| Research Abstract |
Methylmercury (MeHg)and persistent organic pollutantspoly (POPs)such as PCBs and DDTs are environmentally persistent neurodevelopmental toxicants. They can be transferred from the mother to the fetus via palacenta and to the infant via breastfeeding. The main sources of the exposures to MeHg and POPs are food, particularly the consumption of fish and fish products in Japan. We previously carried out an animal experiment to examine the effect of co-exposure to MeHg and POPs on mother-to-child kinetics using mice and guinea pig. We administered MeHg and POPs using whale oil for POPs exposure. p, p'-DDE-d8 added was similarly accumulated and, d8 provided a useful index for predicting the distribution of DDTs. We observed negative effects on eye opening and open field test in group of mice of high contaminated POPs oil.
