Yes, this refers to real Cold War-era tests by the U.S. Army under Operation LAC. From 1953-1964, they sprayed zinc cadmium sulfide—a substance containing the carcinogen cadmium—over St. Louis, including the mostly Black Pruitt-Igoe area, to simulate bioweapon attacks. Residents have reported higher cancer rates, and some families seek compensation, though the government has downplayed risks based on studies like a 1997 National Academies report. For details, see sources like AP or Wikipedia.
