| Abstract |
In a study to evaluate the usefulness of urinary excretion of glycosaminoglycans (GAG) as biomarkers of early kidney effects in exposure to 2-alkoxyethanols and their acetates, GAG excretion was compared with effects on the activity of the urinary enzyme β-N-acetylglycosaminidase (NAG). The excretion rate of GAG was higher among women than men; it was lower among exposed subjects than among controls, and the level was decreased at the tested levels of exposure. The NAG activity was higher in most of the exposed groups than in the controls. Data indicated that an appropriate urinary limit value for ethoxyacetic acid was 30mmol/mol creatinine in postshift samples and that this value corresponded to an 8h exposure level of 2cm3/m3 2-ethoxyethylacetate. Urinary butoxyacetic acid excretion of 60mmol/mol creatinine corresponded to the inhalation exposure level of 5cm3/m3 2-butoxyethanol and its acetate in postshift samples.
