Multiple tests with fish demonstrate a low aquatic toxicity. The lowest 96-hour LC50 value of 210 mg/L is from a study with the freshwater Brachydanio rerio (new name: Danio rerio) conducted under OECD guidelines. Using ECOSAR calculations, algae are assumed to be the most sensitive species. A 96 -h EC50 of 77 mg/l is estimated and this value will be used in the hazard assessment of the substance.

Long-term aquatic tests are not considered necessary, because no significant long-term exposure is expected. Due to the fact that vinyl chloride is a gas, no significant concentrations are present in the fresh water and seawater compartment. This is supported by exposure assessment with EUSES. A regional PEC in fresh surface water of 4.18E-06 mg/L and a regional PEC in seawater of 3.44E-07 mg/L were calculated. The maximal local PEC value that was calculated for fresh water was 3.65E-02 mg/L (for S-PVC production). The maximum local PEC value that was calculated for seawater was 3.65E-03 mg/L (for S-PVC production).
