摘要

由空气污染引起的疾病的流行,如哮喘和过敏,可归因于生物气溶胶。细菌和真菌是医院感染的主要来源,是造成大多数疾病和死亡的原因。本研究的目的是确定室内和室外真菌浓度的比例,人口和人口密度对真菌浓度的影响以及室内和室外环境之间的关系。本研究采用医院室外、阿瓦士医院普通室内和ICU病房三个站点。选取这些地点于2010年10月至12月对空气传播的真菌进行采样。采用quick take (SKC Inc., PA, USA),基于Andersen法,在2 min内采集样品,流速为28.3 L/min。采样站的三个优势可培养真菌属是曲霉、青霉和枝孢菌。访前可培养真菌总浓度平均值为365.8 CFU m -3,访后可培养真菌总浓度平均值为578CFU m -3。访前ICU室内与室外真菌的比值(I/O)为0.36,院内为0.68。而在ICU和真菌内站,这些比值分别为0.78和0.99。在来访者来访后,室内真菌的浓度明显更高(即使在不允许来访者进入的病房;例如ICU等)。因此,室内真菌的数量受室外真菌浓度和游客人数的影响。

Visiting Hours Impact on Indoor to Outdoor Ratio of Fungi Concentration at Golestan University Hospital in Ahvaz, Iran
Prevalence of diseases originated from air pollution such as asthma and allergies, can be attributed to the bioaerosols. Bacteria and fungi are the main sources of hospital infections, which cause most of the diseases and mortality. The aim of this study was to determine the ratio of indoor to outdoor fungi concentration, the effect of population and people density on fungi concentration and the relationship between indoor and outdoor environment. In this study, three stations were used: outdoor of the hospital, general indoor and ICU wards of the Ahvaz hospital. These locations were chosen for sampling of the airborne fungi from October to December 2010. The samples were collected in 2 min, flow rate of 28.3 L/min using quick take (SKC Inc., PA, USA), based on the Andersen method. The three dominant culturable fungi genera in sampling stations were Aspergillus , Penicillium , and Cladosporium . The average of total culturable fungi concentration before visiting time was 365.8 CFU m -3 and increased to 578CFU m -3 after visiting time. The indoor to outdoor ratios (I/O) in ICU and internal for fungi before visit were 0.36 and 0.68, respectively. However, these ratios in ICU and internal station for fungi after visit were 0.78 and 0.99, respectively. Following the visit of the visitors, the concentration of fungi available indoor was conspicuously higher (even in the wards in which no visitors were allowed; e.g. ICU, etc). Hence the amount of indoor fungi was affected by the concentration of outdoor fungi and visitors crowd.
