“…The lowest concentration of Cd in paddy soils was consistent with previous studies conducted in Malaysia [1,16,19,20,21,22]. The Cd content decreased while Pb increased indicating that Pb had a higher affinity and stability to the organic matter of soil compared to the Cd element [10]. However, different findings were found by Habibah et al [23] in paddy soils from Penang and Kedah in Malaysia where Cd concentration was found high in the range of 3.54 mg/kg to 20.86 mg/kg.…”

Rice ingestion is one of the major pathways for heavy metal bioaccumulation in human. This study aimed to measure the heavy metal content of paddy soils and its bioavailability in paddy grain in order to assess the health risk. In total, 10 rice samples (50 g each) of paddy plants were harvested from the Selangor and Terengganu areas of Malaysia to assess the bioavailability of heavy metal (As, Cd, Cu, Cr, and Pb) using the in vitro digestion model of Rijksinstituut voor Volksgezondheid en Milieu. The bioavailability of heavy metal concentrations in rice samples were analyzed using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The findings showed the bioavailability of heavy metal concentrations was decreased in the order Cr > Cu > Pb > As > Cd. Chromium was found to be the most abundant bioavailable heavy metal in cooked rice, which was the result of its high content in paddy soil. Hazard Quotient values for the bioavailability of the heavy metal studied were less than one indicating no non-carcinogenic health risks for adults and children. Meanwhile, the total Lifetime Cancer Risk exceeded the acceptable value showing a potential of carcinogenic health risk for both adults and children. The application of in vitro digestion model in assessing bioavailability of heavy metal produces a more realistic estimation of human health risks exposure. However, a regular monitoring of pollution in Selangor and Terengganu areas is crucial since the exposure of heavy metals through rice consumption poses the potential non-carcinogenic and carcinogenic health risk to the local residents.

“…The bioavailable element contents of PHEs, extracted in CaCl 2 , were the following: Cd 15.4%, Cr 0.03%, Cu 0.19%, Fe 0.01%, Ni 0.96%, Pb 0.11%, and Zn 0.48% of the total PHE content. Taking under consideration low extraction efficiency of CaCl 2 , which, however, indicated significant mobility of cadmium (Ali et al 2018), further more detailed study on PHE mobility and availability of investigated arable soils seems to be justified.…”

Agricultural soil samples were collected from the areas where edible plants had been cultivated in southern Poland. The PHE content decreased in proportion to the median value specified in brackets (mg/kg d.m.) as follows: Zn (192) [ Pb (47.1) [ Cr (19.6) [ Cu (18.8) [ Ni (9.91) [ As (5.73) [ Co (4.63) [ Sb (0.85) [ Tl (0.04) [ Cd (0.03) [ Hg (0.001) [ Se (\ LOQ). No PHE concentrations exceeded the permissible levels defined in the Polish law. The PHE solubility (extracted with CaCl 2) in the total concentration ranged in the following order: Fe (3.3%) [ Cd (2.50%) [ Ni (0.75%) [ Zn (0.48%) [ Cu (0.19%) [ Pb (0.10%) [ Cr (0.03%). The soil contamination indices revealed moderate contamination with Zn, ranging from uncontaminated to moderately contaminated with Pb, and, practically, no contamination with other PHEs was identified. The ecological risk indices revealed that soils ranged from uncontaminated to slightly contaminated with Zn, Pb, As, Cu, and Ni. The PCA indicated natural sources of origin of Co, Cu, Hg, Sb, Zn, Cr, and Pb, as well as anthropogenic sources of origin of Cd, Ni, As, and Tl. The human health risk assessment (HHRA) for adults and children decreased in the following order of exposure pathways: ingestion [ dermal contact [ inhalation of soil particles. The total carcinogenic risk values for both adults and children were at the acceptable level under residential (1.62E-05 and 6.39E-05) and recreational scenario (5.41E-06 and 2.46E-05), respectively, as well as for adults in agricultural scenario (1.45E-05). The total noncarcinogenic risk values for both adults and children under residential scenario (1.63E-01 and 4.55E-01, respectively), under recreational scenario (2.88E-01 and 6.69E-01, respectively) and for adults Electronic supplementary material The online version of this article (

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.
