Water polluted by parasites, viruses or other pathogenic bacteria will cause many infectious diseases and parasitic diseases.
Water polluted by heavy metals is harmful to human health. Water and food polluted by cadmium will cause kidney and bone diseases after people eat it. Ingestion of 20 mg of cadmium sulfate can cause death. Lead poisoning can lead to anemia and insanity. Hexavalent chromium is very toxic, which can cause skin ulcers and cancer. Drinking arsenic-containing water can cause acute or chronic poisoning. Arsenic inhibits or deactivates many enzymes, leading to metabolic disorders, skin keratinization and skin cancer. Organophosphorus pesticides can cause neurotoxicity, while organochlorine pesticides can accumulate in fat, which is harmful to endocrine, immune and reproductive functions of human beings and animals. Most polycyclic aromatic hydrocarbons are carcinogenic. Cyanide is also a highly toxic substance. After entering the blood, it combines with the pigment oxidase of cells, which interrupts breathing and causes respiratory failure, suffocation and death.
80% of the diseases in the world are related to water. Typhoid fever, cholera, gastroenteritis, dysentery and infectious hepatitis are the five major diseases of human beings, all of which are caused by unclean water.
It must be said that in order to improve the quality of life, we should take a series of measures to protect the water we drink. However, the most effective measure at present is to install the water purifier directly.
