Formaldehyde concentrations were determined in over 1800 snow samples (snowpit, firn cores and superficial snow) from Antarctica by a sensitive spectrofluorimetric Flow Injection Analysis method. The method performances (detection limit: 55 ng/L; reproducibility: 2.5% at 1 µg/L level; linear range: 0.1–3000 µg/L) allowed a reliable determination of formaldehyde content in all the collected samples. The range of determined concentrations was 0–70 µg/L with a mean concentration of 7.7 µg/L and a median concentration of 5.8 µg/L. The formaldehyde background level was estimated at a few micrograms per liter in coastal and plateau areas of Northern Victoria Land. In some stations the background values are modulated by HCHO deposition events recurring over relatively large time periods.
