It is a widely held belief that environmental contaminants contribute to the decline of amphibian populations. By spending most of their early life in water and later stages on the land, amphibians face a constant risk of exposure to pesticides and other chemical pollutants in both aquatic and terrestrial environments. This review presents an overview of the studies carried out in Italian amphibians to highlight hazardous effects of bioaccumulation of chemical pollutants in juveniles and adults in various contaminated environments. Further, the studies in the laboratory setting assessing the effects of chemical pollutants on reproductive and developmental processes are reported. These studies and their relative references have been summarized in a tabular form. Three prominent contaminant groups were identified: herbicides, insecticides, and fungicides; and only a few works reported the effects of other chemical pollutants. Each pollutant group has been delegated to a section. All through the literature survey, it is seen that interest in this topic in Italy is very recent and sparse, where only a few anuran and caudata species and only some chemical pollutants have been studied.
人们普遍认为，环境污染物是造成两栖动物种群减少的原因之一。由于两栖动物在其早期生活中大部分时间都在水中度过，而在后期则在陆地上生活，因此它们面临着在水生和陆地环境中持续暴露于农药和其他化学污染物的风险。本综述介绍了在意大利两栖动物中进行的研究，以强调在各种受污染环境中，化学污染物在幼年和成年个体中的生物积累对其产生的有害影响。此外，还报告了在实验室环境中评估化学污染物对生殖和发育过程影响的研究。这些研究及其相关参考文献以表格形式进行了总结。确定了三类主要污染物：除草剂、杀虫剂和杀真菌剂；只有少数研究报告了其他化学污染物的影响。每个污染物组都被分配到一个部分。纵观整个文献调查，人们可以看到意大利对这一课题的兴趣非常新且稀少，仅对少数几种无尾目和有尾目物种以及一些化学污染物进行了研究。
