Abstract :

&nbsp;Concentrations of copper (Cu) and nickel(Ni) in stem and root of Alternanthera philoxeroides Griseb. collected from three sites of Nambul river in Imphal West District of Manipur were analyzed with the help of ICP&ndash;MS during the wet (June &ndash; October) and dry (November &ndash; Feuary) seasonsof 2012 and 2013. One way ANOVA reveals significant variations among Cu concentrations in the shoot and root of the plant in the three sites. Ni concentrations in stem were also significantly differentbetween Thong Nambonbi (TN) and Wangoi (WN) (p = 0.022). In contrast, there was no significant variation among Ni concentrations in root. Both Cu and Ni absorbed by the plants growing in the river may be attributed to various anthropogenic sources including chemical fertilizers, pesticides and fungicides used in agriculture.
