After learning that the Army conducted secret chemical testing in her impoverished St. Louis neighborhood at the height of the Cold War, she wonders if her own government is to blame.
In the mid-1950s, and again a decade later, the Army used motorized blowers atop a low-income housing high-rise, at schools and from the backs of station wagons to send a potentially dangerous compound into the already-hazy air in predominantly black areas of St. Louis.
Local officials were told at the time that the government was testing a smoke screen that could shield St. Louis from aerial observation in case the Russians attacked.
But in 1994, the government said the tests were part of a biological weapons program and St. Louis was chosen because it bore some resemblance to Russian cities that the U.S. might attack. The material being sprayed was zinc cadmium sulfide, a fine fluorescent powder.
Now, new research is raising greater concern about the implications of those tests. St. Louis Community College-Meramec sociology professor Lisa Martino-Taylor's research has raised the possibility that the Army performed radiation testing by mixing radioactive particles with the zinc cadmium sulfide, though she concedes there is no direct proof.
But her report, released late last month, was troubling enough that both U.S. senators from Missouri wrote to Army Secretary John McHugh demanding answers.
