The Swan Hills Treatment Centre (SHTC) is a facility for the safe disposal of special wastes located approximately 12 km northeast of the town of Swan Hills, AB. On October 16, 1996, a malfunction of a transformer furnace was discovered to have caused the release of a portion of process gases containing polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) into the ambient air. These chemicals can be harmful to human health. Therefore, in 1997 Alberta Health (AH) conducted a human health risk assessment study to estimate human exposure and to evaluate the effectiveness of public health interventions. As a result of the study, food consumption advice for wild game and fish taken within a 30 km radius of the facility were issued out of concern that PCBs and PCDD/Fs were accumulating in these locally caught foods. A long-term environmental monitoring and human exposure assessment program has been ongoing since 1998 to monitor concentrations of...

Description

The primary objective of the study was to provide a summary of the diet data and any major patterns in the diet of fish from waterbodies within the study area. The analysis included the three diet content methods used (frequency of occurrence, percent composition by count, and percent composition by weight; see Section2.1 for details) and presentation of temporal (years and where appropriate months) and spatial patterns for the fish species among the river systems.
