  • Veröffentlicht auf dem Publikationsserver der RWTH Aachen University
  • Kurzfassung Die vorliegende Dissertation fokussiert sich auf zwei Aspekte der Interaktion zwischen Phytoplankton und chemischen Verunreinigungen in aquatischen Systemen
  • In comparison to Microcystis, the green algae were more sensitive to the herbicides as the cells resorted to amino acid catalysis pathways to obtain energy when the photosynthesis is constrained
  • The accumulation of glycolate and glycoxylate in the photorespiration pathway were increased in the Microcystis but decreased in the green algae in response to high exposures of the herbicides
  • Results from cell-based bioassays suggested the occurrence of estrogenic, anti-estrogenic, anti-androgenic, and anti-glucocorticogenic activities, while no androgenic and glucocorticogenic activities were observed in the samples
  • In order to further evaluate the role of cyanobacterial blooms in the distribution of endocrine disruptive compounds in eutrophic freshwaters, endocrine disruptive potentials in phytoplankton samples were evaluated throughout a year-long surveillance
  • The present study provides complementary information about the potential endocrine disruptive risks of cyanobacteria blooms in eutrophic freshwaters
