测定了不同城市采样点的华北落叶松个体中镉、铅、铜和锌的含量。与来自参考地点的蜗牛相比，在城市中收集的动物显示出更高的镉，铅和铜浓度，表明金属污染水平升高。观察到对照动物和受污染蜗牛之间组织浓度的最显著差异是铅。在城市内，蜗牛中的金属水平差异显着，即使在相邻的population.Arianta arbustorum是一个合适的物种进行生物监测，因为它是广泛的，居民和易于收集，它有一个高容量的金属积累，并显示不同的浓度取决于采样区的金属污染。进行了种间比较的金属浓度在陆生腹足类，以确定背景水平和类的负担。根据蜗牛的金属负荷分为三个污染级别：无污染（第1类：参考地点）、中度污染（第2类：城市地区的交通和其他人类活动）和高度污染（第3类：采矿和重工业）。
Concentrations of cadmium, lead, copper and zinc were measured in individuals of Arianta arbustorum from different urban sampling sites. In comparison to snails from a reference site, the animals collected in the city showed higher concentrations of cadmium, lead, and copper, indicating elevated levels of metal pollution. The most pronounced difference in tissue concentrations between control animals and contaminated snails was observed for lead. Within the city, metal levels in snails differed significantly, even between adjacent populations.Arianta arbustorum is a suitable species for biomonitoring, because it is widespread, resident and easy to collect; it has a high capacity for metal accumulation and shows different concentrations depending on metal contamination of the sampling area. An interspecific comparison of metal concentrations in terrestrial gastropods was conducted to define background levels and classes of burden. Three pollution levels are distinguished on the basis of the snails' metal burden: no pollution (class 1: reference sites), moderate (class 2: traffic and other human activities in urban areas), and high pollution (class 3: mining and heavy industry).
