| Abstract | The evidence that in Northern Italy
significant sources of perfluoroalkylacids (PFAA)are present induced
the Italian government to establish a Working Group on Environmental
Quality Standard (EQS) for PFAA in order to include some of them in
the list of national specific pollutants (Ministerial Decree 260/2010) for
surface water monitoring and classification in the context of the Water
Framework Directive (2000/60/EC) The substances have been chosen
by considering the statistical distribution of concentrations and
frequency of detection in the Italian surface and ground waters. The
substances 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. For each
of these substances a dossier has been prepared which collects available
data on regulation, physico-chemical properties, emission and sources,
occurrence, acute and chronic toxicity on aquatic species and mammals,
including humans. 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) according to the protocol recommended by
the Technical Guidance Document on deriving EQS (CIS-WFD
Guidance n. 27). The most protective QS has been chosen as the
national EQS. For all compounds it is not possible to derive a QS for
sediments because in some cases compounds do not accumulate in
sediment and in other cases data on toxicity on benthic community are
lacking. For PFBA, PFPeA, PFHxA and PFBS it is not possible also to
back-calculate a QS for water from QS for biota because they have low
bioaccumulation properties or data on bioconcentration factors (BCF)
are lacking. For these compounds limits derived for the protection of
human health by drinking water consumption are adopted as EQS. In the
case of PFOA it is possible to derive a QS for biota both for the
protection of predators and human via fish consumption and backcalculate
QS for water. The calculation resulted in a QS for secondary
poisoning of 0.1 ?g L-1 which has been proposed as EQS for PFOA in
internal surface waters.
