Abstract
BIOSIS COPYRIGHT: BIOL ABS. The acute toxicities of three organotin compounds, i.e., monobutyltin (MBT), dibutyltin (DBT) and tributylin (TBT), to benthos (Chironomid larvae and tubificids) were reported. The results show that (1) the toxic effects of these compounds in a decreasing order were TBT DBT MBT; (2) the median lethal concentration (24h LC50) of TBT to 4 species of benthos was 26.85 ppb for chironomid larvae (Chironomus plumosus), 241.55 ppb for chironomid larvae (Chaetocladius sexpapilosus), 145.55 ppb for tubificids (Branchiura sowerbyi), and 355.63 ppb for tubificids (Limnodrilus hoffmesteri); (3) there was a strong negative correlation between the concentration of TBT and the median lethal time (LT5O) for B. sowerbyi.
