Several research studies have ranked indoor pollution among the top environmental risks to public health in recent years. Good air quality is an essential component of a healthy environment and significantly affects human well-being. Poor such environments may cause respiratory disease for millions pupils around globe and, current pandemic-dominated era, require ever more urgent actions tackle burden its impacts. The poor could result from management, operation, maintenance, cleaning. Pupils are different segment population adults many ways, they exposed environment: They breathe per unit weight sensitive heat/cold moisture. Thus, their vulnerability higher than adults, conditions affect proper development. However, learning can reduce absence rate, improves test scores, enhances pupil/teacher learning/teaching productivity. In this article, we analyzed literature on schools, with primary focus ventilation, thermal comfort, productivity, exposure risk.

Abstract The COVID-19 restrictions in 2020 have led to distinct variations NO 2 and O 3 concentrations China. Here, the different drivers of anthropogenic emission changes, including effects Chinese New Year (CNY), China’s 2018–2020 Clean Air Plan (CAP), lockdown their impact on are isolated by using a combined model-measurement approach. In addition, contribution prevailing meteorological conditions concentration changes was evaluated applying machine-learning method. resulting multi-pollutant Health-based Quality Index (HAQI) is quantified. results show that CNY reduces average 26.7% each year, while COVID-lockdown measures an additional 11.6% reduction 2020, CAP over 15.7%. On other hand, from 23 January March 7, increase 7.8%. Neglecting thus leads overestimate underestimate effect reductions, respectively. For opposite behavior found, with +23.3%, +21.0%, +4.9%, −0.9% for CNY, COVID-lockdown, CAP, meteorology effects, total these drastic multi-air pollutant-related health risk across China, affecting particularly Northeast China adversely. Importantly, CAP’s highlights effectiveness government’s air-quality regulations reduction.
