Abstract

Magrove crab S cylla s errata lives in coastal area of city is susceptible to contaminate by heavy metals. Therefore, the objective of the present study was to examine the heavymetalcontentofLead (Pb)andCadmium(Cd)inmangrovecrab S . s errata obtained from several traditional markets in the Medancity, Indonesia. The measurementofheavymetalcontentwascarriedoutusingtheAtomicAbsorption SpectrophotometerwiththeFurnaceGraphmethod.The samples were collected from six marketsin Medan city i.e. Pancing, Sei Kambing, Petisah, Belawan, Jamin Ginting and Padang Bulan markets. Thereresultsshowed that the highestvalueofPbinwas in samplefrom Pancing (0.025mg kg -1 )and Sei Sikambing (0.025mg kg -1 ) Markets and lower was found in sample from Belawan market (0.013mg kg -1 ). In addition, the highestCadmium(Cd)contentisinPancing Market (0.023 mg kg -1 ) and lower Cd was from Belawan Market (0.101mg kg -1 ). It was concluded that heavymetalsPbandCdineachsampleofmangrove crabswereclassifiedaslow level andstill met thequality standard threshold.

印度尼西亚棉兰市几个传统市场采集的红树蟹Scylla serrata的铅和镉含量

生活在城市沿海地区的梭子蟹易受重金属污染。因此，本研究的目的是检测红树蟹中重金属铅(Pb)和镉(Cd)的含量。该勘误表来自印度尼西亚Medancity的几个传统市场。采用原子吸收分光光度法和炉图法测定重金属含量。样本来自棉兰市的6个市场，即Pancing、Sei Kambing、Petisah、Belawan、Jamin Ginting和Padang Bulan市场。结果表明，pbin的含量最高的是潘宁市(0.025mg kg -1)和塞西坎宾市(0.025mg kg -1)，较低的是贝拉湾市(0.013mg kg -1)。此外，黄浦江市场镉含量最高(0.023 mg kg -1)，卑拉湾市场镉含量较低(0.101mg kg -1)。结果表明，各样品的重金属含量均处于较低水平，仍符合质量标准阈值。因此,themangrovecrabsampleisstillsafeforconsumptionand canbeanexportcommodity。关键词:红树林蟹，重金属，污染，原子吸收光谱法
