Studies on human exposure to indoor air pollution reveal that indoor environments could be at least twice as polluted as outdoor environments. Indoor air pollution has not received as much attention than outdoor air pollution, despite an adult spending now most of the time indoors as a result of the global shift in the economy from the manufacturing sector towards the service and knowledge-based sectors, which operate in indoor office environments. Additionally, the health threats caused by a long-term exposure to indoor air pollution have become more apparent over the last decades as buildings are progressively sealed against the outside climate conditions to obtain heating and cooling energy cost savings and in response to stricter safety guidelines. Currently there is not a single technology that can efficiently provide a complete and satisfactory purification of indoor air. Biological systems for improving indoor air quality are promising, but challenges need to be examined to properly address the bioavailability of low pollutant concentrations, guarantee microbial safety, and incorporate CO₂-removal. This study presents the recent research advances in biological indoor air purification methods as a ‘green’ alternative to physical–chemical methods, with emphasis on current challenges and opportunities it can provide for improving Indoor Environment Quality, building energy cost savings and improvements on indoor comfort and well-being.

用于改善室内空气质量的生物系统的最新进展

关于人类暴露于室内空气污染的研究表明，室内环境的污染程度至少是室外环境的两倍。尽管全球大多数经济体从制造业向服务业和知识型产业转移，但室内空气污染没有室外空气污染引起那么多的关注，尽管现在成年人大部分时间都花在室内。室内办公环境。此外，在过去的几十年中，随着建筑物逐渐与外界气候条件隔离以节省供热和制冷能源成本并响应更严格的安全准则，由长期暴露于室内空气污染引起的健康威胁变得更加明显。当前，还没有一种技术可以有效地提供对室内空气的完全和令人满意的净化。改善室内空气质量的生物系统是有希望的，但是需要研究挑战以正确解决低污染物浓度的生物利用度，保证微生物安全性以及吸收一氧化碳。_2-移除。本研究介绍了生物室内空气净化方法作为物理化学方法的“绿色”替代方法的最新研究进展，重点介绍了它可以为改善室内环境质量，节省建筑能源成本和改善室内舒适度提供的当前挑战和机遇。和幸福。
