This report discusses the results from the following studies: 1. The results of analyses of deer taken within a 30 km radius of the facility and the reference areas in 1999, 2001, 2003 and 2007 for the levels of PCBs, PCDD/Fs and dioxin-like Toxic Equivalency (TEQ); 2. The results of analyses of brook trout taken from Chrystina Lake in 2000, 2003 and 2007 for the levels of PCBs, PCDD/Fs and dioxin [...] The results of these studies indicate that 1. As compared to the contaminant levels in deer in1997 in the area of the facility, the PCB levels in liver and muscle samples were statistically significantly decreased in1999 – 2007. [...] The results of analyses of tissues of deer taken within a 30 km radius of the facility and the reference areas in 1999, 2001, 2003 and 2007 for concentrations of PCBs and PCDD/Fs; (2). [...] Significantly higher levels of PCBs and PCDD/Fs in deer from the study area and similar PCB congener patterns observed in various media near the facility indicate that contamination has occurred in the ecosystems near the facility. [...] The PCB concentrations at distances to the facility fence in deer tissue samples collected between 1999 and 2007 are presented in Table 5. A hierarchical multiple regression analysis was conducted to determine the joint effects of distance from the Swan Hills Treatment Centre, the year in which the deer was taken, and the interactions on PCB concentrations in muscle and liver samples.
