Health
risks of toxic metals during fetal life, infancy and childhood
We are exposed to
methylmercury from predatory fish and inorganic mercury from dental amalgam.
There is an association between prenatal exposure to methylmercury in
fish-eating populations and developmental impairment in children. Therefore,
pregnant women in Sweden are recommended to avoid eating predatory fish with
methylmercury contamination. We have recently studied the exposure to
methylmercury in pregnant women with relatively low fish consumption. As we
found a wide range of MeHg levels, we are presently studying the exposure to
methylmercury in women of childbearing age, who consume much fish, In addition,
we are studying exposure to
methylmercury and inorganic mercury (originating from dental amalgam) during
fetal life and via breast milk (up to 3 months). We will also aim
elucidate the possible interactions between mercury and selenium as previous
studies have indicated that selenium may protect against mercury toxicity.
Another research aim is to
increase the understanding of association between low dose lead exposure in
children and neurotoxic effects. In collaboration with Polish researchers and
specialists, we further investigate neurophysiological effects in relation lead
exposure.
