Dermal exposure is the main route that the dyeing colors contact human body. Thus hand wipe method is employed to collect samples of heavy metals on workers’ hands. Thirty-five small household factories are selected from 100 small household factories in the village for sample collection (Jaipieam, 2008). Each small household factory has the whole process of incense production, but the workers who responsible to incense packing step are chosen randomly to collect samples by gauze wiping technique. Hand wipe samples were collected for three times per a small household factory.
