Recently, awareness of the adverse effects of chemical contaminations is growing as investigations into these pollutants increase and analytical detection techniques improve. The aquatic environment, as an important component of the biosphere, has been termed “the ultimate sink” for natural and man-made chemicals. Given the finite supply of water available, the continued chemical contamination of the aquatic environment may pose a significant environmental health hazard.

We sincerely invite investigators to contribute original research articles as well as review articles that will stimulate the continuing efforts to understand the adverse effects and toxicological mechanisms of chemical contaminants (heavy metals, POPs, and so on) in aquatic environment, including oceans, estuaries, rivers, lakes, streams, and ponds. The special issue will become an international forum for researchers to summarize the most recent developments and ideas in the aquatic environmental health. We are particularly interested in articles about new monitoring techniques and novel molecular mechanisms of aquatic toxicology within the last years.

Potential topics include, but are not limited to:

• Biomonitoring and biomarkers of aquatic environmental health
• Environmental factors and aquatic systems
• Mechanisms of aquatic toxicity
• Cross-species and systems toxicology
