为了解金竹洞和犀牛洞内重金属污染状况以及影响裸灶螽对重金属富集的主要环境因子,为进一步研究裸灶螽是否可以作为洞穴重金属污染的指示动物提供科学数据,在考察洞穴相关环境因子的基础上,采用AA800原子吸收光谱仪和6300原子荧光光谱仪,对采自洞穴土样、水样和裸灶螽样品的重金属含量进行了测定,并对裸灶螽的重金属富集系数和洞穴土壤的污染情况进行了对比分析。结果显示,所考察的6种重金属元素在土壤中的含量大多数超过我国的土壤背景值。其中,金竹洞内裸灶螽对土壤中重金属富集系数最大的是有光带的Cu(2.16),最小的是黑暗带的As(0.01);犀牛洞内裸灶螽对土壤中重金属富集系数最大的是黑暗带Zn(1.21),最小的是弱光带 As(0.04)。而水体中,金竹洞重金属富集系数最大的为有光带的 Zn (8200),最小的为黑暗带的Ni(28.16);犀牛洞重金属富集系数最大的为黑暗带的Zn(15385),最小的为弱光带的Ni(71.76)。重金属富集系数与部分环境因子的相关性分析表明,影响裸灶螽对土壤重金属富集系数的主要环境因子是pH值和有机质含量,重金属As与有机质呈显著负相关,相关系数为-0.926,Zn与pH值呈显著正相关,相关系数为0.817。综合污染指数显示,目前金竹洞为中污染,应引起当地政府注意,而犀牛洞为轻污染,虽有重金属污染,可污染不严重。
為瞭解金竹洞和犀牛洞內重金屬汙染狀況以及影響裸竈螽對重金屬富集的主要環境因子,為進一步研究裸竈螽是否可以作為洞穴重金屬汙染的指示動物提供科學數據,在攷察洞穴相關環境因子的基礎上,採用AA800原子吸收光譜儀和6300原子熒光光譜儀,對採自洞穴土樣、水樣和裸竈螽樣品的重金屬含量進行瞭測定,併對裸竈螽的重金屬富集繫數和洞穴土壤的汙染情況進行瞭對比分析。結果顯示,所攷察的6種重金屬元素在土壤中的含量大多數超過我國的土壤揹景值。其中,金竹洞內裸竈螽對土壤中重金屬富集繫數最大的是有光帶的Cu(2.16),最小的是黑暗帶的As(0.01);犀牛洞內裸竈螽對土壤中重金屬富集繫數最大的是黑暗帶Zn(1.21),最小的是弱光帶 As(0.04)。而水體中,金竹洞重金屬富集繫數最大的為有光帶的 Zn (8200),最小的為黑暗帶的Ni(28.16);犀牛洞重金屬富集繫數最大的為黑暗帶的Zn(15385),最小的為弱光帶的Ni(71.76)。重金屬富集繫數與部分環境因子的相關性分析錶明,影響裸竈螽對土壤重金屬富集繫數的主要環境因子是pH值和有機質含量,重金屬As與有機質呈顯著負相關,相關繫數為-0.926,Zn與pH值呈顯著正相關,相關繫數為0.817。綜閤汙染指數顯示,目前金竹洞為中汙染,應引起噹地政府註意,而犀牛洞為輕汙染,雖有重金屬汙染,可汙染不嚴重。

An investigation was done in Jinzhu Cave and Xiniu Cave to collect general information on heavy metal pollution and environmental factors affecting the heavy metal enrichment in Diestram-mena sp.The investigation was also aimed to provide further scientific data for the research that whether Diestrammena sp.can serve as an indicative animal affected by heavy metal pollution .The Atomic Absorption Spectroscopy ( AAS ) AA800 and the Atomic Fluorescence Spectroscopy ( AFS ) 6300 were employed to determine the content of heavy metals in soil , water and Diestrammena sp.A comparative analysis was conducted on the correlation between enrichment coefficients of heavy metal in Diestrammena sp.and the soil pollution in both caves .The results are as follow:the enrichment cofficients of the six tested heavy metals in the soil generally exceed the average background soil content of the country .Specifically , in Jinzhu Cave , the highest enrichment coefficients in Diestram-mena sp.come respectively from Cu (2.16) in soil and Zn(8 200) in water in the light zone , while the lowest respectively come from As ( 0.01 ) in soil and Ni ( 28.16 ) in water in the dark zone .In Xiniu Cave, the highest enrichment coefficients in Diestrammena sp.come respectively from Zn (1.21) in soil and Zn(15 585) in water in the dark zone, while the lowest comes from As(0.04) in soil and Ni(71.76) in water in the dysphotic zone .The analysis on correlation between enrich-ment coefficients of heavy metals and environmental factors shows that it is pH valne and the con-tents of organic matters that have an inflence on the enrichment coefficients of heavy metals in Diestrammena sp.The correlation coefficients are described here: As and organic matter ( signifi-cantly negtative at -0.926), Zn and pH value (significantly positive at 0.817).The comprehensive pollution index reveals that Jinzhu Cave is in medium level pollution and Xiniu Cave is in light level pollution .
