“…The declines since the late 1990s might reflect remediation efforts at several sites in the region through the 1990s. 20 A declining concentration trend for DP was reported previously 9 for Niagara River suspended sediments and confirmed in this study (R = À0.60, p < 0.01), with results consistent with declines observed in a sediment core collected near the river mouth on the Niagara River bar. 21 It is not clear if the decline in DP represent changes in production volumes at the manufacturing site or whether it reflects emission controls adopted over the past 20þ years at the site.…”

Temporal trends and seasonal variation of Dechloranes (Dec) 602, 603, 604, and Chlordene Plus (CP) in Niagara River suspended sediment, a Lake Ontario sediment core, and Lake Ontario lake trout were investigated, with Mirex and Dechlorane Plus (DP) included for comparison. Temporal concentration trends were generally consistent in each of the media for all compounds with the lowest concentrations observed in or after the late 1990s. In Niagara River suspended sediments, all compounds showed seasonal variation over a year with distinct profiles observed. The relative concentration patterns observed were total DP > Mirex > Dec 602 and Dec 604 > Dec 603 > CP in suspended sediments and sediment cores, whereas Mirex was highest in lake trout, followed by Dec 602 and DP. Dec 602 concentrations were 50 to 380 times greater than those of DP in lake trout, indicating Dec 602 has a greater bioaccumulation potential. The estimated biota-sediment accumulation factor (BSAF) for Dec 602 was much greater than for DP in Lake Ontario, and was greater than those calculated for PBDEs, indicating that assessment of some dechlorane compounds is merited if use is ongoing or planned.

“…Cages were placed upstream and downstream of suspected sources and compared against an upstream watershed reference location. Mussel collection, deployment and retrieval methods are as described in [20] with the following exceptions: deployment occurred over 28 days in the trackdown study for comparison to SPMD uptake; composites of 10 -12 mussels (up to 80 g wet tissue) were used for PCB and lipid content analysis. (u/s = upstream, d/s = downstream).…”

Project Trackdown is an investigative environmental program aimed at tracking sources of polychlorinated biphenyl (PCB) contamination in Great Lakes tributaries. The program uses a multimedia weight of evidence approach for identifying sources of PCBs to the environment. PCB concentrations in environmental media (sediment, water, suspended sediment and soil), passive samplers and/or exposed biota (mussels, young-of-the-year fish and benthic invertebrates) are used in combination to evaluate bioavailability and identify local anomalies within a tributary. These lines of evidence can be assessed with simple chemometric techniques and fingerprinting of PCB congener profiles, and, combined with anecdotal information such as land use history and tributary alterations, may be used to identify ongoing and locally controllable sources of PCBs to the Great Lakes. The program was successful at developing environmental triggers to differentiate potential source areas from background PCB conditions in urban areas, allowing efforts to focus on identifying active ongoing sources of PCB contamination. Project Trackdown has been carried out in three tributaries to Lake Ontario (Cataraqui River, Etobicoke Creek and Twelve Mile Creek) and two tributaries that flow into the Detroit River (Turkey Creek and Little River). Local ongoing PCB sources have been identified in four projects, leading to abatement or remediation measures. As a collaborative initiative between the Ontario Ministry of the Environment and Environment Canada, Project Trackdown has successfully identified several PCB sources leading to substantial cleanup efforts aimed ultimately at reducing PCB contamination to the Great Lakes.N.

“…Due to the episodic nature of runoff, point sources, and atmospheric deposition, bivalves that filter particles from water make a good matrix for contaminant monitoring of PAHs. Use of bivalves (caged and in situ) for contaminant monitoring is conducted worldwide, nationally and regionally, because they are sedentary and integrate the contaminant signal in the surrounding environment temporally and spatially (Goldberg et al, 1978;Kauss & Handy, 1985;Cantillo et al, 1998;Chase et al, 2000;Gewurtz et al, 2002;O'Connor, 2002;Monirith et al, 2003;Richman & Somers, 2010;Richman, 2011;Beyer et al, 2017;Kimbrough et al, 2018). Specifically bivalves filter water and particles from the water column, some of the contaminants associated with these matrices are ingested and retained, allowing temporal pulses of contaminants in the environment to be integrated by bivalves.…”

The National Oceanic and Atmospheric Administration (NOAA), National Centers for Coastal Ocean Science (NCCOS) Mussel Watch Program (MWP), conducts basin-wide monitoring and place-based assessments using dreissenid mussels as bioindicators of chemical contamination in the Laurentian Great Lakes. Polycyclic aromatic hydrocarbons (PAHs) body burden results for the period 2009–2018 were combined into one dataset from multiple MWP studies allowing for a robust characterization of PAH contamination. Patterns in PAH data were identified using descriptive statistics and machine learning techniques. Relationships between total PAH concentration in dreissenid mussel tissue, impervious surface percentages, and PAH relative concentration were identified and used to build a predictive model for the Great Lakes Basin. Significant positive correlation was identified by the Spearman’s rank correlation test between total PAH concentration and percent impervious surface. The findings support the paradigm that PAHs are primarily derived from land-based sources. Offshore and riverine locations had the lowest and highest median total PAH concentrations, respectively. PAH assemblages and ratios indicated that pyrogenic sources were more predominant than petrogenic sources and that PAHs at offshore sites exhibited relatively more weathering compared to inshore sites.
