“…However, in the receiving water of the Östrand mill, an elevated content of HCB (3 µg/kg w.w.) was measured, which can be linked to previous operations at a chlor-alkali plant. Compared to other studies from HCB-contaminated areas outside chlor-alkali plants, the levels were not remarkably high (Hinck et al 2009 ; Huertas et al 2016 ).…”

Sediments polluted by historical emissions from anthropogenic point sources are common in industrialized parts of the world and pose a potential threat to the function of aquatic ecosystems. Gradient studies using fish as a bioindicator are an option to assess the ecological impact of locally polluted areas. This study investigates the remaining effects of historical emissions on sediments outside ten Swedish pulp and paper mills using perch (Perca fluviatilis). The aim has been to obtain a general picture of the impact area of local deposits of cellulose fiber-rich sediments containing elevated levels of trace metals, e.g., Hg, and organochlorines, e.g., dioxins. In addition to analyzing contaminant levels in muscle and liver tissue, morphological measures in the fish that constitute biomarkers for health and reproductivity were measured. Another aim was to augment existing historical data sets to observe possible signs of environmental recovery. Overall, the results indicate only a minor elevation in contaminant levels and a minor impact on the fish health status in the polluted areas, which in several cases is an improvement from historical conditions. However, exceptions exist. Differences in the ecosystems' responses to pollution loads are primarily explained by abiotic factors such as water turnover rate, bottom dynamic conditions, and water chemistry. Weaknesses in the sampling methodology and processing of data were identified. After minor modifications, the applied survey strategy has the potential to be a management tool for decision-makers working on the remediation of contaminated areas.

“…A common type of biomonitoring focused on the food chain is measuring bioaccumulation, in which organisms are deployed in or collected from the remediated system and tissue concentrations of the target contaminants are used as a metric of remedial effectiveness (Lazorchak et al, 2003;Wang, 2016). Biomonitoring has been used widely at Superfund sites, including the Industri-Plex and Wells G&H (Massachusetts), New Bedford Harbor (Massachusetts), Brunswick (Georgia), McIntosh Plant (Alabama), Lower Duwamish Waterway (Washington), Manistique River (Michigan), Palos Verdes Shelf (California), and Midnite Mine (Washington) sites, using a range of organisms, such as trees, mussels, spiders, turtles, fishes, and seabirds (Bergen et al, 1993(Bergen et al, , 2005Blanvillain et al, 2007;Clatterbuck et al, 2018;Flett et al, 2021;Gawel & Hemond, 2004;Hinck et al, 2009;Kelley et al, 2011;Kraus et al, 2017;Nelson & Bergen, 2012).…”

Biomonitoring at contaminated sites undergoing cleanup, including Superfund sites, often uses bioaccumulation of anthropogenic contaminants by field-deployed organisms as a metric of remedial effectiveness. Bioaccumulation studies are unable to assess the equilibrium status of the organisms relative to the contaminants to which they are exposed. Establishing equilibrium provides a reproducible benchmark on which scientific and management decisions can be based (e.g., comparison with human dietary consumption criteria). Unlike bioaccumulating organisms, passive samplers can be assessed for their equilibrium status. In our study, over a 3-year period, we compared the bioaccumulation of selected polychlorinated biphenyls (PCBs) by mussels in water column deployments at the New Bedford Harbor Superfund site (New Bedford, MA, USA) to codeployed passive samplers. Based on comparisons to the calculated passive sampler equilibrium concentrations, the mussels were not at equilibrium, and the subsequent analysis focused on evaluating approaches for estimating equilibrium bioaccumulation. In addition, a limited evaluation of metal bioaccumulation by the exposed mussels and a metal passive sampler was performed. In general, mussel and passive sampler accumulation of PCBs was significantly correlated; however, surprisingly, agreement on the magnitude of accumulation was optimal when bioaccumulation and passive sampler uptake were not corrected for nonequilibrium conditions. A subsequent comparison of four approaches for estimating equilibrium mussel bioaccumulation using octanol-water partition coefficients (K OW ), triolein-water partition coefficients (K TW ), and two types of polymer-lipid partition coefficients demonstrated that field-deployed mussels were not at equilibrium with many PCBs. A range of estimated equilibrium mussel bioaccumulation concentrations were calculated, with the magnitude of the K OW -based values being the smallest and the polymer-lipid partition coefficient-based values being the largest. These analyses are intended to assist environmental scientists and managers to interpret field deployment data when transitioning from biomonitoring to passive sampling.
