Trace metal contamination is a matter of global concern today and phytoremediation can clean up the contaminated environment. The objective of the study is to examine the metal accumulation efficiency of selected macroflora associated with Poovar estuary. Cyperus tenuispica Steudel, Bacopa monnieri (L.) Pennell, Mariscus javanicus (Houtt.) Merr. & Metc. and Acanthus ilicifolius L. were collected from Poovar estuary and subjected for various elemental analyses such as copper, zinc, cadmium, chromium and lead. The study revealed that all the macrophytes under study were efficient accumulators of all these metals and could be used as bioindicators for metal pollution. Study warrants the analyses of more elements in these species, which could bring the potentiality of the plants as bioindicator for metal pollution.

Keywords: Poovar estuary, macroflora, copper, zinc, cadmium, chromium and lead.
