 Siblings, from front left, Adelisse, 6, Yadier, 3, Joseph, 5, and Gilberto, 8, play together as their mother Yadelis Lopez, back left, keeps an eye on them Friday, June 23, 2017, at their home in Rochester, New York. Ms. Lopez moved to Rochester six years ago and has rented in the city ever since. Her son, Joseph, 5, tested positive for lead at one rental property, though the family has since moved to a house that was cleared by the city. In 2005 the city of Rochester adopted legislation to aggressively lower the number of children exposed to lead in rental housing. Their law is the basis for Toledo's new lead ordinance, which requires rental buildings built before 1978 with up to four units and day-care centers to be certified �lead-safe.�
