Additional information

Due to the fact that vinyl chloride is a gas, no significant concentrations are present in the soil and air compartment. This is supported by exposure assessment with EUSES. A regional PEC in soil of 7.82E-09 (d.w.) and a regional PEC in the atmosphere of 3.53E-06 mg/m3 was calculated. The maximal local PEC value that was calculated for soil was 0.042 (d.w.) and for air 0.019 mg/m3 (for S-PVC production). Since these concentrations are very low, no significant exposure via the soil and air compartment is assumed and therefore studies on terrestrial organisms are not considered necessary.

In accordance with column 2 of REACH Annex X, the study on birds does not need to be conducted as sufficient reliable data is available from the mammalian data set.
