Additional information

Dicyclopentadiene is not considered to be readily biodegradable. This substance is also expected to have low potential for bioaccumulation and adsorption to soil and sediment based on its log Kow of 2.78. Structural analysis of the substance molecule indicates that it is not expected to undergo hydrolysis in the environment due to the lack of hydrolysable functional groups. The calculated overall OH rate constant for dicyclopentadiene is 119E-12 cm3.molecule-1.s-1, which represents a half-life in the atmosphere of 1.1 hours.
