“…A questionnaire survey conducted in 1996 reveals that half of fishermen from a local community near Montreal consumed their catch (Chan et al 1999), attaining as much as 20 kg of SLR-caught fish per year per person (Kosatsky et al 2000;Nadon et al 2002). Apparently, one-third of fishermen stopped eating local fish over the previous decade, due to the perception that fish are unsafe to consume because of the presence of contaminants (Chan et al 1999).…”

“…Apparently, one-third of fishermen stopped eating local fish over the previous decade, due to the perception that fish are unsafe to consume because of the presence of contaminants (Chan et al 1999). This perception largely still holds among the general public despite the scientific evidence that both Hg and PCBs levels in fish from the Montreal area have declined by 35-50 % and by 80-99 %, respectively, between 197680-99 %, respectively, between and 199780-99 %, respectively, between (Laliberté 2003.…”

The St. Lawrence River (SLR) is the second largest waterway in North America. The discharge of the City of Montreal wastewater treatment plant (WWTP) represents the largest volume of treated wastewaters being released into the river. It also ranks as the largest sewage treatment plant of its kind in North America. Over the last decade, intensive multidisciplinary research has focused on assessing the impacts of Montreal wastewater effluents on the SLR. We describe the major findings of these investigations, including the determination of the fate of contaminants, bioaccumulation in fish and invertebrates, ecotoxicological measurements of aquatic animal health, evaluation of endocrine disruption, parasitism in fish, and combined effects of multiple stressors on the SLR. Impacts of the effluents from the WWTP on aquatic organisms from the SLR are both toxicological and ecological, demonstrating the need for an integrated view of the impacts of municipal effluents on aquatic ecosystems.

“…In recent decades many studies have dealt with metal toxicity (Phillips and Russo, 1978;Handy, 1994;Awadallah et al, 1985;Dallinger et al, 1987;Chan et al, 1999;Soylak et al, 1999;Rased, 2001;Hiller et al, 2010;Gurkan and Ulusoy, 2010;Alkan et al, 2012;Papadimitriou et al, 2012;Mitra et al, 2012;Mendil et al, 2005), but in area around Sasa mine there is a lack of such studies.…”

Analyses identified high levels of Cr, Hg, Ni and Pb in studied animals, which also exceeded their permissible levels in food. In sediment and soil samples, levels of Cd, Cu, Cr, Pb, Zn and As were perceived, while Cd, Cu, Ni, Pb, Se and As were increased in water samples. Results of transfer factor revealed that the examined animals had higher bioaccumulation rate from surrounding waters than from sediments or soils. The accomplished Health Risk Index disclosed that studied animals can have considerably high health risks for inhabitants. Conclusively, they could be considered as highly contaminated with metals and can consequently harm human health, especially children in their early development stages.

“…This is well supported in the literature on First Nations health, where authors frequently call for more holistic and culturally specific approaches in risk assessment (e.g., Judd et al, 2004;Richmond et al, 2005;Chan et al, 1999). Furthermore, failure to account for these potential impacts amount, in the words of O'Neill (2003), to "... a means by which the dominant society continues to dismantle the cultural bonds of indigenous peoples and to sanction the destruction of the land and resources that are crucial to the flourishing of these peoples" (3).…”

“…For example, First Nations people who engage in cultural practices such as subsistence hunting may experience an increased risk of exposure to environmental contaminants (Usher et al, 1995). On the other hand, if a perception of risk of environmental contaminants is present among a First Nation, members may choose to shift away from cultural activities such as subsistence hunting, which may also have negative health affects (Chan et al, 1999;Kuhnlein & Chan, 2000;Kuhnlein & Receveur, 1996). It is, therefore, important to consider the multiple ways in which social and cultural constructions of risk may contribute to producing better risk assessments.…”
