The main purpose of this article is to investigate the possibility of
detection of the level of mycotoxins in air samples by a surface
plasmon resonance (SPR) immunobiosensor. Air samples of 0.25-0.5
m3 volume collected using a special miniature air pump device were
passed through 20% acetonitrile as an absorption liquid, and 20 μl aliquots of the extract
were analyzed by an SPR immunobiosensor. Comparative analyses by the determination of
T2 mycotoxin content were carried out in air and in grain samples upon dispersion in a
phytotron. Moreover, mycotoxin content was investigated also under field conditions in air
and in vegetable matrix, in the absence and presence of Fusarium fungi, and results were
shown to have similar characteristics: the level of mycotoxins detected in air samples
correlated with that in grain samples. Thus, results of air-borne mycotoxin detection were
correlate with mycotoxin levels detected in environmental samples and may used for
screening purposes.
