Protocol for the Derivation of Environmental and Human ... - CCME

Part A, Section 2
Industrial: where the primary activity involves the production, manufacture, or construction of goods.
The protocol identifies key biological receptors and exposure pathways which must be considered for
each land use to protect soil quality and maintain activities performed on these lands. The protocol
recognizes differences in analyzing human health and ecological issues. For each contaminant,
preliminary soil guidelines are developed for both ecological and human receptors. To protect both
human health and the environment, the most protective guideline is chosen as the final soil quality
guideline for individual land use categories.
The Subcommittee recognizes areas where the science dealing with soil-based human and ecological
toxicology and exposure is still developing. The Subcommittee therefore acknowledges the uncertainty
(i.e., Part B, Section 6.0) in some of the data used in the protocol. The Subcommittee is conservative in
their assumptions to protect human health and the environment under a broad range of possible
conditions.
