2. The site-specific factors of human intake of contaminated soil and toxicity to soil invertebrates and plants specified in this matrix apply at all sites.

3. Standard has been derived based on results of clinical studies at sites. Standard represents the rounded sum of the toxicologically-based value plus the soil ingestion clinical study factor. For AL, PL and RL the soil ingestion clinical study factor is 80 µg/g. For CL soil ingestion the clinical study factor is 240 µg/g.
