Nevertheless, the ecotoxicological effects of the compounds on aquatic microorganisms have remained understudied. Hence, the present study focused on determining the effects of perfluorooctanoic acid (PFOA) and perfluorohexanoic acid (PFHxA) on the diversity, structure, microbial growth, and respiration of a freshwater microbial community. My results suggested that both compounds at high concentration changed the structure of the microbial community, but the diversity was not affected. Moreover, both compounds decreased the microbial biovolume at higher concentrations, but the net microbial respiration, in turn, was not inhibited by the compounds. This study helped to better understand the ecotoxicity of PFCAs and to assess the environmental risks associated with their use.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2021-06-29T08:21:47Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2021-06-29T08:21:47Z (GMT).
