Este estudo centra-se na avaliação da poluição por metais pesados, em particular a análise dos iões de cobre Cu2+ e iões de zinco Zn2+ fixados nos leitos de agriões da Andravoahangy. Os iões Cu2+ e Zn2+ são elementos metálicos vestigiais que podem ser encontrados no solo sob várias formas (catiónicos, complexados...). Podem ser distribuídos entre 2 compartimentos: a fase sólida e a fase líquida. A distribuição destes dois metais torna possível medir os seus níveis de enriquecimento e determinar se o solo tem um controlo adequado sobre as suas mobilidades. As experiências são levadas a cabo no laboratório de química ambiental. Utilizámos experiências BATCH. O estudo da mobilidade dos iões Cu2+ e Zn2+ é feito em amostras de solo da mesma quantidade; a cada uma delas são adicionadas soluções de sulfato de cobre e acetato de zinco de diferentes concentrações. A análise dos parâmetros associados ao estudo pedológico do solo permite interpretar o modo de adsorção de Cu2+ + Zn Cu + Zn2+ iões.
