La pollution des ecosystemes terrestres par du cadmium d'origine industrielle (usine d'engrais phosphates) se traduit par des taches necrotiques au niveau des feuilles et par une accumulation importante de cet element dans ces feuilles et dans les horizons superficiels des sols. A proximite de la source d'emission, les taux de cadmium dans le sol depassent 10 fois les valeurs normales. Au niveau des feuilles, elles sont 10 a 30 fois plus elevees que chez les temoins et dependent de la nature de l'espece, de la distance (correlation negative) et des conditions topographiques
