Mortality Study of Pesticide Manufacturers/Formulators Documentation of the Velsicol Chemical Company, Marshall, Illinois Plant.
The mortality of pesticide formulators and manufacturers at the Velsicol Chemical Company (SIC-2879) in Marshall, Illinois, was investigated. Employment histories were collected for approximately 2300 workers employed for at least 6 months between 1940 and 1964. Vital status was determined through December, 1976. Worker deaths were compared to the United States general population expected death rates. In general, the employees of the Marshall facility had a lower mortality rate than the general population. The worker death rate from all types of cancer also was below the expected rate, however, stomach, respiratory, and central nervous system cancer deaths were in excess of the expected rates for workers employed for more than 36 months. Increased time of exposure appeared to increase the risk of death. The authors recommend that workers eat outside of the workplace and change clothing at the factory. Air sampling should be conducted regularly at the liquid filling areas to determine the necessity of respiratory protection.
