Título: Chromium in soil and plants: bioavailability and mechanisms of absorption.

The goal of this lecture is to present chromium role in a plant-soil system and connection with its bioavailability. The relationship between chromium concentrations in the soil and plants is extremely important, not only from the aspect of its influence on plant growth and capacity of plant accumulation but also for potential toxicity for humans.

The main objectives of this lecture are to discuss the bioavailability of two chromium species (Cr3+ and chromate ion) in contaminated soil, the capacity of the root system for chromium binding and its role in the protection from its toxic action.  Also, the role of iron and manganese oxides and hydroxides, as the most common chromium substrates, will be explained, as well as the influence of soil acidity to chromium mobilization and accumulation.

This lecture could contribute to the better explanation of the chemical environment that modifies many equilibria in which chromium appears, influencing its qualitative and quantitative presence in both, soil and plants.
