No, the aerosol was zinc cadmium sulfide. It wasn’t testing of biological and chemical weapons, it was testing of a simulant to model how those weapons would disperse through a city.
The official story was that the aerosols were "biological simulants." If the official story could have gotten away with zinc cadmium sulfide, it would have.
Page 69:
"The St. Louis study may have involved far more than biological “simulants”, per the official military talking point. There is indication of a secret study conducted in tandem to the “official” military-sponsored St. Louis aerosol study. The second study, which for some reason warrants even more secrecy than its parallel study, appears to have been connected to a new type of deadly nuclear weapon, one of many being developed by the coalition, to be tested on unsuspecting residents of St. Louis"
Admittedly, I couldn't find a precise source used by the dissertation stating that "biological simulants" other zinc cadmium sulfide were sprayed specifically on St. Louis. One of the references isn't available online. It might also have been a source that was overlooked in the references.
Anyway, it's 2024 now, and more information has come to light. Martino-Taylor's 2011 belief has been confirmed. US News reported [1] on the situation as recently as September 2023, quoting a member of the House of Representatives acknowledging that it really did happen:
"Democratic U.S. Rep. Cori Bush of St. Louis said in a statement that she and her staff "are currently looking into alternative pathways that the federal government can take to ensure those impacted by the spraying of radioactive compounds and biochemicals in Pruitt-Igoe are also addressed.”"
I’m talking specifically about the claim that there was a secret study tandem to the zinc cadmium sulfide one that was testing a new type of nuclear weapon on the population. The dissertation doesn’t refer to any of its sources or references for this claim.
