Considering the alarming rise in the rate of asthma and respiratory diseases among school children, it is of great importance to investigate all probable causes. Outside of the home, children spend most of their time in school. Many studies have researched the indoor environmental quality of primary and secondary school buildings to determine the exposure of school children to indoor air pollution. However, studies of very young children in nurseries are scarce. Unlike at elementary schools or universities, children in nurseries are more vulnerable due to their physiology, inability to articulate discomfort and to adapt their behaviour to avoid exposures. This article reviews current studies on the indoor environment in nurseries. It summarizes air pollution levels and related environmental and behavioural factors in nurseries that have been reported in the literature. Additionally, exposure to indoor air pollution and related potential health outcomes are examined. This review concludes that indoor air pollution in nurseries often exceeds current guidelines, and designers and policymakers should be made aware of the impact on the health and wellbeing of children in nurseries. Proper interventions and guidelines should be considered to create a healthy indoor environment for nursery children.

Practical application: Previous IAQ assessments have mainly focused on indoor temperatures and CO₂ levels. Data on comprehensive monitoring (including PMs, NO₂, O₃ and other pollutants) of indoor air quality of nurseries are scarce. Particularly in the UK, studies about indoor air quality in nurseries have not been founded. This paper categorized relevant articles according to the focus of the study, to provide evidence to a better understanding of current indoor air quality in nursery environments.

考虑到小学生哮喘和呼吸系统疾病的发病率上升惊人，因此调查所有可能的原因非常重要。在家里，孩子们大部分时间都在学校里度过。许多研究已经对中小学建筑物的室内环境质量进行了研究，以确定学童暴露在室内空气污染中的程度。但是，很少对托儿所中的幼儿进行研究。与小学或大学不同，托儿所的儿童由于其生理机能，无法表达不适和适应其行为以避免暴露而更加脆弱。本文回顾了托儿所室内环境的最新研究。它总结了文献中已报告的托儿所中的空气污染水平以及相关的环境和行为因素。此外，还检查了暴露于室内空气污染和相关的潜在健康后果的可能性。这项审查得出的结论是，托儿所的室内空气污染经常超过现行准则，因此应使设计者和决策者意识到托儿所对儿童健康和福祉的影响。应该考虑采取适当的干预措施和指导方针，为托儿所儿童营造一个健康的室内环境。设计者和决策者应了解托儿所对儿童健康和福祉的影响。应该考虑采取适当的干预措施和指导方针，为托儿所儿童营造一个健康的室内环境。设计者和决策者应了解托儿所对儿童健康和福祉的影响。应该考虑采取适当的干预措施和指导方针，为托儿所儿童营造一个健康的室内环境。

实际应用：先前的室内空气质量评估主要集中在室内温度和CO ₂水平。苗圃室内空气质量的综合监测（包括PMs，NO ₂，O ₃和其他污染物）数据很少。特别是在英国，尚未建立有关托儿所室内空气质量的研究。本文根据研究重点对相关文章进行了分类，为更好地了解托儿所环境中当前的室内空气质量提供了证据。
