The aims of this research are to analyze the content of Lead in blood cockle (Genus: Anadara) at West Lombok Labuhan Tereng coastal waters. The content of lead in sediment and clams was analysis at Mataram University Analytical Laboratory by using wet digestion method and measured using atomic absorption spectrophotometer (AAS) in 283.3 nm wavelength. The results then compared with the sediments and clams standards applicable. Results of Pb in the sediment measurements show that the highest lead levels is 30.66 mg/kg found in around Dusun Cemara coast. The results obtained are still at the level targets under Dutch Quality Standards for Metals in sediments (IADC / CEDA), 1997. The highest Pb levels in blood clams is 13,075 mg/kg contained by a medium-sized (3.08 cm) of species A. antiquata around Kebon Talo estuary. These results are indicate that the levels of Pb in blood cockle is already distant exceeded the threshold of consumption under Indonesian National Standar, 2009 which is equals to 1.5 mg/kg, so the clams blood in coastal waters Labuhan Tereng should not be consumed greatly overheated because the accumulative character of Pb can be harmful for health.Keywords: Blood cockle, sediment, acumulation, lead

Abstract Background Lead is a hazardous heavy metal, which causes many problems in the human body. Unfortunately, recent reports showed that smugglers and opium sellers add lead to drugs during the production procedure in order to increase its weight and cost. Purpose The aim of this study was development of a rapid and accurate method for measurement of blood lead levels (BLL) in the oral and inhaled opiate abuser people. Methods BLL in samples obtained from the oral and inhaled opium addicted patients referring to Sina Hospital in Tabriz, Iran, during 2017 was compared with healthy control group (N=15). The wet digestion method was used to prepare whole blood and Mercury Droplet Electrode Polarography (MDEP) method was utilized for measurement of the lead content of digested samples. Results Results showed that there were significant differences between the BLL of samples obtained from oral (17.12±74.61 μg/dL, p<0.0003) and inhaled (19.33±2.257 μg/dL, p<0.0001) opium addicted groups in comparison with healthy control group (4.669±0.3367 μg/dL). Conclusion Based on the results of this study it was observed that BLL in opium addicted people needs to be measured as soon as possible. Furthermore, screening of blood lead concentrations in opium-addicted people with a rapid and accurate MDEP method is very necessary and important.
