Mayor Bill de Blasio unveiled a new initiative Monday aimed at eradicating lead levels in children.

The plan is called 'Lead Free NYC.' Under the plan, the city wants to require annual inspections of apartments in one- and two-family and test all NYCHA apartments. Officials also want to reduce the amount of lead in paint and dust that sparks remediation to the lowest level of any major U.S. city.

Officials pointed out that 97 percent of children with elevated lead levels are living in private housing.

Mayor de Blasio says since 2005, the number of kids younger than 6 with elevated blood levels of lead has declined 90 percent. He credits the work of strong laws and public health officials.

"This is a vision-zero approach," says de Blasio. "This report today literally is the plan to end once and for all lead point poisoning in New York City. There is no city in this nation that has put together a more aggressive approach."

Last year, the Bronx had the highest violations issued with 4,500 and Brooklyn came in at the second highest with around 4,000.
