Welders at risk for anosmia

Welders working in enclosed, poorly-ventilated spaces might be at risk for anosmia (loss of sense of smell), according to a recent study at the University of Pennsylvania. UP researchers studied 43 professional welders, comparing their scores on a scratch-and-sniff test with the scores of non-welders. Findings showed significantly less olfactory abilities among the welders, but the actual cause of the sensory loss remains unclear. Further research with other non-welder industrial workers is indicated to further hone in on the causes of the problem. Read more at Science Daily
