THE BRONX - Parents, teachers and lawmakers are protesting at City Hall today against PCB levels inside the city's public schools.

Residents say they're protesting the city's 10-year plan to rid public schools of lead and cancer-causing PCBs. 

At least three Bronx schools have tested positive for the toxic chemicals in the past year.

Lawmakers say they are proposing a bill that would establish a three-year timeline for all lighting fixtures leaking PCBs in Bronx schools to be replaced.

Despite that the city says it will re-examine the plan in 2014, supporters of the bill say the city isn't moving fast enough.
