Physical controls on total and methylmercury concentrations in streams and lakes of the northeastern USA

, : Physical controls on total and methylmercury concentrations in streams and lakes of the northeastern USA. Ecotoxicology 14(1-2): 125-134

The physical factors controlling total mercury (HgT) and methylmercury (MeHg) concentrations in lakes and streams of northeastern USA were assessed in a regional data set containing 693 HgT and 385 corresponding MeHg concentrations in surface waters. Multiple regression models using watershed characteristics and climatic variables explained 38% or less of the variance in HgT and MeHg. Land cover percentages and soil permeability generally provided modest predictive power.

SAM-R/3 and SAM-P/6 as new murine models for senile osteoporosis. Age-related changes of the femoral bone mass in several strains of the senescence-accelerated mouse (SAM) were investigated. Microdensitometrically, all strains exhibited essentially the same patterns of age changes, that is, bone mass corrected b...
