Sertraline Hydrochloride Exposure Leads to Reactive Oxygen Species Burst in Model Microalgae Species (Raphidocelis subcapitata)

Microalgae play important ecological roles and serve as useful models for assessing impacts of environmental contaminants on lower trophic aquatic organisms. Sertraline, a commonly prescribed selective serotonin reuptake inhibitor (SSRI) found in urban waters, has been observed to induce chlorosis in Raphidocelis subcapitata close to environmentally relevant concentrations. This study estimated potentially hazardous concentrations of sertraline hydrochloride by deriving transcriptomic and metabolomic points of departure (tPODs and mPODs) below which chronic adverse effects would not be expected. Additionally, an Adverse Outcome Pathway describing the mechanism by which sertraline hydrochloride impacted R. subcapitata was proposed using a multi-omics approach. This data contains the raw and processed files of nontargeted metabolomics for extracted R. subcapitata metabolites after exposure to sertraline hydrochloride.
