Analysis of Determination of Urine Arsenic in 563 Cases / 昆明医科大学学报

ABSTRACT

The urine arsenic of 563 workers was determined;an investigation on labor hygien in the workshop and a physical examination of these 563 cases were made.The results indicate that the present suggested value of urine arsenic is rather high in the Yunnan area.In order to raise the reference value of determining urine arsenic in the diagnosis of arsenic poisoning,we suggest that the upper limit of the normal value of urine arsenic be 0.1mg/L and establish an area health standard throughout the country.
