AND SOLUTIONS
◉ What does RRP do?
Answer: - Renovation, Repairing, and Painting program - Provided
enforcement to Title X in 2010 ... $37,500 fines for violation - Dust
sampling technicians can only sample for RRP projects
◉ What must you do if a pre-1978 site is not tested?
Answer: Presume lead-based paint.
◉ Where is LBP still allowed?.
Answer: Commercial purposes/boats
◉ What are the major industrial uses of lead?.
Answer: Present - Electrical batteries - Chemical additives Past -
Paint additive - Gasoline additive (now in soil ... doesn't permeate
quickly, so sample TOP portions (12 in)) - Solder/pipes
◉ What are the common pathways of contamination?.
,Answer: - For children under 6, hand-to-mouth contact from DUST ...
lead tastes sweet (pica is the term for consumption of non-food
items) - For adults, occupational exposure (take-home lead ... pets
can contribute too)
◉ Chronic vs. acute exposure.
Answer: - Chronic: low dose, long period - Acute: high dose, short
period
◉ How do you treat lead poisoning?.
Answer: - Chelation therapy - Binding agents attach to lead in the
blood, allowing it to be excreted - Chelating agents cannot
distinguish lead from minerals, so the therapy causes
demineralization - Done at a blood lead of 45 μg/dL
◉ Where does lead contamination in water come from?.

abatement
◉ T/F: Poor diet can exacerbate lead absorption.
Answer: True. You want high calcium, iron, and Vitamin C.
◉ True/False: The association between lead dust and blood level
has been scientifically proven.
Answer: True
◉ Where does a house have the highest lead levels with respect to
soil sampling?.
Answer: Dripline
◉ What are friction, impact, and mallable surfaces?.
Answer: - Friction: rub (floors) - Impact: smash (doors, stairs) -
Mallable: edible ... protrude more than 4 in
◉ What is the chance of lead dust from high levels of LBP?.
Answer: Twice as high
◉ How much does water contribute to lead exposure for the average
2-year old?.
