Remove source of lead – 
Since toys are an important part in a child’s life, these cannot be kept away from the children

Avoid foods that are cooked or stored in glazed pottery

Avoid canned food

Wash fruits and vegetable before eating them
Diet - “A diet rich in calcium, iron and vitamin C is important as it does not allow lead to be absorbed in the body and prevents the child from developing anemia. Canned food should be avoided. Fruits and vegetables need to be washed properly before cooking as we do not know whether the fruits and vegetables were grown in lead contaminated soil or not. Again, food should not be cooked in glazed pottery. Kids should be taught not to mouth the toys. And hands should be properly washed before eating,” says renowned pediatrician from Vizag, Dr. Rajni Mukherjee of Seven Hills Hospital.
The key is to eat a balanced, nutritious diet as this diet tends to absorb less lead.
Chelation Therapy – If lead levels are high this is recommended as this process lowers the amount of lead stored in the body.
Chelating agents bind to lead then they are eliminated from the body through urine.

Calcium disodium ethylene diamine tetraacetic acid (CaNa 2EDTA) is a commonly used chelating agent however it is associated with redistribution of lead to the brain

Meso 2, 3-dimercaptosuccinic acid (DMSA) contains two sulphydryl groups and is an effective chelator of lead, that reduces blood lead levels
