Abstrakt

The present study demonstrates unequivocally the presence of the natural carcinogen ptaquiloside and its transformation product pterosin B in groundwater and surface water. Groundwater concentrations up to 0.23 nmol/L (92ng/L) ptaquiloside and up to 2.2 nmol/L (0.47μg/L) pterosin B were found. Of 21 groundwater samples, 5 contained ptaquiloside, exceeding the estimated threshold for drinking water (1.3-40pmol/L). The results are critical for water abstraction in bracken-infested areas.
