Human health risk assessment in relation to environmental pollution of two artificial freshwater lakes in the The Netherlands

Article Abstract:

Recreational activities on two artificial freshwater lakes along the River Meuse in The Netherlands are discussed relative to environmental pollution and human health risk assessment. Levels of contaminants are persistent in sediments although discharges have been reduced in recent decades. The highest intake seems to be associated with consumption of contaminated fish and resulting exposure to lead (Pb) and zinc (Zn). Taking into account concentrations in surface water, risk from consumption of contaminated fish went down by more than two orders of magnitude to negligible. The degree of uncertainty is high for both exposure assessments.

Meeting of the minds on mercury

Article Abstract:

An attempt to reconcile controversial and conflicting scientific data from several studies on the health effects of methylmercury (MeHg), an organic mercury (Hg) form that bioaccumulates in fish and other seafood, is being made at a workshop. No obvious reasons for inconsistences in findings has been identified. Taking the studies as a whole it can be seen that MeHg is a neurodevelopmental neurotoxin. Effects of exposure to low doses are not clear. The EPA has declared that coal-fired power plants must measure the Hg content of coal burned and that smokestack testing will take place.

PCB congener profile in the serum of humans consuming Great Lakes fish

Article Abstract:

Methodologies for establishing a polychlorinated biphenyl congener profile are presented, based on subjects who eat Great Lakes fish and those who do not. These included dual column capillary column gas chromatography of serum samples.
