It is known from the relevant research that workers engaged in wood-related jobs are exposed tohealth risks, such as occupational asthma, which could be induced by wood dust, or the exposure toaflatoxin or endotoxins. Therefore, this experiment chose a wood processing environment to conductan investigation of mycotoxin exposure. The experiment used the Andersen six-stage viab1e sampler,Biosampler, AGI-30 and SKC aluminum cyclone with PC filter paper to evaluate the concentration ofthe fungi and mycotoxin in the wood processing plant.

The results showed that in the working environment of a plant, Aflatoxin B1, Fumonisins andZearalenonewere detected in the wood dust desorption solution, and the concentrations were allrelatively higher than the air samples. Among these, Aflatoxin B1 had the highest concentration, withthe range between 97.2 and 510.4 ng/g (wood dust).

At present, there are no complete standards on the content limit of mycotoxins or the exposurelimit on wood dust in the working environment. It is recommended that standards be imposed in thefuture to prevent the increase of diseases.
