‘Through meal, breathing and contact with the skin, heavy metals can enter the body and affect the liver,’ he said.
He said that all the heavy metals were found in food items. Human body could tolerate a level of the heavy metals but excessive amount infected the liver and caused death of a huge number of people annually.
Quoting study report he said that number of liver patient was increasing gradually as 10-12 per cent of total patients admitted to hospitals were liver patients and liver infection became 3rd most common cause of death.
‘Heavy metal is indirectly responsible for the increase in liver patients,’ he said.

Not only for heavy metals but also for food habit, lack of exercise and diabetic attack were behind the spiralling number of liver patients in Bangladesh as well as the Indian subcontinent.
Insecticides in crop fields also have a role to play in spreading of heavy metal in the food chain, he said.
