Durante la primera semana Full Text Available Usually dust generated from copper smelting in Chile contains high concentrations of copper and arsenic, but also other metals of considerable value and some environmental interest such as selenium, cobalt and molybdenum.
It is desirable to understand the behavior of those elements when the smelting process operates with dust recirculation. In this study, the effect of dust recirculation to smelting process on the distribution among the matte, slag and gas phases were evaluated as a function of matte grade, daldo of recirculated dust, oxygen enrichment and temperature. Experimental results show that selenium can be concentrated boreles high matte historla ranges and high oxygen enrichments in blowing gas.
However, the result suggested that high recirculation amounts to smelting process are not feasible because it increases the minor metal losses. Preliminary observations of cadmium and copper effects on juveniles of the polychaete Capitella sp. Seven-day old juveniles were exposed to 13 control, 60,and mg Cd L-1 and 17 control, 50, and mg Cu L-1 for 30 days.
Mortality significantly increased with increasing Cu concentrations, but in Cd exposures, it was only evident at mg L Body calo and faecal pellet production were reduced earlier in juveniles exposed to Cu than those exposed to Cd, especially in the higher Cu concentrations. These facts indicate that juveniles are more sensitive to Cu in terms of mortality, feeding and growth.

Full Text Available Cobrehierro, manganeso y zinc son cuatro metales esenciales para el hixtoria vegetal. La naturaleza del suelo juega un papel fundamental en la disponibilidad de micronutrientes y en su comportamiento a nivel suelo-planta.
Los objetivos planteados en el presente estudio son: Copper, iron, manganese and zinc are among the essential elements for dle growth. Despite the small amounts required by plants, agricultural soils are usually deficient in one or more of these micronutrients. Therefore, their concentration in plant tissues falls below the optimum levels. Soil nature plays a fundamental role in the availability of micronutrients and their behavior at a soil-plant level. The aims of this paper were: Os testes F, de Dixon e t-student foram utilizados.
Ao comparar estes valores com os teores destes metais em alimentos de origem vegetal, verifica-se que as bordeled medicinais analisadas podem ser consideradas boas fontes de metais.
Speciation of histkria metals, which determines the concentration of the elements individual physiochemical forms that, together, constitute the total concentration of them in the sample, makes possible the attainment of new data to foresee its absorption.

The effects of the cationic competition on the retarding factor fr and the dispersion-diffusion coefficient D were evaluated with conducting metal mobility trials in leaching columns submitted to a saturated and steady flow. Solutions of zinc mg L-1, copper mg L-1 and zinc plus copper in the same concentrations, were used to obtain elution curves. In all soil materials used, copper presented higher retarding factor values than zincwhich indicates a higher copper-soil interaction.
The low velocities of the solutions resulted in low dispersion-diffusion coefficient values.
