The air we breathe indoors is more harmful: research
As the world gets prepared to build smart cities, a new research has highlighted the dangerous effects of indoor pollution on human health and has called for policies to ensure closer monitoring of air quality.
According to Prashant Kumar from the University of Surrey, the research offers insight into “Sick Building Syndrome” and how new smart cities could help combat air quality issues.
When we think of the term “air pollution”, we tend to think of car exhausts or factory fumes expelling grey smoke.
“However, there are actually various sources of pollution that have a negative effect on air quality, many of which are found inside our homes and offices. From cooking residue to paints, varnishes and fungal spores the air we breathe indoors is often more polluted than that outside,” explained Kumar.
In 2012, indoor air pollution was linked to 4.3 million deaths globally, compared with 3.7 million for outdoor air pollution.
Urban dwellers typically spend 90 percent of their time indoors and this has been linked to “Sick Building Syndrome” where people exhibit a range of ill-health effects related to breathing indoor air.
In another paper published earlier in the journal Environmental Pollution, Kumar and PhD student Anju Goel also found that outdoor air pollution was at a high where buildings were located at traffic intersections.
Even where there was low traffic volume, traffic intersections with densely built up surroundings showed twice the concentration than at open junctions.
Exposure to these concentrations showed that ground floor dwellings in these areas were exposed to twice as many harmful particles.IANS
