  • Mold has always been present


How can you be exposed to mold l.jpg
How can you be exposed to mold?

  • Damaged or disturbed moldy material

  • Inhaling spores

How does mold grow?



Slide8 l.jpg
Should I be concerned about mold in indoor environments?Mold should not be permitted to grow and multiply indoors.

  • When this happens, health problems can occur and building materials, goods and furnishings may be damaged.


How do i tell if i have a mold problem l.jpg
How do I tell if I have a mold problem?

  • Investigate, don’t sample. Use your eyes to look for mold growth and by using your nose to locate the source of a suspicious odor, signs of excess moisture or the worsening of allergy-like symptoms


How can mold affect your health l.jpg
How can mold affect your health?

Health outcomes include:

  • Allergies

  • Infection

  • Irritation

  • Toxicity

How should mold be cleaned? should we see a physician?

  • Clean mold as soon as it appears

  • Melinda Ballard 32 million

  • Ed McMahon’s dog

  • Houston 2001

  • Continues to be a large growth industry

  • The media loves a good story

excessive reporting by building occupants of one or more of the following symptoms:

  • dizziness

  • burning eyes

  • watery eyes

  • sinus difficulty

  • flu-like symptoms


What is stachybotrys chartarum l.jpg
What is Stachybotrys chartarum? should we see a physician?

  • Black mold?

  • Toxic mold?

  • Killer mold?

  • Death mold?

  • Fatal fungus?

  • $ Mold is Gold? $

  • Cleveland 1994



How can stachybotrys chartarum affect your health l.jpg
How can Stachybotrys chartarum affect your health? your home?

  • There is inadequate evidence to support the conclusion that exposure to mycotoxins in the indoor environment is causally related to symptoms or illness among building occupants.

  • There is inadequate evidence to support recommendations for greater urgency in cases where mycotoxin-producing fungi have been isolated.

    AIHJ Sept/Oct 2001


Stachybotrys chartarum l.jpg
Stachybotrys chartarum your home?

  • Does this take stachybotrys off the hook?

    • It does make mycotoxins

    • It can cause disease in animals

    • A transfer mechanism needs to be identified

    • It is less than 1% of indoor fungus

  • Conclusion

    • Mycotoxins are real

    • Fungi should all be treated with respect



Impact on human health l.jpg
Impact on human health your home?

  • Depends on:

    • Species involved

    • Metabolic products being produced by these species

    • Amount of exposure

    • Duration of individual exposure to mold parts or products

    • Specific susceptibility of those exposed

      • Harriet Amman, Washington State DOH


Impact on human health27 l.jpg
Impact on human health your home?

  • Health effects generally fall into 4 categories:

    • Allergy

    • Infection

    • Irritation (mucus membrane & sensory)

    • Toxicity


Impact on human health28 l.jpg
Impact on human health your home?

  • Allergy

    • Molds are just one of several sources of allergens (mites, cockroaches, pet dander)

    • Most common response to mold exposure

      • Atopic individuals (genetically capable of producing an allergic response)

      • Respiratory exposure or skin contact

    • About 20% of population suffer from allergic rhinitis

    • About 10% allergically-induced asthma


Impact on human health29 l.jpg
Impact on human health your home?

  • Infection

    • Not common

    • In susceptible individuals (immune compromised from disease or drugs)

    • Aspergillus are known to be opportunistic pathogens

      • A fumigatus – aspergilloses, and allergic fungal sinusitis


Impact on human health30 l.jpg
Impact on human health your home?

  • Irritation

    • From the VOCs

    • Mucus membrane irritation from the pungent or unpleasant primary metabolic processes.

    • The moldy or musty odors are commonly produced from the secondary metabolites

    • Additionally, sensory response – trigeminal nerve responds to pungency not odor, by causing avoidance reactions


Impact on human health31 l.jpg
Impact on human health your home?

  • Toxicity

    • Secondary metabolites

      • Antibiotics

      • Mycotoxins (competitive advantage over bacteria)

    • Causation link has not been shown



Hot topic in tort and construction litigation l.jpg
Hot Topic in Tort and Construction Litigation your home?

  • Large verdicts

  • Large number of mold claims

  • Media attention


Why litigation l.jpg
Why Litigation? your home?

  • Energy conservation – hinders escape of moisture

  • Building materials with organic sources (paper)

  • Improper building design (roofs/windows)

  • HVAC systems

  • Improper protection of building material during construction


Fed state regs l.jpg
Fed & State Regs your home?

  • NIOSH says there are:

    • No accepted standards for mold sampling in indoor environments or for analyzing and interpreting the data in terms of human health

    • Molds are everywhere – if you test you will find mold

    • It is not known what quantity is acceptable in indoor environments with respect to human health


No standards yet l.jpg
No Standards Yet your home?

  • Why are there no standards?

    • Most studies have tended to be based on baseline environmental data, rather than human dose-response data

    • Individuals have different sensitivities to molds, so setting standards and guidelines for indoor mold exposure is difficult and impractical


Lawsuits have claimed l.jpg

  • Compromised immune systems

  • Acute abdominal pain

  • Central nervous system damage

  • Memory loss

  • Cancer

  • Study health effects of mold – Rhode Island

  • Mold abatement guidelines for schools – Tennessee

  • Abatement and Remediation licensing – Texas

  • How insurance claims are handled - Texas


Toxic mold protection act l.jpg
Toxic Mold Protection Act your home?

  • California – 2001

    • Develop PELs to molds in indoor environment

    • Assess the health threat posed by the presence of mold

    • Set standards for the assessment, identification, and remediation of mold

    • After limits are set, they are to be reviewed within a 5 year time period

      Lack of funding has made this bill ineffective
