Abstract:The influence of sulphite mill effluents on the heterotrophic activity of natural populations in the recipient water was studied during the summer of 1979 . A single concentration method (3-H-glucose, 0 .05 µg 1-1 ) was used to measure the heterotrophic activity . The influence of the effluent was studied by adding it in concentrations varying from 0 .001 to 10% to water samples derived from different sections of the watercourse . Adaptation to rather high concentrations of the effluent was observed near to th… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
