혈중 납, 수은, 카드뮴 농도와 노출관련 인자

국문 초록 (Abstract)

본 연구는 혈중 납, 수은, 카드뮴 농도와 노출 관련 인자와의 관련성을 파악하고자 하였다. 연구 대상자는 국민건강 영양조사 2009년과 2010년도 40세 이상 90세 미만의 총 2,042명을 대상으로 하였다. 성별에 따른 혈중 납, 수은, 카드뮴 농도 와 노출 관련인자와의 관련성과 성별 차이를 분석하였고, 납, 수은, 카드뮴 노출 관련 인자의 혈중 농도를 비교하였다. 분석 결과, 연령별 차이는 남성은 수은에서만 나타났고, 여성은 납과 카드뮴에서 나타났다(p<.01). 남성은 체질량지수와 허리둘레 별 혈중 수은 농도의 유의한 차이를 보였다(p<.05). 고밀도지단백콜레스테롤은 남성의 납에서 이상지질혈증 판정치가 정상 보다 높게 나타났고, 저밀도지단백콜레스테롤은 여성의 납에서 이상지질혈증 판정치가 정상보다 높게 나타났다(p<.05). 또 한 흡연자가 비흡연자보다 남성의 납과 카드뮴의 혈중 농도가 높게 나타났고(p<.05), 여성은 카드뮴에서만 동일한 결과를 보였다. 음주여부에서도 남성의 음주자가 비음주자보다 혈중 납 농도가 높게 나타났다(p<.05). 가구소득별 수은과 카드뮴의 혈중 농도는 유의한 차이를 나타냈다(p<.05). 혈중 중금속 농도와 노출관련인자와의 관련성은 연령, 흡연 및 음주, 비만 및 이상지질혈증, 소득수준에서 유의성을 보였다.

This study examined the relationships between the blood heavy metal (Pb, Hg and Cd) concentration and exposure-related factors. The subjects were 2,042 (male: 953, female: 1,089) who were recruited through a National Health and Nutrition Examination Survey. Differences in the concentrations of mercury were observed in males, whereas females showed differences in lead and cadmium. Analyses of the blood concentrations according to body mass index and waist circumference showed significantly higher concentrations of mercury. In males, high-density lipoprotein cholesterol of dyslipidemia was higher than normal in the blood lead concentration. In females, low-density lipoprotein cholesterol of dyslipidemia was higher than normal in the blood lead concentration. The blood lead and cadmium concentrations of male smokers was higher than non-smokers, and cadmium showed the same results in females. The blood lead levels were higher in male alcohol consumers than non-drinkers. The blood concentrations of mercury and cadmium showed significant differences according to household income. Blood concentrations of heavy metals were closely related to exposure-related factors, and age, smoking, drinking alcohols, obesity, hyperlipidemia, and household income were found to be relevant.
