“…What is a contaminant of emerging concern (CEC)? There is no single consensus, definition, or static list of CECs (Diamond and Burton, 2021). A CEC list must be dynamic, as new chemicals are continuously developed, produced, and detected with analytical advancements (Murray and others, 2010).…”

“…Concerns about the health effects of contaminant mixtures together with the impracticality of quantifying thousands of unregulated chemicals are motivating new toxicologic approaches. The goal of these new approaches is to discover which chemicals are of greatest concern (Diamond and Burton, 2021). Scientists in the USGS Ecosystems Mission Area (https://www.usgs.gov/ mission-areas/ecosystems) use exposure-effects-driven tools.…”

This report describes scientific gaps that limit our ability to predict water-quality effects on water availability for beneficial uses across the United States. Water-quality constituents considered in the report include salinity, geogenic constituents, contaminants of emerging concern, and nitrogen. For each constituent, there is a selection of scientific gaps, approaches, and outcomes to help guide portions of the U.S. Geological Survey Water Mission Area (https://www.usgs. gov/mission-areas/water-resources) research portfolio and other national research efforts. Although the report is not comprehensive, and new issues are likely to emerge, it does provide an assessment of many of the major challenges and opportunities concerning water-quality effects on water availability for beneficial uses. Due to the changing nature of water-quality concerns, and to deal with issues not described in this report, it will be important to maintain broad-based expertise and flexibility to address the full spectrum of long-term water-quality issues facing the Nation's water resources.

“…Labeled contaminants of emerging concern (CECs), these chemicals encompass an enormous diversity of structural and functional properties; and perhaps not surprisingly, there is a general lack of understanding of their risks to aquatic ecosystems, including the Great Lakes. Uncertainties surrounding the nature and risks of these contaminants is reflected in the nondescriptive term CECs, which serves as a catch-all for contaminants that are largely unregulated yet have the potential to produce adverse effects (Diamond & Burton, 2021).…”

Assessing the ecological risk of contaminants in the field typically involves consideration of a complex mixture of compounds which may or may not be detected via instrumental analyses. Further, there are insufficient data to predict the potential biological effects of many detected compounds, leading to their being characterized as contaminants of emerging concern (CECs). Over the past several years, advances in chemistry, toxicology, and bioinformatics have resulted in a variety of concepts and tools that can enhance the pragmatic assessment of the ecological risk of CECs. The present Focus article describes a 10+‐ year multiagency effort supported through the U.S. Great Lakes Restoration Initiative to assess the occurrence and implications of CECs in the North American Great Lakes. State‐of‐the‐science methods and models were used to evaluate more than 700 sites in about approximately 200 tributaries across lakes Ontario, Erie, Huron, Michigan, and Superior, sometimes on multiple occasions. Studies featured measurement of up to 500 different target analytes in different environmental matrices, coupled with evaluation of biological effects in resident species, animals from in situ and laboratory exposures, and in vitro systems. Experimental taxa included birds, fish, and a variety of invertebrates, and measured endpoints ranged from molecular to apical responses. Data were integrated and evaluated using a diversity of curated knowledgebases and models with the goal of producing actionable insights for risk assessors and managers charged with evaluating and mitigating the effects of CECs in the Great Lakes. This overview is based on research and data captured in approximately about 90 peer‐reviewed journal articles and reports, including approximately about 30 appearing in a virtual issue comprised of highlighted papers published in Environmental Toxicology and Chemistry or Integrated Environmental Assessment and Management.

Pharmaceuticals and personal care products (PPCPs) are released from multiple anthropogenic sources and thus have a ubiquitous presence in the environment. The environmental exposure and potential effects of PPCPs on biota and humans has aroused concern within the scientific community and the public. Risk assessments are commonly conducted to evaluate the likelihood of chemicals including PPCPs that pose health threats to organisms inhabiting various environmental compartments and humans. Because thousands of PPCPs are currently used, it is impractical to assess the environmental risk of all of them due to data limitations; in addition, new PPCPs are continually being produced. Prioritization approaches, based either on exposure, hazard, or risk, provide a possible means by which those PPCPs that are likely to pose the greatest risk to the environment are identified, thereby enabling more effective allocation of resources in environmental monitoring programs in specific geographical locations and ecotoxicological investigations. In the present review, the importance and current knowledge concerning PPCP occurrence and risk are discussed and priorities for future research are proposed, in terms of PPCP exposure (e.g., optimization of exposure modeling in freshwater ecosystems and more monitoring of PPCPs in the marine environment) or hazard (e.g., differential risk of PPCPs to lower vs. higher trophic level species and risks to human health). Recommended research questions for the next 10 years are also provided, which can be answered by future studies on prioritization of PPCPs. Environ Toxicol Chem 2022;00:1–14. © 2022 SETAC
