Since indoor air pollutants can adversely affect human health, it is important to have real-time indoor air quality assessment/monitoring system that can help not only in the improvement of indoor air quality but also help in detection of leaks, spills in a work environment and boost energy efficiency of buildings by providing real-time ...
Unlike low-cost monitors, which are carried from place to place, static monitors continuously sample and measure the air quality in a particular, urban location. Public places such as busy railroad stations sometimes have active air quality monitors permanently fixed alongside platforms to measure levels of nitrogen dioxide and other pollutants ...
For indoor environments such as offices or gyms where the principal source of CO 2 is human respiration, rescaling some easier-to-measure quantities such as volatile organic compound (VOC) and hydrogen gas (H 2) concentrations provides a good-enough estimator of the real CO 2 concentration for ventilation and occupancy purposes.
Passive or "diffusive" air sampling depends on meteorological conditions such as wind to diffuse air pollutants to a sorbent medium. Passive samplers, such as diffusion tubes, have the advantage of typically being small, quiet, and easy to deploy, and they are particularly useful in air quality studies that determine key areas for future continuous monitoring.
Diffusion tubes are widely used by local authorities for monitoring air quality in urban areas, [2] in citizen science pollution-monitoring projects carried out by community groups and schools, [3] [4] and in indoor environments such as mines [5] and museums. [6]
Although ventilation is an integral component of maintaining good indoor air quality, it may not be satisfactory alone. [6] A clear understanding of both indoor and outdoor air quality parameters is needed to improve the performance of ventilation in terms of occupant health and energy. [7]
Household air pollution (HAP) is a significant form of indoor air pollution mostly relating to cooking and heating methods used in developing countries. [1] Since much of the cooking is carried out with biomass fuel , in the form of wood , charcoal , dung , and crop residue , in indoor environments that lack proper ventilation, millions of ...
The alliance works to supply information, guidelines and knowledge on the indoor environmental quality (IEQ) in buildings and workplaces, [4] and to provide occupants in buildings and workplaces with an acceptable indoor environmental quality (indoor air quality (IAQ), thermal conditions, visual quality, and acoustical quality) and help promote ...
