Abstract

This study determined the extent of heavy metal contamination of local fruit in Rayong, Thailand, an area where an industrial base is adjacent to agricultural areas. Dietary exposure to agricultural products grown in contaminated areas can cause multiple adverse effects to the human body. In order to avoid such undesirable effects, concentrations of heavy metals [arsenic (As), cadmium (Cd), copper (Cu), mercury (Hg), lead (Pb), and zinc (Zn)] were investigated in popular tropical fruits from three districts of Rayong, namely Wang Chan, Klang and Mueang. The levels of heavy metals were determined by inductively coupled plasma-mass spectrometry (ICP-MS) and cold vapor-atomic absorption spectrometry (CV-AAS). Levels of the six heavy metals in sampled fruits (durian, jackfruit, pineapple, rambutan, long kong, and mangosteen) were in the range of 0.0004-6.7095 mg/kg; 16.7% of fruit samples exceeded maximum permissible limits of Pb. Based on health risk assessments, values of estimated daily intake (EDI) were less than those of maximum tolerable daily intake. However, for non-carcinogenic risks, high hazard index (HI) values were found in some markets while for carcinogenic risks (CRs), CR values of three fruits (durian, jackfruit, and mangosteen) exceeded acceptable levels. Therefore, long-term fruit consumption could impact health of local consumers. These results provided insight into the need for regular monitoring of heavy metal concentrations in potentially contaminated fruits and for prevention of its potential effects.
泰国罗勇省工业园区附近热带水果中重金属残留的测定:风险评估研究
这项研究确定了泰国罗勇当地水果的重金属污染程度,该地区的工业基地毗邻农业区。在饮食中接触污染地区种植的农产品会对人体造成多种不利影响。为了避免这种不良影响,研究了罗勇三个地区(即王产、巴生和木昂)流行热带水果中重金属[砷(As)、镉(Cd)、铜(Cu)、汞(Hg)、铅(Pb)和锌(Zn)]的浓度。通过电感耦合等离子体质谱法(ICP-MS)和冷蒸气原子吸收光谱法(CV-AAS)测定重金属含量。采样水果(榴莲、菠萝蜜、菠萝蜜,红毛丹、龙孔和山竹)中的六种重金属含量在0.0004-6.7095毫克/公斤之间;16.7%的水果样品超过了铅的最大允许限量。根据健康风险评估,估计每日摄入量(EDI)的值小于最大可容忍每日摄入量的值。然而,对于非致癌风险,在一些市场中发现了高危险指数(HI)值,而对于致癌风险(CR),三种水果(榴莲、菠萝蜜和山竹)的CR值超过了可接受的水平。因此,长期食用水果可能会影响当地消费者的健康。这些结果为定期监测可能受到污染的水果中的重金属浓度和预防其潜在影响的必要性提供了见解。

期刊介绍: The Environment and Natural Resources Journal is a peer-reviewed journal, which provides insight scientific knowledge into the diverse dimensions of integrated environmental and natural resource management. The journal aims to provide a platform for exchange and distribution of the knowledge and cutting-edge research in the fields of environmental science and natural resource management to academicians, scientists and researchers. The journal accepts a varied array of manuscripts on all aspects of environmental science and natural resource management. The journal scope covers the integration of multidisciplinary sciences for prevention, control, treatment, environmental clean-up and restoration. The study of the existing or emerging problems of environment and natural resources in the region of Southeast Asia and the creation of novel knowledge and/or recommendations of mitigation measures for sustainable development policies are emphasized. The subject areas are diverse, but specific topics of interest include: -Biodiversity -Climate change -Detection and monitoring of polluted sources e.g., industry, mining -Disaster e.g., forest fire, flooding, earthquake, tsunami, or tidal wave -Ecological/Environmental modelling -Emerging contaminants/hazardous wastes investigation and remediation -Environmental dynamics e.g., coastal erosion, sea level rise -Environmental assessment tools, policy and management e.g., GIS, remote sensing, Environmental -Management System (EMS) -Environmental pollution and other novel solutions to pollution -Remediation technology of contaminated environments -Transboundary pollution -Waste and wastewater treatments and disposal technology
