The biosorption and biodegradation of tributyltin (TBT) at sublethal concentration of the two microalgae Leptocylindrus danicus and Amphidinium carterae were investigated. The results showed that accumulation of TBT occurred in the two algae, the adsorption of TBT by the algal cell wall was a rapid process. The degraded products, dibutyltin (DBT) and monobutyltin (MBT), were not detected in the incubation...
