The April issue of CM/Cleaning & Maintenance Management® magazine is now available online, featuring part three of Dr. Michael Berry''s Science-based steps of the cleaning process series.
Berry states that most allergic reactions are caused by particles >10 µm (less than 10 microns in size).
He notes that, commonly referred to as VOCs when existing as a gas, organic pollutants come from indoor sources, including furnishings, building materials, tobacco smoke, fires, fuels, solvents, pesticides and cleaning products.
Berry adds that the atmosphere in the average U.S. residence contains various pesticides with concentrations 10 to 100 times greater than ambient outdoor concentrations.
According to Berry, a healthy body is fairly efficient at expelling particles in the 2.5-10 µm (micron) range.
Michael D. Berry, Ph.D., was chairman of the Science Advisory Council for the Cleaning Industry Research Institute (CIRI) in 2006. The information contained in this article was extracted from Dr. Berry''s papers and presentations at CIRI''s 2007 Cleaning Science Conference and Symposium. His entire paper and PowerPoint presentation, as well as those of other symposium presenters, are available at www.ciri-research.org.
