Abstract
This study investigated prevalence of color vision loss different from children's residence. The study subjects are 3 to 6 grade's children of elementary school in four areas. The blood lead and urinary mercury were analysed using Atomic Absorption Spectroscopy. All of participations' blood lead and urine mercury concentration were below suggested level of concern such as criteria by CDC and ATSDR. Color vision was assessed by the Lanthony D-15 desaturated panel. Color vision loss was quantitatively established by the Color Confusion Index (CCI) and qualitatively classified by type of acquired dyschromatopsia according to Verriest's classification. The prevalence of color vision loss and CCI value for children in industrial area was significantly higher than other areas(p<0.05). However blood lead and urinary mercury concentration level was not correlated to the color vision loss. Therefore we believed that other environmental neurotoxic substance except metal had an effects on color vision loss for children in industrial area.
본 연구에서는 지역에 따른 어린이들의 색각이상 유병율을 보고자 했다. 연구대상자는 4개 지역의 3-6 학년 초등학생들을 대상으로 하였다. 혈중 납과 요중 수은은 원자흡광분석기로 측정을 하였으며, 모든 연구대상자들은 CDC와 ATSDR 권고기준 이하였다. 색각검사는 Lanthony D-15 desaturated panel test를 이용하였으며, 정량적 평가와 정성적 평가를 동시에 시행하였다. 연구결과 공단지역 어린이들은 다른 지역에 비해 높은 색혼돈지수와 유병율을 보였다. 환경오염노출과 관련해서는 혈중 납과 요중 수은과의 연관성은 찾을 수 없었다. 따라서 본 연구결과 공단지역 어린이들의 색각이상에는 다른 영향요인이 작용했을 것으로 본다.
