9/11 toxins: gypsum
Gypsum is a mineral used to make wallboard, plaster, and cement. Gypsum boards, popularly called drywalls, were widely used to construct the World Trade Center. When the towers were hit, the drywall was pulverized, throwing gypsum dust into the air.
With such a massive disaster, a large volume of gypsum was present in the air. People present in the exposure zone inhaled high concentrations of gypsum. Studies have since correlated gypsum exposure to lung and breast cancer, as well as other respiratory diseases.
