中文摘要 | 二仁溪是屬於污染相當嚴重之河川之一。從早期綠牡蠣事件,到去年之底泥又生物體檢測出戴奧辛,二仁溪無慮的是以污染而聞名全省。在二仁溪沿岸,雖膾相關單位已嚴可管理當地之金屬回收業以防止污染,但目前仍可發現非法業者之露天焚化及酸洗作。除此之外,此區亦有不少養殖魚塭,有些魚塭即位於前述之熔煉場旁。因此,魚塭中養殖之水產。極有可能因熔煉作業產生之污染物(如金屬等)而受到污染。為確定此可能性,我們選取鄰近有金屬熔煉場之魚塭,共四處為採樣點;另取台南縣北門鄉附近之一處魚囍做為參考點。其中每點抓取3~6尾魚(總計24樣本數,每含19尾虱目魚及5尾吳郭魚)以測定其體內五種金屬(鉛、鎘、鋅、鎘、鎳) 之吉量。初步結果顯示其中一魚囍之虱目魚體內?較高(如與參考點比較)的銅(1.51~3.87ug/g乾重)、鉛(0.07~1.59ug/g乾重)、鎘(未測得~0.10ug/g乾重),但較晚之一次同集,魚體中金屬含量卻無偏高現象。其他魚塭中之虱目魚體內金屬含量則與參考點之魚體相近。另外,一魚塭中吳郭魚體內之鋅(50.25∼61.26ug/g乾重)、銅(2.14~2.64ug/g乾重),及鉛(未測得~2.88ug/g乾重)皆比參考點之虱目魚高(鎘與鎳未測)。更進一步之調查及增加樣本數仍有必要。 |
英文摘要 | Milkfisn (chanos chanos) from aquaculture ponds near Er-Jen Rier, one of the most polluted water system in Taiwan, were sampled to determine metal contents in the tissues. We found zinc and copper in these fish were not that different fro the fish from a reference pond. Other metals in milkfish, such as Ni, Cd and Pb, were mostly not detected. We also analyzed tlapias (Tilapia sp.) rom another pond. Metals in this species had higher contents than milkfish from either the investigated or the reference pond. Further resarches are needed to gather more information. Especially in increases in sample sizes, selection of sampling location, and implemenlation of the QA/QC program in our analytical procedure. |
