Title Health effects of occupational exposure to acrylamide using hemoglobin adducts as biomarkers of internal dose
Bibliographic information Aug. 2001, Vol.27, No.4, p.219-226. Illus. 23 ref.
Abstract A total of 210 workers at a tunnel construction site exposed for about two months to a chemical-grouting agent containing acrylamide and N-methylolacrylamide underwent a health examination. Blood samples were drawn for the analysis of haemoglobin (Hb) adducts of acrylamide. 50 workers claiming recently-developed or deteriorating symptoms of the peripheral nervous system (PNS) were referred to a neurophysiological examination. Workers with Hb-adduct levels exceeding 0.3nmol/g globin attended follow-up examinations 6, 12, and 18 months after exposure cessation. 47 workers had Hb-adduct levels within the normal background range (0.02-0.07nmol/g globin), while the remaining 163 had increased levels up to 17.7nmol/g globin. Clear-cut dose-response associations were found between the Hb-adduct levels and PNS symptoms. However, the PNS symptoms were generally mild and reversible in almost all cases.
