Title: Comparative kinetics study of the evolution of freshwater aquatic toxicity and biodegradability of linear and branched alkylbenzene sulfonates

Abstract

Evolution of both primary biodegradability and acute toxicity to daphnia and zebra fish of a linear alkylbenzene sodium sulfonate (LAS) and a branched alkylbenzene sodium sulfonate (BAS) have been measured simultaneously. In six of eight experiments, LAS was biodegraded to 90% in 7 days and BAS to 70% in 7 days. In the two other experiments, both LAS and BAS have shown the same biodegradation speed and reached the same biodegradation level in 7 days: 45% in one experiment and 55% in the other. The composition of bacteria population and the level of cellular ATP of the inoculum play a decisive role in the biodegradation. These results confirm that it is essential to know the composition of bacteria population present in the inoculum as well as their biochemical characteristics to accurately interpret results of biodegradation tests. In the case of a rapid primary biodegradation of LAS and BAS, the acute toxicity of LAS remains three times as high as that of BAS for at least 24 hr toward daphnia and 48 hr toward zebra fish. Their acute toxicity to daphnia and zebra fish become equivalent only after 72 hr. When primary biodegradation of both products is slower, the acute toxicitymore » of LAS remains higher than that of BAS for more than 7 days.« less
