Abstract

Abstract: Per-and polyfluoroalkyl substances (PFAS) is a collective name for approximately 4700 synthetic chemicals ubiquitous in the aquatic environment worldwide. They are used in a wide array of products and are found in living organisms around the world. Some PFAS have been associated with cancer, developmental toxicity, endocrine disruption, and other health effects. Only a fraction of PFAS are currently monitored and regulated and the presence and effects on aquatic organisms of many PFAS are largely unknown. The aim of this study is to investigate the health effects of environmentally relevant concentrations of PFAS on aquatic organisms at different consumer trophic levels through a systematic review and meta-analysis. The main result shows that PFAS in concentrations up to 13.5 μg/L have adverse effects on body size variables for secondary consumers. However, no significant effects on liver or gonad somatic indices and neither on fecundity were found. In addition, the results show that there are large research gaps for PFAS effects on different organisms in aquatic environments at environmentally relevant concentrations. Most studies have been performed on secondary consumers and there is a substantial lack of studies on other consumers in aquatic ecosystems. Graphical abstract: Image 1 Highlights: Meta-analytic review on the effects of PFAS on aquatic organisms at different trophic levels. PFAS affect the length and weight of aquatic organisms at consumer trophic levels. Very few of the PFAS are studied in environmental concentrations. Few studies on the effects of PFAS on aquatic primary and tertiary consumers. Behavior studies are lacking in publications of PFAS effects in aquatic organisms.
