A drastic amphibian decline has been observed worldwide, which can be attributed (among other factors) to exposure to pollutants. Considering that cadmium corresponds to the most rapidly increasing trace metal in the environment, the aim of this work was to
Increased anthropogenic emission of CO2 changes the carbonate chemistry and decreases the pH of the ocean. This can affect the speciation and the bioavailability of metals in polluted habitats such as estuaries. However, the effects of acidification on metal accumulation
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

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

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
