초록

어떤 금속성분의 과다 또는 과소가 폭력성향에 영향을 미치는 지를 분석하고자 1992년 5월부터 1992년 10월까지 대구교도소에 수감된 사람중 형이 확정된 남자 재소자로서 폭력범죄자(살인, 강도, 강간, 상해, 폭력 행위 등과 같은 폭력범죄로 구형 받은 사람 또는 이와 같은 폭력범죄의 전과가 있는 사람) 111 명과 비폭력 범죄자(사기, 절도, 도로교통법 위반, 간통 등과 같은 범죄로 구형받은 사람이면서 폭력범죄의 전과가 없는 사람) 89명, 총 200명을 대상으로 두발중 독성 중금속인 카드뮴 및 납과 필수금속인 아연, 구리, 철, 마그네슘 및 나트륨 함량을 원자흡광분광광도계 (IL, 551)로 분석하였다. 두발중 카드뮴과 납 함량은 폭력범죄자군에서 각각 $0.56{\pm}0.14ppm,\;11.53{\pm}3.32ppm$으로 비폭력범죄자군의 $0.42{\pm}0.20ppm,\;9.63{\pm}4.31ppm$보다 유의하게 높은 함량을 나타냈으나(각각, p<0.01), 구리 함량은 폭력군이 $9.07{\pm}3.85ppm$으로 비폭력군의 $10.53{\pm}5.82ppm$ 보다 유의하게 낮았다 (p<0.05). 다중지수형 회귀분석 결과 폭력성향과 관련되는 요인으로 카드뮴 함량(odds ratio=98.09)이 높을 수록, 미혼인 경우(odds ratio=0.39), 전과(odds ratio=1.57)가 많을 수록, 거주지역(odds ratio=0.44)이 농촌인 경우에 더 폭력적인 성향을 보이는 것으로 나타났다.

To estimate the factors to the inclination of the criminal violence, the content of trace minerals and toxic metals in the scalp hair were measured during the period from May 1992 to October 1992. One hundred eleven violent and 89 nonviolent criminal inmates of Taegu Correctional Institute were selected. The inmates of violent criminals were imprisoned by murder, robber, rape, injury and violent acts. Those of nonviolent criminals were swindle, larceny, and adultery and had no history of institutional violence. The contents of two toxic metals (cadmium, lead) and five trace minerals (Cu, Fe, Zn, Mg, Na) were determined by an atomic absorption spectrophotometer (IL. 551). The contents of cadmium and lead in hair of violent criminals were significantly higher as $0.56{\pm}0.14ppm,\;11.53{\pm}3.32ppm$, respectively, than $0.42{\pm}0.20ppm,\;9.63{\pm}4.31ppm$ of nonviolent group (p<0.01). But the level of copper was significantly lower than nonviolent group (p<0.05). The factors that had a significant correlation with the inclination of violence in multiple logistic regression analysis were cadmium (odds ratio=98.09), unmarried (odds ratio=0.39), many times of criminal history(odds ratio=1.57) and residence of rural area (odds ratio=0.44). The results suggest that the sub-toxic contents of cadmium and lead in the hair may be of potential effect on behavior, and the mineral analysis may be an important adjunctive diagnostic procedure. Further studies into this problem are necessary.
