Black Mold - Stachybotrys Chartarum - Black mold issues are something everyone should be aware of and know how to combat. Search through any news source and you will see that toxic mold is a common cause for school closings. If the school board will go through such measures to eradicate the problem then we should be just as cautious. It is also important to remember that like all other types of fungus, there are some people who may be more sensitive to the effects of black mold. People who have allergies, respiratory disease or any type of immune suppressing disease should be especially wary of this toxic mold.
