HewJerwy. 1978-1979 Study | 1 tn 1978, prompted by anofosr compauj Informing DuPor.I that elevated organic fluorine levels had been 1 observed In the blood of their workers who had been exposed to cettiin fltrerinoted surfcetints, DuPont ! initialed it study of their Chambers Works workers potentially exposed to DuPont floorotdomer-based iluorosurfoctants- Although the Chambers Works workers did not Handle the specific chemicals 1 manufactured by the other company ond wed a different manufacturing process for the fluorwar&ctants manufactured on site, DuPont performed a study which included measurement id total orgeole fluorine ITOF) levels In die blood of workers and a review of medical files to determine if say advene health effects could to associatedwith potential exposure. O verview Chambers Works employees were identified who had job assignments with potential for exposure, A subset were selected for flood monitoring representative of the larger worker giutgl. These Included employees tn recearch. semi-works, end manufacturing operations. A control group of DuPont office workers in Wilmington, Delaware was also tested. Blood samples were taken daring regulady scheduled > physical exams and analysed for total organic fluorine (TOP). The mulls of the tem were reported td the employees. Results | The other company reported that 0.002 to 03 ppm TOF w o preseal In Ike blood of foe general i | populationtO.Ol to O.Ofi ppm TOF In their plant office workers; 0.13 to 1.18 ppm, TOF In thnir general i j plant workers', and0.09 to 71 ppm In plant worker In fortrfiuorlnated surfactantsproduction area. i DuPont results showed none detected to 0.38 ppm TOF Is the Wilmington office otters control group and none detected to 0.37 ppm TOF In foe Chambers Works workers group. DuPont canelsded foot the Chambets Works employees did not have elevated levelt of TOF In foeir blood as compared to the OttPeoi Wtlnungton office worker enneel group. Hot did foe worker poop show elevatedTOF levels as was reported far workers of foe other company. In addition, o health and morbidity study of foe Worker 1 group who had potential for exposure wot no different than the overall plant control group and did not I suggest hoy adverse health effect attributable in cupusmc to ftuorateiotterdxued chemicals. It Was ranclmtetf that no further employee blnnd monitoring would he continued. ?c.Oo0 n c Buck Page 1 of 2__________________ IWOI/OI 714 Ayiwwmi U [>\`PONfT ruNflD fcNTIAL hrteftdrt oriy fw tiw u w fi t)AN R1VERbAit#i# PATE Anymutl'iarind cpywp- rev#, et dadaguro Hpnidbted s> described in fo ApmM ii, DuPont Confidential Information Worker Monitoring Summary 1999-2000 Study In Fall 1999, DuPont planned letstart-up it new product operation nt (lie DuPont Chambers Work where there was potential employee eepuatre to fliiorinated chemicals.
