One form of this condition results in a triad of tremors, gingivitis, and erethism. This condition, which is the cause of itai-itai (10[1])disease and Minamata disease, (10[1])is often treated with medical-grade (10[2])Prussian blue, (10[1])succimer, or sodium calcium EDTA in chelation therapy. For 10 points, what condition is caused by prolonged exposure to elements like lead or mercury? ■END■
