Influence of metal process micronic and submicronic particles on vegetables quality and ecosystems

Abstract : Impact of atmospheric process particles enriched with metals (PM) on various vegetables was studied. Foliar metal interception was measured and calculated. Soil-plant transfer and phyto-toxicity were also studied. Influence of species and washing procedure on metal burning was observed. High correlation was obtained between measured and simulated lead plant uptake values. Ageing effect in polluted soils was highlighted with stabilisation or mobilization of metals in function of contact duration between soils and PM.
