摘要
2009年6月对贵州安顺市山岚桥洞内软体动物和节肢动物进行了采集。共获标本637号,初步鉴定隶属于2门4纲7目12科25种,合并为螺类、马陆、盲蛛、斑灶马、山蛩虫5个类群。利用原子吸收光谱仪和原子荧光仪测定洞内水、土壤及洞穴中5个类群动物体内的Pb、Cd、Hg、As、Cu、Zn、Cr、Ni8种重金属含量,计算水、土壤中重金属在动物体内的富集系数。结果表明,水、土壤及动物体内的Zn含量最高,水样为112.90μg/L,土样为224.60mg/kg,5个动物类群体内,螺类146.80mg/kg,马陆252.20mg/kg,盲蛛556.80mg/kg,斑灶马233.30mg/kg,山蛩虫722.50mg/kg;5个类群动物对洞穴土壤中Cd、Cu和Zn有明显的富集作用,富集系数均大于1;对洞穴水中As、Cu、Zn、Ni等有明显富集作用,富集系数大于1000。同种动物类群对不同重金属的富集系数不同,不同类群对同种重金属元素的富集系数也有差别。洞穴动物对重金属的富集作用,除了与元素之间相互关联外,还与环境有密切关系。
We sampled invertebrates,water,and soil at Shanlanqiao Cave,Anshun County,Guizhou Province in June 2009. We identified 25 species belonging to 12 families,7 orders,4 classes and 2 phyla from 637 samples and grouped them into spiral shells,millipedes,Opiliones,Diestrammena marmorata,Orthomorpha 5 groups. We measured the content of 8 heavy metals Pb,Cd,Hg,As,Cu,Zn,Cr,Ni in the five animal groups and in the water and soil samples by atomic absorption spectrometer and atomic fluorescence spectrometer. The content of Zn was highest among 8 metals,in water （112. 90 μg /L）,soil （224. 60 mg / kg）, spiral shells （ 146. 80 mg /kg ）, millipedes （ 252. 20 mg /kg ）, Opiliones （ 556. 80 mg /kg ）, Diestrammena marmorata （ 233. 30 mg /kg） and Orthomorpha （ 722. 50 mg /kg）. Animal samples contained higher Cd,Cu and Zn than the soil samples did with an accumulation index 1; while the accumulation index of As,Cu,Zn,Ni was 1 000 in the animal samples copared with water samples. The same animal group had different accumulation index on different heavy metals,and different groups had different accumulation index on same heavy metal. The content and enrichment of heavy metal in animal samples might be related with theenvironment and with the relation between elements of heavy metal.
