مصطلحات موضوعية: Heavy metals, dog, environment

الوصف: The aim of the current study was to carry out a retrospective analysis of heavy metal (Pb, Cd, and Hg) levels in liver and kidney of 38 dogs living in an urban habitat (city of Naples). Tissues were homogenized, digested in a microwave digestion system, and analyzed by atomic absorption spectrometry. The results of this study showed generally low levels of heavy metals in tissues of all examined dogs; only mercury concentrations in kidneys of pet dogs were higher than in stray dogs, and no significant age-dependent differences in metal levels were shown between the two groups. In conclusion, these results suggest the involvement of ad hoc-formulated pet food exposure to heavy metals in domestic animals.

مصطلحات موضوعية: Polychorinated biphenyls, Dioxins, Intestinal epithelial cells

الوصف: Polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins (PCDD) are persistent organic pollutants (POPs) recognized as causing adverse effects on humans, animals and environment. Exposure occurs mainly through the consumption of contaminated food, in particular those of animal origin. the aim of the current study was to evaluate the effects of three ndl-PCB congeners, PCB 138, PCB 153 and PCB 180, and tetrachlorodibenzo-p-dioxins (TCDD), alone and differently combined, on non tumorigenic rat intestinal epithelial cell line (IEC-6). The results of the current study showed that ndl-PCBs and TCDD reduced significantly cell viability only at the highest concentrations (50-100 μM and 0.1-1 μM, respectively); such effect was not linked to apoptosis induction or cell cycle arrest. The contemporary presence of more than one contaminant (differently combined) did not induce any enhancement of effects on IEC-6 cell line. Intestinal restitution was not affected by low non cytotoxic concentrations of ndl-PCBs and TCDD. The results of the current study highlight the need to continue the evaluation of toxic properties of ndl-PCBs, which represent a less studied PBCs; such studies could provide useful information in particular in term of risk assessment.

مصطلحات موضوعية: Arsenic, fish, food safety

الوصف: The relatively high concentrations of arsenic found in shellfish in recent years have contributed to raise the threshold of attention of European Union, in terms of food security. Among the various factors that influence the toxicity of arsenic, the chemical form is of particular significance, given the high toxicity of the inorganic form in respect of the organic that frequently contaminates fishery products. The Expert Committee of FAO / WHO defined a provisional tolerable weekly intake (PTWI) of 15 mg/kg b.w. only for the inorganic form and, in view of definition of residual limits for arsenic in fish, it becomes necessary to have analytical methods able to differentiate inorganic form from the organic ones (e.g. monomethyland dimethylarsenic acid, arsenobetaine, arsenocholine). The purpose of this study was to optimize and validate an analytical method for the speciation of arsenic in fishery products, that could identify and quantify the organic forms of arsenic. Screening of organic forms of arsenic was carried out using HPLC (high performance liquid chromatography) coupled to a tandem mass spectrometry detector, while determination of total arsenic was carried out using the atomic absorption spectroscopy. The validation procedure was conducted according to the requirements of the European Community to allow the use of the present method by the Official Control laboratories. The matrices considered for method optimization and validation have been fish, molluscs and crustaceans from the coasts of southern Italy. Obtained results allowed the method to enter within the routinely activities of the laboratory and require method accreditation.

مصطلحات موضوعية: Heavy metals, fishery products, food safety

الوصف: Fish products are essential and irreplaceable components of human diet; nevertheless, they could result in a risk to the health of consumers due to the potential content of some xenobiotics such as heavy metals and persistent organic contaminants (Debeka et al., 2004; Storelli et al., 2005). Constant control network and surveys are valuable tools in order to prevent such risk and to ensure product quality and consumers??? safety. The aim of the current study was to measure the levels of some heavy metals (Hg, Pb, Cd) in samples of marked canned tuna in olive oil. The results showed that levels of Cd and Hg were always within the law limits and, in many samples, below the detection limit. Pb was found in concentrations exceeding the law limits in 9.8% of the analyzed samples. In conclusion, the results of the current study, quite reassuring in terms of food safety, highlighted the need to constantly monitor the levels of some chemical contaminants in fish products such as heavy metals that might endanger the health of the consumers.

مصطلحات موضوعية: PCB, fishery products, food safety

الوصف: European Commission Regulation 882/2004/EC requires that official control laboratories for foodstuffs in the member states are certified according to UNI EN ISO/IEC 17025:2005 (general requirement for the competence of calibration and testing laboratories). This mandatory requirement has resulted in a continuous adaptation and development of analytical procedures. The aim of this study was to develop a method for semiquantitative screening of polychlorinated biphenyls in fish for human consumption. According to the Commission Decision 657/2002/CE, the detection capability, the precision, the selectivity-specificity, and applicability-ruggedness-stability were determined to validate the method. Moreover, trueness was verified. This procedure resulted in rapid execution, which allowed immediate and effective intervention by the local health authorities to protect the health of consumers. Finally, the procedure has been recognized by the Italian accrediting body, ACCREDIA.

مصطلحات موضوعية: Heavy metals, food safety, contaminants

الوصف: Fish is a good source of nutrients for humans but can pose a risk to human health because of the possible presence of some xenobiotics such as heavy metals and persistent organic contaminants. Constant monitoring is needed to minimize health risks and ensure product quality and consumer safety. The aim of the present study was to use atomic absorption spectrometry to determine the concentrations of some heavy metals (Hg, Pb, and Cd) in tuna packaged in different kinds of packages (cans or glass) in various countries (Italy and elsewhere). Concentrations of Cd and Hg were within the limits set by European Commission Regulation (EC) No 1881/2006 and in many samples were below the detection limit. Pb concentrations exceeded European limits in 9.8% of the analyzed samples. These results are reassuring in terms of food safety but highlighted the need to constantly monitor the concentrations of heavy metals in fish products that could endanger consumer health.

مصطلحات موضوعية: Heavy metals, dog, environment

الوصف: Lead, cadmium and mercury were detected in liver and kidney tissue of dogs from an urban habitat. Samples were digested in a microwave system and analyzed by atomic absorption spectroscopy. Results of the current study showed that at least one of the three heavy metals was detected in tissues of all examined dogs. These findings make us suppose that humans are exposed to the same heavy metals similar to those of dogs that are exposed since they share the same environment. Mercury concentrations detected in kidney of household dogs were higher than stray dogs, therefore the involvement of pet food in exposure to mercury can be supposed.

الوصف: The objective of this study was to estimate the levels of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and polychlorinated biphenyls (DL-PCBs and NDL-PCBs) in blood serum obtained from non-occupationally exposed volunteers living in the Naples area (Campania Region, southern Italy).The samples were taken from two geographical zones: one was an urban area of Naples and its surroundings and the other was located in an area deemed to be at high environmental risk.Total mean concentrations of these persistent pollutants proved to be in the range 1.43-17.38pgWHO-TEQ1998g-1 lipid for PCDD/Fs, and 0.98-25.45pgWHO-TEQ1998g-1 lipid for DL-PCBs. NDL-PCBs were in the range 316.57-482.90ngg-1 lipid.No significant differences were observed between women and men, nor between donors living in the two different areas.The mean levels of PCDD/Fs and PCBs in the population living in the Naples area were lower than those observed in some studies of populations living in exposed areas (near incineration plants or industrial sites) and urban or rural areas. © 2013 Elsevier Ltd.
