Paying special attention to the recent problems of industrial heavy metal poisoning of workers along with rapid industrialization of the whole country, a retrospective causal study on heavy metal exposure, such as, lead, cadmium, copper, zinc, and so on was performed. To compare the analysed results of 1.06 urine samples taken from letter-press printing industry workers (lead workers) in Seoul, a total of 46 urine samples from normal adults was also analysed as a control study. The summarized results were as,follows;
1. The average concentrations of .heavy metals of above mentioned urine of lead workers were significantly higher ":than ;those of -control group ranging 1.4-3.9 times (p<0.01) ; :lead: 3.9 times ;_(90.-3f7&2mll)
