• Description:
  The neurotoxic effects of chronic exposure to elemental mercury (7439976) were investigated in workers in a chloralkali facility. The Wechsler digit span and short term memory (STM) span were used. Tests were given twice, with sessions 3 months apart. Urine samples were taken and 50 percent threshold spans were evaluated as a function of session and urinary mercury content. The Wechsler digit span was not very precise for measuring STM; the variance was high within subjects. There was no significant relationship between Wechsler digit span and urinary mercury concentrations. The 50 percent threshold STM span reduced the within subject variance from 1 to 0.15 digits. The STM span decreased substantially as mercury exposures increased. Decrements in STM span from aging were compared. Exposure to 0.20 milligrams per liter of mercury had the same effect on the 50 percent threshold span as increasing the worker's age from 20 to 44. [Description provided by NIOSH]
