Reaction to Mold odors

Some individuals have very strong reactions to the smells given off by molds. Among humans, there is a high degree of variation in ability to detect these odors, Certain individuals can detect low levels of VOCs, while others can only detect relatively high levels. Those individuals who are particularly susceptible to mold odors may react with headache, nasal stuffiness, nausea or even vomit- ing. Asthmatics often exhibit symptoms when exposed to certain odors.
Toxicities
Molds also produce secondary metabolites such as antibiotics and mycotoxins (a poisonous substance produced by a fungus). Sometimes it is possible to isolate antibiotics from the m olds themselves in order to utilize some of their proper- ties i n fighting infections .Secondary metab 01 is m s are not necessary for maintaining the existence of a mold---either by creating energy or synthesizing structural components, informational molecules or enzymes. They do, however, function to provide molds with advantages over other mold and bacteria and are toxic to certain plant and human cells.
Toxic conditions exist when a human has exposure to these mycotoxins---either through ingesting mycotoxin-containing mold spores or with skin contact to
mold itself. Mycotoxins are nearly all cytotoxic (substances produced by micro-organisms that are toxic to individual cells). which disrupt various cellular structures such as membranes, and interrupt important processes, including protein, RNA and DNA synthesis.

Mycotoxins vary in how dangerous they are for humans. Mycotoxins pose a threat to larger organisms not because they are specifically targeting them, but rather because these large organisms inadvertently come across the byproduct of the competing molds all vying for the same ecological niche. Numerous mold types produce mycotoxins, including some found indoors in contaminated homes and office buildings. Another factor that determines the mycotoxins that are produced by specific molds usually depends on the materials or organisms that they grow on.

It used to be thought that dangerous moIds were primajriIy contaminants in foods. This notion is quickly changing. Recently, researchers have become more concerned with multiple mycotoxins that derive from many types of moId spores growing in moist indoor environments .HeaIth effects from exposures to such moId mixtures can differ from those related to single mycotox ns in controlied laboratory exposures. Although it is difficult to predict how exposure to multiple toxigenic molds can affect an individual (they can synergize the effects), the following provides possible poor health effects from mycotoxin exposure to multiple molds indoors.
