| Summary: | Occupational dust exposure can occur in various settings, including bakeries. A case
study was conducted in an industrial bakery in Perth, Western Australia, to assess
exposure to particulate dust concentration. The factory was separated into three
production zones and an office area which represented as a control zone. Results
indicated that bakery workers in the production zones were exposed to higher ambient
dust particle concentrations compared to those from the office environment. Coarse
particles (>10µm in aerodynamic diameter) were the predominant particle size fraction
measured in all studied areas with the highest median exposure level recorded in the
dough room (0.181 mg/m3
, interquartile range 0.283). High personal concentration
of respirable particles was also measured in the dough room (median 2.26 mg/m3
)
which exceeded the recommended limit of 1.5 mg/m3 and was more than 50 times
higher than the concentration recorded in the office (0.04 mg/m3
). The variation in dust
concentrations between production zones underlines the need of more knowledge about
how aerosol fractions are distributed across the production process. The findings also
suggest that bakery workers are exposed to high dust levels that may increase their
risk of developing respiratory diseases and the decrease of present exposure levels
is imperative. |
