What are the consequences of water pollution?

Hazard 1: Harm to human health. Water pollution directly affects the quality of drinking water sources. When the drinking water source is polluted, the relevant water treatment departments can not solve this pollution well, which will lead to ascites, diarrhea, intestinal nematodes, hepatitis, gastric cancer, liver cancer and other diseases. Contact with unclean water can also lead to skin diseases, trachoma, schistosomiasis, hookworm disease and other diseases. More seriously, water pollution affects the secretion of human sex hormones to a great extent, and affects human reproductive ability to a certain extent; Others point out that water pollution can lead to spontaneous abortion or congenital disability. In short, the harm of water pollution to human health is multifaceted and cannot be ignored. The rise of a large number of water purifier manufacturers around the world is a good proof!

Hazard 2: reduce crop yield and quality.

Because sewage provides a lot of water and fertilizer, farmers in many areas have the habit of irrigating farmland with sewage. However, the painful lesson shows that wastewater containing toxic and harmful substances pollutes farmland soil, causing crops to wither and die, causing huge losses to farmers. Although there are bumper harvests in many areas, there is a crisis of crop pollution behind the bumper harvest. Studies have shown that trace organic matter, including toxic pesticides, can be detected in vegetables or food crops planted in some sewage irrigation areas, which will definitely endanger the health of consumers.

Hazard 3: Affect the output and quality of fishery production.

The output and quality of fishery production are directly related to water quality. It is not an isolated case that large-scale fish deaths are caused by water pollution in freshwater fishing grounds. There are still many fish and aquatic organisms in natural water bodies that are on the verge of extinction or have been extinct. Mariculture is also damaged and threatened by water pollution. Water pollution will not only lead to the death of fish and affect the yield, but also cause the variation of fish and aquatic organisms. In addition, the accumulation of harmful substances in fish and aquatic organisms is found, which greatly reduces their edible value, and eating these fish will also threaten human health.

Hazard 4: Restrict economic development. Many people may not notice the harm of water pollution at this point! The reason is that industry, as the pillar of social economy, needs water as raw material or washing products and directly participates in the processing of products, and the deterioration of water quality will directly affect the quality of products. The consumption of industrial cooling water is the largest, and the deterioration of water quality will also cause blockage, corrosion and scaling of cooling water circulation system, and the increase of water hardness will also affect the life and safety of boilers. This affects the output of industry to a certain extent, and water pollution affects the economic development of the country to a great extent, whether it is for human health or for sideline industries such as agriculture and fisheries!

The above summary of the hazards of water pollution just wants to convey a sense of environmental protection to everyone! In fact, whether it is our health or the impact on the macro-economy, it will eventually affect the survival and development of mankind! If water pollution can be well solved, then the survival and development of human beings will eliminate a huge obstacle!
