COMPARATIVE SEED GERMINATION TESTS USING THREE PLANT SPECIES FOR TOXICITY ASSESSMENT OF TEXTILE DYEING EFFLUENT

Abstract

Effluent sample was collected from textile dyeing factory. The untreated effluent was diluted to 5%, 10%, 15%, 20%. 25%. 50%, 75% and 100%. The seed germination method was employed to assess the phytotoxicity of the effluent to maize, green gram and bhendhi. The results of the study indicated that above 50% of effluent concentration, germination was severely inhibited in the three plants, attesting to the extreme toxicity of the effluent. Among the three plant species, bhendhi was most sensitive followed by green gram. Comparatively maize was tolerant to the effluent stress.
