Background
The harm of heavy metals to human body is common: mercury: after being eaten, the food can directly sink into the liver, and has great damage to the brain and the optic nerve. The natural water containing 0.1 ml per liter of water will be strongly poisoned. Drinking water containing trace mercury can cause accumulative poisoning after long-term consumption; chromium: numbness of limbs and mental disorder can be caused; cadmium: causing hypertension and cardiovascular and cerebrovascular diseases; destruction of bone calcium, causing renal dysfunction; lead: is one of heavy metal pollution with high toxicity, and is difficult to be eliminated once entering human bodies. Directly injure brain cells of human, especially neural plate of fetus, and can cause congenital cerebral sulcus to return to shallow, mental retardation; causing dementia, brain death, etc. in the elderly; cobalt: radioactive damage to the skin; vanadium: injure the heart and lung of human body, resulting in abnormal cholesterol metabolism. Antimony: the silver handornamentals can be turned into brick red with arsenic, and the skin is strongly damaged; thallium: can cause multiple neuritis; manganese: excessive amount can cause hyperthyroidism; tin: lead is an important component in ancient acute toxicity medicine a legendary poisonous bird, whose feathers can turn wine into poison', and is solidified into blocks after entering the abdomen, so that people can die; zinc: excessive zinc poisoning can be caused; any one of these heavy metals can cause headache, dizziness, insomnia, amnesia, nerve disorder, arthralgia, calculus, and cancer (such as hepatocarcinoma, gastric cancer, intestinal cancer, bladder cancer, breast cancer, prostatic cancer, foot and foot diseases and malformation).
At present, due to industrial production pollution and mass use of fertilizers for decades (soil acidification, crops can absorb heavy metals in soil more), the heavy metal content of farmland soil is higher and higher all over the world, and the heavy metal content of agricultural products is higher and higher, so that the health of human beings and animals is directly harmed.
