EPA Ecological Soil Screening Levels for Nickel (March 2007)
Summary
The March 2007 EPA Ecological Soil Screening Level (Eco-SSL) document for nickel provides soil concentration thresholds below which exposure is presumed to pose acceptably low ecological risk to plants, soil invertebrates, birds, and mammals. Eco-SSLs are screening tools for hazardous-waste-site evaluations under CERCLA, not human-health regulatory limits. The values are relevant to the wiki primarily as a supply-chain reference for evaluating agricultural soils for nickel contamination, given EFSA’s 2020 finding that dietary nickel exposure routinely exceeds the TDI in subpopulations.
