This finding could also possibly be due to the higher urban outdoor air pollution concentrations from vehicle generated pollutants although other causes unrelated to air quality such as post nasal discharge may be a possibility.
The combustion process in an incinerator inevitably generates pollutants such as carbon monoxide (CO).
The study addresses the pollutants emitted by burners on the stove, but the process of cooking foods, for example by frying or stir frying, also generates pollutants.
But environmental advocates say the production process generates pollutants and note that the box has a useful life of only a few minutes, while it lingers for decades when it is littered or dumped in a landfill.
In addition, current widely used air distribution systems on airplanes dilute internally generated pollutants by promoting air mixing and thus impose risks of infectious airborne disease transmission.
Contrasting effects of the dilution of indoor generated pollutants and the energy efficiency of heating and ventilating air conditioning systems (HVAC) for indoor air quality (IAQ) and thermal comfort were studied for 10 Kuwaiti residences.
Ventilation is the primary factor affecting indoor-to-outdoor transport of indoor generated pollutants.
Incense burning produces continuous smoke, generating pollutants, such as toxic gases and chemical particles, including polycyclic aromatic hydrocarbons, carbon monoxide, benzene, and isoprene that easily accumulate indoors, especially under inadequate ventilation [ 33].
However, both theoretical evidence and limited empirical data indicate that feasible modifications in ventilation rates can decrease or increase indoor concentrations of some indoor generated pollutants associated with asthma by ≤ 75% (IOM 2000).
