Arsenic (Chemical Abstract Service # 7440-38-2)

Notes

1. All values in μg/g unless otherwise stated. Substances must be analyzed using methods specified in a director's protocol or alternate methods acceptable to the director.

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. Standards have been derived based on results of clinical studies at sites. Standards represent the rounded sum of the toxicologically-based value plus the applicable soil ingestion clinical study factor, if one is available. For AL, PL, and RL, the soil ingestion clinical study factor is 80 µg/g. For CL, the soil ingestion clinical study factor is 240 µg/g. For IL, no soil ingestion clinical study factor is available. For IL, the toxicologically-based value without addition of a clinical study factor approximates the CL soil standard, therefore the IL standard was set equal to the CL standard.

4. Intake pathway of exposure modeled is inadvertent ingestion of soil.

5. Standard has been adjusted based on a reference provincial background soil concentration. Standard represents the rounded sum of the toxicologically-based value plus the reference provincial background soil concentration. For all land uses, the reference provincial background soil concentration is 14.9 μg/g.
