“…For example, soil S had the highest concentrations of Cu, Pb and Zn but plants grown in soil S consistently had the lowest BCF values for these three metals. This is in agreement with Alam et al (2003) who found that BCF values for As decreased as metal soil content increased. Sharma and Dubey (2006) reported similar results indicating that concentrations of Cd decreased in all plant parts as application rates of a multi-metal mixture increased.…”

Purpose This study explores the effect of varying organic matter content on the potential human health risk of consuming vegetables grown in urban garden soils. Results and discussion Overall, the consumption of lettuce and green bean pods grown in some urban gardens posed a potential human health risk due to unacceptably high concentrations of cadmium or lead. In many cases, compost amendment increased the accumulation of metals in the vegetables. Even in soils considered uncontaminated by current guidelines, some hazard quotients exceeded the threshold value of 1. The compost used in this study had a high fulvic acid to humic acid ratio, which may explain increased concentrations of metals in plants grown in compost-amended soils. Materials and methodsConclusions These results indicate a need to include soil characteristics, specifically organic matter quality, when setting threshold criteria for metal content of urban garden soils.

“…Moreover, the fact that the Ni content was always higher in forest areas than in cultivated soil reinforces the natural origin of the element. Decreased Ni levels may occur in cultivated areas due to Ni removal by crops, uptake via agricultural inputs or leaching into deeper soil layers (Mendes et al 2006, Antoniadis & Tsadilas 2007. In addition, Ni exhibits greater affinity to soil organic matter (Senesi et al 1989), which is found in higher concentrations in soils under natural vegetation (Table 2), and may reduce Ni losses in the system.…”

“…As such, monitoring the soil quality in these areas is vital for risk assessment. For example, Peris et al (2007) recorded Cu, Pb and Zn enrichment in soil used to grow vegetables in Spain, while Alam et al (2003) reported the contamination of vegetable species with As, Cd and Pb, in a soil in Bangladesh.…”

Heavy metals are naturally found in soils, but their levels may increase as a result of anthropogenic actions. This study aimed at determining the concentrations of Cd, Cu, Mn, Ni, Pb and Zn in Yellow Latosol from vegetable crops areas, as well as the influence of the cultivation and position in the landscape on the accumulation of these elements. Soil samples were collected from five farming areas and four areas with natural vegetation, which served as a reference. Soil was collected along the planting rows from three transect positions (upper, middle and lower sections of the slope), as well as from the upper portion of forest areas, at three depths (0.0-0.10 m, 0.10-0.30 m and 0.30-0.60 m). The results from the chemical analyses indicated that Cd, Cu, Mn, Pb and Zn levels in the soil increased as a result of cultivation. Only Cd and Cu concentrations were above the quality reference values for the Pernambuco State. The multivariate analysis techniques used were efficient at separating the environments and at differentiating the origin of the metals. Soils from forest areas were clearly separated from croplands, demonstrating the effect of agricultural practices on the metal contents in the soils. The principal component analysis indicated a predominantly anthropogenic origin (phosphate fertilizing) for Cd, in more superficial soil samples.

“…A number of surveys have reported the contamination of As in rice (Schoof et al, 1998;Heitkemper et al, 2001;Alam et al, 2003;Kohlmeyer et al, 2003;Meharg and Rahman 2003;D'Amato et al, 2004;Meharg 2004;Williams et al, 2005). Recent studies have also shown that baby rice (precooked and milled rice) and rice milk (enzyme extracted rice product used as a dairy and soya milk alternative) have elevated inorganic arsenic contents (Meharg et al, 2008a,b).…”

Rice has been demonstrated to be one of the major contributors to arsenic (As) in human diets in addition to drinking water, but little is known about rice products as an additional source of As exposure. Rice products were analyzed for total As and a subset of samples were measured for arsenic speciation using high performance liquid chromatography interfaced with inductively coupled plasma-mass spectrometry (HPLC-ICP-MS). A wide range of rice products had total and inorganic arsenic levels that typified those found in rice grain including, crisped rice, puffed rice, rice crackers, rice noodles and a range of Japanese rice condiments as well as rice products targeted at the macrobiotic, vegan, lactose intolerant and gluten intolerance food market. Most As in rice products are inorganic As (75.2-90.1%). This study provides a wider appreciation of how inorganic arsenic derived from rice products enters the human diet.
