Invertebrates are harmed by pollution of their habitats. Litter-dwelling sedentary scorpions, such as Tityus pusillus, studied here, may be good models for examining the genotoxic effects of xenobiotics in soil. Thirty specimens were collected from five sites in Northeast Brazil with different levels of human disturbance, as well as a laboratory group. The comet assay was performed on hemolymph cell samples. Damage Index (DI) and Damage Frequency (DF%) were measured. Much higher genotoxicity was observed in animals collected in an area with human interference and solid waste, compared to those obtained in more pristine areas or the laboratory. T. pusillus may be a useful model for environmental genotoxicity assays.
无脊椎动物会因栖息地受到污染而受到伤害。在此研究的栖息于垃圾中的定居性蝎子，如蒂氏真蝎，可能是用于检测土壤中外源化合物遗传毒性效应的良好模型。从巴西东北部五个受人类干扰程度不同的地点以及一个实验室组收集了30个标本。对血淋巴细胞样本进行彗星试验。测量损伤指数（DI）和损伤频率（DF%）。与在更原始地区或实验室获得的动物相比，在受人类干扰和有固体废物的地区收集的动物中观察到更高的遗传毒性。蒂氏真蝎可能是环境遗传毒性检测的有用模型。
