IIUC, there have only been (few) case studies on this, and this paper reads like a plea for larger studies. But they also think TCE should be banned right away for other reasons: > In many ways, the long-established health risks of TCE dwarf its relationship with PD. TCE causes cancer, increases the risk of miscarriages, contributes to birth defects, and is associated with diseases in nearly every organ system. The chemical is over a century old. We do not fly airplanes from the days of the Wright brothers or drive cars from Henry Ford’s era; engineers have developed safer ones. Chemists can do the same for solvents. Some companies now advertise safer alternatives to TCE [83]. They are needed as the use of TCE continues to rise globally.
