From The New York Times: A Brooklyn public school building that had leaking light fixtures will be moved to the top of the list of New York City schools with PCB problems, and the city will replace its lighting very soon, officials say. The building, which houses P.S. 146 Brooklyn New School and Middle School 448 Brooklyn Secondary School for Collaborative Studies, had light fixtures known to contain polychlorinated biphenyls, or PCBs. The city’s plan to replace the lighting has been controversial because of the pace of its timetable. Federal officials and many parents have been pressing the city to move more quickly.
