The debate between Mold Illness sufferers and their skeptics remains a hot one. Mold Illness occurs when a person gets exposed to large amounts of mold, in most cases over a significant amount of time.
"But mold is everywhere," is technically a valid and logical response from any person subject to the Semmelweiss Reflex.
I won't even deep dive into the most obvious response to this, which is that the mold in question is more than likely a toxic mold species. These include species from Stachybotrys, Aspergillus, Chaetomium, or several other species on the growing list of toxic molds.
Instead, my point is that -- given the state of anthropogenic pollution -- "mold is everywhere" is an antiquated line of reasoning that fails to consider the dynamic interactions between pollution and our environment. Even mold species that are not classifiably toxigenic will metabolize and release virtually whatever pollution they are eating, as that has been their role in the ecosystem long before humans existed.
For example, let us compare a piece of OSB to a stump in the woods. Just like the stump, the OSB has wood in it, but it also has added chemicals such as the adhesives used, which contain Formaldehyde. Formaldehyde is a carcinogenic irritant that requires a Haz-Mat team if spilled in a hospital operating room, yet it is found at ostensibly low levels all around us.
Once the OSB and tree stump get wet, the beginning stages of mold growth will take place. Like a network of spiderwebs, the mycelium grows into the wood and materials just like plant roots into the soil.
The Fruitbody is the part of the fungus that grows aerially (in the air above the growing medium.) This part releases spores and metabolites into the air, using the nutrients it has absorbed from within the growing medium. Since the mycelia have toxic chemicals available in the OSB, they will metabolize those available materials for use and release them into the air.
The stump in the woods does not have chemicals readily-available to digest, and therefore does not cause illness in humans or animals.
It is already common knowledge that anthropogenic pollution is a leading cause of illness like cancer. Using logic to take this one step further, even skeptics must concede that this pollution may be causing further damage beyond its biopersistence stage.
Studies have also shown that mold absorbs metallic particles into its flesh. "One species could even cope with a coating of silver, known to be toxic to microorganisms..." -NewScientist.com
Scientists have found that mold spores carry nanoparticles on them.
Mold itself can synthesize nanoparticles from materials including metals. It makes sense, since it is the job of fungi to break down everything into smaller pieces. Various microorganisms are tasked with synthesizing various nanoparticles for scientific and medical purposes. However, nanoparticles pose well-known health threats to the human body.
As a result of microbes like fungi, bacteria, and actinomycetes, anthropogenic pollution has a second opportunity to enter the human body and cause illness.
Nanoparticles have been found to cause allergic-type reactions in animals and humans, a condition known as Complement Activation Reaction Pseudo Allergy (CARPA). CARPA presents with symptoms of "pulmonary hypertension with or without various degrees of systemic hyper- or hypotension, tachy-or bradycardia, arrhythmia, blood cell and inflammatory mediator changes and skin rash." -From the European Journal of Nanomedicine
Yes, mold is everywhere. But it is what the mold is consuming and releasing into the air that can make it so toxic to humans and pets. From what we can observe in medical history, moldy stumps in the woods do not generally cause illness. In fact, historically mold toxicity was not a health issue despite the billions of wood dwellings that humans built throughout time.
Mold illness rates have skyrocketed along with the arrival and increased use of OSB and other chemical-treated materials in new construction.
"Mold is everywhere" may have been a valid argument centuries ago, before our environments became so heavily polluted. However now we can no longer justify applying outdated logic to our toxic, modern world.
The Pandora's Box of pollution has been opened, and we are yet to discover all of the ways that we are inadvertently poisoning ourselves -- and the rest of the food chain -- with chemical, biochemical, and nanoparticle pollution.
