Chemical Pollution

The issue that makes it difficult for people and all other living things to survive is environmental pollution. It leads to the deterioration of environmental elements such as soil, water, and air, which upsets the equilibrium of the ecosystem. It has detrimental effects on all living things, including the spread of illnesses through the air and water owing to air and water pollution, among other things. Because of air pollution, which raises the earth's average temperature, there is also an increase in the quantity of carbon dioxide in the atmosphere. It directly affects every living thing.

To eradicate rats, insects, and other pests, various pesticides are used. Different quantities of toxicity are present in them. They eliminate not just the dangerous insects but also the beneficial ones. It throws the local ecology out of balance. Dichlorodiphenyltrichloroethane (DDT) powder usage pollutes the environment both physically and biologically. The contaminated water has a negative impact on both aquatic and terrestrial creatures. It has an impact on the creatures' reproductive systems as well. It also results in other respiratory ailments. Fish and bird development and reproductive capacities are also impacted. Fewer eggs are laid by birds, and not all of them will hatch. Similar to this, some of the fertilized eggs will not develop into newborns because their shells will break and become extremely thin. Pesticides such as dieldrin, aldrin, methoxychloride, benzene hexachloride (BHC), etc. also have comparable effects on the organisms.

Various pesticides, such as dieldrin, aldrin, BHC, and DDT, are employed in agriculture as part of modernization efforts. In a similar vein, overuse of chemical fertilizers is also occurring. When these pesticides and fertilizers mix with rainfall, they find their way to water sources and disrupt the local environment. Fish are destroyed as a result.

Pesticides are necessary to kill and control the many dangerous pests that ruin agricultural crops. They contaminate soil even as they shield agricultural items from dangerous pests. Chemicals like herbicides, insecticides, and fungicides are considered to be one of the primary causes of pollution. Substances like DDT, aldrin, dieldrin, and compounds similar to parathion deteriorate the quality of soil.

The careless use and disposal of industrial chemicals, such as those used in cement, ceramics, glass, plastic, fiber, chemical fertilizers, soap, and detergent, has lowered the standard of several environmental elements, including the air, water, and soil, leading to ecological imbalances. Thus, it's important to utilize and control this kind of pollution appropriately. They shouldn't be dumped right into agricultural land or water supplies.

Let's know

Insecticides such as Aldrin, Dieldrin, DDT, BHC, Chlordane, Lindane, Endosulfan, and so on are prohibited in Nepal. In Nepal, there are restrictions on the manufacture, purchase, sale, import, and export of dichlorvos pesticide.

Methods to Control Chemical Pollution

The following actions may be taken to ensure that industrial chemicals such as soap, detergents, insecticides, glass, ceramics, fiber, plastic, and cement are managed properly.

• It is best to manage glass, ceramics, plastic, and fiber fragments in designated areas rather than tossing them carelessly.
• To prevent dust blows, cement sacs need to be securely secured and covered.
• Instead of using artificial fertilizers, use compost or organic fertilizer.
• Only use chemical pesticides and fertilizers in accordance with a professional's agricultural advice.
• Instead of being combined with water sources or agricultural land after using soap and detergent, waste water should be collected in other locations.
