Heavy metals in rice and garden vegetables and their potential health risks to inhabitants in the vicinity of an industrial zone in Jiangsu, China
Journal of Environmental Sciences-china, 2010Co-Authors: Hongbin Cao, Jianjiang Chen, Li Jun-qiao, Hui Zhang, Jun Zhang, Yi MenAbstract:Abstract Contamination of soil and agricultural products by heavy metals resulting from rapid industrial development has caused major concern. In this study, we investigated heavy metal (Cu, Zn, Pb, Cr, Hg and Cd) Concentrations in rice and garden vegetables, as well as in cultivated soils, in a rural-industrial developed region in southern Jiangsu, China, and estimated the potential health risks of metals to the inhabitants via consumption of locally produced rice and garden vegetables. A questionnaire-based survey on dietary consumption rates of foodstuffs showed that rice and vegetables accounted for 64% of total foodstuffs consumed, and over 60% of rice and vegetables were grown in the local region. Average Concentrations of Cr, Cu, Zn, Cd, Hg and Pb were 0.75, 2.64, 12.00, 0.014, 0.006 and 0.054 mg/kg dw (dry weight) in rice and were 0.67, 1.18, 4.34, 0.011, 0.002 and 0.058 mg/kg fw (fresh weight) in garden vegetables, respectively. These values were all below the Maximum Allowable Concentration in food in China except for Cr in vegetables. Leafy vegetables had higher metal Concentrations than solanaceae vegetables. Average daily intake of Cr, Cu, Zn, Cd, Hg and Pb through the consumption of rice and garden vegetables were 5.66, 16.90, 74.21, 0.10, 0.04 and 0.43 μg/(kg·day), respectively. Although Hazard Quotient values of individual metals were all lower than 1, when all six metal intakes via self-planted rice and garden vegetables were combined, the Hazard Index value was close to 1. Potential health risks from exposure to heavy metals in self-planted rice and garden vegetables need more attention.

Concentration of cadmium in rice and urinary indicators of renal dysfunction.
Occupational and environmental medicine, 1997Co-Authors: Koichi Nakashima, Etsuko Kobayashi, Koji Nogawa, Teruhiko Kido, Ryumon HondaAbstract:OBJECTIVES: (1) To examine the relation between Concentrations of cadmium (Cd) in rice and urinary Concentrations of indicators of renal dysfunction and the prevalence of abnormalities in urine in areas polluted by Cd. (2) To establish the Maximum Allowable Concentration of Cd in rice from these findings. METHODS: The target population consisted of 1703 inhabitants (832 men and 871 women) aged over 50 years who consumed home grown rice and had lived in the same hamlet in areas polluted by Cd in the Kakehashi River basin in Ishikawa Prefecture, Japan for at least 30 years. The correlation coefficients between Concentrations of Cd in rice and several urinary substances, the prevalence of abnormalities in urine and sex in hamlets polluted by Cd were calculated. Finally, regression analysis was performed for significant indicators to calculate the Maximum Allowable Concentration of Cd in rice based on values in a control group. CONCLUSIONS: Significant correlations between Concentration of Cd in rice and Concentrations of urinary beta 2-microglobulin, metallothionein, glucose, and aminonitrogen were established. Similarly, there were significant correlations between Concentration of Cd in rice and the prevalence of beta 2-microglobulinuria, metallothioneinuria, glucosuria, proteinuria, proteinuria with glucosuria, and aminonitrogenuria. The highest Maximum Allowable Concentration of Cd in rice calculated for these indicators was 0.34 ppm/l and 0.29 ppm/g creatinine. Both values are lower than 0.4 ppm, the tentative limit prescribed by the Japanese government.

health risk assessment of trace elements via dietary intake of non piscine protein source foodstuffs meat milk and egg in bangladesh
Environmental Science and Pollution Research, 2016Co-Authors: Nazma Shaheen, Md Kawser Ahmed, Md Saiful Islam, Md Habibullahalmamun, Avonti Basak Tukun, Saiful Islam, Abu Torab Ma RahimAbstract:Concentrations of six trace elements [chromium (Cr), nickel (Ni), copper (Cu), cadmium (Cd), lead (Pb) and arsenic (As)] were assessed in 'non-piscine protein source' foodstuffs (meat, milk and eggs) to evaluate contamination level and human health risks in Bangladesh. The range of Cr, Ni, Cu, Cd, Pb and As in the investigated foodstuffs was 1.24-2.17, 1.29-2.56, 0.92-2.31, 0.12-0.44, 0.15-0.48 and 0.14-0.57 mg kg fresh weight(-1), respectively. The estimated mean levels of most of the elements were higher than the Maximum Allowable Concentration (MAC) for dietary foods. The estimated daily intakes (EDIs) of Cr and Cd were higher than the Maximum tolerable daily intake (MTDI) for children, indicating that they are more susceptible to toxic elements through food consumption. The target hazard quotients (THQs) and target carcinogenic risk (TCR) of As (THQ > 1 and TCR > 10(-4)) for both the adults and children suggest that the consumers of non-piscine foodstuffs (especially cow milk and chicken meat) are exposed chronically to metal pollution with carcinogenic and non-carcinogenic health consequences.

environmental risk assessment of priority biocidal substances on polish surface water sample
Environmental Science and Pollution Research, 2021Co-Authors: Justyna Durak, Tomasz Rokoszak, Alicja Skiba, Przemyslaw Furman, Katarzyna StyszkoAbstract:The EU directive 2013/39/EU has incorporated four biocidal compounds as priority substances: diuron, isoproturon, cybutryne, and terbutryn. The research was undertaken to determine the Concentration of biocides in surface waters in three locations in southern Poland: the Wisla River in Krakow, the Wisloka River in Mielec, and the drainage ditch draining water from arable fields located near Mielec. Environmental samples were taken in two series: winter (February) and spring (May and June). The analyses were carried out using gas chromatography with mass spectrometry. The seasonality of biocides in surface waters was observed. In winter samples, the Concentrations were below MQL, while in spring, they ranged from a few to several dozen nanograms per liter. The highest Concentrations of all analyzed compounds were recorded in water taken from the Wisla River. According to directive 2013/39/EU, the Maximum Allowable Concentration was exceeded only in the case of cybutryne in water from the Wisla, both in May and in June. The assessment of the toxicity with the tested compounds was defined based on the Environmental Risk Assessment method. Low risk was estimated for diuron and isoproturon, while moderate risk for terbutryn and cybutryne.
