What we need to know about indoor air pollution

AIR pollution, whether inside or outside, has a significant impact on our heart, lungs, brain, and neurological health.

A team of Washington State University researchers led by Tom Jobson, a professor in the department of civil and environmental engineering, found a surprisingly high level of pollutants, including formaldehyde and possibly mercury, in carefully monitored homes. They said these pollutants vary through the day and increase as temperature rises.

The researchers said people should recognize that they can expose themselves to much higher emission rates in their homes. “These emissions come from a variety of sources, such as building materials, furniture, household chemicals products, and people activities like cooking,” Jobson said.

His team added that one way to clear harmful chemicals is to have ventilation. They said trying to make homes more airtight could worsen the problem.

Researchers said having the air-conditioner on or opening the window during the afternoon can reduce the impact of chemicals on people.

An islander interviewed by this writer said a concrete house is very hot from the afternoon until about seven in the evening. Although she wants to turn on the air-conditioner, she doesn’t want to pay an expensive power bill. So she usually leaves the door and windows open, but this allows insects and other unwanted creatures to enter her house.
