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.

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.

Background: Fish is a source of nutrition; however, toxic substances and heavy metals may enter human body due to consuming contaminated fish. The aim of this study was to investigate the levels of heavy metals and DDTs in Liza parsia, a fish species, and assess the health risk of the contaminants in the fish samples. Methods: The extracted fish lipid was added with n-hexane and H2SO4 and was kept for long time. The upper organic part was collected for the analysis of DDTs by gas chromatography equipped with electron capture detector. The fish samples were homogenized by wet digestion method, and the heavy metal contents were analyzed, using an atomic absorption spectrophotometer. The health risks of the fish samples were assessed based on target hazard quotient and target cancer risk. Results: The pesticide contents of DDT, DDD, DDE and DDTs in the fish samples were 0.0414, 0.000253, 0.015 and 0.0567ng/g, respectively. Also, the mean concentrations of Mn, Fe, Cu and Zn were 35.42±10.05, 318.75±242.45, 41.67±4.78 and 281.25±5.42 mg/kg, respectively. Of note, the Cd and Pb contents were below the detection limits. The concentrations of other heavy metals were above the reference limits, which can cause various disease processes. Conclusion: The contents of four heavy metals and DDTs in the samples were above the limits. The main sources of these substances are likely due to human anthropogenic activities. Fish and other edible aquatic animals should be monitored regularly and the heavy metal levels be determined and declared to the public.

AbstractThis study aimed to evaluate the exposure levels and variation in airborne endotoxin and heavy metals such as aluminum, chromium (Cr), iron (Fe), manganese (Mn), nickel (Ni), zinc, and lead (Pb) in the three different South Korean subway environments (driver room, station office, and underground tunnel) and identify subway characteristics influencing endotoxin and heavy metals levels. Air samples were collected and analyzed using the kinetic Limulus Amebocyte Lysate assay and inductively coupled plasma mass spectrometers. The geometric mean was determined for endotoxin levels (0.693 EU/m3). It was also found that Fe (5.070 µg/m3) had the highest levels in subway environments while Pb (0.008 µg/m3) had the lowest levels. Endotoxin levels were higher in the underground tunnel and lower in the station office; the total heavy metal levels showed the same pattern with endotoxin levels. Endotoxins and total heavy metal levels were higher in the morning than at night. Positive correlations were found between endotoxin and Cr, Fe, Mn, and Ni levels. Given the correlation between airborne endotoxins and heavy metals, further studies with larger sample sizes are needed to identify the correlation between levels of airborne endotoxin and heavy metals.

Abstract Contamination with heavy metals in wild red swamp crayfish (Procambarus clarkii) from 7 different geographical areas in six provinces of China (Hubei, Hunan, Jiangxi, Anhui, Jiangsu, and Shandong) was evaluated. Concentrations of chromium (Cr), arsenic (As), lead (Pb), cadmium (Cd), and mercury (Hg) in the abdominal muscle, gonad, and hepatopancreas were determined by inductively coupled plasma mass spectrometry (ICP-MS) and Atomic Fluorescence Spectrometer (AFS). Except for the Cd content in hepatopancreas, the contents of selected heavy metals in three different tissues were significantly lower than the proposed limits provided by United States Environmental Protection Agency (USEPA). The maximum accumulations of Cd and Pb were in hepatopancreas, while the maximum accumulation of As was in gonad, and the maximum accumulations of Hg and Cr were in abdominal muscle. The highest contents of Cr, Hg, and Pb were all detected in Dongting Lake, Hunan, which was consistent with the trend of the metal pollution index (MPI). Risk value of the target hazard quotient (THQ) was below 1.0, suggesting that the intake of selected heavy metals through crayfish consumption would not pose a significant health risk to consumers.

Fish is a major source of food in many parts of the world because they contribute to solving the global food problem and provide the well-known proteins, minerals, vitamin and trace elements content. Concentrations of iron (Fe), zinc (Zn), copper (Cu), nickel (Ni), lead (Pb) and cadmium (Cd) were determined in various parts of the fish (liver, gill, bone and muscle) of Mackerel (Scomber scombrus), Sardine (Sardinella longiceps), Hake (Merluccius merluccius) and Express (Platax scalaris) which were purchased from two major markets in Abeokuta, Ogun State, Nigeria. Heavy metal levels in the fish samples were analyzed by Atomic Absorption Spectrophotometer (AAS Buck 211). Health risks related to Fe, Zn, Cu, Ni, Pb and Cd were assessed based on target hazard quotient (THQ). Results obtained showed variations in the levels of heavy metals across the various tissues in the fish samples. The concentration of Fe was highest in all the tissues in the fish samples with the gill recording the highest level. There were higher concentrations of heavy metals in the gills than in other tissues of the fish samples. The trend of heavy metal levels in the tissues was found to be Fe > Zn > Cu > Ni > Pb > Cd. Highest levels of Pb and Cd in the muscle were 1.92 ± 0.04 and 0.64 ± 0.04 mg/kg in Merlucciusmerloccius and Scomberscombrus respectively. The concentrations of Pb and Cd were higher in the muscles of all the samples than European Community and Food and Agriculture Organization maximum permissible levels. The health risks from Ni and Pb were found highest among all the heavy metals in the fish samples. THQ values of Cu and Cd in Sardinellalongiceps and Cu in Merlucciusmerloccius were higher than 1. Health risk assessment of Ni and Pb in all the fish studied and Cd in Sardinellalongiceps indicates that their consumption may be unsafe.

