Proposals for Intervention Values for Soil and Groundwater, including the211 Calculation of the Human-Toxicological Serious Soil Contamiination 211 Concentrations: Fourth Series of Compounds

摘要

The meaning of the Intervention Values is as follows: If the average total soil211u001econtent in a soil volume of at least 25 cu m exceeds the Intervention Value for 211u001esoil, or when the concentration of the groundwater in a water-saturated soil 211u001evolume of at least 100 cu m exceeds the Intervention Value for groundwater. The 211u001ereport documents the derivation of proposals for Intervention Values for 15 211u001eadditional compounds or compound groups (the fourth series of compounds) as 211u001elisted below: metals: vanadium, selene, thalliu, tellurium, tin; aromatic 211u001ecompounds: chloroanilines, 4-chloro-methylphenol; chlorinated hydrocarbons: 1,1,2-211u001etrichloroethane, 1,2,/1,3-dichloropropane, 1,1-dichloroethane; pesticides: MCPA 211u001e(4-chloro-methylphenoxy-acetic acid); miscellaneous compounds: tribromomethane, 211u001eisopropanol, ethylacetate and butylacetate.
