The aim of the study was to monitor the gaseous pollutants in farm pigs, rabbits and mink air. Among the identified impurities obtained with the highest concentration of methane was observed in the air of domestic rabbits (33.04 mg/m3). In contrast, the highest level of ammonia and hydrogen sulfide was found in breeding pigs. The concentrations of gaseous impurities exceeded the permissible safe value for animals. The air samples also showed significant amounts of toluene and p-oksylenu (BTX). The highest level of BTX compounds was reported in the air from pigs (19.80 mg/m3), while the lowest value was observed in the air samples taken from the rabbit farm.
