“…In addition, most phosphate ores have to be concentrated or beneficiated before they can be used or sold on the international phosphate market.

A risk ranking model was developed to provide a systematic evaluation of the range and quantity of 28 elemental contaminants applied to land in New Zealand and applied to mineral P fertilisers. The methodology is transparent, flexible and robust and allows contamination issues to be ranked according to their real or potential impact. The quantitative ranking model is based on the relative importance of each element in relation to accumulation in soil, transfer to water or uptake by plants, toxicity to soil organisms, plants and people, and the contribution of any radioactive isotopes. The highest risk score for potential environmental significance of P fertiliser borne trace element contaminants was found for uranium, followed (in decreasing order) by cadmium, mercury, boron, fluoride, selenium, arsenic, silver and rare earth elements. The lowest score (rank 28) was attributed to strontium.

“…Knowledge of the distribution and transfer processes of uranium in the soil-water-plant system, especially in agricultural and plant production, is necessary to decrease and mitigate its effects on public health (Takeda et al 2006). Previous research work in this domain in the Cunha Baixa area was conducted by the authors (Neves et al 2003 on maize (Zea mays L.) and lettuce (Lattuca sativa L.) and by Ferreira (2007) on mushrooms (Macrolepista procera, Scop ex.…”

Large uranium accumulations in vegetable foodstuffs may present risks of human health if they are consumed. The objective of this study was to evaluate the uranium concentrations in different vegetable foodstuffs and grown in agricultural soils, which are then consumed by the residents of the village of Cunha Baixa (Portugal),--located in an former uranium mining area. This study was conducted to address concerns expressed by the local farmers as well as to provide data for uranium-related health risk assessments for the area. Soils, irrigation water and edible tissues of lettuce, potato, green bean, carrot, cabbage, apple and maize (Latuca sativa L., Solanum tuberosum L., Phaseolus vulgaris L., Daucus carota L., Brassica oleracea L., Malus domestica Borkh, Zea mays L., respectively) were sampled and uranium determined. High uranium concentrations were found in some soils (U(total) > 50 mg/kg), in irrigation waters (218 to 1,035 μg/l) and in some vegetable foodstuffs (up to 234, 110, 30, 26, 22, 16 and 1.6 μg/kg fresh weight for lettuce, potato with peel, green bean pods, cabbage, corn, carrot and apple, respectively). However, the results of the toxicity hazard analysis were reassuring the estimated level of uranium exposure through the ingestion of these vegetable foodstuffs was low, suggesting no chemical health risk (hazard quotient <1) to this uranium exposure pathway for a local residents during their lifetime, even for the most sensitive part of the population (child).

“…This analysis identified As, Cd, Cr, F, strontium (Sr), thorium (Th), U and Zn as deserving of greater investigation [40]. Data for accumulation of F in fertilized soils have been reported [30,41,42], as have data for U [32,43,44]. Nziguheba [45] also showed that, in Europe, the average annual soil application of Cd, Ni, Pb and Zn from P fertilizers was below that contributed via atmospheric deposition.…”
