摘要
室内环境热湿参数通过影响室内生物因子（尘螨、真菌、细菌、病毒等）的生长和非生物因子（甲醛、氡等）从建材中的扩散浓度大小,间接影响到人体健康。文章综述了各湿度因子的生物特质和人体危害,以及随空气热湿参数的变化趋势关系,并对各因子进行了健康危害风险度分级评价（Grading of Health Risk Assessment,GHRA）。建议可通过控制室内热湿参数在1个合理的推荐范围,以此降低各种微生物的生长繁殖速度,减少有害化学气体的扩散速率,即把GHRA控制在＂中低风险度＂,达到降低居室内人员患相关病症风险的目的。
Heat and moisture parameters of indoor environment may indirectly influence the human health through affecting the growth of biological organisms such as dust mites, fungi, bacteria, viruses, etc., and the release rate of non-biological pollutants such as formaldehyde, radon, etc. from building materials. Reviews on the biological characteristics of moisture factors and hazards to the human body were given, as well as relations to the changing trend of indoor air hot-humid parameters, whilst a grading of health risk assessment （GHRA） was conducted. To slow down the breeding speed of various microorganisms and to reduce the release rate of harmful chemical gases, controlling indoor hot-humid parameters within a reasonable range was proposed. Thus, the GHRA could be controlled at a ＂medium or low risk level＂ so as to reduce the indoor personnel being in the risk of suffering related illness.
