Survey of Antifungal in Surface- and Groundwater: A Portuguese Environmental Case Study
Antifungals support modern medical and agricultural practices, and extensive screening environmental data are missing. This work aims to survey antifungals for medical and agricultural purposes in surface- and groundwater in Portugal. A passive sampling technique and a high-resolution chromatographic system were used. Antifungals applied in medical practice were not detected as only antifungals for agricultural purposes (fungicides). Thirty-nine different fungicide molecules were found; its detection frequency in surface- and groundwater was dominated by rabenzazole (61%, 92%) and ethoxyquin (54%, 77%); among the five fungicides with similar surface- and groundwater catching rates, ferimzone was the most polluting (54%, 54%); oxadixyl (61%), kresoxim-methyl (61%) and fenamidone (46%) were primarily designated surface water contaminants; for azoles, the occurrence in surface water ranged from a residual (10%) to a moderate detection rate for two compounds (31%—propiconazole and tebuconazole). Surprisingly, only 51% of detected fungicides are authorised. The frequently detected fungicides that are either not authorised (ethoxyquin and its impurity, furmecyclox, oxadixyl), without data in the EU (rabenzazole, ferimzone), or authorised at the national level (fenamidone), should be included in environmental monitoring programmes and followed as emerging (micro)contaminants. Policy makers should gather their efforts to allow the implementation of proper risk management and effective contamination control strategies to achieve Sustainable Development Goals.
