Description of key information
Additional information
The calculated Henrys Law Constant indicates that the substance will evaporate from the water surfaces into the atmosphere. Furthermore binding to the solid soil phase (e. g. clay) is not expected due to low the log Koc of 1.12.
Mackay Level III simulations were used to evaluate the effect of source of entry on the distribution and persistence of chloromethane. As expected, the emission of chloromethane directly to air resulted in > 99% of the total chemical mass residing in the air compartment, with advection in air representing the primary mechanism of removal. Degradation in air represented only a minor amount of the total chemical mass (< 1%) removed from the system. Intermedia exchange of chloromethane between the other compartments was insignificant. Similar results were obtained when the chloromethane emission was to the soil compartment. Because of the relatively high vapour pressure of chloromethane, only 3.6% of the total chemical mass remained in the soil compartment whereas 96% was found in the air compartment. Hence, the primary removal process from soil was volatilization and the primary removal process from the system was advection in air. Local persistence was about 4 days, regardless if the chloromethane emission was to the air or soil compartment. In contrast to that observed for emission to the air and soil compartments, emission of chloromethane to the water compartment resulted in only about 20% the total chemical mass residing in the air, whereas about 80% remained in the water. Intermedia exchange of chloromethane with the other compartments (e. g. soil and sediment) was insignificant. The dominant removal mechanism of chloromethane from the system was advection in air, which was equal to the rate of volatilization from the water compartment. However, advection and degradation in water also removed significant amounts (28% and 2.4%, respectively) of the total chemical mass. Nonetheless, local persistence was about 15 days. Insignificant amounts of chloromethane will be found in the soil or sediment compartments, regardless of source of entry to the environment. Since chloromethane is a gas, most industrial releases are expected to be directly to the air compartment.
