Abstract

Macrophytes are important components of Lake Ecosystem. The present study was done to assess diversity, biomass, nutrient and metal accumulation ability of macrophytes from Jakkur Lake, Bengaluru. Macrophytes were sampled from inlet and outlet of the Lake. After identifying species, they were washed thoroughly to remove adhering sediments and periphytons. They were dried to constant weight using hot air oven and the dry weight was determined. The dried samples were powdered to get fine powders and were analysed for nutrient and heavy metals using standard procedures. Total nine species of macrophytes (four floating and five emergent) belonging to eight families were found in the study site. Polygonum and Typha angustata had higher biomass in inlet and outlet respectively. In inlet Polygonum, Alternanthera philoxeroides and Typha angustata had higher concentration of Carbon, Nitrogen and Phosphorus respectively. Carbon content was higher in Typha angustata, Nitrogen and Phosphorus was highest in Spirodela polyrhiza in the outlet of the Lake. Cadmium concentration was within normal range (0-1.8 mg/kg) with Alternanthera philoxeroides and Pistia stratiotes accumulating highest in inlet and outlet. Typha angustata in inlet had Copper concentration in critical range whereas in outlet all species had normal range with Ludwigia sp the highest. Lead, Zinc, Nickel and Chromium was in higher concentration in Typha angustata than other species in inlet. Nickel was above normal range in Typha angustata in inlet and in all species in outlet. In the outlet Typha angustata (Lead), Pistia stratiotes (Zinc and Nickel) and Alternanthera philoxeroides (Chromium) had higher concentrations. Thus the study highlighted the remediation potential of Macrophytes from Jakkur Lake.
