Tetrachloroethene in spruce needles is quantitatively determined by extraction with hexane, separation by capillary gas chromatography, and detection by chemical-ionization mass spectrometry, monitoring the negatively charged chlorine ions. Needle samples from spruces growing in forests and in a city in Southwest Germany and from spruces in exposure chambers have been analyzed; concurrently, the respectively air levels have been determined. The concentrations in the needles are correlated to atmospheric levels; below an air concentration of 5 ..mu..g/m/sup 3/, the partition ratio is 520, above it is 50.
