113Cd-NMR studies have established that vertebrate and invertebrate metallothioneins contain two unique metal-thiolate clusters. However, it proved to be difficult to account theoretically for all features of the 113Cd-NMR spectra. In a reinvestigation of these features using chromatographically homogeneous 113Cd7-metallothionein we have identified a total of seven 113Cd resonances and have con...
The concentrations of Cu, Pb, and Zn in the crystalline style (CS) and in the remaining soft tissues (ST) of the green-lipped mussel Perna viridis from 10 geographical sites along the coastal waters off peninsular Malaysia were determined. The CS, compared with the remaining ST, accumulated higher levels of Cu in both contaminated and uncontaminated samples, indicating that the style has a high...
Some fish populations inhabiting contaminated environments show evidence of increased chemical tolerance, however the mechanisms contributing to this tolerance, and whether this is heritable, are poorly understood. We investigated the responses of two populations of wild three-spined stickleback (Gasterosteus aculeatus) with different histories of contaminant exposure to an oestrogen and copper...
Background. Pharmaceuticals have become the aquatic pollutants of growing concern. Caffeine is one most widely distributed in surface waters among them. However, environmentally relevant models its effect, which include combined exposures with probable confounding factors, are unknown. Microplastics a suspected vector that influences caffeine bioavailability. The temperature dependence response...
