The emerging of organotins (OTs) have adverse effect toward marine organisms and expose health problem through dietary uptake of contaminated seafood. While the booster biocide creates significant environmental risks mainly on the base of the marine food chain. The present study reported on the baseline data on the level and distribution of organotin and booster biocide in the primary producers (Ulva sp., Enhalus acoroides), mollusks (Strombus turturella, Perna viridis, Pinna nobilis) and fish species (Otolithus ruber, Polydactylus sextarius, Thryssa dussumieri) collected from the seagrass bed of Sungai Pulai estuary. The samples were extracted by mechanical shaking with acetone before analyses using GC–MS. The primary producers of Ulva sp. and Enhalus acoroides have the highest tributyltin (TBT) and mobobutyltin (MBT) concentration with values of 433 ± 22 and 35$\pm 1.8\mathrm{\mu }$g/kg, respectively. Meanwhile, mollusks and fish species have the highest monophenyltin (MPT) concentration which indicated phenyltin (PT) was dominant over butyltin (BT) compound. Dichlorofluanid and M1 are two compounds which mostly detectable in Polydactylus sextarius and Ulva sp. with the highest measured values of 130$\pm 3.7\mathrm{\mu }$g/kg and 86$\pm 4.3\mathrm{\mu }$g/kg, respectively. The elevated biocides detected in the selected marine organisms proved increasing application of these compounds in the shipping system, agricultural runoff, and domestic activities.

有机锡（OTs）的出现对海洋生物有不利影响，并通过饮食摄入被污染的海鲜而暴露出健康问题。加强杀菌剂主要在海洋食物链的基础上造成重大的环境风险。本研究报告了关于初级生产者（Ulva sp。，Enhalus acoroides），软体动物（Strrombus turturella，Perna viridis，Pinna nobilis）和鱼类（Otolithus ruber，Polydactylus）中有机锡和增强杀生物剂的水平和分布的基准数据。sextarius，赤鼻棱dussumieri）收集自双溪普莱河口海草床。在使用GC-MS进行分析之前，通过用丙酮进行机械振荡来提取样品。Ulva sp。的主要生产者。和Enhalus胶体中三丁基锡（TBT）和钼丁基锡（MBT）的浓度最高，分别为433±22和35$\pm \mathrm{1个}。8\mathrm{\mu }$g / kg。同时，软体动物和鱼类物种的单苯基锡（MPT）浓度最高，这表明苯基锡（PT）比丁基锡（BT）化合物占主导地位。Dichlorofluanid和M1是两种化合物，大多数可在六趾Poly和Ulva sp。中检测到。最高测量值为130$\pm 3。7\mathrm{\mu }$克/千克和86$\pm 4。3\mathrm{\mu }$g / kg。在选定的海洋生物中检测到的杀生物剂升高证明了这些化合物在运输系统，农业径流和家庭活动中的应用日益广泛。
