Description of key information

Additional information

1,2-Dichloroethane is predominantly distributed in air (95 %) and only in minor portion into water (<4.8 %) which is supported by both the high vapour pressure ( 81.3 hPa at 20 °C) and the volatility of the substance (149 PA x m³/mol).

Based on both the water solubility and high volatility, adsorption to soil and sediments is not expected, which is supported by an experimentally determined KOC-value of 33 for silt loam (HSDB 2000) or 43 (Kenaga, E.E. (1980)).

Due to its chemical structure, the substance will not undergo both hydrolysis in water and photodegradation by direct sun-light. Field measurements confirmed that the photo-degradation in the atmosphere prevents the global distribution and the atmospheric enrichment of emissions, released by industry mainly in the northern hemisphere.
