“…Moreover, the percentages of metals were significantly different (p < 0.05) in the soft tissues of clams from different sites. The results were in agreement with previous reports on the composition patterns of heavy metals in aquatic organisms (Sankar et al, 2006;Mitra et al, 2012;Tao et al, 2012), such as fish and shellfish. Because essential elements have an important role in the growth and development, immunity, reproduction, and other functions, aquatic organisms tend to accumulate relatively high levels of essential elements for normal life activities, but very high levels of the essential mineral elements will be harmful to the health of aquatic organisms and human beings (Gale et al, 2004).…”

a b s t r a c tTo investigate the pollution level and evaluate the potential health risks of heavy metals, the concentrations of chromium (Cr), manganese (Mn), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), selenium (Se), molybdenum (Mo), cadmium (Cd), antimony (Sb), and lead (Pb) were determined by inductively coupled plasma-mass spectrometry (ICP-MS) in 198 clams (Mactra veneriformis) collected from 11 sites of the Bohai Bay. The results showed that heavy metal concentrations in the clams were different at different sites (p < 0.05). Mn was dominant with a percentage of 22.08-77.03% in heavy metals, followed by Zn with 12.66-57.11%, and the concentration of Pb was the lowest with 0.45-1.04%. The potential health risk to consumers was evaluated by the target hazard quotient (THQ) and the maximum daily consumption rate (CR max ). The results indicated that the THQs of Co were the highest with the values of 1.125, 1.665, and 1.144 at three sections; the values of other individual metals were <1, which indicated that consumption of clams from the study areas caused health risks due to Co. Moreover, the CR max values also indicated the potential health risk caused by Co in clams consumed in this area. Pearson correlation analysis and principal component analysis (PCA) indicated that there were significantly positive or negative correlations between the heavy metals (p < 0.05), and the studied metals were divided into four groups. The results indicated that the concentrations of heavy metals in clams were affected not only by pollution sources but also by the characteristics of clams that could absorb selectively and accumulate special metals. This study offers important information on the pollution levels of heavy metals in clams and warns consumers of the health risks associated with the consumption of clams in the area.

“…The findings of the present study are in a good agreement with the observation of Sankar et al (2006). They have collected fish from five different locations from the Caligut region, India and analyzed for the quantification of organochlorine (OC) insecticides and heavy metal (HM) residues.…”

Determination of organochlorine pesticide residues in shrimp is very important to ensure the consumer's safety and to fulfill the importer's demand. Therefore, a simple and efficient multiple organochlorine pesticide residues analytical method using quick, easy, cheap, effective, rugged and safe (QuEChERS) extraction technique and Gas Chromatography coupled with Electron Capture Detector (ECD) has been developed and validated for the determination of 19 organochlorine pesticides (α-BHC, δ-BHC, β-BHC, γ-BHC, Heptachlor, Aldrin, Heptachlor Epoxide, γ-Chlordane, α-Chlordane, α-Endosulfan, 4,4 DDE, Dieldrin, Endrin, 4,4 DDD, β-Endosulfan, 4,4 DDT, Endosulfan sulphate, Methoxychlor, and Endrin Ketone) in shrimp. The method was validated by evaluating the accuracy, precision, linearity, limit of detection (LOD) and limit of quantification (LOQ). The average recoveries of the selected pesticides ranged from 84% to 106% with RSDr ≤ 14% in four fortification levels of 0.05, 0.1, 0.2 and 0.3 mg kg . This method was applied successfully for the residue analysis of 40 shrimp samples collected from different regions in Bangladesh.

“…According to the currently accepted guidelines, in order to protect human consumers, edible portions of molluscs should not exceed 80.0 mg Ni/kg wet weight (w.w.) (USFDA 2001;Sankar et al 2006). From Table 5, it is evident that Ni concentrations in Noah's Ark shellfish from this study were considerably lower than this limit.…”

Commercially important bivalve Noah's Ark shell (Arca noae Linnaeus, 1758) represents a high-quality seafood product, but the data on levels of metal contaminants that could pose a human health risk and also on some essential elements that are important for health protection are lacking. This study examineds the concentrations of Cd, Pb, Cr, Ni, Cu, Co, and Zn in the mg/kg wet weight. These levels were lower than the permissible limits for safe consummation of seafood, and only for Cd, some precautions should be taken into account if older shellfish were consumed. Increase of Cd, Cr, and Cu in shell tissue was observed during the tourist season at the site closest to the marine traffic routes, indicating that metal levels in shellfish tissue should be monitored especially carefully monitored during the peak tourist season, to prevent eventual toxic effects due to increased intake of metals, specifically of Cd.
