Презентация на тему по теме Загрязнение воды (10 класс.Английский язык)

Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans and groundwater). This form of environmental degradation occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds.What is water pollution?

Слайд 4 Thermal pollution

Thermal pollution is the rise or fall in the

temperature of a natural body of water caused by human influence.

Elevated water temperatures decrease oxygen levels, which can kill fish and alter food chain composition

Cases of pollution
The main source of pollution is the emission

of chemical compounds from factories

Contaminants may include organic and inorganic substances.

Слайд 6 Water pollution affects the entire biosphere – plants and organisms living

in these bodies of water. In almost all cases the effect is damaging not only to individual species and population, but also to the natural biological communities.

Слайд 7 Point sources

Point source water pollution refers to contaminants that enter a

waterway from a single, identifiable source, such as a pipe or ditch.

Nonpoint source pollution refers to diffuse contamination that does not

originate from a single discrete source.
