  abstract = {{B}acteria and phytoplankton are key players in aquatic ecosystem functioning. {T}heir interactions mediate carbon transfer through the trophic web. {C}hemical contamination can alter the function and diversity of phytoplankton and bacterioplankton, with important consequences for ecosystem functioning. {T}he aim of the present study was to assess the impact of chemical contamination on the interactions between both biological compartments. {T}wo contrasting marine coastal ecosystems, offshore waters and lagoon waters, were exposed to chemical contamination (artificial or produced from resuspension of contaminated sediment) in microcosms in four seasons characterized by distinct phytoplankton communities. {O}ffshore waters were characterized by a complex phytoplankton-bacterioplankton network with a predominance of positive interactions between both compartments, especially with {H}aptophyta, {C}ryptophyta, and dinoflagellates. {I}n contrast, for lagoon waters, the phytoplankton-bacterioplankton network was simpler with a prevalence of negative interactions with {O}chrophyta, {C}ryptophyta, and flagellates. {C}ontamination with an artificial mix of pesticides and trace metal elements resulted in a decrease in the number of interactions between phytoplankton and bacterioplankton, especially for offshore waters. {R}esuspension of contaminated sediment also altered the interactions between both compartments. {T}he release of nutrients stored in the sediment allowed the growth of nutrient limited phytoplankton species with marked consequences for the interactions with bacterioplankton, with a predominance of positive interactions, whereas in lagoon waters, negative interactions were mostly observed. {O}verall, this study showed that chemical contamination and sediment resuspension resulted in significant effects on phytoplankton-bacterioplankton interactions that can alter the functioning of anthropogenic coastal ecosystems.},
