The Mae Tao watershed, northwest Thailand, has become contaminated with cadmium (Cd) as a result of zinc ore extraction (Padaeng deposit) in the nearby Thanon-Thongchai mountains. Consumption of contaminated rice has led to documented human health impacts. The aim of

PbtA, a putative P(1B)-type ATPase from the Gram-negative soil bacterium Achromobacter xylosoxidans A8 responsible for Pb(2+)/Zn(2+)/Cd(2+)-resistance in Escherichia coli, was heterologously expressed in Saccharomyces cerevisiae. When present in Zn(2+)- and Pb(2+)/Cd(2+)-hypersensitive S. cerevisiae strains CM137 and DTY168, respectively, PbtA was
We studied the bonding and release kinetics of Cd, Cu and Pb from different soils in the older metropolitan area of Copenhagen. Total Cd, Cu and Pb concentrations were elevated 5-27 times in the urban soils compared to an agricultural

This study investigated the effect of ambient Cadmium (Cd) on haemocyte apoptosis of the shrimp, Penaeus monodon. Cellular response was determined in Cd-exposed (0, 0.05, 0.5 and 5 mg L(-1)) shrimp. Results showed that 0.05 mg L(-1) Cd(2+) had no significant effect on the
