This study wants to establish the effects of urban waste water irrigation on the cultivation of rice for heavy metal contamination: in particular, copper (Cu), iron (Fe) and zinc (Zn). The research studies the evolution along an irrigation line, so take nine plots along it, and the levels of these elements is checked, in root, stem and grain. It is compared with other irrigation waters from different sources, with the parallel study, which analyzed other soil and water in order to determine the interaction soil-plant-water. Finally, under the conditions of the experiment, basic soils and Mediterranean conditions do not pass the relevant quantities that could endanger the consumer.
