Distinctive Features of the Threat

  • The Maximum score for the environmental threat is 60 rather than 100.

  • Bioaccumulation comes into play for this threat as well as for the human food chain threat.

    • The Maximum value for waste characteristics is 1,000 rather than 100. This means that high threat scores can be obtained with relatively few target points.
    • Aqueous samples are required for Level 1 concentrations. Frequently, however, Level II can "max out" the threat score at 60.

  • A variety of sensitive environments plus wetlands are the targets. There is no assessment of "nearest environment" in this threat.
