| Abstract | Determination of 20 PFASs in a fish species (Alosa agone) of commercial interest has been carried out in five
Italian subalpine lakes to assess the risk for humans and predators for fish consumption. PFOS still presents
the highest concentrations (0.9-16.6 ng g-1 ww) among the analysed PFASs, in spite of its normative
restrictions. PFOS concentrations measured in all lakes, except in Lake Maggiore, are homogeneous with
an average of 3.1 ± 1.9 ng g-1 ww, which could be considered the "anthropogenic background concentration"
of PFOS in fish of lakes located in an industrialised and urbanised region but without point sources. In Lake
Maggiore, fish concentrations always exceed the EU EQSbiota (9.1 ng g-1 ww) based on human fish
consumption. Considering the effective consumption of fish in this area, an actual risk for fish consumption by
humans is not evidenced, while a moderate risk of secondary poisoning for predators is highlighted. PFOA has
been detected in significant concentration only in one sample in Lake Maggiore, while long chain PFCAs have
been detected without significant differences among the lakes (0.3 to 2.7 ng g-1 ww). The present study
demonstrates that biota monitoring of fish can be used as a valuable tool to classify the quality status of
water bodies regarding bioaccumulative PFAAs, even if the water concentrations are close to the reachable
detection limits. |
