Growth of the aquaculture industry has triggered the need for research into the potential environmental impact of chemicals used by salmon farms to control diseases. In this study, the antiparasitic pesticides emamectin benzoate (EB), diflubenzuron (DI), teflubenzuron (TE), and cypermethrin (CP) were measured in sediments near salmon cages in southern Chile. Concentrations for EB were between 2.2 and 14.6ngg, while the benzoylphenyl ureas DI and TE were detected in the ranges of 0.1 to 1.2ngg and 0.8 to 123.3ngg, respectively. These results were similar to data reported for the Northern Hemisphere. On the other hand, the pyrethroid CP was detected in higher concentrations, ranging from 18.0 to 1323.7ngg. According to reported toxicity data, this range represents a potential risk for benthic invertebrates. This report is the first baseline attempt at assessing antiparasitic pesticide levels in the Chilean Patagonia.
水产养殖业的发展引发了人们对用于控制疾病的鲑鱼养殖场化学物质的潜在环境影响的研究。在这项研究中,在智利南部的鲑鱼笼附近的沉积物中测量了抗寄生虫农药甲氨基阿维菌素苯甲酸盐(EB)、氟苯脲(DI)、氟虫脲(TE)和氯菊酯(CP)。EB 的浓度在 2.2 到 14.6ngg 之间,而苯甲酰基苯基脲 DI 和 TE 的检测范围分别为 0.1 到 1.2ngg 和 0.8 到 123.3ngg。这些结果与北半球的数据相似。另一方面,拟除虫菊酯 CP 的浓度更高,范围从 18.0 到 1323.7ngg。根据报告的毒性数据,这一范围代表了底栖无脊椎动物的潜在风险。本报告是首次尝试评估智利巴塔哥尼亚地区抗寄生虫农药的水平。
