Since people spend about 90 percent of their time indoors, exposure to these ‘stealth pollutants’ can be harmful to human health.
Atlanta, GA (PRWEB) August 18, 2011
Air Quality Sciences, Inc. (AQS) announced today its new service for measuring ultrafine particle (UFP) emissions from indoor sources. UFPs are very small, typically less than 100 nanometers (or about 1/1000th of a human hair). By virtue of their size, UFPs can be inhaled easily and travel deep into the human lung. Health studies indicate a strong correlation between UFP exposure and respiratory and cardiovascular illnesses, as well as a heightened allergic inflammation that can exacerbate asthma.
“Sources of ultrafine particles are numerous and include many natural and manmade sources,” explains Tony Worthan, chief operating officer of AQS. “Even with a plethora of outdoor UFP sources, including vehicle emissions, studies suggest that indoor sources are even greater for a typical non-smoking suburban consumer. These indoor sources include our everyday activities— cooking, cleaning, using electronic devices, burning candles and spraying aerosols. Since people spend about 90 percent of their time indoors, exposure to these ‘stealth pollutants’ can be harmful to human health.”
According to Worthan, AQS will partner with product manufacturers to evaluate UFP emissions from their products.AQS has the capability of coupling its technically advanced environmental chambers, rated as high performance clean rooms, with the latest UFP measurement technologies. This allows manufacturers to study their products under controlled, yet realistic, building conditions for precise results. Studies have already begun to measure UFPs from operating office printers, burning candles, and fragranced cleaners. “Understanding the potential for UFP release is an important step in a manufacturer’s product safety evaluation,” Worthan adds.
AQS has just released a new white paper entitled, “Ultrafine Particles: Why All the Concern About Something So Small?” This educational paper examines UFPs and their common indoor sources, human exposure risks, health implications, and control measures. It also discusses the airborne contaminant criteria of certain third-party electronic product standards, such as those from Blue Angel, EcoLogo, GREENGUARD, EPEAT (IEEE), UL Environment, and JEITA. The white paper is available in its entirety, free of charge, from the Aerias-AQS Indoor Air Quality Resource Center at http://www.aerias.org. Read more by clicking on this direct link.
