Indoor air pollutants include particulate matter, biological pollutants and over 400 different chemical organic and inorganic compounds, whose concentrations are governed by several outdoor and indoor factors. Prevention of pollutant is not always technically feasible, so the implementation of cost-effective...
According to the WHO, the primary reasons for the 3.8 million annual deaths due to household air pollutant exposure include pneumonia (27%), stroke (18%), ischaemic heart disease (27%), chronic obstructive pulmonary disease (20%) and lung cancer (8%). The most vulnerable group includes ...
There were no significant relationships between mean weekly change in air pollutant levels and concurrent weekly changes in forced vital capacity (FVC), forced expiratory volume during the first second (FEV1), University of California San Diego Shortness of Breath Questionnaire (UCSD-SOBQ), or visua...

Countries globally trade with tons of waste materials every year, some of which are highly hazardous. This trade admits a network representation of the world-wide waste web, with countries as vertices and flows as directed weighted edges. Here we investi
It is worth mentioning that ventilation does not directly affect occupant health, but the rate of ventilation affects indoor air pollutant concentrations that, in turn, modify the occupants’ health. Previous studies have reported that indoor radon and thoron concentrations are related to environmental ...
Such behaviours can include smoking; the use of air fresheners; the frequent Conclusions The IAQ is one of the factors that can expose people to almost any toxic chemical, in concentrations higher than in the outdoor air. During sleeping, people breathe passively and are exposed for several ...
To keep a balance between maximising the amount of air, which is drawn in to reduce air pollutant concentrations generated from indoor sources and minimising the ingress of outdoor originating air pollutants such as PM, especially in urban areas, can be challenging (NASEM, 2022). However, proper...
The causes include rapid urbanization and population growth, with emissions from diverse pollutant sources—cookstoves, brick kilns, other industries, power plants, and transport. However, major gaps in our understanding remain due to the scarcity of air quality monitoring stations. 2. Persistent ...
Although the IAQ in the chamber was controlled using filters and manipulation of fresh air ventilation rate, pollutant levels can fluctuate based on the occupants of the room and outdoor air quality. To account for this, the analysis of IAQ effects on creativity score was performed in two parts...
