Cadmium, lead detector.
Background technique
Heavy metal refers to the metal that specific gravity is greater than 5（Refer generally to density greater than 4.5 grams of metals per cubic centimeter）, also refer to
Atomic weight is greater than 55 metal.Source of heavy metal pollution be mainly dig up mine, smelt etc. industrial and mining enterprises discharge exhaust gas, waste water and
The burning of the fossil fuel such as waste residue, coal and petroleum and being excessively used for agriculture chemical, wherein mainly include Hg, Cd, Pb, Cr,
Zn, Cu, Ni and metalloid As etc..The division methods of heavy metal ions in soil form have very much, but stroke more common at present
Dividing method is five point-scores of Tessier, i.e., the heavy metal in soil is divided into ion-exchange state, carbonate combine state, ferrimanganic oxygen
5 kinds of forms such as compound reference state, organic sulfur compound reference state, residual.
Currently, countries in the world soil, there are different degrees of heavy metal pollution, Hg about 1.5 ten thousand is discharged in the whole world every year on average
T, it be 5,000,000 t, Mn be 15,000,000 t, Ni is 1,000,000 t that Cu, which is 3,400,000 t, Pb,.China's regional agriculture environmental degradation and agricultural product by
Heavy metal pollution phenomenon is extremely serious, especially in some developed areas.According to incompletely statistics, China by cadmium, arsenic,
Nearly 20,000,000 hm2 in the arable land of the heavy metal pollutions such as lead, chromium, mercury, accounts for about the 1/5 of total area under cultivation.Moreover, China in recent years
A lot of heavy metal pollution events have occurred.
Mercury：Liver is directly sunk to after eating, and brain, nerve, eyesight is destroyed very big.Containing 0.01 milli in every liter of water of natural water
Gram, it will lead to people's poisoning.Cadmium：Lead to hypertension, causes cardiovascular and cerebrovascular disease；Bone and liver kidney are destroyed, and causes kidney failure.
Lead：It is the biggish one kind of heavy metal pollution Poisoning, once would become hard to exclude into human body, can directly injures the brain cell of people,
The especially nervous system of fetus can cause congenital feeblemindedness.Cobalt：There is radioactive damage to skin.Vanadium：The heart, the lung hurted sb.'s feelings,
Lead to cholesterol metabolism abnormity.Antimony：Silver-colored jewelry can be made to become brick-red with arsenic, have radioactive damage to skin.Thallium：It can make one more
Inflammation nerve.Manganese：Hyperthyroidism is made one when excess, can also injure vitals.Arsenic：It is one of the component of arsenic,
There is severe toxicity, people can be caused dead rapidly.Long Term Contact is a small amount of, will lead to slow poisoning.In addition there are also carcinogenicities.It can be seen that cadmium,
The pollution such as lead is very big to the health hazard of environment and the mankind, therefore, to environment and water quality, especially drinking water, underground water and river
