Exposures to thallium-sulfate (10031591) and other pesticides were investigated on October 19, 1983 at the Agricultural Commissioners Office (SIC-0721) in Paso Robles, California. The evaluation was requested by an employee representative on behalf of 24 workers, 5 of whom had symptoms possibly related to thallium exposure. Earlier sampling results obtained by California/OSHA were reviewed along with the medical records of the five symptomatic workers. Other workers completed health questionnaires and were given medical examinations. Office floor and attic dust samples contained 26 to 131 parts per million (ppm) thallium and 205 to 2380ppm zinc- phosphide (1314847). Eleven workers reported symptoms of parasthesias, six reported hair loss, and five reported mood or personality changes since working at the office. One worker was identified with a 2 year history of alopecia and neurologic disorders consistent with thallium poisoning. This worker also had axonal polyneuropathy. Seven other workers had neurologic disorders indicative of potential overexposure to pesticides. The authors conclude that a health hazard due to thallium exposure exists at this office. They recommend further medical evaluation of employees with abnormal neurological findings.
