In accordance with Column 2 adaptation statement of REACH Annex VIII, information requirement section 9.3.1, the determination of adsorption coefficient based on the physicochemical properties the substance can be expected to have a low potential for adsorption. The octanol water partition coefficient of MITC was estimated at 1.9. Based on this value we can safely conclude that MITC is characterized by a low potential of adsorption.

The ready biodegradability of methyl isothiocyanate was evaluated in a study performed in accordance with OECD testing guideline 301 D and GLP requirements. The maximum level of biodegradation was 0 % in 28 days. Therefore, according to these results, methyl isothiocyanate is not considered as readily biodegradable.

Using conditions representative of the upper Sacramento River system, site of a metam-sodium spill, hydrolysis half-lives in a buffered system were determined to be 65 and 178 days at 25 and 0 deg C, respectively, and a pH of 7.0; results at pH 10 were 0.7 and 10 days at 25 and 9 deg C, respectively, and at pH 4, half-lives of 15 and 67 days at 25 and 0 deg C, respectively, were reported. Nevertheless, these data should be considered with care because little information is available in order to challenge the validity of the data.
