All of us are aware about the pollutants outdoors, but what about indoor pollution? We tend to keep our homes warm and energy efficient, but sometimes it can lead to pollutant levels three times higher than the outdoor environment.
New studies reveal that gas appliances can produce higher level of pollutants. Living in an apartment with gas appliances means you are more exposed to pollutants, which will be more than walking through a congested city center.
While measuring the air quality inside and outside of some residential buildings researchers have arrived at this conclusion.
And the end result showed that nitrogen dioxide (NO2) levels in urban apartments were three times higher than the concentrations measured outside. Average particle concentrations in these apartments were higher than the levels set by the government for outdoor air quality in both London and whole of England.
The manner at which we make our homes airtight to reduce heating costs make us highly exposed to indoor pollution, which in turn influences our body health. The team specifically looked for pollutants like carbon monoxide (CO), nitrogen dioxide (NO2), volatile organic compounds (VOCs) and solid particles small enough to penetrate into the lungs (2.5 microns in size or smaller, known as PM2.5).
These pollutants can cause respiratory or cardiovascular problems in humans. There is always a concern about the air quality outdoors, but a person spends 90% of time indoors and it requires some concern.
