中文摘要 | 高都公園原為西青埔垃圾掩埋場,地層下有垃圾層及事業廢棄物。附近河道曾為配合公園改道,底泥充作填土材料,影響區約四萬平方公尺。公園整地曾挖填方各約一百七十萬方,使土壤特性更加複雜。本研究目的在對高都公園土壤環境及地被植物進行監測,探討該公園土壤中重金屬等污染物移動與植物的關係。土壤質地顯示覆土源極一致,應為原地土壤;垃圾層堅實,使水份不易下滲易積水;土壤pH值層間變化大,30公分深度間pH值差異達4個單位;層間電導度最大差異為1,300μmho/cm,背景樣點排水不良是造成鹽類聚集60-120公分處的原因;土壤汞、砷、鎳及銘濃度都低於背景值上限;土壤鋅、銅、鉛及鎘淒度30公分層間存在較大差異,部分高於背景值上限;植體中無法測得汞,故採食植體應無汞過量之憂慮;砷、鋅、銅、鎳、鉛、鋁及鎘含量分別為ND-1.2mg/kg、13-130mg/kg、6-32mg/kg、1.l-16mg/kg、0.3-8.2mg/kg、1.2-66mg/kg及0.3-1.9mg/kg之間;與土壤中鹽酸萃取濃度比較,植體鋅、銅、鎳、鉛、銘及鎘濃度多較高,在植體中有濃縮現象發生。 |
英文摘要 | Kaohsiung metropolitan park is a land-reused pattern of closed sanitary landfill site in Taiwan. Under the soil layer, there are tenth meters of rubbish and industrial waste. Sludge from button of nearby cannel, which upper reaches is industrial zone, was mixed with final cover. Affecting area is around 40,000 m��. During he park's construction, 1.7 million m�� soil was cutting and banking. All those operation influenced the topper soil's characteristic. The object of this study is to observe the moving and fate of heavy metals and salts in soil and plants. Results from soil texture indicate that soils with similar texture are come from same sources. Rubbish layer is firm, which makes water hardly leaching down. The changes of soil pH between layers are high in some zone in which 4 units pH difference appears in 30 cm soil's layer. The highest soil conductivity difference between layers is 1,300 μmho/cm. Fertilizing made half of the zones have higher conductivity in upper layer. Soluble salts concentrated in layers 60-120cm of background point is caused by its bed draining condition. Total As and Hg in soils are all lower than the suggesting background upper level. Zn, Cu, Pb and Cd concentration between some layers are high, and some of them are even higher than suggesting background upper level. Ni and Cr in soils are all lower than the suggesting background upper level. Plant tissues' Hg concentrations are all non-detectable. As, Zn, Cu, Ni, Pb, Cr and Cd contents in plant tissue are ranged from D-1.2, 13-130, 6-32, 1.1-16, 0.3-8.2, 1.2-66 and 0.3-1.9mg/kg respectively. Comparing heavy metals in plants with 0.1M HCI extractable in soils, Zn, Cu, Ni, Pb, Cr and Cd contents in plants are higher than in soils. Bioaccumulation is happened herein. |
