batteries. Other uses include the production of ammunition, various
chemicals, and sinkers for fishing and etc.
Lead exposure - correct -answer-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.

Lead Base Paint - correct -answer-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.
Lead has been used in paint for what three main reasons? - correct -
answer-as pigment, to add durability and corrosion control, and as a drying
agent
Lead in surface dust and soil can come from? - correct -answer-
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)
What is the greatest risk of lead exposure that people face? - correct -
answer-Man-made processes and products
Lead in water - correct -answer-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)
Currently, what is the principal industrial use of lead? - correct -answer-
Manufacture of electrical storage batteries
Lead in food - correct -answer-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.
Where does the major exposure to lead for most adults come from? -
correct -answer-The work place
Lead in other sources - correct -answer-Vinyl miniblinds are another
potential source of lead in a residence.
CDC, CPSC, and the public health have identified the following: crayons
(imported from Chile), painted metal playground equipment, pool cue chalk,
calcium supplements (made from bone or oyster shell), some hair dyes
(lead acetate)
What are the major sources of lead exposure for infants and young
children? - correct -answer-Surface dust and soil contaminated with lead
CPSC - correct -answer-Consumer Product Safety Commission
True or False A person may become poisoned through exposure to a
single high-level source of lead or through the cumulative effect of repeated
exposures to low-level sources of lead. - correct -answer-True
Health effects of lead exposure - correct -answer-The three systems
where the effects are most dangerous are: the central and peripheral
nervous system. the cardiovascular system (including the blood forming
system), and the kidneys.
Exposure to high concentrations of lead can cause: retardation,
convulsions, coma, and death (sometimes)

What is the main cause of lead contamination in drinking water? - correct -
answer-Corrosion of lead-containing materials in household plumbing
Acute vs Chronic exposure - correct -answer-acute - exposure for short
time at high levels
chronic - exposure to low or moderate levels over a long period of time
True or False Hot, acidic, 'soft' (low in dissolved solids) water is the least
corrosive towards lead; cold, alkaline, 'hard' water is most corrosive. -
correct -answer-False
INSPECTION IS A CRITICAL FIRST STEP IN SOLVING THE LEAD
PROBLEM IN HOMES THROUGHOUT THE UNITED STATES. THE
PRIMARY SKILL FOR LEAD INSPECTOR TO DEVELOP IS? - correct -
answer-Documentation of information
In what year did Congress ban the use of lead-containing materials above
specific percentages in public water supply systems and in any plumbing
providing drinking water connected to public water systems? - correct -
answer-1986
Lead base paint is found more often in pre world war housing units than
those built since 1940 although all housing constructed prior to 1978 is at
risk - correct -answer-1978
Besides leaded gasoline, what are other sources of lead contamination in
air? - correct -answer-Emissions from smelters and battery factories and
combustion of oil, coal, waste oil and municipal wastes.
Aldo lead based paint is found as often and homes of well to do as the
poor, studies prove that the lower income families are proportionately
affected. This apparent discrepancy maybe due to the lower income
