical substances or electricity.
A pollutant is a waste material which pollutes air, water , or soil. Three factors decide the extent of a pollutant: its chemical structure, concentration, the area affected and persistence.
A global problem is contamination. While urban areas are usually more contaminated than rural areas, pollutants may spread to remote locations where there are no people. Pesticides and other chemicals have been found in the Antarctic ice sheet, for example. In the middle of the northern Pacific Ocean, a huge aggregation of microscopic plastic particles forms what is known as the Great Pacific Garbage Patch.
Ocean contaminants are carried far and wide by ocean currents and moving fish. Air and water currents bring waste. Winds can pick up radioactive material unintentionally emitted from a nuclear reactor and disperse it around the world. Smoke from a factory in one country drifts into another country.
Air pollution , water pollution, and land pollution are the three main forms of pollution.
Polluted air can be harmful, even though the contaminants are invisible. It can make people's eyes flame and make them have trouble breathing. Also, it may raise the risk of lung cancer. Natural disasters can also cause increasingly increasing air pollution. They expel volcanic ash and gases into the atmosphere as volcanoes erupt. Other common pollutants, including nitrogen oxide, sulphur dioxide, and hydrocarbons, are emitted by vehicles and factories. Greenhouse gases are another cause of air pollution. In the atmosphere, greenhouse gases such as carbon dioxide and methane exist naturally.
Human activities, such as burning fossil fuels and damaging forests, have increased the number of greenhouse gases in the atmosphere. This has been exacerbated by the greenhouse effect, and average temperatures are rising around the world.
Polluted water is unhealthy for drinking and for bathing. The majority of people drinking contaminated water are exposed to dangerous substances that can make them ill years later. Others consume bacteria and other tiny marine organisms that cause sickness.
There are some natural sources of water pollution. For instance, oil and natural gas may leak from natural underwater sources into the oceans and lakes. Human activity leads to the waste of water as well. Factory products and oils are often spilled into rivers or seep into them. Mining and fracking will lead to water contamination as well. Buried chemical waste will pollute the supply of water, too. A widespread cause of water contamination is sewage that has not been treated properly. Fertilizer used in agriculture is another significant cause of water contamination. Garbage fouls the ocean too. Many bottles of plastic and other bits of garbage from vessels are thrown overboard.
Many of the same contaminants which foul the water also affect the ground. Sometimes, mining leaves the soil polluted with toxic chemicals. The breeze sweeps out pesticides and fertilisers from farm fields. Plants, livestock, and even persons may be affected by them. Trash is another way of polluting the ground. Dangerous contaminants such as oils, additives, and dye are also found in trash. Such toxins can leach into the soil, destroying plants, livestock, and humans. Inefficient systems for collecting waste lead to soil emissions.
Pollution control:
The amount of waste that winds up in landfills, incinerators, and rivers is minimised by recycling.
Governments will counter emissions by passing laws that regulate the number and types of chemical factories and agribusinesses that are allowed to use.

Note:- Pollution is the earth's toxin. This environment can be polluted by all sorts of things performed directly or indirectly by humans. It is not feasible to regulate emissions entirely, but we have to find solutions to reduce it.
