The lead can enter the human body through three routes: Digestive tract, respiratory tract, skin. Then, where does plumbous pollution come from?
First of all, the car exhaust is the oldest arch-criminal of plumbous pollution. With the improvement of the living standards of the people of our country, the car has already entered into common people's home now. But the following plumbous pollution of car exhaust can't be ignored. The lead that the exhaust discharges is distributed in the atmosphere and soil extensively. So, chances of people's contact stain are the most.
Secondly, come from family's fitting up. The leaded quantity of pigment, paint of whitewashing wall and furniture is very great. In articles such as the running water pipe of the casting iron, pvc water pipe,etc., all contain the lead at various degrees.
Have some improve looks even relatively high lead content under cosmetics that brighten. Women relying on the fair complexion cream to improve looks, the longer the time when is used is, the blacker the skin on the face is, it is just due to the fair complexion cream, such vicious circle is more harmful.

Especially milk, its protein included can combine with the internal lead into a insoluble compound, enable the human body reduce to plumbous absorbing greatly. Vitamin C can form with the lead the ascorbic impractical lead salt with lower solubility in the intestine, discharge with the excrement and urine outside the body, thus reduce the absorption in the intestine of lead.
Particularly, eat more acid food, the fish, meat, egg, birds and vegetables, fruit enriched with vitamin C; Rape, cabbage, bitter gourd, kiwi fruit, date,etc. can be promoted and arranged the lead. Eat more rich food containing calcium such as milk products, eat more rich food containing iron such as red meat, black sesame, eat more rich food containing zinc such as meat, marine product, nut, coarse food grain.
