Abstract: Impact of industrial effluents on quality of receiving waters as assessed by COD, suspended solids, and some hydrographic features has been studied over an year at 4 stations in Cochin backwaters. The effect of effluents is considerable in the vicinity of the main discharge site (st 2) in nonmonsoon months. The monsoonal floods provide adequate dilution and mask the effects. No serious oxygen depletion is noticed at any of the stations. An attempt has been made to correlate the relative abundance of benthic fauna at the stations with the water characteristics like ammonia content and organic matter.
