Abstract

The waters of Sedanau, Natuna Regency are congested with traffic activities of inter-island transport ships and the construction of docks that have the potential to cause pollution to the aquatic environment. Determination of the levels of heavy metals (Pb) and (Cd) in feather shells (Anadara antiquata) in these waters has been carried out. The purpose of this study was to determine the concentration of heavy metals Pb, Cd in feather shells (Anadara antiquata) which was carried out for 2 time periods, 2020 and 2021 at 2 different sampling stations. Station 1 is close to fishing activities, fishing boat traffic docks and inter-island passenger ships, station 2 is close to fishing boat docks and floating net cages but far from fishing activities and ship traffic. Measurement of the concentration of heavy metals Pb and Cd using the Atomic Absorption Spectrophotometer (SSA) method with reference to the Indonesian National Standard (SNI) Number 06-6992.2-2004 heavy metals Pb and Cd in feather shells (Anadara antiquata). The results of the measurement of heavy metal concentrations of Pb and Cd in feather shells (Anadara antiquata) in the first year were the content of (Cd) at station 1 of 0.0214 g/g, station 2 of 0.0236 g/g and (Pb) of station 1 of 0. 0.0109 g/g, station 2 was not detected, while in the second year the content (Cd) of station 1 was 1.3472 g/g, station 2 was 0.9980 g/g and (Pb) stations 1 and 2 were not detected. heavy metal content. Measurements in the second year of heavy metal content of Pb and Cd were lower than in the first year which had exceeded the threshold allowed in the Indonesian National Standard (SNI) No. 7387 of 2009 concerning the Maximum Limit of Heavy Metal Contamination in Food Lead (Pb) 1.5 mg/kg and Cadmium (Cd) 1.0 mg/kg

纳土纳摄政的雪丹瑙水域因岛屿间运输船的交通活动和码头的建设而拥挤不堪，这有可能对水生环境造成污染。对这些水域的羽壳(Anadara antiquata)中重金属(Pb)和(Cd)的含量进行了测定。本研究的目的是测定羽毛壳(Anadara antiquata)中重金属Pb、Cd的浓度，该研究在2020年和2021年两个不同的采样站进行。站点1靠近捕鱼活动、渔船交通码头和岛际客船，站点2靠近渔船码头和浮网笼，但远离捕鱼活动和船舶交通。参考印尼国家标准(SNI)编号06-6992.2-2004，用原子吸收分光光度计(SSA)法测定羽毛壳(Anadara antiquata)中重金属Pb和Cd的浓度。对羽壳(Anadara antiquata)第一年重金属Pb、Cd含量的测定结果为:(Cd) 1站为0.0214 g/g， (Cd) 2站为0.0236 g/g， (Pb) 1站为0。0.0109 g/g, 2号站未检出，第二年1号站(Cd)含量为1.3472 g/g, 2号站(Cd)含量为0.9980 g/g, 1、2号站(Pb)未检出。重金属含量。第二年测得的铅、镉重金属含量低于第一年，已超过印尼国家标准(SNI) 2009年第7387号《食品中重金属污染最高限量铅(Pb) 1.5 mg/kg、镉(Cd) 1.0 mg/kg》规定的阈值
