Abstract

Photosynthetic energy storage efficiency controls the development and decline of phytoplankton biomass. All abiotic environmental factors such as light intensity; temperature, nutrient availability and pollutants will exert detectable changes in the photosynthetic energy storage efficiency of phytoplankton, and subsequently affect total biomass and composition of phytoplankton assemblages. Since this efficiency is a sensitive amplifier of ambient conditions, it thereby is an excellent reporter of water quality parameter. We demonstrate the applicability of the novel photoacoustic method in easily and directly estimating the energy storage efficiency of phytoplankton in a drinking water reservoir of different nutrient status.
