Understanding the Ecological Consequences of Ubiquitous Contaminants of Emerging Concern in the Laurentian Great Lakes Watershed: A Continuum of Evidence from the Laboratory to the Environment

摘要: Contaminants of emerging concern (CECs) represent a plethora chemicals only recently recognized as potentially causing harm at environmental concentrations to organisms through diverse modes action. Studies have confirmed CECs are pervasive in water, sediment, and fish tissues collected from the Great Lakes watershed, corroborating studies ecosystems worldwide. In some tributaries, exceed water-quality benchmarks or screening values expected cause adverse effects based on data single-compound exposures. However, scarcity precludes predictions about long-term exposures resident complex mixture CECs. We combine literature review with recent case explore evidence for gathered across continuum field controlled laboratory investigations. This information is used identify obstacles development natural resource management practices. Ranking prominent among these dearth analytical capabilities, paucity studies, complexity integrating CEC additional stressors. Despite knowledge gaps, using existing developing can provide limited directions identifying sources need mitigation. Natural managers encouraged presence when assessing conservation efforts tributaries.
