ST. LOUIS (AP) -- Missouri's senators have asked the U.S. Army for more information about a chemical spraying program that included testing in St. Louis about 50 years ago.
Sens. Claire McCaskill and Roy Blunt made separate written requests Thursday asking the Army to produce more information about the St. Louis testing in the 1950s and 1960s.
The St. Louis Post-Dispatch reports that their requests stem from the recently publicized research of Lisa Martino-Taylor, a sociology professor at St. Louis Community College. Martino-Taylor's research raises questions about the chemical components in the aerosol spraying that often took place in St. Louis neighborhoods with largely African-American populations in the 1950s and `60s.
The National Research Council minimized health concerns about the program in 1997, but recommended additional study.
