摘要：Objective. The aim of the study was to assess the impact of a fattening season on the level of airborne chemical and
microbial pollutants in the pig fattening house.
Materials and method. Evaluation of the air composition as well as the microbiological air quality were made during 2 series,
i.e. in the summer and winter period of fattening. Airborne gaseous pollutants were analyzed by gas (organic compounds)
and liquid (inorganic compounds) chromatography methods. Air microbial contamination was determined in compliance
with the Polish Standard PN-EN 13098:2007.
Results. The air/gas composition in the pig unit showed that irrespective of the fattening season, the level of determined
pollutants – especially ammonia, volatile organic compounds (VOCs), including methanethiol and total dust – could have
an adverse effect on the health of swine facility workers. The investigated pig building was found to be a source of chemical
pollutants as well as biological agents. The total bacterial count in 1 m3
of air was 3.6×106
and 4.6×106
cfu, during the winter
and summer periods of fattening, respectively. Gram-positive cocci predominated in both seasons. In the winter, fungi
of the Trichoderma genus were represented equally often. In the summer period, up to 90% of the isolated fungus was
Aspergillus spp.
Conclusions. Workers engaged in swine rearing and production are occupationally exposed not only to a high concentration
of microbial contamination, but also to irritating and odorogenous volatile compounds. Thus, activities directed at the
promotion of health prevention strategies, as well as effective guidelines for safe and hygienic animal housing, should be
implemented.
