Guest guest Posted October 31, 2001 Report Share Posted October 31, 2001 I am doing a story for Wired regarding SBS and a Japanese company's recent claim to have developed new materials that help eradicate SBS. SAITAMA — Japanese researchers have developed a new construction material that uses wood charcoal to absorb chemical substances and odors thought to be linked to sick building syndrome (SBS), they said Monday. The material, made from charcoal powder mixed at different heating temperatures, is aimed at virtually eradicating toxic chemical substances used in construction materials for houses, according to Sanei Corp in Tsuru, Yamanashi Prefecture and Kikuo Oikawa, a professor at Niigata College of Pharmacy in Niigata Prefecture. (Kyodo News) Do you believe that these materials could help eradicate SBS? Do you believe the company is merely out to make more money? I appreciate your opinions in advance.

Guest guest Posted November 1, 2001 Report Share Posted November 1, 2001 , I assume you are new to this board, perhaps having found it by running a search. Numerous previous postings have addressed the topic you are asking about. The value of the charcoal treatment depends on the particular problem causing a building to be sick. When this phenomenon first started getting attention in the late 70's, early 80's, the problem was most often thought to be volatile organic compounds (VOCs) originating from construction materials- adhesives, carpet, waterproofing tar, etc. Sometimes this was true. But,as time passed, it has been realized that many problems are caused by bio-aerosols, fungal and bacterial (legionaire's disease is the most famous bacterial problem). Perhaps this charcoal can absorb some of the VOCs produced by fungi. But this allows fungal spores to spread without the characteristic odor warning, stimulating allergic sensitization in susceptible people, often people with no previous history of allergy, leading most certainly to asthma or sinus problems, and quite possibly to fatigue, digestive disorders, muscle pain, and possibly memory problems. The mold cells themselves cause SBS moreso than the odor compounds associated with mold. Mold cells are not absorbed by the charcoal. For reference, read the EPA or NIOSH web page on building mold. Or try " Bio-Aerosols, Assessment and Control " , from American Conference of Governmental Industrial Hygienists. You might also want to contact a catalyst manufacturer, such as Cabot Chemicals. You just might find that charcoal is not terribly effective at absorbing VOCs in humid environments, such as the basements where problems often originate. This suggests these claims may be more hype than substance. Good luck in further researching your article. Gil Vice Cincinnati Ohio ----Original Message Follows---- From: stencil@...
