An extensive data set of total arsenic analysis for 901 polished (white) grain samples, originating from 10 countries 4 continents, was compiled. The samples represented the baseline (i.e., notspecifically collected contaminated areas), and all were market sale in major conurbations. Median contents rice varied 7-fold, with Egypt (0.04 mg/kg) India (0.07 having lowest content while U.S. (0.25 France (0.28 had highest content. Global distribution modeled by weighting each country's that...
Paired grain, shoot, and soil of 173 individual sample sets commercially farmed temperate rice, wheat, barley were surveyed to investigate variation in the assimilation translocation arsenic (As). Rice samples obtained from Carmargue (France), Doñana (Spain), Cadiz California, Arkansas. Wheat collected Cornwall Devon (England) east coast Scotland. Transfer As grain was an order magnitude greater rice than for wheat barley, despite lower rates shoot-to-grain transfer. levels over 0.60 μg g-1...
Cereal grains are the dominant source of cadmium in human diet, with rice being to fore. Here we explore effect geographic, genetic, and processing (milling) factors on grain consumption rates that lead dietary variance intake. From a survey 12 countries four continents, levels were highest Bangladesh Sri Lanka, both these also having high per capita intakes. For there was weekly intake from rice, leading intakes deemed unsafe by international national regulators. While genetic variance,...
Trace element contamination is one of the main problems linked to quality compost, especially when it produced from urban wastes, which can lead high levels some potentially toxic elements such as Cu, Pb or Zn. In this work, distribution and bioavailability five (Cu, Zn, Pb, Cr Ni) were studied in Spanish composts obtained different feedstocks (municipal solid waste, garden trimmings, sewage sludge mixed manure). The showed total concentrations these elements, cases limited their...
Interest in using urban waste composts as amendments agriculture is growing nowadays. However, concerns about the potential transference of pollutants present to food chain are very relevant when they recycled for or animal feed production. Thus, safe use composts, it has be assured that no risk metal plants from compost exists. In this work, heavy metals been studied an experiment with lettuce and Italian ryegrass, grown substrates based on five metal-rich a manure vermicompost (included...
