Urinary hexahydrophthalic acid (HHP acid) levels were determined in 20 workers occupationally exposed to hexahydrophthalic anhydride (HHPA) air levels of 11-220 micrograms/m3. The levels of HHP acid in urine increased rapidly during exposure and the decreases were also rapid after

Occupational immunologic lung diseases caused by exposures to substances such as hexahydrophthalic anhydride are significant health problems. It would be useful to identify risk factors, other than exposure, for occupational immunologic lung diseases such as occupational asthma. Our objective was

A method for the determination of hexahydrophthalic acid, a metabolite of hexahydrophthalic anhydride, in human urine has been developed. The urine was worked-up by liquid-solid extraction, esterified with boron trifluoride-methanol, and analysed by capillary gas chromatography and selected-ion monitoring. Hexadeuterium-labelled

Six healthy volunteers were exposed to gaseous hexahydrophthalic anhydride (HHPA) concentrations of 10, 40, or 80 micrograms.m-3 (65, 260 or 520 nmol.m-3, respectively) for 8 h. The respiratory uptake of the inhaled HHPA was almost complete. Rapid increases in plasma
