A young electrician with a painful gouty arthritis in 2005 became the first case observed of occupational exposure of toxic amounts of molybdenum (1). Molybdenum is an activator of xanthine oxidase, which oxidizes xanthine producing uric acid (2). Too much produced hyperuricemia (1). The electrician can be thankful that his doctors found the cause of the gout because of previous men afflicted with gout by having consumed 10 to 15 mg of molybdenum daily (3;4). Tolerable uptake limits are set at 2 mg (2).
