Evaluate the effects of following pollutants on environment and human health: Non-biodegradable insecticides Pollen grain Chemical fertilizers containing phosphate and nitrate Wastes containing pathogens originated from health centres Chloroflorocarbon

Environmental pollution may be defined as any undesirable change in the physical, chemical or biological characteristics environment which can cause undesirable effects on various forms of life or property. Types of pollutants i.e. Biodegradable pollutants: That degrades or decomposes rapidly by natural processes. Non-biodegradable pollutants: Do not decompose or decompose very slowly in the environment. Effect of Non-biodegradable insecticides on environment and human health: Pesticides are chemical compositions employed to eliminate fungal or animal pests. They get to be suspended in the air and move when the wind blows, it potentially pollutes the air. When pesticides get into the water, they do so by drifting, running off, and leaching in the soil or through the direct application on top of the water, for example, to eliminate mosquitoes. Effect of pollen on environment and human health: Pollen grains are minute bodies in the form of fine to coarse dust that causes allergic reactions. Effect of Chemical fertilizers containing phosphate and nitrate on environment and human health: Fertilizers containing nitrogen and phosphorus are particularly noxious to animal and human health, causing eutrophication and mass death of fish and other aerobic organisms living in water. Effect of Wastes containing pathogens originated from health centres on environment and human health: Infectious waste may contain any of a great variety of pathogenic microorganisms. Pathogens in infectious waste may enter the human body by a number of routes. Effect of Chloroflorocarbon on environment and human health: Man-made compounds such as chlorofluorocarbons (CFCs), hydrofluorocarbons (HCFCs) and halons destroy ozone in the upper atmosphere (stratosphere).
