Automated method for determination of mercury in urine.

I describe a sensitive, specific, automated method for determination of mercury in urine by the "flameless atomic absorption" technique. One can analyze 20 samples per hour, with less than 0.5-ml samples of urine. The detection limit is 0.01 mumol/liter (2mug/liter) and the mean coefficient of variation 12%. The procedure is being used to monitor mercury excretion by workers exposed to mercury.
