The key study examined the
biodegradability of LAS. A concentration of 34.3 mg/L LAS was added to
flasks containing activated sludge and the amount of CO2 evolved
was measured over the next 29 days by TIC analysis. The initial
bacterial count was determined to be 81 x 104 colony forming
units/mL using the Koch pour-plate method. The reference substance was
89% degraded in 29 days, signifying a valid test. LAS was found to be
85% degraded in 29 days, and therefore, LAS is readily biodegradable.
Although not a requirement for surfactants, LAS passed the 10-day window.
