Harm caused by excessive heavy metals in water

There are many types of heavy metals, and many of them can be seen around us. If the water quality is polluted by heavy metals, the water source may be undrinkable. why? In this chapter, manufacturers of online water quality monitors come to understand the harm caused by some heavy metals in water exceeding the standard! In fact, heavy metals occupy a large proportion of water pollution. Heavy metal pollution is easy to accumulate and expand in the biological chain, and their toxicity is also strong. Here we mainly come to understand the harm caused by the four heavy metals of lead, mercury, cadmium and chromium in water exceeding the standard. 1. Lead. Lead in water mainly comes from the discharge of industrial pollutants and industrial wastewater, as well as the application of pesticides and insecticides in agricultural production, but the main source is the release of lead caused by corrosion of urban tap water pipe networks. Once the lead in the water exceeds the standard, the harm to the human body is certain! Just like adults, if money is poisoned, symptoms such as fatigue, depression, and kidney deficiency will occur. If it is a long-term lead injury, it will cause anemia, nerve damage in the limbs, high blood pressure and other consequences. If it is children and pregnant women, it will cause abnormal behaviors such as inattention, hyperactivity, poor learning ability, and easy anger in children. It can cause miscarriage, premature birth and stillbirth in pregnant women. 2. Mercury is one of the most toxic elements in heavy metal pollution. Both inorganic mercury salts and organic compounds are harmful to the human body, but the hazards of the two are different. Inorganic mercury salts will inhibit the function of cells because of the combination of mercury ions and enzyme proteins to simulate the activity of various enzymes. As for organic mercury compounds, methylmercury is highly toxic, and it will be absorbed and not easily excreted after entering the human body. When accumulated in the body, it will invade the central nervous system, thereby destroying the brain blood vessels, causing numbness of the limbs, language disorders, etc. symptom. 3. Cadmium, unlike lead, lead is an essential element for the human body, but cadmium is not. There is almost no cadmium in the body of a newborn baby, and the cadmium in the human body enters the human body the day after tomorrow due to the external environment. If cadmium poisoning can cause arteriosclerosis, kidney atrophy, nephritis and so on. In addition, cadmium can also replace part of the calcium in the bones, which will cause the bones to loosen and soften, and in severe cases, natural fractures will occur. In addition, it also has carcinogenic and teratogenic substances. 4. Chromium, the same as 3 o’clock“ge”, but they are two different substances, chromium mainly comes from industrial waste water, chemical industry, electroplating and other industrial pollution. It will enter the human body through nitrification, respiratory tract, skin, etc. It will cause vomiting, abdominal pain and other symptoms when it passes through the digestive tract, and it will cause dermatitis and eczema if it passes through the skin. If inhaled for a long time, it may cause cancer. Warm reminder: If you want to know whether the heavy metal content in the water exceeds the standard, the heavy metal detector is a good helper at this time, and the detectors used for different parameters are different, which needs to be determined according to the needs of the user.
