Drinking water is of poor quality, which is very harmful to the body. High-quality drinking water is the basic guarantee for the health of us and our families. So, if we drink substandard water, what harm will it cause to our body?
Organic compounds: carcinogenic and mutagenic
Organic matter pollution and heavy metal pollution have replaced microbial pollution and become the biggest hazard to drinking water safety in my country. According to a research report released by the US Environmental Protection Agency, existing testing techniques have found that there are 756 organic compounds in drinking water, of which 20 are carcinogens, 23 are suspected carcinogens, 18 are carcinogens and 56 are mutagenic.
Excessive heavy metals: accumulation of poisoning
Heavy metals cannot be decomposed in water, and their toxicity is amplified after human consumption, and combined with other toxins in the water to produce more toxic harmful substances. Heavy metals can cause headaches, dizziness, insomnia, joint pain, stones, etc.; especially, it can cause serious damage to the cells, organs, skin, bones, and nerves of the digestive system and urinary system.
Excessive microbes: infection
Drinking water needs to be tested for microbial indicators. Escherichia coli, heat-resistant coliforms, Giardia and Cryptosporidium are all included in the monitoring list; if these indicators are unqualified, bacterial infections and parasitic diseases are likely to occur. Causes people to have gastrointestinal symptoms such as abdominal pain and diarrhea.
Nitrite: poisoning and carcinogenic
The current national standard requires less than 0.1 mg per liter of nitrite, while the standard of the International Codex Alimentarius Commission for natural mineral water is less than 0.02 mg, which is more stringent. Ingestion of trace amounts of nitrite can lead to hypoxia and poisoning, coma or even death in the mild and severe cases. Long-term ingestion of trace amounts of nitrite will increase the risk of cancer in the human body.
