Health status of plant workers exposed to fluorochemicals--a preliminary report.

Higher than normal levels of organic fluorine were found in the blood of workers exposed to fluorochemicals in an industrial environment. No ill health effects attributable to exposure to fluorochemicals were found among these workers. The ambient air in the process operation areas in the plant was found to contain measurable amounts of organic fluorine. Through certain modifications in the process steps and improvements in engineering controls. A substantial reduction in the airborne fluorochemical levels within the plant was achieved.