The presented study was aimed at the determination of the level of contamination with heavy metals (Cd, Pb, As, and Hg) in 240 samples of plant materials, i.e., herbal raw materials, spices, tea, and coffee. Moreover, a probabilistic risk assessment (noncarcinogenic and carcinogenic risks) was estimated by models including target hazard quotient (THQ) and cancer risk (CR). The samples were subjected to microwave mineralisation with the use of HNO3 (65%), while the determination of the content of the elements was performed with the use of inductively coupled plasma mass spectrometer (ICP–MS) and a mercury analyser. The element which was characterised by the highest level of accumulation in the analysed samples was lead (from 0.010 to 5.680 mg/kg). Among the heavy metals under analysis, the lowest concentration was noted in the case of mercury (from 0.005 to 0.030 mg/kg). A notably higher level of contamination with heavy metals was noted in the analysed samples of herbs and spices (0.005–5.680 mg/kg), compared to samples of tea and coffee (0.005–0.791 mg/kg). According to the guidelines of the World Health Organisation (WHO) concerning the limits of contamination of samples of herbal raw materials with heavy metals, lead levels exceeding the limits were only noted in 24 samples of herbs (18%). In all of the analysed samples of spices, tea, and coffee, no instances of exceeded limits were noted for any of the analysed heavy metals. The values of TTHQmax (in relation to the consumption of the analysed products) were as follows: up to 4.23 × 10−2 for spices, up to 2.51 × 10−1 for herbs, up to 4.03 × 10−2 for China tea, and up to 1.25 × 10−1 for roasted coffee beans. As the value of THQ ≤1, there is no probability of the appearance of undesirable effects related to the consumption of the analysed group of raw materials and products of plant origin. The CR value for As (max. value) was 1.29 × 10−5, which is lower than the maximum acceptable level of 1 × 10−4 suggested by United States Environmental Protection Agency (USEPA).

Roadside soil, dusts, and three ornamental plants-Begoniaceae (Begonia semperflorens Link et Otto), Tagetes (Tagetes erecta Linn.), and Salvia (Salvia splendens Ker-Gawle) were collected from urban arteries in Nanjing City, China. Concentrations of metals (Pb, Cd, Cu and Zn) were analyzed using inductively coupled plasma atom emission spectrometry and inductively coupled plasma mass spectrometry. Cd was the most important contaminant in roadside soil and dusts. Generally, Begoniaceae accumulated more metals than Tagetes and Salvia. The order of bioconcentration factor values for three kinds of plants were Cd > Cu > Zn > Pb, suggesting Cd was more easily accumulated by ornamental plants than Zn and Pb from soils to roots. The values of the translocation factor show the significant species specific characteristics on the ability of metals (Cd, Cu, Zn and Pb) translocation from roots to leaves. Begoniaceae was recommended as a bioindicator of heavy metals in the urban environment.

Fruits could contain elements in various concentrations, which can have both positive and negative impacts on human health. The concentrations of essential elements, including Iron (Fe), Copper (Cu), Zinc (Zn), Manganese (Mn), and Chromium (Cr) in five types of fruits, namely, peach, apple, grape, nectarine, and golden plum, and the soil and irrigation water from six industrial zones of Markazi province, Iran, were evaluated using an inductively coupled plasma-optical emission spectroscopy (ICP-OES) technique. The noncarcinogenic risk was assessed by determining the target hazard quotient and the Monte Carlo simulation model. The highest concentrations of Fe, Mn, and Cr were observed in golden plum, while the highest concentrations of Cu and Zn were noted in grape and apple, respectively. The order of the mean of concentrations of elements in the soil and water samples were Fe > Mn > Zn > Cu > Cr. The transfer factor (TF) results indicate that studied fruits could not absorb a high amount of these elements from the soil (TF < 1). Target hazard quotient values of these elements in both adults and chil-dren were ranked as Cr > Cur > Fe > Mn > Zn. The target hazard quotient was 95% and total target hazard quo-tient was <1, meaning that the consumption of fruits is safe for consumers.

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.

This study estimated the concentrations of heavy metals in regularly consumed sour, sweet and homemade traditional yogurts in Bangladesh. A total of 300 yogurt samples (sour, sweet and homemade traditional); 100 yogurt samples of each category were considered for this assay. To assess the health risks, the daily yogurt consumption rate and the value of target carcinogenic and non-carcinogenic risks of these yogurt samples were also determined. In sour yogurt samples, detected heavy metal contents were 0.398±0.121 mg/kg, 0.774±0.372 mg/kg, 0.087±0.021 mg/kg, 0.131±0.026 mg/kg, 0.011±0.006 mg/kg, 0.031±0.005 mg/kg, 0.445±0.267 mg/kg and 0.029±0.024 mg/kg while in sweet yogurt samples, detected heavy metal contents were 0.410±0.146 mg/kg, 0.704±0.324 mg/kg, 0.082±0.028 mg/kg, 0.146±0.025 mg/kg, 0.010±0.005 mg/kg, 0.030±0.007 mg/kg, 0.460±0.265 mg/kg, and 0.035±0.026 mg/kg and in homemade traditional yogurt samples, detected heavy metal contents were 0.410±0.147 mg/kg, 1.502±0.367 mg/kg, 0.085±0.020 mg/kg, 0.120±0.024 mg/kg, 0.011±0.005 mg/kg, 0.020±0.005 mg/kg, 0.251±0.174 mg/kg and 0.025±0.021 mg/Kg for Iron (Fe), Copper (Cu), Manganese (Mn), Zinc (Zn), Lead (Pb), Cadmium (Cd), Chromium (Cr) and Arsenic (As) respectively. Among the analyzed heavy metals, highest concentration of Cu and lowest concentration of Pb was detected in all yogurt types. The values of estimated daily intake (EDI), Target hazard quotient (THQ), Total THQ (TTHQ) and Target Carcinogenic risk (TCR) confirmed that, there have no chances of any kind of carcinogenic and non-carcinogenic risks from these yogurt samples.
