| 설명 | 통계용어로 표본 평균치 분포의 표준편차를 나타내는 것이다. 표본 평균치가 모집단의 평균치 주위에 산재하는 것은 표본 크기와 모집단의 표준편차(σ)에 의해 지배된다. 표준오차(SD)는 이론적으로 σ/√N으로 나타낸다. |

| 영문 | environmental pollution | 한글 | 환경오염 |
|---|---|---|---|
| 설명 | 인간활동에 의해 발생하는 대기-수질-토양 오염 및 소음-진동 등으로 자연환경이나 생활환경을 손상시키는 현상. 공장-사업장 등에 생산활동, 자동차-기차-항공기-선박 등의 수송활동, 냉난방-취사-여가선용 등 일상생활을 포함한 각종 인간 활동에 의해 유발되는 인위적인 대기오염- 수질오염-토양오염-소음-진동-지반침하-악취 등의 발생으로 자연환경이나 생활환경을 손상시키고 궁극적으로는 사람의 생활 및 건강에 유해한 영향을 미치는 현상을 말한다. 이는 특히, 산업혁명 이후에 두드러지게 나타났으며, 인간활동이 주어진 환경공간의 고유한 자정능력을 초과할 경우 발생한다. 지금도 공해라고 표현하는 사람이 있으나 현재는 환경오염이라는 용어가 표준용어가 되었다. 공해라는 낱말의 어원은 영국의 공중불법방해에서 비롯되었다고 한다. 그러나 공해라는 말은 주로 일본에서 쓰이고 있을 뿐 국제적으로도 환경오염이라고 한다. |
