In the Maldivian islands, the lack of sewage wastewater treatment and an improper landfill enhance the potential hazard of emerging contaminants, including pharmaceuticals and personal care products. In order to analyze the occurrence of emerging contaminants in the marine biota, sponges were collected in two coral reef areas of Magoodhoo island (Faafu), one near the landfill and the other furthest from the island. Caffeine, fluoxetine and norfluoxetine were detected only in the proximity of the landfill, with caffeine showing the highest concentration (28.4 ng/g d.w.), followed by fluoxetine (6.00 ng/g d.w.). Norfluoxetine was below the limit of quantification of 10 ng/g d.w. Nitro xylene, N,N-Diethyl-meta-toluamide and galaxolide were found in both areas, with concentrations of 3.51/6.11/8.54 and <LOQ/1.14/0.62 ng/g d.w., respectively. Due to the vital role of the coral reef for the livelihood and economy of the Maldivian people, attention should be paid to this class of contaminant.

马尔代夫一个有人居住的岛屿的海绵中出现的污染物的首次记录。

在马尔代夫群岛,缺乏污水处理和不适当的垃圾掩埋加剧了新兴污染物(包括药品和个人护理产品)的潜在危害。为了分析海洋生物区系中新出现的污染物的发生,在马古德霍岛(Faafu)的两个珊瑚礁区域中收集了海绵,一个靠近垃圾填埋场,另一个离该岛最远。仅在垃圾填埋场附近检测到咖啡因,氟西汀和去氟西汀,其中咖啡因的浓度最高(28.4 ng / g dw),其次是氟西汀(6.00 ng / g dw)。诺氟西汀低于10 ng / g dw的定量下限硝基二甲苯,N,N-二乙基-间甲酰胺和加拉索利特均在两个区域中发现,浓度为3.51 / 6.11 / 8.54和<LOQ / 1.14 / 0.62 ng / g dw分别。
