BACKGROUND Indoor air pollutants (IAPs) cause multiple health impacts. Prioritizing mitigation options that differentially affect individual pollutants and comparing IAPs with other environmental health hazards require a common metric of harm. OBJECTIVES Our objective was to demonstrate a methodology to quantify and compare health impacts from IAPs. The methodology is needed to assess populat...

Exposure to volatile organic compounds (VOCs) has been an indoor environmental quality (IEQ) concern in schools and other buildings for many years. Newer designs, construction practices and building materials for "green" buildings and the use of "environmentally friendly" products have the promise of lowering chemical exposure. This study examines VOCs and IEQ parameters in 144 classrooms in 37...

UNLABELLED In 2001-2003, a team of researchers from the United States and China performed an independent, multidisciplinary review of China's National Improved Stove Program carried out since the 1980s. As part of a 3500-household survey, a subsample of 396 rural households were monitored for particulate matter less than 4 microm (PM(4)) in kitchens and living rooms over 24 h, of which 159 were...

Buildings are expected to provide healthy and comfortable indoor environmental conditions for their users. Such have diverse dimensions, including thermal, visual, air quality, auditory, olfactory aspects. Indoor quality standards, guidelines, codes typically inform professionals in the building design operation phase view of procedural, contractual, legal boundary conditions. Given this critic...

To assess the robustness of various indoor air quality (IAQ) indices, we explored the possible role of reproducibility-induced variability in the measurements of different pollutants under similar sampling and emissions conditions. Polluted indoor conditions were generated by pan frying fish samples in a closed room. A total of 11 experiments were carried out to measure a list of key variables ...

Aims: Indoor air quality (IAQ) has attracted increased attention with the emergence of COVID-19. Ventilation is perhaps area in which most changes have been proposed response to emergency caused by this virus. However, other strategies are possible, such as source control and extraction pollutants. The latter incorporates clean technologies, an emergent respect IAQ. Method: Various treatment te...

To assess risk factors for COVID-19 transmission and address the closure of mass gathering events since March 2020, UK Government ran Events Research Programme (ERP), following which it reopened live in sports, music, culture July 2021. We report rapid post-occupancy evaluation Indoor Air Quality (IAQ) associated long-range airborne conducted Environmental Study ERP. Ten large venues around wer...
