their clothes. It was found that mean urinary mercury levels
and duration of work, hours worked per day, days worked per
week, work position, use of PPE (mask, gloves, and trousers),
eating snacks or drinking water during work, washing hands
before lunch, and washing hands after work, were significantly
different, at p < 0.05 (Table 4). Workers who had worked > 5
years had significantly higher urinary mercury levels than those
who had worked < 5 years (p < 0.001). Workers who had
worked ≥ 8 hours per day and 5 days per week had significantly
higher urinary mercury levels than those who had worked < 8
hours per day and 5 days per week (p = 0.002 and p < 0.001,
respectively). The results indicated that the median urinary
mercury levels among work positions were significantly different
(p < 0.001). Workers who used mask and/or gloves had
significantly lower urinary mercury levels than those who did
not. Workers who always ate snacks had significantly higher
urinary mercury levels than those who sometimes ate them.
Workers who always washed their hands after work had significantly
lower urinary mercury levels than those who sometimes
did so
