a limited study in a glassware factory ( as2o3 exposure ) involving the measurement of total airborne arsenic , the determination of urinary arsenic , and the evaluation of hand and mouth contamination by arsenic before and after the workshift suggests that the high urinary arsenic levels ( 300 microgram/g creatinine ) are likely to be more related to an increased oral intake from contaminated hands than to an increased absorption from the lungs .
