QUESTIONS AND CORRECT ANSWERS WITH DETAILED
RATIONALES.
LEAD PAINT
Prepare effectively for the NYC DOHMH Lead Paint Inspector Certification Exam with
this focused study resource. It supports review of lead paint hazards, inspection
procedures, sampling methods, health and safety requirements, lead regulations, and
compliance practices. Use the material to reinforce your technical knowledge, review
key topics, and identify areas that may require additional study. This resource is suited
for lead inspectors, environmental health professionals, housing safety specialists,
and candidates preparing for NYC DOHMH certification examinations.
MULTIPLE CHOICE.
Section 1: Health Effects of Lead Poisoning (Questions 1–20)
What is the main health risk associated with lead paint exposure in children?
A) Allergies
B) Neurological damage and developmental delays
C) Muscle cramps
D) Tooth decay
Answer: B) Neurological damage and developmental delays
Rationale: Lead exposure primarily affects the nervous system, especially
in children. Even low levels of lead in blood can cause learning
disabilities, behavioral problems, and developmental delays. Children
are particularly vulnerable due to their developing nervous systems and
hand-to-mouth behaviors.
At what age are children most vulnerable to lead poisoning?
A) 0–6 years
B) 7–12 years
C) 13–18 years
D) Adults only
, Page 2 of 44
Answer: A) 0–6 years
Rationale: Young children are more susceptible to lead poisoning due to
hand-to-mouth behaviors, higher absorption rates, and developing
nervous systems. Children under 6 years of age are at the highest risk for
lead exposure.
Which of the following is the primary route of lead exposure in children?
A) Skin contact
B) Inhalation of dust
C) Ingestion of lead-contaminated dust or paint chips
D) Drinking distilled water
Answer: C) Ingestion of lead-contaminated dust or paint chips
Rationale: Young children often ingest dust or paint chips from
deteriorated lead-based paint through normal hand-to-mouth behavior,
which is the main exposure route. Lead dust settles on floors and
surfaces where children crawl and play.
Lead exposure in children can result in all of the following EXCEPT:
A) Learning disabilities
B) Behavioral problems
C) Enhanced cognitive development
D) Reduced IQ
Answer: C) Enhanced cognitive development
Rationale: Lead exposure causes neurological damage, learning
disabilities, behavioral problems, and reduced IQ. It does not enhance
cognitive development.
What is the primary target organ system affected by lead exposure?
A) Digestive system
B) Nervous system
C) Respiratory system
D) Muscular system
Answer: B) Nervous system
Rationale: Lead primarily affects the nervous system, particularly in
, Page 3 of 44
children where it can cause irreversible neurological damage. Adults may
also experience neurological symptoms including peripheral neuropathy.
Which of the following is a common symptom of lead poisoning in adults?
A) Enhanced memory
B) High blood pressure and kidney damage
C) Improved vision
D) Increased energy
Answer: B) High blood pressure and kidney damage
Rationale: In adults, lead poisoning can cause high blood pressure, kidney
damage, reproductive problems, and neurological symptoms such as
headaches and memory loss.
Lead dust is most hazardous when it:
A) Is on walls
B) Is in paint chips
C) Is inhaled or ingested
D) Is on windows
Answer: C) Is inhaled or ingested
Rationale: Lead dust can enter the body through inhalation or ingestion,
causing serious health issues. Dust is particularly hazardous because it
can be easily tracked and spread throughout a home.
Friction from painted windows and doors is a common source of lead dust
because:
A) The paint is applied too thickly
B) Friction creates lead dust that can be inhaled or ingested
C) The paint contains added lead for durability
D) The paint chips are colorful
Answer: B) Friction creates lead dust that can be inhaled or ingested
Rationale: Friction on deteriorated lead paint creates dust that can be
inhaled or ingested. Windows and doors are common sources of lead dust
due to friction surfaces.
The developing nervous system of children is more vulnerable to lead
because:
, Page 4 of 44
A) Children breathe faster than adults
B) The blood-brain barrier is not fully developed
C) Children have more lead in their bones
D) Children eat more food
Answer: B) The blood-brain barrier is not fully developed
Rationale: Children's developing nervous systems are more vulnerable to
lead because the blood-brain barrier is not fully developed, allowing more
lead to reach the brain.
Which of the following is a common source of lead exposure in older
buildings?
A) New paint
B) Plumbing pipes and lead-based paint
C) Insulation
D) Plastic molding
Answer: B) Plumbing pipes and lead-based paint
Rationale: Lead-based paint in buildings constructed before 1978 is the
primary source of lead exposure, along with lead plumbing pipes and
fixtures.
The most common route of lead absorption in the workplace is:
A) Ingestion
B) Inhalation
C) Dermal absorption
D) Injection
Answer: B) Inhalation
Rationale: In occupational settings, inhalation of lead dust and fumes is
the most common route of exposure, followed by ingestion through
contaminated hands, food, or cigarettes.
Lead stored in bones can be released back into the bloodstream during:
A) Exercise
B) Pregnancy and lactation
C) Sleeping
D) Eating
