"This book describs a study carried on the ecology of Benthic river algae with special reference to Bacillariophyceae and relations of physico-chemical and biological variables to pollution. The work was conducted on the river Gomati within the municipal limits of Lucknow, Uttar Pradesh, India." (jacket)
