title: Risk assessment of metals from consuming vegetables, fruits and rice grown on soils irrigated with waters of the Ebro River in Catalonia, Spain.
abstract: The concentrations of arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), manganese (Mn), nickel (Ni), and lead (Pb) were determined in samples of various edible vegetables (artichoke, cauliflower, lettuce, tomato), fruits (apple, mandarin, orange, pear) and rice grown in soils irrigated with water from the Ebro River in Tarragona Province (Catalonia, Spain). Although all food items were randomly acquired in various localities of the area, the local origin was always verified. Arsenic was only detected in rice (all samples) and apple (one sample), while Cd and Hg could not be detected in any of the samples. In general terms, metal concentrations were quite similar or lower than the levels recently reported in the literature. The health risks caused by metal exposure from consuming these agricultural products were assessed for the Catalan population living in the zone under evaluation. For all elements, when the lower bound values were considered, the Hazard Quotient (HQ) was <1, while using the Upper bound values, only for As (children and male seniors) HQ was >1. The intake of the analyzed elements through consumption of the nine selected food items does not mean additional health risks for the consumers of the area.
