The presence of booster biocides in the aquatic environment has been associated with a risk to non-target species due to their proven toxicity. The aim of the present study was to determine the spatial and temporal distribution of common booster biocides in different harbours of the island of Gran Canaria (Spain) and evaluate, by means of a probabilistic risk assessment (PRA), the ecological risk posed by these compounds. With these objectives, a monitoring campaign was conducted between January 2008 and May 2009, collecting a total of 182 seawater samples. Four common booster biocides (TCMTB, diuron, Irgarol 1051 and dichlofluanid) were monitored. Diuron levels ranged between 2.3 and 203 ng/L and Irgarol 1051 between 2.4 and 146.5 ng/L. The ecological risk associated with these levels was always low, however, with probabilities of exceeding the 10th percentile of autotroph toxicity below 3.5%.
在水生环境中存在增效型杀生剂，由于其已证实的毒性，会对非目标物种构成风险。本研究的目的是确定西班牙大加那利岛不同港口常见增效型杀生剂的时空分布，并通过概率风险评估（PRA）评估这些化合物造成的生态风险。为此目的，于 2008 年 1 月至 2009 年 5 月进行了一项监测活动，共采集了 182 个海水样本。监测了四种常见的增效型杀生剂（TCMTB、敌草隆、IRGAROL 1051 和双氯芬酸）。敌草隆的浓度范围在 2.3 到 203ng/L 之间，IRGAROL 1051 的浓度范围在 2.4 到 146.5ng/L 之间。这些浓度相关的生态风险始终较低，但是，自养生物毒性第 10 个百分位数超过的概率低于 3.5%。
