Types of environmental pollution
According to Litter, it costs you, there are three main types of environmental pollution:
Pollution water
Water pollution is a change in the negative direction in the water environment. Specifically, in the environment of water will appear foreign substances in the form of liquid or solid. This change makes the water toxic to humans and animals. Full view on water pollution.
Soil pollution
Soil pollution is the presence of xenobiotic substances causing harmful effects on human and animal life. These substances are shaped by industrial activities, agrochemicals, etc. Pollution levels depend on the use of chemicals and industrialization. Full view on soil environment pollution.
Air pollution
Air pollution is the presence of a foreign substance or change in air composition. This makes the air smell unpleasant, not clean, reducing the ability to observe by dust. Full view on air pollution.
Causes of environmental pollution
There are many causes of environmental pollution but perhaps the most impact is due to human activities. In addition, environmental pollution can also occur due to the impact of nature. As follows:
Due to waste from factories and industrial parks
Accordingly, factories and enterprises discharge untreated waste into the environment. Failure to treat wastewater before being discharged into the environment will cause serious pollution of the water environment.
In addition, at factories using fossil fuels as fuel has created CO2, CO, N0x, SO2 ... These emissions also cause serious air pollution, even causing the home effect. glasses.
Due to toxic substances, plant protection chemicals
That is the pesticides, chemical fertilizers excess by people do not use all and throw around, indiscriminately. These wastes will gradually seep into underground water sources, ponds and lakes ... This will not only contaminate soil but also groundwater. Even these toxic substances can be sent to the sea causing the "red tide" phenomenon ...
Due to solid waste
In the process of developing the country, many establishments were born to serve the increasing needs of people. This leads to an increase in solid waste.
The source of solid waste may come from domestic activities, industrial zones or health facilities. These wastes are not treated before being discharged into the environment and accumulated in the environment for a long time. This causes air pollution, water pollution, groundwater pollution, soil pollution. At the same time, it affects the ecosystem and human health.
Due to the dust
It can be said that this is the main cause of air pollution. This situation often occurs in big cities, the density of cars is crowded ...
Shortcomings in the management stage
The pollution occurs, it is indispensable for the authorities. Specifically, the quality and efficiency of environmental technologies are not high.
