Microbial quality and physical-chemical properties of recreational spas were surveyed to investigate the health aspect of the spas' water. A total of 195 samples were collected from pools and springs of the spas in five sites from Ardebil Province of Iran. The effects of an independent factor defined as 'condition' and its component sub-factors (i.e., sampling point, location, and sampling date) on microbial quality and physical-chemical properties of the spas were studied by applying path analysis. The influence of physical-chemical properties on microbial quality was also considered. The percentage of samples exceeding the ISIRI (Swimming pool water microbiological specifications (vol 9412), Institute of Standards and Industrial Research of Iran, Tehran, 2007) limits for Staphylococcus (spp.) was up to 55.8 in the springs and 87.8 in the pools, 58.1 and 99.2 for HPC, 90.7 and 97.8 for total coliform and fecal coliform, and 9.3 and 34.4 for Pseudomonas aeruginosa, respectively. There were significant differences between the pools and springs for both physical-chemical properties and microbial quality. From the path analysis, sampling point was the most effective sub-factor of 'condition' on both the physical-chemical properties and microbial quality. Among the physical-chemical properties, water color had the most enhancing or additive influence on microbial pollution, while EC indicated a reducing or subtractive effect.
对休闲温泉浴场的微生物质量和理化性质进行了调查，以研究温泉浴场水质对健康的影响。从伊朗阿尔达比勒省五个地点的温泉浴场的水池和泉水中总共采集了195个样本。通过路径分析研究了定义为“条件”的独立因素及其组成子因素（即采样点、位置和采样日期）对温泉浴场微生物质量和理化性质的影响。还考虑了理化性质对微生物质量的影响。超过伊朗标准与工业研究学会（ISIRI，《游泳池水微生物规范》（第9412卷），伊朗德黑兰标准与工业研究学会，2007年）葡萄球菌（属）限值的样本百分比，在泉水中高达55.8%，在水池中高达87.8%；异养菌平板计数分别为58.1%和99.2%；总大肠菌群和粪大肠菌群分别为90.7%和97.8%；铜绿假单胞菌分别为9.3%和34.4%。水池和泉水在理化性质和微生物质量方面均存在显著差异。通过路径分析，采样点是“条件”对理化性质和微生物质量最具影响的子因素。在理化性质中，水的颜色对微生物污染具有最强的增强或累加影响，而电导率则显示出减少或消减作用。
