PCBs in schools

Celebrating Children’s Health Month

By Maureen O’Neill

So why are you reading this?  Are you interested, worried or want to take action?  For you then, here’s some good and bad news.

Let’s do the good first.  There is a wealth of information on every children’s health topic you can imagine.  Chances are, if you are reading this, you’ve already been exposed to topics like lead, methylmercury, PCBs and goodness knows what else.  If you haven’t and want an overview, you can check out the websites of EPA, CDC, NIEHS and many others.

I am a professed info junkie and although I try, I can’t keep up with everything.  I don’t know anyone who can.  So I focus in on what I need to know and be sure I’m looking at some of the topical sources to see what’s going on.  My own favorite for this is Environmental Health News which lands in your mailbox every day.

Are you a parent or someone worried about a child’s exposure and what it means?  Do you need to get professional advice?  We have a Pediatric Environmental Health Specialty Unit serving the region (NJ, NY, Puerto Rico and the USVI) at Mt. Sinai.  These are docs who specialize in environmental health topics and you can get a free phone consultation.  The PEHSU also provide clinical consultation and education for health care professionals, public health officials, and community organizations with concerns regarding children’s environmental health.  See more here.

Here’s the not so good part.  There’s a lot of information on children’s health out there, of varying quality, and many of the topics have emerging science.  That means that frequently there aren’t good clear yes/no answers that we all want to have.  So, what to do?

I think the smartest thing is to be protective of your kids, have fun with them and practice the best tips I know.  Go to http://www2.epa.gov/children to see how to help your kids breathe easier, protect them from lead poisoning, keep pesticides and other toxics away from children and protect them from carbon monoxide, contaminated fish, radon and other environmental hazards.  We can’t protect children from everything, but if you follow these steps, you are giving your children the best.

School Daze: PCBs in New York City Schools

By Caroline Newton 

Working in the Enforcement Division of EPA’s New York City office has made me think of environmental issues and public health risks differently than before.  I find it both fascinating and alarming how the environment directly and indirectly impacts the people in the surrounding community. 

One topic that I have paid increasing attention to (and the media has as well) is PCBs in schools. PCBs, or polychlorinated biphenyls, are man-made organic chemicals that were used in hundreds of industrial and commercial applications until their manufacture was banned in 1979. They were commonly mixed into caulk, a material used to seal windows and doors. Although the caulk that we purchase today does not contain PCBs, caulk in buildings such as schools that were built before 1979 may still have caulk that contains PCBs.  Over time, caulk can deteriorate and the PCBs become airborne, and people can inhale them. PCBs have been demonstrated to cause cancer, as well as a variety of other adverse health effects on the immune system, reproductive system, nervous system, and endocrine system.

A source of PCBs in schools that was less widely known until recently is lighting fixtures. Certain older lighting fixtures contain ballasts that have PCBs in them.  When these ballasts age, they can crack or even spark and catch fire, causing PCBs to enter the air that students breathe. 

Over 700 of NYC’s public schools were found to have older, PCB-containing lighting fixtures. Inspections performed by EPA about a year ago in approximately seven NYC school buildings showed that many of these ballasts had cracked and were leaking PCBs.  As a result, NYC is taking on an energy improvement program that will incorporate the removal of all PCB-containing lights from its schools. The New York City School Construction Authority posts this type of information on its website

Schools throughout the country may have similar problems. In November 2011, EPA Region 2 sent letters to Superintendents in NY and NJ informing them of this problem and encouraging them to take an inventory of the lights in their schools to determine their age and potential for having PCB-containing ballasts. 

If your child or someone you know attends a school that was built before 1979, you may want to speak to the Superintendent or someone at the school about this topic and ask questions. If it was built prior to 1979, have the lighting fixtures been replaced since? Does the school have a protocol for dealing with possible PCB-containing ballasts? You may want to share with them EPA’s guidance on Proper Maintenance, Removal, and Disposal of PCB-Containing Fluorescent Light Ballasts
