ANSWERS GRADED A+
⩥ Microbial Volatile Organic Compounds (MVOC). Answer: What
causes the typical musty or earth odor?
⩥ microbial amplification, meaning incomplete remediation. Answer:
What does a musty odor indicate?
⩥ 2-20 microns. Answer: What is the typical size of mold spores
commonly found in water damaged environments?
⩥ MVOC = Microbial Volatile Organic Compounds // they are
metabolic gases related by actively growing microorganisms // they are
present - when someone is digesting or living. Answer: What are
MVOC's and when are they present?
⩥ high cellulose containing materials and low nitrogen content //
requires a high water activity of greater than 90% ERH (0.9 aw) // must
be saturated for 7 to 12 days. Answer: What conditions are necessary for
Stachybotrys chartarum to grow?
,⩥ toxic chemical compounds // they are found in the cell walls of spores
and hyper. Answer: What do you know about mycotoxins and where are
they found?
⩥ No. Answer: Is Stachybotrys the only mycotoxin producer?
⩥ low (xero) water moisture. Answer: What does xerophilic mean?
⩥ some penicillium aspergillus. Answer: Can you name some xerophilic
fungi?
⩥ 48-72 hour (2-3 days). Answer: How long does it take for certain
molds to colonize under ideal conditions?
⩥ allergenic / infectious / toxigenic. Answer: What are the 3 major
potential health effects from fungal exposure?
⩥ Aspergillosis fumigates // the name of the illness = Aspergillosis.
Answer: Which mold can cause a lung infection and what is the name of
the illness?
⩥ histoplasmosis capsulate // cryptococcus neoformans. Answer: Name
two pathogenic fungi that are associated with bird, pigeon or bat
droppings?
, ⩥ it is a mycotoxins and they like to eat peanuts & spoiled foods.
Answer: What do you know about aflatoxin?
⩥ present in cell walls of gram negative bacteria. Answer: What do you
know about endotoxins?
⩥ kids, elderly and immune compromised individuals. Answer: What
groups of people is the most susceptible population'?
⩥ medical professionals. Answer: What professionals should be
consulted when health effects are perceived with building conditions?
⩥ 9 - shortness of breath // asthma // coughing // runny nose // headaches
// recurrent colds // eye irritation // dizziness // nausea. Answer: List a
number of nonspecific symptoms associated with mold exposure?
⩥ lower body weight // lower immune system. Answer: Why are infants
more vulnerable?
⩥ asthma. Answer: What chronic condition in children is associated with
extended mold exposure?
