“…Industrial urban areas in many parts of the world have increased the presence of heavy metals into the terrestrial environment which have potential health impacts of consuming contaminated products such as vegetables (Cao et al 2010). Perishable vegetables are often grown around urban areas, which are more prone to heavy metal contamination due to variety of urban and industrial activities.…”

Abstract:In this study, heavy metals pollutions in waters, soils and vegetables were investigated from farms, near oil refi nery in south of Tehran city, Iran (Shahre Ray). The most important heavy metals in Iranian oil are vanadium, cobalt, nickel, arsenic and mercury (V, Co, Ni, As, Hg). In this region, the concentration of heavy metals in soils, well waters and leafy edible vegetables were evaluated in ten different points of farms. Geographic information systems (GIS) were used to estimate the levels of heavy metals concentration at unmeasured locations. After sample preparation, concentrations of heavy metals in vegetables, soils and waters were determined by atomic absorption spectrometry (AAS). Five different leafy edible vegetables from farms, i.e., Persian leek, dill, parsley, spinach and radish were sampled in spring, summer and autumn 2012. In vegetables and well water samples, the concentrations of V, Ni and Co were above the permissible limit of heavy metals as compared to WHO guidelines and the concentrations of these metals in agricultural soils were found to be lower in accordance to soil references. The industrial waste waters had high concentration of heavy metals in this area. In consequence, the results of this study indicate that industrial waste water can cause pollution in well waters and edible vegetables. So, this region is not suitable for cultivation and growing vegetables.Unauthenticated Download Date | 5/13/18 2:45 AM

“…Geologically, Ron Phibun is part of the Southeast Asian Tin Belt [1]. Many research have been carried out on the assessment of potential health risks for inhabitants in the vicinity of hazardous sites through their exposure to environmental heavy metals via consumption of farm crops [2]- [10]. Skin cancer was first reported in 1987 among other observed symptoms.…”

Abstract-Arsenic is a chemical element present in the environmental from both natural and human source. The accumulation of the excessive amounts of arsenic in rice can cause health problems in consumer as rice is a staple food mainly consumed in Thailand. The purpose of this study was to investigate the concentrations of arsenic in local rice grains and to assess the exposure to arsenic through local rice consumption. Rice samples were randomly collected from three sub districts of Ron Phibun district based on the rice cultivation areas. The concentrations of arsenic contaminated in rice sample cultivated in Ron Phibun district, southern Thailand, the abandoned tin mining site, were investigated using inductively coupled plasma optical emission spectrometry (ICP-OES) coupled with microwave-assisted technique under high pressure and temperature conditions. The estimated daily intake, common index for metal transfer from plant to human, was used to assess the health risk from arsenic through local rice consumption. It is found that the arsenic concentrations were in the range of 0.291-1.361 mg/kg which were lower than Thai FDA recommendation. The estimated daily intake (EDI) of arsenic by the local people ranged from 1.522 to 7.120 g/day kg body weight. Although the estimated daily intake values of arsenic through rice consumption were lower than the standard, the potential health risk from exposure to arsenic need more attention.

“…Cheng et al (2005) reported that the amount of Cd-contaminated rice on sale exceeding the national allowable limit of 0.2 mg/kg was 10.3% of the total in 2002 (Ministry of Health of China and the Standardization Administration of China, 2005). Specific investigations were also carried out in other provinces such as Hunan (Williams et al, 2009;Lei et al, 2015), Guizhou , Guangdong (Zhuang et al, 2009;Bian et al, 2013), Zhejiang (Huang et al, 2013), and Jiangsu (Zhao, Zhou et al, 2002;Zhen et al, 2008;Hang et al, 2009;Cao et al, 2010). An estimate of the direct economic losses from the effect of Cd contamination of crops is more than 20 billion RMB (3.20 billion in US$) .…”

Agricultural soils can be contaminated by industrial activities such as mining and smelting. Contamination with cadmium (Cd) can significantly exceed average background values, which can lead to uptake by rice plant and even harm to humans through food chain. In Hunan province, southern China, rice (Oryza sativa L.) is the main cereal, and human exposure to metallic contaminants through rice pathway is of particular interest. Shortage of land for rice growing means that contaminated agricultural soil is still cultivated for rice in Hunan. In the present work, a field experiment was undertaken to remediate Cd-contaminated paddy soil with three mineral amendments, namely sepiolite, bone char, and a silicon-based product (normally used as fertilizer). Average Cd concentration in the paddy soil was 2.85 mg/kg, significantly exceeding Chinese soil quality standards of China. Cd content was 0.59 mg/kg in sepiolite, 0.28 mg/kg in bone char, and 0.44 mg/kg in silicon fertilizer, respectively. Distribution fractions of Cd in soil followed the order of exchangeable (FI) > organic matter-bound (FIII) > residual (FIV) > oxide-bound (FII) without treatment, while exchangeable (FI) > residual (FIV) > organic matter-bound (FIII) > oxide-bound (FII) after treatment. With addition of three amendments, soil pH values and rice growth such as plant height and ripening rate increased. Concentrations of Cd in the rice plant (straw, husk, and unpolished rice) decreased after treatment. However, among three amendments, only the bone char addition reduced Cd accumulation in the rice plant below the Chinese standard value (0.2 mg/kg) and in the husk to below the Chinese feed hygiene standard for food (0.5 mg/kg).
