Lake-wide averages for polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDDs/PCDFs) were 100 ng/g and 111 pg/g TEQs, respectively.

In addition, levels of a suite of eight metals were compared to pre-colonial concentrations, and surficial sediment enrichment factors were calculated. Concentrations of PCBs at all sampling stations were below the Canadian PEL of 277 ng/g. I roll it between my fingers, smack my lips a few times and tell them if it tastes salty or not.
