Local health officials are offering free inspections for homeowners who might have lead-based paint on their walls.
The Southern Nevada Health District has contracted UNLV scientists to tour southern Nevada homes built before lead-based paint was banned in the U.S.
Researchers estimate 170,000 homes in Las Vegas were built before 1978, when the paint was banned.
The program is just the latest by local officials to protect children from lead, a toxic substance.
A study of lead in Mexican candy by the UNLV School of Public Health led to the candy being banned from store shelves.
Most recently, the discovery of lead paint in thousands of toys from China led to recalls and increased safety standards.
Officials are encouraging people whose homes were built before 1978 to call the health district at 759-1283 to schedule an inspection. The service runs through June.
