Studies on kidney function in subjects exposed to organic solvents. I. Excretion of albumin and beta-2-microglobulin in the urine.

The urine of 134 subjects, exposed to different organic solvents, and 48 unexposed subjects has been analysed with reference to albumin and beta-2-microglobulin excretion. The exposed subjects excreted significantly larger quantities of albumin than the unexposed. Those exposed to styrene excreted the largest amounts. No significant difference in beta-microglobulin excretion could be demonstrated between the groups.
