The present study was aimed at evaluating microbiological contamination of air in Ciechocinek and Inowrocław - Polish lowland spa towns. Additionally, the impact of open-air inhalatoria on the quality of air was evaluated.
Air samples were collected seasonally in the urban areas, in the recreation areas and in the vicinity of inhalatoria in both towns using impaction. The numbers of mesophilic bacteria, staphylococci, hemolytic bacteria and actinomycetes were determined on media according to the Polish Standard PN-86/Z-04111/02. The number of moulds was determined on media according to the Polish Standard PN-86/Z-04111/03.
While the highest numbers of microorganisms were noted at the sites located in the urban areas, the lowest numbers were noted in the vicinity of the open-air inhalatoria. In all the investigated air samples the values of bioaerosol concentrations were below the recommended TLVs (≤ 5000 CFU×m(-3) for both bacteria and fungi in outdoor environments). Location of the sampling site was invariably a decisive factor in determining the number of microorganisms in the air.
The aerosol which is formed in the open-air inhalatoria has a positive influence on microbiological air quality. Owing to a unique microclimate and low air contamination, Ciechocinek and Inowrocław comply with all necessary requirements set for health resorts specializing in treating upper respiratory tract infections.
本研究旨在评估波兰低地温泉城镇切霍齐内克和伊诺弗罗茨瓦夫空气中的微生物污染情况。此外，还评估了露天吸入治疗区对空气质量的影响。
采用撞击法，在两个城镇的市区、休闲区以及吸入治疗区附近季节性采集空气样本。根据波兰标准PN-86/Z-04111/02，在培养基上测定嗜温细菌、葡萄球菌、溶血细菌和放线菌的数量。根据波兰标准PN-86/Z-04111/03，在培养基上测定霉菌的数量。
虽然在市区的采样点微生物数量最多，但在露天吸入治疗区附近微生物数量最少。在所有调查的空气样本中，生物气溶胶浓度值均低于推荐的阈限值（室外环境中细菌和真菌均≤5000 CFU×m(-3)）。采样点的位置始终是决定空气中微生物数量的决定性因素。
露天吸入治疗区形成的气溶胶对微生物空气质量有积极影响。由于独特的微气候和低空气污染，切霍齐内克和伊诺弗罗茨瓦夫符合专门治疗上呼吸道感染的疗养胜地的所有必要要求。
