Item Concentration and Distribution of Heavy Metals Pb, Cu and Zn in Seawater, Sediment and Snail Telescopium telescopium Around Shipyards in Batam(2016-03-22) Amin, Bintal; Nurrachmi, Irvina; Kennedy, LeoA study on the concentration and distribution of heavy metals Pb, Cu and Zn in seawater, sediment and Snail Telescopium telescopium from coastal waters around shipyards in Batam has been conducted. Samples were taken from four stations and heavy metal analysis was carried out by using AAS Perkin Elmer 3110 in Marine Chemistry Laboratory Faculty of Fisheries and Marine Science University of Riau. The mean concentrations of Pb, Cu and Zn were 0.424; 0.057; 0.057 mg/L in seawater, 45.392; 129.688; 181.325 μg/g in sediment and 49.271; 87.663; 138.900 μg/g in T. telescopium, respectively. Higher concentration of Pb in T. telescopium than in sediment and seawater was found, whereas Cu and Zn were higher in sediment than in snail and seawater. Concentrations of Pb, Cu and Zn in seawater were possitively correlated with those in both sediment and snail and concentrations of those metals in sediment were also possitively correlated with those in snail. In general, the concentrations of Pb, Cu and Zn in coastal water around shipyard in Batam was higher than in coastal waters with no shipyard industry and they were still generally comparable to those reported values in regional studies. Mean concentration of Pb in sediment was nearly reach the ERL values whereas Cu and Zn already exceeded the ERL but still lower than ERM values. Continuous environment monitoring programs should be implemented.in Batam coastal waters since rapid developments in many infrastructure and industry sectors is taking placeItem Heavy Metals In Edible Intertidal Molluscs From The Middle East Coast Of Sumatera In Regard Of Its Distribution And Safe Human Consumption(2016-04-02) Amin, Bintal; Nurrachmi, Irvina; Zulkifli; Abdi, Septian JanuarDetermination of Pb, Cu and Zn concentrations in the soft tissues of edible intertidal molluscs collected from six locations in the midle east coast of Sumatera has been carried out in order to evaluate its concentration, pollution level and safe limit for human consumption. Heavy metals content analysis was carried out by using AAS Perkin Elmer 3110 in Marine Chemistry Laboratory Faculty of Fisheries and Marine Science, University of Riau. The results of the study showed that samples collected from the station with more anthropogenic and industrial activities exhibited higher concentration of metals than those from areas with less anthropogenic activities. The lowest metal concentrations were detected in Anadara granosa from Karimun waters whilst the highest concentrations were found in Strombus canarium from Batam waters. The PTWI limits would only be reached when people consumed more than 4.893; 4.590 dan 5.071 kg /week of blood cockle from Bagansiapiapi, Asahan and Karimun and 1.302 and 3.092 kg/week for Strombus canarium from Batam and Geloina coaxan from Selat Panjang waters respectively. Therefore the consumption of blood cockle from those areas was considered to be safe and there would be no risk for human consumption.
