Woodlice are top consumers of a three-trophic system (soil, leaf litter, woodlice), and they are closely related to pollutant absorbing surfaces such as soil, leaf litter, and organic matter. We studied the effects of urbanization on trace element concentrations and fluctuating asymmetry of Armadillidium vulgare (Crustacea: Isopoda) individuals in and around Debrecen city, Hungary. Along an urbanization gradient (urban, suburban, and rural areas), trace element concentrations (Ba, Cu, Fe, Mn, Pb, and Zn) of woodlice and bioconcentration factor (BCF) were analyzed. Asymmetry was also measured in metric traits of woodlice: the length of three segments of antennae, the body length, and the width of the 3rd segment of pereon. We found significant differences in Ba and Cu concentration of A. vulgare individuals along the urbanization gradient. The highest Cu concentration was found in woodlice from the urban area and the highest Ba concentration was found in the individuals from the rural area. The Ba concentration was higher in females than in males. The BCF values of Cu indicated that A. vulgare accumulated this element from soil and leaf litter. There was no significant difference in symmetry of the bilateral traits of woodlice along the urbanization gradient based on FA levels. Our results showed that the urbanization had remarkable effect on the Ba and Cu concentration of woodlice which were originated from traffic pollution. At the same time, the anthropogenic activities did not affect the symmetry of the tested traits of A. vulgare individuals.
木虱是一个三营养级系统（土壤、落叶、木虱）的顶级消费者，它们与污染吸收表面如土壤、落叶和有机物密切相关。我们研究了城市化对匈牙利德布勒森市及其周边地区普通球鼠妇（甲壳纲：等足目）个体的微量元素浓度和波动性不对称的影响。在城市化梯度（城市、郊区和农村地区）上，分析了木虱的微量元素浓度（钡、铜、铁、锰、铅和锌）和生物浓缩系数（BCF）。还测量了木虱的形态特征的不对称性：触角的三个节段、体长和胸甲第 3 节的宽度。我们发现，普通球鼠妇个体的钡和铜浓度沿城市化梯度存在显著差异。铜浓度最高的是来自城市地区的木虱，而钡浓度最高的是来自农村地区的个体。女性的钡浓度高于男性。铜的 BCF 值表明，A. vulgare 从土壤和落叶中积累了这种元素。根据 FA 水平，木虱双侧特征的对称性在城市化梯度上没有显著差异。我们的结果表明，城市化对源于交通污染的木虱的钡和铜浓度有显著影响。同时，人为活动并没有影响 A. vulgare 个体测试特征的对称性。
