Mold .Assessment .
(FL) .- .A .process .performed .by .a .mold .assessor .that .includes .the .physical .sampling .and .detailed .eval
uation .of .data .obtained .from .a .building .history .and .inspection .to .formulate .an .initial .hypothesis .abo
ut .the .origin, .identity, .location .and .extent .of .amplification .of .mold .growth .greater .than .10 .square .f
eet.
Mold .Remediation .
(FL) .- .The .removal, .cleaning, .sanitizing, .demolition .or .other .treatment, .including .preventative .activiti
es, .of .mold .or .mold-contaminated .matter .greater .than .10 .square .feet .that .was .not .purposely .grown
.at .that .location.
Mold .Assessment .
(NY) .- .An .inspection .or .assessment .of .real .property .that .is .designed .to .discover .mold, .conditions .th
at .facilitate .mold, .indicia .of .conditions .that .are .likely .to .facilitate .mold .or .any .combination .thereof.
Mold .Remediation .
(NY) .- .Conducting .the .business .of .removal, .cleaning, .sanitizing, .or .surface .disinfection .of .mold, .mold
.containment, .and .waste .handling .of .mold .and .materials .used .to .remove .mold .from .surfaces .by .a .b
usiness .enterprise, .including .but .not .limited .to, .sole .proprietorships. .Mold .remediation .for .the .purp
oses .of .this .article .shall .not .include .remediation .of .the .underlying .sources .of .moisture .that .may .be .
the .cause .of .mold .that .requires .expertise .not .specific .to .acts .authorized .under .this .article.
Project .
(NY) .- .Means .mold .remediation, .mold .assessment .or .mold .abatement .of .areas .greater .than .ten .squ
are .feet, .but .does .not .include .(a) .routine .cleaning .or .
(b) .construction, .maintenance, .repairs .or .demolition .of .buildings, .structures .or .fixtures .undertaken .f
or .purposes .other .than .mold .remediation .or .abatement.
Sanitization .- .Reduction .of .the .microbial .population .on .an .inanimate .object .to .levels .judged .safe .by .
public .health .standards; .usually, .the .object .is .cleaned .with .an .antimicrobial.
,Remediation .- .The .act .of .removing .damaged .construction .materials .when .said .materials .are .irretriev
able .or .nonsalvageable. .Such .remediation .should .be .done .with .precaution .due .to .health .concerns .fo
r .the .occupants .and .the .contractor .who .is .doing .the .work.
What .is .Mold? .- .Molds .are .fungi .which .may .grow .on .environmental .surfaces, .in .porous .materials, .o
n/or .within .living .organisms .and .in .decaying .organic .matter.
The .Kingdoms .- .1. .Animals .
2. .Plants .
3. .Protozoa .
4. .Fungi .
5. .Bacteria .
6. .Viruses
Fungi .- .Mold .is .a .particular .type .of .fungus. .
Fungi .are .a .distinct .and .unique .group .of .organisms .that .are .classified .into .an .individual .kingdom.
Most .Common .Indoor .Fungi .- .• .Aspergillus .
• .Cladosporium .
• .Penicillium .
• .Asper/Pen
When .Molds .Grow .- .Most .fungi .are .composed .of .microscopic .filaments .called .HYPHAE ., .which .bran
ch .to .eventually .form .a .network .of .hyphae, .called .a .MYCELIUM .
(colony). .The .mycelium .extends .over .or .through .whatever .substrate .the .fungus .is .using .as .a .source .
of .food.
Digestive .Systems .of .Molds .- .Fungi .secrete .digestive .fluids .that .decompose .the .substrate, .making .nu
trients .available. .
When .the .environmental .conditions .are .right,
.molds/fungi .have .all .the .food .they .need .to .grow .and .colonize.
Toxic .By-Products .
(Mycotoxins) .- .• .Large .group .of .toxins .produced .by .some .fungi, .located .on .or .in .the .spores. .
• .Toxins .can .be .cancer .causing .and .suppress .the .immune .system. .
• ."Secondary .Metabolites" .of .mold .growth .are, .essentially, .the .by-products .of .mold .growth.
,Toxic .Molds .- .Stachybotrys .Chartarum .primary.
.Just .because .it's .black .doesn't .mean .it's .Stachybotrys .
.Isolated .primarily .from .water .damaged .building .materials .and .cellulose .contents .(discard) .
.Mycotoxin .producer, .toxic .to .many .
.Requires .an .ongoing .water .source. .
.Secondary .metabolite .of .this .is .Trichothecene, .a .mycotoxin. .
(Some .other .obscure .molds .produce .this .same .bi-product.) .Other .water .damage-
related .molds .may .be .toxic .including .Fusarium, .Chaetomium, .Trichoderma .and .Memnoniella. .
