Metal contaminants of emerging concern in aquatic systems

چکیده
Environmental context There is potential for a range of metals being used in emerging industries to pose risk if they reach aquatic environments. This assessed by evaluating known environmental concentrations against available toxicity data. In most instances risks are low with current usage. Areas identified where additional data needed. Abstract The and technology-critical comprising platinum group rare earth elements, together gallium, germanium, indium, lithium, niobium, rhenium, tantalum, tellurium thallium, have been reviewed determine whether ecosystem health. reasonable body most, but the quality quite variable, more required. Chronic EC10 or NOEC values generally mg L–1 range, far higher than ng meaning that existing health extremely low. Missing reliable niobium while confounding results lanthanum need be resolved. likelihood currently these elements will increase future years. Whether bioavailable forms remains reliably determined. For measured speciation information scarce, unfortunately thermodynamic required calculate their incomplete. addition this problem uncertain some metals, notably those present oxidation states III higher, there also explore links between bioavailability valence metals. circumneutral solutions, calculated free metal ion tend very under such conditions link unclear.

Contaminants of Emerging Concern
Contaminants of emerging concern, or CECs, can be broadly defined as chemicals that have been recently detected in the environment and that may pose public health or ecological risks. CECs encompass a wide variety of chemicals, including pharmaceuticals and household chemicals. Many CECs differ from conventional environmental contaminants such as pesticides, metals, polychlorinated biphenyls (P...

متن کاملA tiered, integrated biological and chemical monitoring framework for contaminants of emerging concern in aquatic ecosystems.
The chemical-specific risk-based paradigm that informs monitoring and assessment of environmental contaminants does not apply well to the many thousands of new chemicals that are being introduced into ambient receiving waters. We propose a tiered framework that incorporates bioanalytical screening tools and diagnostic nontargeted chemical analysis to more effectively monitor for contaminants of...

Contaminants of emerging concern in a large temperate estuary.
This study was designed to assess the occurrence and concentrations of a broad range of contaminants of emerging concern (CECs) from three local estuaries within a large estuarine ecosystem. In addition to effluent from two wastewater treatment plants (WWTP), we sampled water and whole-body juvenile Chinook salmon (Oncorhynchus tshawytscha) and Pacific staghorn sculpin (Leptocottus armatus) in ...
