Health hazard in the Baltic sea: the effect of fluorinated substances on Baltic sea organisms
Abstract [en]
Per- and polyfluoroalkyl substances (PFAS) is a collective name for approx. 5000 synthetic chemicals used in a myriad of products, such as nonstick frying pans, waterproof clothing, cosmetics and firefighting foam. They are sometimes called “forever chemicals” as they break down very slowly, if at all, in the environment. They are found in indoor and outdoor environments, wildlife and in virtually every human and have been associated with cancer, developmental toxicity, and other negative health effects. Plausible point sources of PFAS are the many sewage treatment plants draining into in the Baltic Sea. Very little is known about the amounts and composition of PFAS coming from STPs as well as the effects from them on the Baltic Sea organisms. We believe that the PFAS currently monitored (commonly around 20 of the 5000 substances) only comprise a small fraction of the total PFASs released. The disparity between the PFAS monitored and the PFAS used, suggests that the exposure to PFASs in the environment is largely underestimated. The aim of this project is to measure the concentrations and composition of PFAS, in water, sediment and organisms in Baltic Sea food webs in the vicinity of STPs by combining methods of determining the different fractions of fluorine; known and unknown PFASs (i.e. fluorine mass balance, FMB). In addition, effects of developmental exposure from emerging and unstudied PFAS will be evaluated in experiments in two Baltic Sea organisms.

Abstract [en]

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.
