| Abstract: | 彰化縣工業以電鍍及金屬表面處理業為主，污染物易隨著水體匯集到沿海地區，而彰化沿海地區為水鳥重要之覓食與棲息地。為了進一步瞭解環境與生物體的重金屬蓄積程度，因此本研究嘗試利用彰化海岸地區度冬與春過境期間的黑腹濱鷸胸羽(鎘、銅、鉻、鎳與鉛)與鄰近環境之沉積物(鎘、銅與鉛)，探討兩者間重金屬濃度是否存在隨時間與空間變化之相關，以及黑腹濱鷸胸羽中各金屬濃度是否存在性別、年齡與不同換羽時期的差異，並討論羽毛中重金屬濃度與體重之相關性，以提供沿海環境與生物中的重金屬濃度相關資料。 分析31筆彰化沿海地區沉積物中重金屬濃度，顯示平均濃度由高至低分別為銅(33.7±23.4 ug/g)>鉛(22.5±5.4 ug/g)>鎘(0.47±0.17 ug/g)，另外鎘濃度在不同樣點間具有顯著差異，銅與鉛則呈現無顯著差異，而三種重金屬隨濃度時間變化依重金屬元素不同而異。分析77筆黑腹濱鷸羽毛中重金屬，平均濃度由高至低分別為銅(211.1±136.3 ug/g)>鉛(67.2±51.4 ug/g)>鉻(22.7±33.4 ug/g)>鎳(8.7±9.5 ug/g)>鎘(5.4±5.7 ug/g)，其中黑腹濱鷸胸羽中各重金屬濃度在性別間皆呈現無顯著差異(P>0.05)，鎳在成鳥與亞成鳥間存在有顯著差異(P<0.05)，銅與鎳在完成換羽時期與繁殖羽換羽時期之間存在顯著的差異(P<0.05)，鉻、鎳與鉛於繁殖羽換羽時期與鳥體體重呈現顯著相關性(P<0.05)。黑腹濱鷸與沉積物重金屬濃度在時間與空間上的相關結果，呈現只有鉛在和寶溪口沉積物與黑腹濱鷸胸羽中有良好的線性相關，表示從黑腹濱鷸胸羽中重金屬濃度分析無法完整的呈現潮間帶環境的重金屬污染情況，因此可能需更精確的實驗設計來驗證之間的關係。
Industrial activities in Changhua are mainly consisted of electroplate industry and metal surface treating. The drainage containing contaminated chemicals affect the coastal ecology. However, Changhua coastal area is an important feeding habitat for shorebirds. In my study, I analyze the samples to know the level of heavy metal bioaccumulation in organism and environment. In addition to, I want to understand the relationship of concentration of heavy metals in temporal and spatial variation between the breast feathers of Dunlins (cadmium, copper, chromium, nickel and lead) with environmental sediment (cadmium, copper and lead) at Changhua coastal area in winter to spring migration season. The differences of metal concentrations in the breast feathers of dunlins between sex, age and different molting stage were examined. Moreover, I tested the correlations between the weight and heavy metal concentrations were investigated in feathers of Dunlin. The results are provided some information in heavy metal concentration of organism and coastal environment. Firstly, Results showed mean concentrations of heavy metal of sediments (n=31) were listed in order: Cu(33.7±23.4 ug/g)> Pb(22.5±5.4 ug/g)> Cd(0.47±0.17 ug/g). The sediment concentrations of cadmium was significantly different among different sites. However, copper and lead concentrations were found no significant difference. Secondly, the mean concentrations of heavy metal of Dunlin feathers (n=77) were listed: Cu(211.1±136.3 ug/g)> Pb(67.2±51.4 ug/g)> Cr(22.7±33.4 ug/g)> Ni(8.7±9.5 ug/g)> Cd(5.4±5.7 ug/g). In all elements, there were no significant difference (P>0.05) of heavy metal concentration between male and female, and the concentration of Nickel in feathers was significantly different (P<0.05) between adult and juvenile. Copper and nickel concentrations in Dunlin feathers were significantly different (P<0.05) in different molting stage . Chromium, nickel and lead, there were found significant correlations (P<0.05) between concentration of feathers and body weight. Finally, the analysis of the concentrations in dunlin feathers and sediments, there was only good correlation of concentration in Pb at Heo-Pao estuary. It’s meant the results of my analysis can’t show the status of heavy metal pollution in intertidal habitat completely. I suggest to do more experimental designs to improve the correlations. |
