    摘要: The accumulation of polychlorinated biphenyls (PCB) by brine shrimp (Artemia salina) was investigated in a short-term laboratory ecosystem. During 24-h of contamination, Artemia nauplii were found to rapidly accumulate significant amounts of PCB from aqueovs environments with PCB ranging from 1 ng mL-1 to 200 ng mL-1. The highest levels of PCB in the body of Artemia were found in the 200 ng mL-1 treatment group to be 1630 ng g-1(wet weight basis) within 24-h accumulation. A decreasing survival of the nauplii was observed with increasing PCB concentrations in aqueous environments. Percentages of PCB accumulation by Artemia in aqueous environments were also decreased by the increase of PCB concentrations. The elevated amounts of total suspended solids were also found to be the factor that affect the degrees of PCB accumulation in the larvae.
    本研究經由一項短期間實驗室生態設計,探討多氯聯苯在豐年蝦之蓄積。在24小時之多氯聯苯污染後,發現幼豐年蝦由含1ng mL-1至200ng mL-1之多氯聯苯蓄積量迅速的顯著增加,其中經由200ng mL-1污染處理之實驗組豐年蝦體有最高多氯聯苯之含量1630ng g-1(依據濕重);多氯聯苯在豐年蝦蓄積之百分比亦受到水中多氯聯苯濃度增加而有下降影響,隨著多氯聯苯濃度增加而幼蝦存活率低,亦造成總懸固形物量之增加而影響多氯聯苯在幼蝦體之蓄積程度。
