The event was collected hand wiping samples after incense workers finish
working on incense packing process by using gloves during working. This event was
used to compare the heavy metal concentrations on workers’ hands between after
working by non using gloves and using gloves during working.
The dissolved dye, incense stick, and hand wiping samples of each small
household factory came from the same dissolved dye, which workers mix it every
day. The heavy metal concentration of three sample groups were considered the
average concentration difference between dissolved dye and incense stick, dissolved
dye and hand wiping sample, and incense stick and hand wiping sample. Moreover,
the heavy metal concentrations, which were collected from different events, can
compare the heavy metal concentrations.
