Abstract

Playa Penino is a natural reserve located on the south coast of Uruguay. It hosts 244 species of birds (more than 50% of the bird biodiversity recorded for Uruguay). The area is included in the International BirdLife Program for biodiversity preservation. Urbanization and pollution generally have affected the quality of the water and biodiversity in wetlands. The analysis of the major wetland of Playa Penino revealed high levels of organic compounds. The biomonitoring was done using the caviomorph rodent Ctenomys pearsoni (commonly known as tuco tuco) as an indicator species because they inhabit burrows around the wetland. Genetic effects were determined using the comet assay and micronucleus test. The significant correlations between chemical and microbiological parameters and genetic damage might indicate that macronutrients from sewage could be one of the causes of the genetic damage. There is an urgent need to conserve the biodiversity of this natural area by introducing sewage treatment, cesspool control and by controlling settlement in the area etc.
生物标志物作为评估沿海湿地扩散污染的工具
佩尼诺海滩是位于乌拉圭南海岸的一个自然保护区。它拥有244种鸟类(占乌拉圭鸟类生物多样性记录的50%以上)。该地区被列入国际鸟盟生物多样性保护计划。城市化和污染普遍影响了湿地的水质和生物多样性。对普拉亚佩尼诺主要湿地的分析显示,有机化合物含量很高。生物监测是使用洞穴形态啮齿动物Ctenomys pearsoni(俗称tuco-tuco)作为指示物种进行的,因为它们栖息在湿地周围的洞穴中。使用彗星试验和微核试验测定遗传效应。化学和微生物参数与遗传损伤之间的显著相关性可能表明,污水中的大量营养物质可能是遗传损伤的原因之一。迫切需要通过引入污水处理、污水池控制和控制该地区的定居点等措施来保护该自然区域的生物多样性。

期刊介绍: The European Journal of Environmental Sciences offers a mixture of original refereed research papers, which bring you some of the most exciting developments in environmental sciences in the broadest sense, often with an inter- or trans-disciplinary perspective, focused on the European problems. The journal also includes critical reviews on topical issues, and overviews of the status of environmental protection in particular regions / countries. The journal covers a broad range of topics, including direct or indirect interactions between abiotic or biotic components of the environment, interactions of environment with human society, etc. The journal is published twice a year (June, December).
