In single toxin models and inside a 20-year time span, 10 out of 29 explored pesticides were related to thyroid disease, remembering a few of the most broadly involved ones for the U.S. These include paraquat dichloride, glyphosate, and oxyfluorfen. Also, the risk of thyroid disease expanded relatively to the total number of pesticides subjects were exposed to 20 years before the finding or the exploration interview. In all models, paraquat dichloride was related to thyroid disease. The review appears in the Journal of Clinical Endocrinology and Metabolism. The creators say this study gives the main proof supporting the speculation
