Back in 1970, the Board of Aldermen acknowledged that there was a lead epidemic in St. Louis. The question now is how much, if at all, that epidemic has changed in the past 36 years. Host Don Fitz and guests Dr. Nadim Kanafani and Barbara Chicherio discuss the issue in an episode of “Green Time” airing on Double Helix Channel 21 in the City of St. Louis. The program is produced by the Gateway Greens in conjunction with KDHX. For more information call (314) 727-8554 or contact fitzdon@aol.com for airtimes.
