| Abstract | A Working Group on Environmental Quality Standard (EQS) for perfluoroalkyl acids (PFAA) was formally
established by the Italian government in response to the evidence of significant sources of PFAA in Northern Italy.
The main scope was to include some of them in the list of national specific pollutants for surface (Ministerial
Decree 260/2010) and ground waters (Legislative Decree 30/2009) monitoring and classification in the context of the
Water Framework Directive (2000/60/EC). The European Directive 2006/118/EC on groundwater protection,
transposed into the national legislation through Legislative Decree no. 30/2009, requires to set threshold values for
pollutants, pollutant groups and pollution indicators, which have been identified as factors contributing to placing
groundwater bodies at risk of not reaching the "healthy state" level. The Directive indicates a minimum list of 10
parameters and requires that the member States, on the basis of existing monitoring data, set further limits for
pollutants present in the country. The organic pollutants have been chosen by considering the statistical
distribution of concentrations and frequency of detection in the Italian surface and ground waters. The chemical
compounds in the list included perfluorooctanoic acid (PFOA) and related short chain (number of carbon <7)
perfluorocarboxylic acids such as perfluorobutanoic acid (PFBA), perfluoropentanoic acid (PFPeA) and
perfluorohexanoic acid (PFHxA). Perfluorobutanesulphonic acid (PFBS), which is a common substitute of
perfluorooctanesulphonic acid (PFOS), has been included too. A dossier for each of these substances collecting
available data on regulation, physico-chemical properties, emission and sources, occurrence, acute and chronic
toxicity on aquatic species and mammals, including humans has been prepared. According to the protocol
recommended by the Technical Guidance Document on deriving EQS (CIS-WFD Guidance n. 27), Quality Standards
(QS) have been derived for the different protection objectives (pelagic and benthic communities, predators by
secondary poisoning, human health via consumption of fishery products and water). The most protective QS have
been set as the national EQS. In Italy, the limits suggested as threshold values in groundwater to be applied in the
relevant regulation (National Decree 30/2009) correspond to the ones established for the protection of human
health by drinking water consumption (PFPeA 3 ?g L-1, PFHxA 1 ?g L-1, PFBS 3 ?g L-1 and PFOA 0.5 ?g L-1). |
