“…These observations are consistent with previous studies on macroinvertebrates impacted by primary WWTP effluents (deBruyn et al, 2003) and planktivorous fish influenced by primary sewage (Gaston and Suthers 2004). Our data are also in agreement with a recent study on Walleye and Northern Pike collected near the Montreal effluent (Pelletier et al, 2022). We hypothesized that the lower δ 15 N values of fish collected in the effluent plume relative to other sites reflected the difference in local interactions and cascading effects from bottom-up food source uptake.…”

“…Spatial Variations of δ 15 N in Fish δ 15 N is an important parameter generally used for modeling or comparing food chain structure and pelagic food web (Cabana and Rasmussen 1994;Vander Zanden and Rasmussen 1996;Vander Zanden et al, 1997), as well as a descriptor of contaminant bioaccumulation (Rasmussen et al, 1990;Cabana and Rasmussen 1994;Vander Zanden and Rasmussen 1996;Lapointe et al, 2020;Pelletier et al, 2022). δ 15 N can also be used to assess the influence of sewage on large river food webs (deBruyn et al, 2003) and nitrogen inputs from agricultural watersheds as resources of littoral food webs (Anderson and Cabana 2005).…”

“…Stable isotope analyses of carbon (δ 13 C) and nitrogen (δ 15 N) revealed that macroinvertebrates within the effluent plume downstream of Montreal WWTP effluent from the St. Lawrence River consumed sewage-derived resources, whereas those outside the effluent plume ingested seston and epiphytic resources deBruyn et al, 2003). Fish species feeding in the effluent plume also had a distinct δ 15 N isotopic signature vs. those feeding outside the effluent plume (Pelletier et al, 2022). How sewage-derived resources may influence δ 15 N and PFAS levels of piscivorous fishes in the St. Lawrence effluent-impacted area remains to be confirmed.…”

We examined the influence of Montreal wastewater treatment plant (WWTP) effluents on two top predators, Walleye (Sander vitreus) and Sauger (Sander canadensis), with a focus on δ15N isotopic signatures and per- and polyfluoroalkyl substances (PFAS). These two fish species were collected in the summer 2013 in the St. Lawrence River upstream and downstream from a major WWTP, as well as in background sites (semi-remote lakes). Most of the δ15N variations for Sauger and Walleye are attributable to 1) δ15N values of the primary producers and sewage-derived particulate organic matter (SDPOM) at the base of the trophic food chain, 2) agricultural activities combined with biogeochemical processes, and 3) food web length. δ15N was significantly lower in fish collected in the effluent-mixed water masses than other sites of the St. Lawrence River, attributed to the SDPOM of the WWTP effluent. Relative to the background sites, certain PFAS were present at much higher levels in the St. Lawrence River, with profiles dominated by perfluoroalkyl sulfonates (PFSA). However, PFSA profiles generally remained consistent along the St. Lawrence River. PFOS levels in fish from the St. Lawrence exceeded the current Federal Environmental Quality Guidelines for protecting piscivorous mammals or birds. However, the human chronic daily intake of PFOS remained below current thresholds suggested by national agencies.

“…Previous studies have been performed on the effect of WWTPs on live aquatic organisms. Pelletier et al (2022) report the bioaccumulation of cyclic volatile methylsiloxanes and linear siloxanes in a food web in the St Lawrence River, Canada, downstream of the Montreal WWTP discharge. It is suggested that the effects may stem from the various chlorinated agents (chlorine gas, chlorine dioxide and sodium hypochlorite) used.…”

The role of lysosomal membrane stability, malondialdehyde levels and DNA damage as pollution biomarkers in evaluating biological cleaning products using Mytilus galloprovincialis

The possible effects of wastewater treatment products on mussels (Mytilus galloprovincialis) were studied. Three common pollution biomarkers were used: neutral red retention assay, malondialdehyde contents and DNA damage through comet assay. Two groups of mussels were treated in the laboratory for 25 days with 20 and 40 %v/v of treated wastewater collected after chlorination, the control mussels formed a third group. The results showed statistically significantly lower neutral red retention times, higher malondialdehyde contents and higher formation of single-stranded DNA fragments in the mussels exposed at both treated wastewater concentrations compared to the controls.

“…VMS are released into the aquatic environment primarily through water treatment plants and sewage effluent (Fairbrother & Woodburn, 2016; Hong et al, 2014; Kirkegaard et al, 2013), with an estimated 6–21 tons of siloxanes annually ending up in waterways worldwide (Lassen et al, 2005). VMS have been measured in China (Guo et al, 2021; Hong et al, 2014; Xue et al, 2019), Baltic Sea (Kirkegaard et al, 2013), St Laurence River (Pelletier et al, 2022), Germany (Radermacher et al, 2020), Spain (Sanchis et al, 2016), South Korea (W. Wang et al, 2021), and Norway (Warner et al, 2014). Due to the high commercial use of siloxanes, human exposure occurs daily (Horii & Kannan, 2008), through inhalation, ingestion, and/or dermal contact (Lu et al, 2011; Mojsiewicz‐Pienkowska & Krenczkowska, 2018; Sanchis et al, 2016; Tran et al, 2019); however, toxicity is generally considered to be low (Lassen et al, 2005; Mojsiewicz‐Pieńkowska et al, 2016).…”

Siloxanes are used in personal care, biomedical, and industrial products. Their worldwide use and persistence in the environment cause consistent exposure for both humans and aquatic animals. Two siloxane congeners, decamethylcyclopentasiloxane (D5; CAS 541-02-6) and octamethylcyclotetrasiloxane (D4; CAS 556-67-2), are among the most prevalent, with measurable levels in air, sediment, water, and biological samples. However, few studies have examined the impact of developmental (embryo/larva) exposure. To address this gap, we performed parallel experiments using wildtype zebrafish (Danio rerio). One set of experiments used laboratory-mixed individual solutions containing either D4, D5, or 2,4,6,8-tetramethylcyclotetrasiloxane (D 4 H ; CAS 2370-88-9); the other used environmental water samples containing a mixture of siloxanes, including D4 and D5. These samples were collected from Bladensburg Waterfront Park (BWP) a site along the Anacostia River, Washington, DC. In both experiments, zebrafish (24-48 h postfertilization, hpf) were exposed until 7 or 14 days (d)pf. Chronic exposure to D4, D5, orBWP water until 7 dpf caused stress-like behaviors and reduced swim velocities; anatomical differences were noted only in BWP-exposed larvae. At 14 dpf, BWP-treated larvae still showed slower swimming velocities and increased immobility; anatomical differences were no longer evident and thigmotactic behavior was reduced. D4 and D5-exposed larvae did not survive after 10 dpf. Larvae exposed to D 4 H showed no decreases in behavior or growth at either age. These results suggest early developmental sensitivity to siloxane exposure and point to the need to consider embryonic/ larval endpoints when assessing aquatic contaminants.
