Nowadays, sanatorium treatment is undergoing a renaissance; however, data on air quality in such premises are scarce. The aim of this study was to characterize microbial air quality at the Szczawnica sanatorium in Southern Poland. The bioaerosol measurements were carried out using a 6-stage Andersen impactor over a period of one year in 3 naturally ventilated sanatorium premises (where different curative treatments took place) and in outdoor air. The indoor and outdoor concentrations of fungal aerosol were always below 1,600 cfu/m(3). With regard to bacterial contamination, the highest concentrations (up to 6,223 cfu/m(3)) were usually noted when the patients were present and underwent curative procedures. Such concentrations crossed the Polish threshold limit values, which suggest that natural ventilation in this type of premises did not ensure the proper air quality; therefore a high-performance ventilation or air-conditioning system should be introduced to provide the "clean" air into the curative treatment rooms. Qualitative evaluation of bioaerosols revealed that the most prevalent indoors were Gram-positive cocci, mesophilic actinomycetes, and filamentous fungi. Analysis of microclimate parameters confirmed that ony relative humidity of the air influenced significantly the levels and composition of microbial aerosols. Hence, the constant control of this parameter should be scrupulously supervised at sanatorium premises.
如今，疗养院治疗正在复兴；然而，关于此类场所空气质量的数据却很匮乏。本研究的目的是对波兰南部什恰瓦尼察疗养院的微生物空气质量进行表征。使用六级安德森撞击器在3个自然通风的疗养院场所（进行不同治疗的地方）和室外空气中进行了为期一年的生物气溶胶测量。室内和室外真菌气溶胶浓度始终低于1600 cfu/m³。关于细菌污染，通常在患者在场并接受治疗程序时记录到最高浓度（高达6223 cfu/m³）。这些浓度超过了波兰的阈值限值，这表明此类场所的自然通风无法确保适当的空气质量；因此，应引入高性能通风或空调系统，以便向治疗室提供“清洁”空气。对生物气溶胶的定性评估显示，室内最常见的是革兰氏阳性球菌、嗜温放线菌和丝状真菌。小气候参数分析证实，只有空气相对湿度对微生物气溶胶的水平和组成有显著影响。因此，疗养院场所应严格监控该参数的持续控制情况。
