  The aim of this research was to investigate the correlation between chromium (VI) concentration in the breathing zone of workers and total chromium in urine specimens as a biomarker of exposure in chromium electroplating workers. In chromium plating, different airborne concentrations of chromium (VI) can be released into the breathing zone of workers. For measurement of chromium (VI) concentration 69 air samples were collected by filtration technique and collected samples were analyzed using NIOSH method 7600. Air sampling from breathing zones was conducted by personal sampling method and further personal exposures to chromium VI was calculated as Time-Weighted Average (TWA) values. For biological monitoring total chromium in urine was measured using WHO method, also this method has been recommended by ATSDR. For this purpose 92 urine samples were collected and analyzed by atomic abso.. Read More»
