The city’s Health Department announced a 90% drop in the number of young kids with dangerously high levels of lead since 2005 and a 10% decline in the past year.

“We must continue to protect children and prevent lead exposure,” said Health Commissioner Dr. Oxiris Barbot.

The decline is for children under age 6 with blood lead levels of 5 mcg/dL or higher.

Still from January to June, 1,794 youngsters had high blood levels — a far cry from the mayor’s goal for a lead-free New York City.

Most kids were living in buildings owned by private landlords while just 49 resided in public housing.

The announcement glossed over one troubling statistic — since Mayor Bill de Blasio took office in 2014, the number of kids with extremely high levels of lead, 45 mcg/dl and up, has remained relatively constant between 10 and 17 per year.

A Health Department spokesman attributed those figures to kids with behavioral health issues that make them more prone to putting non-food items such as lead paint chips into their mouths. The department connects the families to city nurses who have specialized expertise in reducing elevated blood levels.
