Water treatment equipment will take care of harmful substances for you

Selenium is one of the essential elements of the human body, but selenium compounds are toxic to humans and animals, (water treatment equipment) has obvious accumulation in the body, which can cause acute and chronic poisoning. In addition to geological factors, selenium in water mainly comes from industrial wastewater pollution. Excessive intake of selenium by humans and animals can cause selenium poisoning. The clinical manifestations of human endemic selenium poisoning are loss of appetite, weakness of limbs, itchy scalp cancer, mangy skin, patchy teeth, hair and nail loss, etc. The selenium poisoning of livestock is manifested as loss of appetite, hair loss, hoof removal, jaundice, anemia, etc. After eating high-selenium plants, it can be fatal in a short time.

Endemic selenium poisoning is mostly due to the high selenium content in the soil, resulting in excessive selenium accumulation in local food crops, vegetables, and poultry. (Water treatment equipment) For example, the selenium content in corn in a certain selenium poisoning area in China is more than 40mg/kg. In general areas, some foods contain a certain amount of selenium. Seafood and animal foods contain higher selenium. For example, pig kidney contains selenium 417mg/kg and flour contains selenium 0.53mg/kg. According to a survey in a staff canteen, the amount of selenium ingested from the diet per person per day in animal experiments showed that: during the 68-day experimental period, the total amount of selenium (sodium selenite-selenium) ingested by rats per week There is no significant difference between 1.5 mg and 0.116 mg in the control group, but there is accumulation of selenium in the liver, and when the content is 0.01 mgkg higher than the control group, the animal's body weight, blood clotting time, white blood cell count, hemoglobin content, serum glutathione aminotransferase activity, etc. The indicators and the toxicity of selenium, and taking into account the possible intake of selenium from food, set the content in drinking water not to exceed
