Guest guest Posted February 13, 2004 Report Share Posted February 13, 2004 KC, Thank you for the referral on another post. I am posting this material so everyone can see the problems with opinions and interpretations that can greatly impact human health with regards to " toxic mold " and inhaltion as a route of entry. My first response is to reach Dr. Ritchie Shoemaker if you want to understand mycotoxin producing mold and human health in environmental settings: http://www.chronicneurotoxins.com There has been very little to really understand mold via the inhalation route and subsequent toxicity from the mycotoxins. The best research for mold and health effects comes from food science and veterinary science. I would disregard the statement made by the " American College of Occupational and Environmental Medicine " . It is nothing more than the same regurgitation given by various government agencies. They all say " Don't worry; we don't know what the heck is going-on. We admit to allergic responses because this is not worth any money in court by those scurrilous tort lawyers who expect us to give our best efforts to heal patients " . The people in the government who are in a position of knowledge for pubic health are not in a position to divulge the knowledge of public health since management is often " politically appointed " by those who seek campaign financing from various groups who stand to lose profits created by " standard of care " changes for public health. Both political parties are responsible. The Republicans coddle " big business " (never small business) and the Democrats coddle leftwing nuts that are so removed from reality they bring everything to a grinding halt (including small business). I saw it happen with food safety first and indoor air quality (IAQ) is following the same pattern. Public Health takes a backseat to corporate profit, political favoritism and career building by supporting ideology that is marketable with subsequent job changes (suppression bias). We could all drop dead tomorrow and some group of politicians in the hot seat would use the occasion to " look busy " while creating a regulatory fiasco. Look at the State of Texas and their proposed " 30 fungal structures " (this includes hyphal fragments) limit for surface testing as a means of post testing after remediation. I can get the higher results in any lumberyard in America. THE MISSING FACTS: We are told mold inside structures can be found outside structures and therefore, we would be sick all the time if mold is toxic. This the typical statements made by people with hidden agendas or have a very poor understanding for the physiology of mold in the environment. If you check with the true " taxonomists " who research mold, they will tell you there is a minimum water activity (Aw) for each particular species of mold to grow and a higher water activity for " some " mold species to produce mycotoxins. If you have Stachybotrys (0.94 Aw) growing (even a small area) in an indoor setting, you could have the strong potential for mycotoxin production from various species of Penicillium and Aspergillus which are " active spore releasers " (constantly spewing). Mold in the outdoor air is diluted by the wind and may not get the necessary water activity to produce mycotoxins. The best chance for mycotoxin production is contact with the soil where there is competition with bacteria (which usually wins the battle). This mold is stuck in this wet environment (high water activity) in most cases. Aspergillus fumigatus is an excellent example. Unless a compost pile is vigorously stirred, I just can't see the argument for claiming the mold indoor can't be toxic unless the mold outdoor air is toxic. Most of the studies for the aerobiology of mold and health implications rely on spore trap testing or cultured air samples. The biggest problem with applying this data to health effects is the physiology of mold. When there is heavy growth from high water activity, the biomass of mold is only 3 to 5 percent spores. With exception of PCR (genetic) testing, the other forms of testing rely on spores to identify or culture for future species identification. I have seen a few good consultants and many bad consultants who are just glorified (and overpaid) bean counters. Scientific literature often times has huge gaps of missing knowledge that a consultant must research further if they are to be of any use. The cookie cutter operations don't have time for this investigation. Subsequently, they are the ones who miss important clues and get their tales in a legal crack while leading to economic loss for property owners and needless suffering by occupants. I can't stress enough how important it is to have someone like Dr. Lipsey look for mold and put it in context with toxicology and legal work. He has an amazing knack for finding the best places to get surfaces samples. He is used in the courtroom for a very good reason; he gets results. http:www.richardlipsey.com Regards, Greg Weatherman Aerobiological Solutions Inc. Arlington VA 22202 gw@...
