| 영문 | lead poisoning, saturinism | 한글 | 납중독 |
|---|---|---|---|
| 설명 | 용해성 납을 흡입하거나 삼킴으로써 유발되는 직업병. 급성과 만성이 있으며 대량으로 흡수하여 급성 위장염 증상을 나타내는 급성 중독은 오히려 드물고, 극소량(1일 1mg 이하)의 납을 장기간 지속적으로 섭취함으로써 생기는 만성이 더 심각하다. 납제련업-활판인쇄업-도장업-납유리제조업-축전지제조업 등 납 또는 납을 함유한 물질을 다루는 사람, 또 과거에는 연백을 사용한 분에 의한 화장독이 여성에게 나타나 문제가 되었으나, 오늘날에는 가솔린에 혼합된 안티녹제인 사에틸납으로 인한 중독이 주목되고 있다. 사에틸납 중독의 증상은 여러 가지인데, 빈혈이나 떨리는 증상이 비교적 초기에 나타나고 납선(잇몸에 납이 침착하여 청회백색으로 착색된다)이나 발작적 복통이 특징이다. 일반적으로 납의 증기나 가루가 기도를 통해 체내로 들어가는 경우가 도료-안료에 들어 있는 납이 피부나 소화관을 통해 침투하는 증례보다 증상이 심하다. |

|---|---|---|---|
| 설명 | 지능은 정상이지만 듣기, 말하기, 읽기, 쓰기, 추리 또는 계산능력에 심각한 문제가 나타나는 여러 장애들을 일컫는 용어. 이로 인해 학업성적 및 자신감 저하, 대인관계에서도 사교 능력이 미숙하여 일상생활의 모든 면에서 문제가 나타난다. 성인기 사회적응력에도 영향을 미칠 수 있으며, 행동장애, 주의력결핍, 과잉운동장애, 우울장애 등과 동반되어 나타날 수 있다. 그 유병률은 낮게는 1.7%, 높게는 30% 정도로 추정하고 있지만 학동기 아동의 약 3~9%가 이 장애를 갖고 있는 것으로 알려져 있다. 기초학습기능검사를 통하여 진단한다. 학습의 기회나 교육적인 자극이 부족한 경우, 집중력 부족, 우울증-불안 등 정서적 문제, 신경학적 이상에 의한 경우 등이 원인일 수 있다. 학습과 관련이 있는 뇌기능과 연관된 특정영역에 결함이 있거나 발육지연 또는 장애가 있는 경우도 원인이 된다. 또한 부모가 조기에 자녀의 능력과 적성을 잘 알지 못하는 경우에도 많이 생긴다. |
