Additional information

The adsorption coefficient on soil (Koc) of cis-cyclooctene was determined as 1000 (log Koc = 3.0; 25 ºC). This is borderline between moderate and high on the Blume scale. The calculated Henry’s law constant of 36400 Pa m3/mol at 20 °C indicates high volatility of cis-cyclooctene from surface waters. According to a Mackay level I calculation cis-cyclooctene will be distributed almost exclusively to the atmosphere (99.86 %) while distribution to other compartments is negligible (< 0.1 %).
