Heavy metal contaminants in fish are of particular interest because of the potential risk to humans who consume them. The edible muscles of eight different species of fishes were analyzed by ICP-MS (Inductively Coupled Plasma Mass Spectroscopy) for heavy metals, collected from Market in Gwangju, Korea during April-May in 2008. The concentrations of Hg, As, Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn varied between 0.24±0.007 - 0.01±0.001, 44.54±5.69 - 1.23±0.20, 0.13±0.05 – ND (not detected), 1.32±0.47 - 0.09± 0.02, 3.13±2.53 - 0.63±0.06, 107.17±28.02 - 11.27±1.56, 12.38±1.23 - 0.25±0.02, 1.025±1.41 - 0.12±0.09, 0.74±0.28 - 0.05±0.03 and 80.30±17.09 - 22.35±6.89 mg/kg, respectively. The concentrations of arsenic and nickel exceeded the maximum allowable intake level. Keywords: Heavy metals; Marine fish; Korea. © 2010 JSR Publications. ISSN: 2070-0237 (Print); 2070-0245 (Online).

In this study, the level of arsenic (As), lead (Pb) and cadmium (Cd) and also essential elements in beer samples consumed in Turkey were investigated using the inductively coupled plasma mass spectrometry (ICP-MS) method. The heavy metal-induced non-carcinogenic and carcinogenic risks were calculated. For essential elements, the calculated estimated daily intake of iron (Fe), copper (Cu), selenium (Se) and cobalt (Co) from beer consumption were compared with their toxicity reference values. Tukey post-hoc test showed that As was found at a significantly higher level when compared to Pb. Also, a significant correlation was found between As level and alcohol by volume percent. All samples had a hazard quotient and hazard index <1, indicating no non-carcinogenic risk from exposure to single or multiple heavy metals. Some samples exceeded the threshold limit of acceptable cancer risk for As in the high beer consumer group. This assessment showed that in addition to health implications based on the alcohol content of beer, there might be a carcinogenic risk associated with the heavy metals content of these beverages.

Waste wood collected at the Vancouver landfill has been sorted based on the visibility of coatings, paints, and the green colorization of wood typically associated with wood preservatives. The sorted material was then ground and tested with an inductively coupled plasma mass spectrometry (ICP–MS) for heavy metal elements that are toxic or harmful to humans and (or) the environment. Results indicated that wood preservatives were not visually detectable but paints and coatings were. Therefore, the study demonstrated that visual sorting is not sufficiently accurate to distinguish between treated and clean or untreated waste wood.

The substantial of mineral ingredients in honey may symbolize the existence of elements in the plants and soil of the vicinity wherein the honey was taken. The aim of this study was to detect the levels of 13 elements (Potassium (K), Sodium (Na), Calcium (Ca), Iron (Fe), Zinc (Zn), Cadmium (Cd), Copper (Cu), Manganese (Mn), Lead (Pb), Nickel (Ni), Chromium (Cr), Aluminum (Al), and Selenium (Se)) in unifloral and multifloral honey samples from south and east regions of Turkey. Survey of 71 honey samples from seven different herbal origins, picked up from the south and east region of Turkey, was carried out to determine their mineral contents during 2015-2016. The mineral contents were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). The most abundant minerals were K, Na, and Ca ranging within 1.18–268 ppm, 0.57–13.1 ppm, and 0.77–4.5 ppm, respectively. Zn and Cu were the most abundant trace element while Pb, Cd, Ni, and Cr were the lowest heavy metals in the honey samples surveyed, with regard to the concentrations of heavy metals such as Zn, Cu, Pb, Cd, Ni, and Cr suggested and influence of the botanical origin of element composition. Geochemical and geographical differences are probably related to the variations of the chemical components of honey samples.

This study aimed to evaluate the capacity of Saccharomyces cerevisiae for Cadmium absorption in Milk. Nowadays one of the most serious problems is heavy metals pollution. Applying microorgaisms as a novel biotechnology is so useful especially in foodstuffs. Among the biosorbents for heavy metals&rsquo; removal, Saccharomyces cerevisiae has got an increasing attention due to its popularity in food industry. In this regard, the effects of some important factors such as the initial metal concentration, biomass concentration and contact time on the biosorption capacity of Saccharomyces cerevisiae were studied. The biosorption was analyzed by the inductively coupled plasma mass spectrometer (ICP-MS). The maximum Cd bioremoval (70%) was at 80 &mu;g/L of this metal concentration in milk samples containing 30&times;108 CFU Saccharomyces cerevisiae at the end of storage time (the 4th day). There were no significant differences in sensory and physicochemical properties of milk samples during storage (p &lt; 0.05). The isotherm studies followed by two popular models; Langmuir and Freundlich and the results showed a better fit to the Langmuir isotherm. All together, the results of this project demonstrated that the approach of using this valuable yeast, could be applied for food and drinks&rsquo; detoxification and producing healthier foods.

