Newly disclosed documents have revealed details on how the U.S. military carried out testing of chemicals on major U.S. cities during the 1950s and 1960s. Sociologist Lisa Martino-Taylor of St. Louis Community College says zinc cadmium sulfide was sprayed in several cities without residents’ knowledge. The most densely sprayed area appears to have been a housing complex for low-income people in St. Louis.
Lisa Martino-Taylor: "It was pretty shocking, the level of duplicity and secrecy. Clearly they went to great lengths to deceive people. There’s a lot of evidence that indicates that people in St. Louis in the city, particularly in minority communities, were subjected to military tests that was connected to a larger radiological weapons development and testing project."
