Bioaccumulation analyses of copper and zinc were carried out in two snail subspecies (Helix aspersa aspersa and Helix aspersa maxima) after 3 months of controlled farming (out of ground) with foods of different formulations. The results reveal some clear interspecific differences in affinity toward copper and zinc. For the two metals considered, H. aspersa aspersa has a bioaccumulation capacity much greater than that of H. aspersa maxima, mainly in the foot for copper and in the viscera for zinc. After 3 months, the concentrations of copper in feet and viscera are much higher than those presented in the literature on field animals. The farming and the analysis methodologies permitted obtaining snails under standard condition and open the way to the development of rational protocols for ecotoxicological studies in a laboratory as well as in the field.
在用不同配方食物进行3个月的受控养殖（室外）后，对两种蜗牛亚种（庭院蜗牛和玛瑙蜗牛）进行了铜和锌的生物累积分析。结果揭示了两种蜗牛亚种对铜和锌的亲和力存在明显的种间差异。对于所研究的这两种金属，庭院蜗牛的生物累积能力远大于玛瑙蜗牛，主要体现在铜在足部的累积以及锌在内脏的累积。3个月后，足部和内脏中的铜浓度远高于文献中报道的野外动物体内的铜浓度。这种养殖方式和分析方法能够在标准条件下获得蜗牛，并为在实验室和野外开展生态毒理学研究制定合理方案开辟了道路。
