Title Trichothecene mycotoxins in the dust of ventilation systems in office buildings
Bibliographic information 1993, Vol.65, No.2, p.113-117. 25 ref.
Abstract The presence of trichothecene mycotoxins in dust samples from the air conditioning systems of four office buildings in Montreal, Canada, was determined. The buildings were known to cause sick building syndrome among their occupants. Analyses of the dust samples by thin-layer chromatography yielded four kinds of trichothecene mycotoxins. The results were confirmed by high-performance liquid chromatography. This method appeared to be more sensitive while positive colour reaction on thin-layer chromatography plates using 4-(p-nitrobenzyl)pyridine proved less costly and less time-consuming. It was found suitable for qualitative detection of trichothecene mycotoxins in dust extracts.
