Mycotoxins in crude building materials from water-damaged buildings
Article Abstract:
Crude building materials from water-damaged buildings may be contaminated with mycotoxins. Cough, irritation of eyes, skin and respiratory tract, headaches, fatigue, and aching joints are potentially caused by such mycotoxins. Aflatoxin precursor, sterigmatocystin, was found on 24% of the 79 bulk sample taken from moldy interior finishes of Finnish buildings with moisture problems. Trichothecenes were found in 19%. Often the presence of fungi thought to produce mycotoxins did not correlate with presence of the expected compounds. When mycotoxins were found some toxigenic fungi usually were found. Identification and enumeration of fungal species i bulk materials are worthwhile for verifying severity of mold damage, but chemical analyses are necessary.

Study of toxin production by isolates of Stachybotrys chartarum and Memnoniella echinata isolated during a study of pulmonary hemosiderosis in infants
Article Abstract:
A case-control study was conducted to examine toxin production by isolates of Stachybotrys chartarum and Memnoniella echinata during a study of pulmonary hemosiderosis in infants occurring in Cleveland, OH, in 1993 and 1994. The isolates from S. chartarum were shown to produce a number of highly toxic compounds and the profiles of toxic compounds from M. echinata were similar. The most distinct difference was the fact that the principal metabolites produced by M. echinata were griseofulvins.

Effect of chlorine dioxide gas on fungi and mycotoxins associated with sick building syndrome
Article Abstract:
The efficacy of chlorine dioxide gas as a fumigation treatment for activating sick building syndrome-related fungi and their mycotoxins was evaluated. Results showed that chlorine dioxide gas at both concentrations completely inactivated all organisms except for Chaetomium globosum colonies, which were inactivated an average 89%.
