Soil nickel screening

Overview

Stub. Pending dedicated content describing how soil nickel concentrations are screened in the supply chain — relevant to crop-uptake risk assessment for cocoa, oats, legumes, and other nickel-bioaccumulator commodities. The EPA Eco-SSL (Ecological Soil Screening Level) framework provides plant-based and soil-invertebrate-based screening values that supply-chain actors can use to flag growing regions warranting commodity-level monitoring.

The page should populate with:

• The plant-based Eco-SSL for nickel (38 mg/kg dry soil).
• The soil-invertebrate-based Eco-SSL for nickel (280 mg/kg).
• Use cases for screening: pre-planting site evaluation, contract-farming risk tiers, and post-harvest commodity testing prioritization.
• Distinction between ecological screening (above) and human-health-protective soil values (different framework, different reference doses).

See Nickel for the cross-source Ni synthesis and EPA Eco-SSL Ni 2007 for the source EPA derivation document.
