Environmental pollution caused by human activities is a global public health concern. This review discusses the impact of different types of pollutants such as pesticides, metals, nanoparticles and others on land molluscs. These molluscs are of great interest as good model organisms for studying biomarker responses in ecotoxicological monitoring programs. Several biomarkers are utilized to characterize and quantify the exposure and harmful impacts of various pollutants. In this review, we have identified physiological and behavioral endpoints (feeding, growth, avoidance, mucus secretion, locomotion and reproductive behavior) for the diagnosis of environmental pollution. The present review displays that all types of pollutants can disturb physiological and behavioral endpoints of gastropods, and these impacts depend on the matrix, exposure time and route as well as the type and concentration of the pollutants in the environment. We have also confirmed that terrestrial gastropods particularly snails as sentinel species could be used as potential bioindicator organisms for environmental quality assessment and thus for predicting potential hazards to human health.
人类活动造成的环境污染是一个全球性的公共卫生关注点。本综述讨论了不同类型的污染物，如农药、金属、纳米颗粒等，对陆地软体动物的影响。这些软体动物作为研究生态毒理学监测计划中生物标志物反应的良好模式生物，具有重要意义。几种生物标志物被用于表征和量化各种污染物的暴露和有害影响。在本综述中，我们确定了用于诊断环境污染的生理和行为终点（摄食、生长、回避、黏液分泌、运动和繁殖行为）。本综述表明，所有类型的污染物都可以干扰腹足类动物的生理和行为终点，这些影响取决于基质、暴露时间和途径以及环境中污染物的类型和浓度。我们还证实，陆地腹足类动物，特别是蜗牛作为指示物种，可以用作环境质量评估的潜在生物指标生物，从而预测对人类健康的潜在危害。
