The concentration of volatile organic compounds (VOCs) in pig farm air.

The aim of the study was to assess the level of air pollution by volatile organic compounds (VOCs) in a pig fattening house and in its vicinity. Air samples for chromatographic analysis were taken in the fattening house and in the vicinity of the farm. The air quality study shows that the level of organic gaseous pollutants was twice as high in the fattening house as in the atmospheric air. Almost a half of the organic gaseous pollutants determined in the fattening house air are listed among the harmful chemical factors in the work environment. Comparison of the results of the atmospheric air samples taken from the vicinity of the farm with the valid standards also shows very high levels of air pollution in the vicinity of the farm. A mean concentration of the sum of mercaptans, phenol, xylene, 2-methyl-1-propanol, and toluene exceeded their basic values determined in the atmospheric air stated for the calendar year [18].
