The Ecological Soil Screening Level (Eco-SSL) derivation process is used to derive a set of risk-based Eco-SSLs for many of the soil contaminants that are frequently of ecological concern for plants and animals at hazardous waste sites.
The interim Eco-SSL documents for the chemicals listed below provide an overview of the contaminant, separate discussion for each receptor group including a comprehensive list of literature evaluated under the effort, and a summary of data used in deriving Eco-SSL values. The initial list of documents through Zinc are metal contaminants, and the documents that follow, beginning with DDT and Metabolites, are organic contaminants.
For additional information, see the Ecological Soil Screening Level site.
