Absorption of xylene is mainly by
inhalation of vapour but significant skin absorption may
occur. Approximately 95% of the solvent is rapidly
metabolised to methylbenzoic acid, which conjugates with glycine to
form the corresponding methylhippuric acid, which is excreted in
the urine. Urine samples (25 ml) should be collected at the
end of shift.
There is an HSE Biological
Monitoring Guidance Value of 650 mmol methylhippuric acid
/mol creatinine, based on exposure to 50 ppm (8h-TWA) at rest.
