Mycotoxins in Indoor Environments

Determination using Mass Spectrometry

CONCLUSIONS

• GC-MSMS analysis of VER and TRID HFB-derivatives in NICI mode and HPLC-MSMS

analysis of STRG, SATG, SATH, GLIO, and AFLAB in positive ESI mode, using triple

quadrupole MS, are very specific and sensitive methods for analysis of indoor

environmental samples.

• The developed integrated HPLC- and GC-MSMS analysis strategy for the combined

analysis of all indicated mycotoxins is convenient and applicable especially

when sample size is small.

• Molds in water-damaged indoor environments, in both sub-tropic and tempered

climatic zones, produce mycotoxins regularly. Mycotoxins were found in settled

dust on surfaces above floor level indicating that mycotoxins from

mold-contaminated building materials can become airborne and inhalable.

• Mycotoxin production or prevalence does not seem to correlate to microscopy

findings, CFU counts, or PCR results for fungi. There is a potential correlation

between fungal biomass and mycotoxin production.

Is mass spectrometry on house expensive?

Yes. A test is available commercially at a cost of approximately $2500
