No fact sheet created. For more information on this guideline, please refer to Canadian Water Quality Guidelines (CCREM 1987). This guideline (originally published in Canadian Water Quality Guidelines [CCREM 1987 + Appendixes] in 1987 or 1991 [PCBs in marine waters]) is no longer recommended and the value is withdrawn. A water quality guideline is not recommended. Environmental exposure is predominantly via sediment, soil, and/or tissue, therefore, the reader is referred to the respective guidelines for these media. This substance meets the criteria for track 1 substances under the national CCME Policy for the Management of Toxic Substances (PMTS) (i.e., persistent, bioaccumulative, primarily the result of human activity, and CEPA-toxic or equivalent), and should be subject to virtual elimination strategies. Guidelines can serve as action levels or interim management objectives towards vitual elimination. | |

Data are sufficient and adequate to calculate only a Soil Quality Guideline for Environmental health (SQGE). An interim soil quality criterion (CCME 1991) was not established for this land use, therefore the SQGE becomes the soil quality guideline. For guidelines derived prior to 2004, differentiation between soil texture (coarse/fine) is not applicable. The term total DDT refers to the sum of the concentrations of p,p’-DDT, o,p’-DDT, p,p’-DDE, o,p’-DDE, p,p’-DDD, and o,p’-DDD. | |
