Abstract(s)
Infiltration galleries are among the oldest
known means used for small public water fountains. Owing
to its ancestral origin they are usually associated with high
quality water. Thirty-one compounds, including pesticides
and estrogens from different chemical families, were analysed
in waters from infiltration galleries collected in Alto
Douro Demarcated Wine region (North of Portugal).
A total of twelve compounds were detected in the water
samples. Nine of these compounds are described as presenting
evidence or potential evidence of interfering with
the hormone system of humans and wildlife. Although
concentrations of the target analytes were relatively low,
many of them below their limit of quantification, four
compounds were above quantification limit and two of
them even above the legal limit of 0.1 lg/L: dimethoate
(30.38 ng/L), folpet (64.35 ng/L), terbuthylazine-desethyl (22.28 to 292.36 ng/L) and terbuthylazine (22.49 to
369.33 ng/L).
