Description:Advancements in the use of passive sampling devices (PSDs) for environmental monitoring of contaminants has led to suggestions that PSDs could be used to replace traditional biomonitoring approaches such as sentinel organisms (e.g., mussels). PSDs offer a number of advantages over the use of organisms for aquatic biomonitoring, including the ability to measure contaminants in impaired environments that would be stressful to aquatic biota, and the known relationship between hydrophobic contaminant levels in PSDs and aquatic organisms. Though relationships between hydrophobic legacy contaminants measured using PSDs and mussels have been well studied, there is a lack of information comparing levels of hydrophilic contaminants of emerging concern (CECs) in PSDs and sentinel organisms. Consequently, the present study aimed to utilize data from several place-based assessments in the Great Lakes where PSDs (Polar Organic Chemical Integrative Samplers [POCIS] and Semi Permeable Membrane Devices [SPMDs]) and dreissenid mussels were co-deployed to compare the occurrence and concentrations of a suite of CECs and polycyclic aromatic hydrocarbons (PAHs) in PSDs and mussels.
