Health Conference'97 - Great Lakes/St. Lawrence. Montréal, PQ, CAN, 1997/05/12.
A 1995 pilot study assessed sport fish consumption and contaminant exposure among Montreal-area residents fishing the frozen St.
Interviews conducted among 223 ice fishers met on-site were used to create an index of estimated exposure to fish-borne contaminants.
A second-stage assessment of sport fish consumption and tissue contaminant burdens included 25 interviewees at the highest level of estimated contaminant exposure (of 38, or 66% of those solicited) and 15 low-exposure fishers (of 41, or 37% of those solicited).
High-level fisher-consumers reported eating 0.92±0.99 sport fish meals/week during the previous 3 weeks compared to 0.38 ± 0.21 (P<0.05) for the low-level group.
Based on the product of consumption frequency times mass of sport fish meals consumed, high-level consumers ate a mean of 18.3 kg of sport fish annually versus 3.3 kg for the low-level consumers.
Tissue contaminant assessments showed significant (P<0.05) groupwise differences : 0-1 cm hair mercury (median 0.73 mug/g for the high versus 0.23 mug/g for the low group), lipid-adjusted plasma PCB congeners (Aroclor 1260 : median 0.77 mug/g versus 0.47mug/g), and lipid-adjusted plasma DDE (median 0.35 mug/g versus 0.26 mug/g).
No participant had a hair mercury or plasma DDE concentration above Health Canada recommendations but 2/25 high-level participants (8%) had plasma Aroclor 1260 concentrations above recommended limits. (...)
