1 Lead-based paint (LBP) 2 Why was lead used so much?
What is the chance of lead dust from
3 4 XRF
high levels of LBP?
Don't know?

, Any varnish, shallac, or coating that contains either-
1.0 mg/cm2 - 0.5 % by weight - 5000 ppm - Older
Lead-based paint (LBP)
instruments could not read accurately at 0.7, so the
lead standard was updated to 1.0
- Floors: 40 μg/ft2 > 10 μg/ft2 (10 μg/ft2 in NY) -
Windows: 250 μg/ft2 > 100 μg/ft2 (50 μg/ft2 in NY) -
Dust sample clearance
Window wells (troughs): 400 μg/ft2 (100 μg/ft2 in NY)
values
- Samples must be at 1 sq ft > 2 sq ft (can be reduced
to 1 sq ft if within 10 μg)
- 400 ppm for playgrounds/children's areas - 1200
ppm for rest of yard - There must be 9 sq ft of soil to
EPA Soil Regulations classify with soil testing - At 5000 ppm, MUST
remediate/abate (remove & replace, paving, or
bioremediation)
- AAS (Atomic Absorption Spectrometry) - Sample is
Lab sampling technique placed into a furnace and vaporized ... light is shone
through to give a quantitative result
- X-ray fluorescence - Utilizes radioactive isotopes
(unstable material trying to reach stability) - Cobalt-57
(half-life of 9 months) and cadmium-109 (half-life of 15
XRF months) are the two sources (where radiation
originates) - Emits gamma rays but will read X-rays
(backscatters) - Ionizing radiation from the removal of
electrons due to interactions with radiation
LBP Hazard ANY condition that causes exposure to lead
a surface-by-surface investigation to determine the
LBP inspection
presence of lead
- Consumer Product Safety Commission - Set a lead
paint standard: cannot contain 0.06% lead by weight ...
CPSC
updated to 0.009% - The commission banned lead-
based paint in 1978
