We have used several, complementary approaches to measure TAL biodegradability based on the OECD screening test. These include the use of radioactively labelled detergent measurements of the growth rates and maximum counts of microorganisms from natural sources on each component of TAL in a basal salts medium and finally, glc analysis of each component in solutions incubated with soil suspensions. The evidence accumulated to date suggests that the components of TAL are readily metabolised by microorganisms. 

The Modified OECD Screening Test, was applied to determine the ultimate biodegradation as the percentage of Total Organic Carbon (TOC) removal instead of Dissolved Organic Carbon (DOC) removal, after 7, 14, 21, and 28 days.
