| Abstract: | The problems of refining metallic mercury as they relate to the health of the worker are described. The reliability of several methods for assessing the work environment is shown and a relationship between high mercury environment, increased body load of mercury (as evidenced by urinary excretion), and symptoms of mercurialism in exposed mill workers is demonstrated. Because of the poor reliability of urine mercury levels in determining impending or early mercury poisoning, several biochemical analyses on blood of mill workers were performed. Support is given to the current threshold limit value (TLV) for mercury. However, the data show that this level contains no more than a safety factor of 2. |
