This research examined the presence of hazardous materials in chemical workplace field using an integrated chemical/biological monitoring. Chemical workplace field air for volatile organic compounds (VOCs) analysis was collected using a collection tube packed with Tena.x TA adsorbent 400 mg. Workplace field air samples were analyzed by gas chromatography/mass spectrometry (GC/MS). Simultaneously, Tradescantia BNL 4430 clone was exposed in situ to monitor hazardous materials in chemical workplace field. GC/MS analysis showed the presence of various VOCs such as trichloroethylene, toluene, ethylbenzene, (m,p,o)-xylenes, styrene, 1,3,5-trimethylbenzene, and 1,2,4-trimethylbenzene. The results showed that in situ monitoring of VOCs with the Tradescantia-micronucleus (Trad-MCN) assay gave positive results in chemical workplace field and negative response at outdoor air. In conclusion, inhalation of these field air by workers may affect chronic demage to their health by inducing micronuclei formation in Tradescantia pollen mother cells. The combination of chemical/biological monitoring is very effective to evaluate hazardous materials in workplace field and can be alternatively used for screening hazardous materials.