Heavy metal contaminations in aquatic habitats effect negatively on the organisms that depend on the water. In this work heavy metal levels in edible tissues of Cyprinus carpio from Karasu Stream in Sinop in summer, autumn and winter were determined by Inductively Coupled Plasma Mass Spectrometer. The accumulation pattern in the work is in the order of Zn>Cu>Pb>Cd> Hg. The amounts of Hg, Cd, Pb, Cu and Zn in carps were 0.022-0.036, 0.031-0.045, 0.22-0.29, 1.32-1.61 and 8.4-12.3 mg kg-1 wet wt., respectively. Concentrations of heavy metals in C. carpio were all below the TFC and EC guidelines. Total target hazard quotient (TTHQ) was 0.10722 and below 1 which showed that consumption of carp from the Karasu Stream has no health threats by now as the heavy metals investigated was concerned.

Logam berat merupakan variabel penting dalam penelaahan keamanan produk kekerangan. Namun, kuantifikasinya membutuhkan tingkat kesiapan analis dan peralatan laboratorium yang modern. Hal ini mendorong usulan berbagai metode penapisan High-throughput Screening seperti komposisi asam amino, sebagai penanda kimia pada penapisan tahap awal dari kontaminasi logam berat di biota kekerangan. Penelitian ini bertujuan untuk mengetahui fisibilitas komposisi asam amino yang terkandung pada produk kekerangan, sebagai penanda kimia akumulasi logam berat. Biota kerang bernilai ekonomis, yaitu kerang hijau (Perna viridis), dipilih sebagai target yang diambil dari tiga lokasi budidaya di Perairan Cirebon (sisi utara, perairan kota, dan sisi timur). Kadar logam berat (Cr, Co, Cu, As, Cd, Hg, dan Pb) dianalisis mempergunakan ICP-MS (Inductively Coupled Plasma-Mass Spectrometry), sementara kandungan asam amino ditelaah dengan kromatografi gas yang dilengkapi Flame Ionization Detector (FID). Hasil pengujian memperlihatkan bahwa kadar tertinggi dari tiap logam berat pada P. viridis adalah 0,25 mg/kg (Cr); 0,2 mg/kg (Co); 2,1 mg/kg (Cu); 1,5 mg/kg (As); 0,25 mg/kg (Cd); 0,25 mg/kg (Hg); dan 0,1 mg/kg (Pb). Nilai ini masih memenuhi persyaratan baku mutu, kecuali kadar arsen. Pengujian statistika korespondensi menunjukkan bahwa kadar asam amino kerang hijau dapat mengalami pergeseran komposisi yang tergantung pada tipe, variasi, dan kuantifikasi akumulasi logam beratnya. Oleh karena itu, tidak ada satupun jenis asam amino tertentu yang dapat dijadikan sebagai penanda kimia umum dari akumulasi berbagai jenis logam berat. Penelitian lebih lanjut dapat dilakukan untuk menemukan faktor pembanding menggunakan senyawa tertentu yang dapat melengkapi rasio komposisi asam amino sebagai penanda kimia dari akumulasi logam berat pada biota kekerangan.ABSTRACTHeavy metals are important factor in the food safety analysis of marine mussels. However, heavy metal quantification requires factors an adequate analyst and modern laboratory equipment. Therefore, various high throughput screening methods have been proposed, such as the composition of amino acids as a marker in a preliminary screening of heavy metal contamination in marine mussels. This study aimed to determine the feasibility of amino acids composition in marine mussels as a chemical marker of heavy metal accumulation. The commercial marine mussels, Green Mussels (Perna viridis), were collected from three aquaculture sites in Cirebon Waters (north side, in front of the city, and east side). Heavy metals content (Cr, Co, Cu, As, Cd, Hg, and Pb) was analyzed by ICP-MS (Inductively Coupled Plasma-Mass Spectrometry) technique while the amino acids content was analyzed using gas chromatography with Flame Ionization Detector (FID). Results of this study showed that the maximum value of each heavy metal in P. viridis were 0.25 mg/kg (Cr); 0.2 mg/kg (Co); 2.1 mg/kg (Cu); 1.5 mg/kg (As); 0.25 mg/kg (Cd); 0.25 mg/kg (Hg); and 0.1 mg/kg (Pb). Except for arsenic, these values were below the allowable threshold level. Correspondence analysis showed that the composition of amino acids in the green mussels was shifted, according to the type, variation, and quantification of the accumulated heavy metals. Therefore, none of the amino acids can be used as a general chemical marker for various types of heavy metals. Further research can be done to identify a particular comparative compound that can complement the ratio of amino acids composition as biomarkers for heavy metals accumulation in marine mussels.
