In freshwater environments, microbial assemblages attached to submerged substrates play
an essential role in ecosystem processes such as primary production, supported by …

Toxicity of compounds belonging to persistent organic pollutants (POPs) is widely known,
and their re-emission from glaciers has been conclusively demonstrated. However, the …

Aquatic insects provide a critical energy subsidy to riparian food webs, yet their role as
vectors of contaminants to terrestrial ecosystems is poorly understood. We investigated …

Mercury (Hg) is one of the few metals known to accumulate through food webs to
concentrations that are much higher in upper trophic level organisms than those in primary …

To evaluate the biomagnification extent of polybrominated diphenyls ethers (PBDEs) and
polychlorinated biphenyls (PCBs) in a highly contaminated freshwater food web from South …

Urban areas contribute substantially to xenobiotic contaminant loads in rivers, but their
effects have been investigated more for individual organisms and sensitive taxa, rather than …

In past studies, the health and ecological risks of PCBs are well established. The impact of
low-dose PCBs on aquatic ecosystems for an extended period is a matter of concern in the …

The bioaccumulation and biomagnification of sediment-bound hydrophobic organic
contaminants (HOCs) are of major concern for environmental and human health. In dynamic …

The relative contribution of aquatic vs. terrestrial organic matter to the diet of consumers in
fluvial environments and its effects on bioaccumulation of contaminants such as mercury …

Three fish species, mud carp (Cirrhinus molitorella), tilapia (Tilapia nilotica), and
plecostomus (Hypostomus plecostomus), from rivers in the Pearl River Delta (PRD) were …
