It is not always the fire itself that is the great danger, it is the tiny particles of soot that are produced by the fires that can be a greater hazard to health. These particles can be up to 10 times worse for human health than similar particles from other sources. Overall, California...

a Global population headcounts exposed to different levels of air pollution risk. b Number of people and share of population exposed to air pollution, by region. c Top ten countries with highest population exposure to unsafe PM2.5 levels. Hazard categories are defined based on estimated average ...
with adverse outcomes on people’s health (Vlachokostas et al.2011). According to the last World Health Organization (WHO), more than 80% of people living in the urban context are subjected to air quality levels above the emission limits regarding air pollution. ...

(reliability) and, further, must consider the hazards that may arise, especially in a new and untested technology that is selected. Risk is a function of likelihood that the hazard will in fact be encounter, so the air quality manager is also tasked with predicting the adverse implications ...
Local ambient air quality is reported online using the air quality index (AQI), which communicates whether the relative air quality and air pollution level in a given area is healthy or unhealthy. Maps of local AQI values use color-coded air hazard levels (green, yellow, orange, red, purple...
Owing to the effect on people, livestock, and materials, air pollution is a global hazard. To this end, stakeholders have taken on the challenge of quantifying the environment with the use of tools and eventually using the data produced to provide solutions to the problems. However, low-cost...
The air quality index is a metric used for reporting relative outdoor air quality and air pollution levels in a given area. Maps of local AQI values are updated every 8 or 24 hours, depending on the pollutant, and provide an indication of the groups of p
The results revealed that indoor concentrations of PM2.5 and CO2 significantly contribute to the total hazard ratio, indicating the need to reduce their levels below reference values. The study also found that the ventilation system significantly affects indoor air quality, and concentrations of TVOC,...
