Secret Government Experiment to Simulate a Chemical Attack in St. Louis Exposed
The US Army now admits they sprayed a chemical that contained cadmium, a known carcinogen, on a St. Louis neighborhood to simulate a biological attack. There was no warning and no consent. A neighborhood of more than 10,000 people was sprayed in the 1950s and 1960s. Residents say that the chemicals were sprayed from nozzles on the back of flat-bed trucks and from the tops of buildings; authorities claimed the people doing the spraying were maintenance workers. More than 30 tests were conducted across the US and Canada using zinc cadmium sulfide.
