The results of a study assessing the level of airborne contamination in intensive broiler breeding facilities are presented. The content of corpuscular particulates of various origin (dust, bacteria, fungi), ammonia and carbon dioxide was determined. The investigations were conducted in a poultry house on a family farm in the area of moderate continental climate during spring 2006. The air concentration of bacteria ranged from 1.7 × 104 to 2.2 × 105 cfu/m3, of fungi from 9.8 × 103 to 8.5 × 104 cfu/m3, of dust from 1.8 to 4.8 mg/m3, and of ammonia from 4 to 27.47 ppm. Total dust and fungi concentrations measured at the end of fattening period were almost identical to the initial ones, whereas the concentrations of bacteria and ammonia showed a sinusoidal rise from the beginning to the end of fattening period. In general, the analyzed air pollutants reached relatively high levels in the mid-fattening period and also show significant differentiation between fattening periods as demonstrated by t-test yielding statistical significance at a level of P < 0.05.
