Volatile organic compounds (VOCs) and formaldehyde are ubiquitous in indoor environment. 16 Inhalation of VOCs can cause irritations, difficulty breathing, and nausea, and damage the central 17 nervous system as well as other organs. Formaldehyde is even a carcinogen. Removal of VOCs and 18 formaldehyde is thus critical to control indoor air quality (IAQ). Photocatalytic oxidation has been 19 d...

Volatile organic compounds (VOCs) are ubiquitous in indoor environments. Inhalation of VOCs can cause irritation, difficulty breathing, and nausea, and damage the central nervous system as well as other organs. Formaldehyde is a particularly important VOC as it is even a carcinogen. Removal of VOCs is thus critical to control indoor air quality (IAQ). Photocatalytic oxidation has demonstrated f...

As people spend 90% of their time indoors, it was necessary to improve indoor environmental quality enhance human productivity. Indoor consists air (IAQ), thermal, visual, and acoustic comfort. However, only a few studies have investigated the combined effects IAQ noise. During after COVID-19 pandemic, portable cleaner is often used in buildings reduce concentration particles air, but also gene...

Indoor air quality (IAQ) is crucial for the wellbeing of university students. Yet, IAQ in student residences highly variable and challenging to monitor. This work first monitor residence with a low-cost sensor network.

Air pollutant exposure in workplace environments has been associated with health and cognitive outcomes of workers. While green building certification programs have instrumental promoting indoor air quality (IAQ), the present literature indicates inconsistent evidence. Recent emergence proliferation WELL program that prioritizes human evoked new questions about its effectiveness relation to IAQ...

There are thousands of indoor ice rink arenas in the United States, Canada, and Europe. The combustion byproducts from the fuel powered ice resurfacing equipment impose a potential health risk to both athletes and spectators. A field survey of ten ice rink arenas in Greater Boston and Halifax, Nova Scotia indicates that the fuel type used by the resurfacer as well as the air exchange rate, the ...

Abstract Background Indoor air quality (IAQ) is a concern in kindergartens as children spend much of their time there. Yet, there shortage biological indicators needed for assessing IAQ. Thus, this study evaluated IAQ using transplanted lichen Usnea misaminensis indicator. Methods Lichen samples, collected from Bukit Larut, Perak, Malaysia, were exposed to indoor and outdoor environments an urb...
