Organophosphorus insecticides are common pollutants of the citrus oils. Unknown phosphorated compounds, different from organophosphorus pesticides, were detected during GC analyses of citrus oils; the chromatographic profile was similar to a triarylphosphate mixture. Standard mixtures of triarylphosphates were analyzed and mass spectra were obtained; the results showed that the contamination was due to triphenylphosphate and tritolylphosphate isomers essentially. The contaminants were found to probably originate from contact of the oils with plastic materials from which they leached on oil storage.

Abstract
Organophosphorus insecticides are common pollutants of the citrus oils. Unknown phosphorated compounds, different from organophosphorus pesticides, were detected during GC analyses of citrus oils; the chromatographic profile was similar to a triarylphosphate mixture. Standard mixtures of triarylphosphates were analyzed and mass spectra were obtained; the results showed that the contamination was due to triphenylphosphate and tritolylphosphate isomers essentially. The contaminants were found to probably originate from contact of the oils with plastic materials from which they leached on oil storage.File in questo prodotto:
