Illicit drugs and their metabolites represent a new class of emerging contaminants. These substances are continuously discharged into wastewater which have been detected in the aquatic environment in concentrations ranging from ng.L to μg.L. Our study detected the occurrence of cocaine (COC) and benzoylecgonine (BE) in a subtropical coastal zone (Santos Bay, SP, Brazil) within one year. Water samples (surface and bottom) were collected from the Santos Submarine Sewage Outfall (SSOS) area. COC and BE were measured in the samples using ultra-performance liquid chromatography coupled to tandem mass spectrometry (UPLC-ESI-MS/MS). Concentrations ranged from 12.18 to 203.6 ng.L (COC) and 8.20 to 38.59 ng.L (BE). Higher concentrations of COC were observed during the end of spring, following the population increase at summer season. COC and its metabolite occurrence in this coastal zone represent a threat to coastal organisms.
非法药物及其代谢物是新出现的一类污染物。这些物质不断被排放到废水中，已在水环境中检测到其浓度范围在 ng.L 到 μg.L 之间。我们的研究在一年内检测到了可卡因（COC）和苯甲酰爱康宁（BE）在亚热带沿海地区（巴西桑托斯湾）的存在。从桑托斯海底污水排放口（SSOS）地区采集了水样（地表水和底水）。使用超高效液相色谱-串联质谱法（UPLC-ESI-MS/MS）对样品中的 COC 和 BE 进行了测量。浓度范围为 12.18 到 203.6ng.L（COC）和 8.20 到 38.59ng.L（BE）。在春季末期，随着夏季人口的增加，观察到 COC 浓度更高。在这个沿海地区出现 COC 和其代谢物对沿海生物构成了威胁。
