Abstract

The study was carried out in Ayroor river (Kerala) to assess the water quality for a period of six months from December, 2006 to May, 2007. Physico-chemical parameters of water and zooplankton diversity were estimated. High values of BOD (10.2-15.6 mg/l), COD (160-230 mg/l), TDS (200-1400 mg/l), free CO2 (22-88 mg/l), nitrate (1.65-13.99 mg/l) and MPN coliform (5000/100 ml) coupled with low dissolved oxygen content (2-4.2 mg/l), low diversity index (1.170-1.563) and presence of indicator species confirm high organic pollution in the river.
