魚貝類中多氯聯苯及多溴聯苯之調查研究

STUDIES ON PCB AND PBB IN FISHES

為瞭解魚貝類受多氯聯苯及多溴聯苯污染程度，在全省各地購得檢體共計200件，並加以分析，結果顯示多氯聯苯在各種魚貝類中含量範圍如下：海水魚未檢出～411.4ppb；淡水魚1.1269.3ppb；蛤0.6～13.1ppb；蟹肉2.4～26.5ppb；蟹黃11.3～22.4ppb；鮮蝦1.5～8.5ppb；牡蠣3.0～110.0ppb；墨魚類1.9～41.2ppb；九孔1.8～3.7ppbo本省產之魚貝類及進口魚類含量較高，而離島蘭嶼水產均極微量。 To analyze PCB and PBB contained in fishes, 200 samples were purchased from the markets and retails store all over the island. The PCB detected in sea fishes was in the range of ND~411.4ppb; in fresh-water fishes 1.1~269.3ppb; in tape 0.6 13.1ppb; in crabmeat 2.4~26.5ppb; in crab egg 11.3~22.4ppb; in shrimp 1.5~8.5ppb; in ostrea 3.0~11.0ppb; in cuttle fish 1.9~41.2 ppb, and in small abalone 1.8~3.7ppb. No PBB contamination was found in all samples. The results showed that the highest contamination by PVB was found in sea fishes, but it seemed to PCB pollution occurred the orchid island area.
