roughly 90% of family housing units in the nation's housing authorities. - Correct Answer How
common is lead pollution?
Paint, varnish, shellac, or other coating on surfaces that contain 1.0 mg/cm^2 or more of lead or
0.5% or more lead by weight. - Correct Answer Lead-based paint
Any condition that causes exposure to lead-contaminated dust, lead-contaminated-soil, or lead-

impact surfaces that would result in adverse human health effects as identified by the EPA
Administrator under TSCA section 403. - Correct Answer Lead-based paint hazard
a surface-by-surface investigation to determine the presence of lead-based paint. A report is
then issued that identifies if there is lead-based paint present and where it is located. - Correct

and is within three feet or the floor or ground (e.g., window sills, railing, and the edges of stair
treads) - Correct Answer Accessible surface
An interior or exterior surfaces that is subject to abrasion or friction (e.g., certain window, floor,
and stair surfaces) - Correct Answer Friction surface
An interior or exterior surface that is subject to damage from repeated impacts (e.g., certain
parts of door frames) - Correct Answer Impact surface
The primary purpose of the Guidelines is to guide people involved in identifying and controlling
lead-based paint hazards in housing. - Correct Answer HUD Guidelines
1 milligram per square centimeter (1.0 mg/cm^2) using the XRF analyzer or 0.5% (or 5,000
parts per million) using laboratory analysis methods - Correct Answer What is lead-based paint
Atomic absorption spectrometry - Correct Answer AAS
American Association for Laboratory Accreditation - Correct Answer A2LA
American Society for Testing and Materials - Correct Answer ASTM
Center for disease control and prevention - Correct Answer CDC
Code of federal regulations - Correct Answer CFR
Inductively coupled plasma atomic emission spectrometry - Correct Answer ICP-AES
National Institute for Occupational Safety and Health (Dept. of Health) - Correct Answer NIOSH
Occupational Safety and Health Administration (Dept. of Labor) - Correct Answer OSHA
The chemical symbol for lead - Correct Answer Pb
Trisodium phosphate - Correct Answer TSP
resource conservation and recovery act - Correct Answer RCRA
Nearly all of the lead in the human environment results from human activities. Once lead is
mined, processed, and introduced into the human environment it is a potential problem forever.
No current technology will destroy it or make it permanently harmless. However, exposures to
lead can be controlled.
,The occupational hazards of lead were first reported in 1713 by Bernardo Ramazzini, who
described lead intoxication in potters working with lead glazes.
In 1913, Dr. Alice Hamilton, an American occupations health doctor, wrote about painters and
the hazards of their work. - Correct Answer History of Lead Use
As a pigment, to add durability and corrosion control, and as a drying agent. - Correct Answer
Why was lead used in paint?
The principal industrial use of lead is in the manufacture of electrical storage batteries. Other
uses include the production of ammunition, various chemicals, and sinkers for fishing and etc. -
Correct Answer Sources of environmental lead contamination
The major exposure to lead for most adults comes from the work place (inhalation). Surface
dust and soil contamination with lead are the major sources of lead exposure for infants and
young children (ingestion). (Children: drinking water [primarily from leaded solder, brass fittings
and fixtures, and service lines] can contribute to lead poisoning) - Correct Answer Lead
exposure
The amount of lead-based paint in housing is significant - approximately 64 million (pre-1978)
private U.S. residences contain at least some lead-based paint.
Children ingest lead-based paint by normal hand-to-mouth activity. Young children absorb a
significantly higher percentage of ingested lead than adults. Lead absorption is increased by
malnutrition and poor diet. - Correct Answer Lead paint
Weathering and chipping of lead-based paint, scraping and sanding of lead-based paint in
preparation for refinishing, renovations that break surfaces painted with lead-based paint,
abrasion and/or impact on doors and windows, atmospheric fallout from the combustion of
leaded gasoline that was deposited prior to the phase-down in use, factory emissions, dust and
dirt that is carried into the home on shoes and clothing (especially from factories or construction
sites or by pets) - Correct Answer Lead in surface dust and soil can come from?
Lead-contaminated drinking water also contributes to the overall level of exposure - from as little
as 5 percent to more than 50 percent of a child's total lead exposure. (NAETI Exam: 20%
contribution) - Correct Answer Lead in water
Contamination from containers with lead solder, lead glaze, or other materials with lead, by
airborne lead from industrial or automobile emissions deposited on to crops or water, by uptake
into food crops from lead in soil or pesticides applications, and doing transportation or
processing.
A phase-out of lead solder in cans began in the late 1970s.
, Food containers: lead oxide is sometimes used to manufacture glazes for protecting ceramics
and etc. - Correct Answer Lead in food
Vinyl miniblinds are another potential source of lead in a residence.
