Monitoring Human-Based Indoor Air Pollution

A team of engineers at Purdue University, Indiana, recently undertook a study on indoor air pollution. The engineers used sensors to monitor four open-plan office spaces.

Also, they tracked the flow of air in the ventilation system.

Finally, they used a ‘nose’ to measure levels of indoor pollution caused by humans.

The ‘nose’ allowed the engineers to ‘sniff’ out compounds contained in human breath.

The team of engineers noted that isoprene and other volatile compounds lingered in the air. Also, they noticed that these compounds lingered in office long after people left.

Indoor Air Pollution

The engineers made another insight:

The higher the amount of occupants in a room, the higher concentration of these compounds.

Assistant professor of Civil Engineering, Brandon Boor said:

“If we want provide better quality for workers to improve their productivity, it is important first to understand what’s in the air and what factors influence the emissions and removal of pollutants.’

Also, the team discovered the creation of new, more toxic compounds.

They noted that ozone particulate produced by internal combustion engines and power plants, could mix with compounds released from peeling an orange to produce new, tiny particles.

These particles are so small they can reach the deepest part of a person’s lungs. Moreover, they can pose a toxic risk to building occupants.

Chemicals emitted from deodorants, makeup and hairspray can also be harmful. These chemicals play a part in outdoor pollution. This is because ventilation systems can carry them outdoors.

These findings are increasing the pressure for employers to allow home working.

Effective ventilation can help you protect employees from the risks of indoor air pollution. At OMNI, our sensors and transmitters can help you improve workplace ventilation.
