Tributyltin in blood of marine fish collected from a coastal area of northern Kyushu, Japan

2011

We investigated levels of the pollutant tributyltin (TBT) in blood of pufferfishes (six species), Japanese sea perch, red sea bream, Japanese common goby, Japanese flounder, rockfish, conger eel, and sea mullet collected off the coast of northern Kyushu, Japan. We found considerable levels of TBT (1.4–190ng/mL) accumulated in the blood of these fish. Blood TBT concentrations were 1.3–22.5times liver concentrations and 4.9–78times muscle concentrations, except in conger eel and mullet. We detected TBT (16–111ng/mL-blood) in the plasma of the fine-patterned puffer (Takifugupoecilonotus) year-round, without any apparent seasonal trend. These results suggest that fish inhabiting coastal areas of Kyushu, Japan, continue to be contaminated with TBT.
