“…The high levels of Pb and Cd in the egg samples may be due to natural contamination through feeds or metal contamination in water in their habitat, with food being the primary source of Pb and Cd for humans and animals [101]. The mean levels of Cd and Hg in home-grown eggs/commercial eggs (0.016 and 0.007 mg/kg for Cd; 0.065 and 0.086 mg/kg for Hg, respectively) are more in line with those reported by some authors [10,26] and below those reported by other authors [91,[102][103][104].…”

Egg is a food product of high nutritional quality, extensively consumed worldwide. The objectives of this study were the determination of the elemental profile in eggs (egg white, yolk, and eggshell), the estimation of the non-carcinogenic health risk associated with the presence of heavy metals in investigated egg samples, and the development of statistical models to identify the best predictors for the differentiation of egg components. The assessments were carried out in a total set of 210 samples, comprising home-produced and commercial eggs, using inductively coupled plasma mass spectrometry. The results suggested measurable differences amongst hen eggs coming from different husbandry systems. The statistical models employed in this study identified several elemental markers that can be used for discriminating between market and local producer samples. The non-carcinogenic risk related to the consumption of the analyzed egg samples was generally in the safe range for the consumers, below the maximum permitted levels set by Romanian and European legislation. Food contamination is a public health problem worldwide, and the risk associated with exposure to trace metals from food products has aroused widespread concern in human health, so assessing the heavy metal content in food products is mandatory to evaluate the health risk.

“…Concentrations of Ni in 180 eggs from farms in Southern Nigeria ranged from 0.01 to 2.06 mg/kg (mean of 0.86 mg/kg) (Iwegbue et al, 2012). The Ni ranges in 24 samples of commonly consumed food crops and in 12 fruits were < 0.001 (LOD)-3.13 mg/kg and < 0.001-1.76 mg/kg, respectively (Orisakwe et al, 2012).…”

EFSA received a request from the Hellenic Food Authority (EFET) for a scientific opinion on the risk to human health from the presence of nickel (Ni) in food, particularly in vegetables. The EFSA Panel on Contaminants in the Food Chain (CONTAM Panel) decided to extend the risk assessment also to drinking water. The reproductive and developmental toxicity in experimental animals was selected as the critical effect for the assessment of chronic effects of Ni. A tolerable daily intake of 2.8 µg Ni/kg body weight (b.w.) per day was derived from a lower 95 % confidence limit for a benchmark dose at 10 % extra risk (BMDL 10 ) of 0.28 mg/kg b.w. for post-implantation fetal loss in rats. The current dietary exposure to Ni raises concern when considering the mean and 95th percentile chronic exposure levels for all different age groups. The systemic contact dermatitis (SCD) elicited in Ni-sensitive humans after oral exposure to Ni was selected as the critical effect suitable for the assessment of acute effects of Ni. A lowest BMDL 10 of 1.1 µg Ni/kg b.w. was derived for the incidence of SCD following oral exposure to Ni of human volunteers. The CONTAM Panel applied a margin of exposure (MOE) approach and considered an MOE of 10 to be indicative of a low health concern. The MOEs calculated considering the estimated mean and the 95th percentile acute exposure levels were considerably below 10 for all age groups. Overall, the CONTAM Panel concluded that, at the current levels of acute dietary exposure to Ni, there is a concern that Ni-sensitized individuals may develop eczematous flare-up skin reactions. The CONTAM Panel noted the need for mechanistic studies to assess the human relevance of the effects on reproduction and development observed in experimental animals and for additional studies on human absorption of nickel from food, for example in combination with duplicate diet studies. Following a call for data on Ni levels in food and drinking water (water intended for human consumption and mineral waters), a total of 18 885 food samples and 25 700 drinking water samples were available in the final dataset to estimate dietary exposure to nickel. No speciation data were provided. Samples were collected between 2003 and 2012 in 15 different European countries, with almost 80 % of the total collected in one Member State. The most reported analytical methods were inductively coupled plasma-mass spectrometry (ICP-MS) and atomic absorption spectrometry (AAS), that represented 54 % and 42 % of the methods reported, respectively. The highest sensitivity was reported for the analysis of drinking water with a limit of quantification (LOQ) of 0.001 µg/L (for both ICP-MS and AAS). In food, ICP-MS showed the lowest LOQ for the analysis of 'Alcoholic beverages' (0.002 µg/kg) while the lowest LOQ reported with AAS was 1 µg/kg for samples of 'Fish and seafood' and 'Sugar and confectionery'. In the final dataset, left-censored data represented 66 % of the analytical results, with 35 % in food samples and 89 % in drinking water sa...

“…Others, including As, Cd, Cr, Hg, Pb, and Sn, have no known essential function in living organisms and are toxic even at low concentrations. Heavy metals can cause serious adverse health effects in humans; thus, they are known as the most dangerous pollutants (2)(3)(4)(5)(6). Surface and groundwater resources are important for human life and for economic development (1).…”

Background: The effects of trace elements on human health and the environment gives importance to the analysis of heavy metals contamination in environmental samples and, more particularly, human food sources. Therefore, the current study aimed to predict arsenic and heavy metals (Cu, Pb, and Zn) contamination in the groundwater resources of Ghahavand Plain based on an artificial neural network (ANN) optimized by imperialist competitive algorithm (ICA). Methods: This study presents a new method for predicting heavy metal concentrations in the groundwater resources of Ghahavand plain based on ANN and ICA. The developed approaches were trained using 75% of the data to obtain the optimum coefficients and then tested using 25% of the data.
