TBT was detected in all samples: 0.3-0.8 ng/l in bottom seawater, 4.4-16 ng/g dry wt in sediment, and 1.8-240 ng/g dry wt in various organisms. TBT and TPT concentrations were lower in bottom seawater than in shallower coastal waters. The TPT concentration in bottom seawater was less than our detection limit (0.9 ng/l), but it was 3.9-12 ng/g dry wt in sediment and 5.0-460 ng/g dry wt in organisms. TPT concentrations in deep-sea sediments and organisms were similar to those in coastal areas and higher in organisms at higher trophic levels, suggesting that TPT bioaccumulates through the food web. However, no such trend was observed for TBT. A laboratory rearing experiment demonstrated that sediment-sorbed TBT and TPT can be transferred to polychaetes. We conclude that TPT can be transferred to benthic organisms from sediments and then bioaccumulate through the food web. Sediments can thus act as a secondary source of TPT.", "subitem_description_type": "Abstract"}]}, "item_4_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt":
