空投溴鼠灵毒饵防治岛上啮齿动物的措施已引起人们对环境污染及伤及非靶标生物的关注。本文概述了新西兰马翁盖特塔瑞岛围栏保护区内及小巴里尔岛、郎伊托托岛和莫图塔普岛等近海岛屿上害鼠防治后溴鼠灵残留的环境监测结果。马翁盖特塔瑞岛地区的淡水广泛取样及小巴里尔岛的淡水样本中都未检测到溴鼠灵。小巴里尔岛与毒饵接触的土壤样本中检测到残留,但100 d后,浓度降至接近探测的极限值。小巴里尔岛、郎伊托托岛和莫图塔普岛的海洋贝类中未检测到溴鼠灵残留。统计小巴里尔岛岛上包括几维鸟在内的一系列鸟类等非靶标动物的死亡率,投放毒饵后,在郎伊托托岛和莫图塔普岛海滨区域,9只死亡的小蓝企鹅中的3只体内有溴鼠灵残留,这些死亡可能是由毒饵的亚致死量摄入及饥饿造成的。结果显示了害鼠防治后环境监测的重要性,澄清了社会关注的溴鼠灵残留相关问题,并填补了溴鼠灵对环境的影响、留存时间及环境行为等信息的空白。
Measures to control rodents on the island by dropping bromopyrimidine bait have caused concern over environmental pollution and wounding of non-target organisms. This article provides an overview of the environmental monitoring of bromopyrimidine residues in pest protected areas on the Mahountai Island in New Zealand and on the coastal islands of Barbados, Langitoto Island and Motitapu Island in New Zealand. Bromhizole was undetectable in both the extensive sampling of freshwater in the Mahountai Tatal Island area and in the freshwater samples of the small Baltimore. Residues were detected in the soil samples contacted with the bait in small Baltimore, but after 100 days, the concentration dropped to near the limit of detection. No residues of bromopyrimidine were detected in the marine shellfish of Lesser Baltimore, Langtoto and Motitapu. Statistics on the mortality of non-target animals such as a series of birds on the Baltimore Island, including a few thousand birds, after the release of the bait, nine small dead in the Langitoto Island and Mototapu seashore areas Three of the blue penguins contained bromopyrimidine residues, which may be caused by the sublethal intake and starvation of the bait. The results showed the importance of environmental monitoring after the pest control and clarified the related problems of brodifacoum residues in society and filled the blank of the information about the environmental impact, retention time and environmental behavior of brodifacoum.
