摘要：The purpose of the study was to assess Korean farmer!ˉs exposure level to
dust in pig buildings and dust emissions by investigating airborne concentrations of total
and respirable dust. Five main types of pig buildings operating currently in Korea were
selected. For area air sampling, 30 sites per each building type were visited during spring
(March ¨C May) and autumn (September ¨C November) seasons. For personal air sampling
concentrations of total and respirable dust were measured for 2 ¨C3 hours, during cleaning
the pig building before the end of the daily shift, by attaching air sampling equipment
near to the farmer!ˉs breathing zone. Measurement were taken for 8 hours, e.g. average
daily work time (09:00¨C17:00), at 0.5 m above the? oor at three locations on the central
alley in the pig building. Emission rates of total and respirable dust were estimated by
multiplying the mean concentration of total and respirable dust measured near the air
outlet by the mean ventilation rate, and expressed either per area or per pig of live weight.
The ranges of farmer!ˉs exposure level to total dust and respirable dust in the pig buildings
-3 -3
were estimated as 0.6¨C6.7 mg
and 0.3¨C3.5 mg , respectively. The pig buildings
operated with a deep-litter bed system showed the highest dust level while the naturally
ventilated pig buildings with slats represented the lowest dust level (p<0.05). Emission
-1 -2 -1 -2
rates ranged from 35¨C400 mg m for total dust and from 4¨C40 mg m for respir-
able dust, respectively, indicating a similar pattern for the distribution of exposure level.
Korean farmers!ˉ exposure level to dust in all the pig buildings investigated was below the
-3
exposure limit value equal in Korea equal to 10 mg m
, while it exceeded the threshold
limit values (TLVs) established in other developed countries. In comparison with previ-
ous studies performed in other countries, mean exposure level in the pig buildings of
Korea was generally lower for total dust and higher for respirable dust based on the area sampling method.
