AB The influence of the type of farming on harmful gas exposures to carbon dioxide (CO2), ammonia (NH3) and hydrogensulfide (H2S) was assessed from the perspective of animal welfare and occupational hygiene. Summer data of H2S, NH3and CO2 concentrations and of environmental parameters were collected from 31 farms. The indices of exposure for longterm exposures to NH3 suggest the lowest acceptability of exposure was observed on poultry farms. CO2 had the highestdependence on production activity. For H2S, no differences were found based on farming activity. Both the stocking densityand volume of air available affected the daily exposure and the index of exposure to CO2. Significant differences were observedbetween hourly CO2 concentrations, depending on the level of activity inside the building. A positive correlation was foundbetween gas concentrations and temperature increase. All values of daily and short-term exposures were below exposurelimit values, which suggests that exposure conditions were appropriate for workers’ health during the measurement period.Analysis of the working hours and average hourly concentration of gases during the times of day, with presence of workersinside the farm buildings, revealed significant differences for CO2.
