Four biochemical parameters; pH, ascorbic acid content, relative water content and total chlorophyll content on leaves were tested at Beddagana wet land park and Panchikawatta, Pettah and Maradana area in Colombo Municipal Council which varying air pollution levels with regards to SO 2 , NO 2 and PM 2.5 levels in ambient air.
