Abstract:
The present study was undertaken to make a detailed investigation
for_ the assessment of specific impact of commonly used biocides at the
lower trophic level of food chain i.e., microalgae by using batch culture
techniques in the laboratory. Microalgal representatives from three habitats
i.e., fresh water, estuarine and marine were investigated. The different
biocides selected are of common use in the agricultural practices.
Because of the importance of microalgae as live feed for larval
and postlarval stages of different aquatic organisms, the fluctuations
in algal populations as a result of biocide treatment will surely affect
the food chain. These studies are also of significance in setting the
criteria and standards for water quality management by suggesting threshold
values of different biocides tested, beyond which they affect the ecosystem
adversely. The thesis has been divided into six chapters
