What is the main way methylmercury enters the human body?

AInhalation

BSkin contact

CDietary route

DDrinking contaminated water

Answer:

C. Dietary route

Read Explanation:

  • Emissions of mercury to the air from both anthropogenic and natural sources are in inorganic forms that can be converted biologically to methylmercury in soil and water.

  • Methylmercury bioaccumulates and enters the human body readily via the dietary route.

  • Methylmercury is a potent neurotoxic chemical. Unborn children (i.e. fetuses) are the most susceptible population group, the exposure being mainly from fish in the diet of the mother.

  • Methylmercury is also excreted in mothers' milk.
