Maximum acceptable concentration levels of the chemical agent sarin in Canadian and Russian soil types

The lowest-observed-adverse-effect and no-observed-adverse-effect concentrations of sarin were determined in soils typical to Canada and Russia. Maximum acceptable concentrations were established to be 3.0 × 10 −4 mg kg −1 for the standard reference soil, 2.0 × 10 −3 mg kg −1 for prairie soil, and 1.0 × 10 −2 mg kg −1 for forest soil.
