C W 1999 data similar to 1979 & Wilmington Controls. 1979 CW workers were from "fluorochemical/ fluorosurfactant operations from Jackson & Tech Labs 6 small and full scale manufacturing operations. A review of the medical records of 200 potentially exposed employees did not suggest any adverse health effects attributable to exposure to fluorochemicals. Group o f 55 sampled was representative of 199 cohort." Reported as organic fluorine. 1981, July 'August. CW workers from Polymer Products 6mployee & u s in flj3klfeMMPt[C-8) which had moved to CW.
