Biotic degradation

Dibutyltin dichloride is not readily biodegradable in a study to the OECD 301B guideline, with a maximum of only 6% biodegradation observed after 28 days (Günzel et al, 1991). A published simulation test is available, however, it is not considered completely reliable. DT50s for DBT in the study are 12 to 18 days (Adelman et al, 1990), indicative that it is susceptible to biodegradation within the environment.