Additional .molds .found .to .have .toxins .include .Aspergillus .and .Penicillium, .Cladosporium .and .more. .
Mycotoxins .are .not .always .produced.
What .are .VOCs? .- .VOCs .are .invisible .gases .that .are .emitted .from .solids .and .liquids .found .in .the .ho
me, .such .as .building .materials, .cooking .sources, .gasoline .and .fuel, .air .fresheners,
.paints/varnishes, .drycleaning, .laser .printers, .carpeting, .adhesives, .cleaning .solutions, .and .many .othe
r .sources. .These .chemicals .can .build .up .in .houses, .especially .in .the .winter .and .summer .months .whe
n .homes .are .generally .closed .up. .Repeated .exposure .to .VOCs .can .cause .blurred .vision, .headaches, .
nausea, .dizziness, .coughing, .lethargy, .burning .eyes, .respiratory .irritation, .skin .rashes, .reduced .lung .f
unction, .respiratory .illness, .concentration .difficulties, .depression, .and, .in .extreme .cases, .loss .of .cons
ciousness .and .suffocation. .Higher .exposure .can .lead .to .liver .damage, .kidney .and .central .nervous .sys
tem .irregularities. .Some .VOCs .can .cause .cancer.
What .are .MVOCs? .- .MVOCs .are .gases .
(chemicals) .produced .by .actively .growing .mold. .Just .as .humans .expire .gases, .so .do .molds. .These .ch
emicals .can .be .monitored .to .determine .the .level .of .actively .growing .mold .in .the .house. .A .Home .Air
.Check .measurement .is .an .excellent .way .to .determine .the .level .of .mold .growing .in .a .house .- .even .
behind .walls. .This .is .possible .because .Home .Air .Check .is .a .chemical .analysis .of .the .air, .and .chemica
ls .move .more .freely .through .a .house .than .mold .spores .
(particulates) .which .can .be .trapped .by .walls .and .thereby .go .undetected. .When .mold .levels .are .elev
ated .and .there .is .chronic .exposure .in .the .home, .some .individuals .can .experience .negative .health .eff
ects, .or .worsening .of .existing .illnesses, .that .could .run .the .gamut .from .mild .to .serious. .These .health
.effects .could .include .allergies, .skin .irritations, .asthma, .respiratory .infection, .and .toxic .poisoning. .In .
addition, .individuals .with .suppressed .immune .systems .may .be .particularly .vulnerable .to .illnesses .cau
sed .by .mold .contamination.
Volatile .Organic .Compounds .- .VOC .- .Chemicals .that .easily .evaporate .into .the .air .
.Some .VOC's .have .industrial .origins, .e.g. .housekeeping .products .but .sourcing .is .often .difficult .becau
se .these .come .from .most .building .components .and .many .contents .in .a .home .or .building.
, Microbial .Volatile .Organic .Compounds .- .mVOC .- .Produced .during .fungal .growth .as .a .waste .by-
product .so .they .elevate .primarily .when .a .mold .is .in .an .active .state. .
.Their .production .is .dependent .on .the .substrate .and .environmental .conditions .and .are .easily .detect
ed .even .when .no .visible .mold .is .present.
Conditions .Needed .for .Mold .Growth .- .Temperature .(ideal .- .40°F .to .100°F) .
.Moisture .(ideal .- .H2O .or .RH .<%40-60%>) .
.Nutrient .base .(ideal .- .less .organics)
How .Do .Molds ."travel" .? .- .Like .other .IAQ .contaminants, .mold .spores .and .mycotoxins .travel .in .the .a
ir .with: .
.Moisture .(H2O .or .RH) .
.Convection .(dryer .heat .rising) .
.Air .Movement .(pressure) .
.Air .Infiltration .(inside .or .outside) .
.From .Outdoors .(drifting .in .behind .us)
What .Changed? .- .Energy .crisis .of .1970's .
.600% .rise .in .energy .costs .
."Building .Energy .Thermostat .Settings" .(BETS) .-"Thermostat .police" .
High .cost .of .air .conditioning .outside .air .reduces .outside .air .requirements .and .therefore .produces .a .
"toxic .soup" .
Energy .efficient .practices .created .early .shut-downs .and .late .start-ups .('coasting') .
Variable .Air .Volume .
(VAV) .systems .became .a .common .modification .to .recycle .air .more ."Value .engineering" .emerges .whi
ch .lead .to .devalued .projects .and .buildings .
We .begin ."sealing .our .homes .with .deadly .precision" .says .one .Doctor.
New .building .materials .use .polymers, .resins, .formaldehyde .and .other .emitted .chemicals, .off-gassing .
