摘要

绿贻贝(Perna viridis)作为一种定居生物,在海洋环境中被用作生物指示物已有几十年的历史。它们可能受到人为活动和水生环境中多环芳烃(PAHs)等有机污染物的影响。本研究旨在确定雅加达湾Cilincing水域青贻贝生物量中多环芳烃的浓度、分布和潜在来源。从雅加达湾Cilincing水域的水产养殖设施中采集不同大小、不同壳长的新鲜青贻贝,用溶剂正己烷-二氯甲烷混合物采用索氏法提取。用硅胶/无水硫酸钠与正戊烯- dcm出水分馏提纯样品萃取物浓缩液。最后,将纯化后的样品注入气相色谱-质谱仪。结果表明,总多环芳烃(TPAH)的最高浓度为126.47 ng。最大群青贻贝(长度为6.00 ~ 7.99 cm)内脏中G-1的湿重(ww)和3-芳香环在各大群青贻贝中均有显著分布。LMW/ HMW和诊断二元比结果表明,多环芳烃污染是由产岩和热生混合源引起的。这可能是由于来自船厂和货物活动以及大气沉积的溢油和石油废物的存在。根据美国国家药品和食品管理局(BPOM)规定的过量致癌风险(ECR)值和多环芳烃致癌物浓度水平,绿贻贝中的多环芳烃水平是可以接受的,并且由于典型的人类食用而产生的负面影响很小。然而,由于青贻贝的致癌性,将其开发为日常食用的海鲜资源需要谨慎。

Occurrence and Source Apportionment of Polycyclic Aromatic Hydrocarbons (PAHs) in Green Mussel (Perna viridis) from Cilincing Waters of Jakarta Bay, Indonesia
Green mussels (Perna viridis) as sedentary organisms have been adopted as bioindicators in the marine environment for many decades. They have been potentially affected by anthropogenic activity and organic contaminants such as polycyclic aromatic hydrocarbons (PAHs) in an aquatic environment. This study aims to determine concentration, distribution and potential sources of PAHs in green mussel biomass obtained from Cilincing waters, Jakarta Bay. Fresh green mussels were collected from aquaculture facilities at Cilincing waters of Jakarta Bay with various size categories of shell length and were extracted with solvent n-hexane-dichloromethane mixture using Soxhlet method. The concentrate of sample extract was purified using silica gel/sodium sulfate anhydrous with n-pentene-DCM effluent in fractionation. Finally, the purified sample was injected into the GC-MS instrument. The result showed that the highest concentration of total PAH (TPAH) was 126.47 ng.g-1 wet weight (ww), founded in the guts from the biggest group of green mussel (length of 6.00 to 7.99 cm), and     3-aromatic rings were predominantly detected in all group sizes of green mussel. The result of the   LMW/  HMW and diagnostic binary ratio indicated that PAH contamination is caused by a mixed source of petrogenic and pyrogenic processes. It may be due to the presence of oil spilled and petroleum waste from shipyard and cargo activities and atmospheric deposition. Based on excess cancer risk (ECR) value and the concentration level of PAH carcinogenic according to National Agency of Drug and Food Control (BPOM) regulation, PAH level in green mussels are acceptable and minor negative impact due to typical human consumption. Nevertheless, it needs to be circumspect to exploiting green mussels as seafood resources for daily consumption due to the carcinogenic content.
