가용성이란 무엇인가? | 니켈, 크롬 등 일부 금속은 가용성화합물(또는 수용성 화합물)과 불용성화합물로 구분하여 노출기준이 설정되어 있다. 여기서 가용성(soluble)이란 수용성(water soluble)과는 구별될 수 있는 것으로 금속 화합물이 체액(body fluids)이나 표적장기(target organ)에서 물을 비롯하여 산이나 알칼리 등에 용해되어 건강영향을 나타낼 수 있는지를 고려한 의미라 할 수 있다(Fairfax & Blotzer, 1994; NOSH, 2016b). 우리나라의 니켈화합물에 대한 노출기준은 가용성화합물(soluble compounds)이 0. | |
노출기준이 설정된 물질은 무엇인가? | 우리나라 작업환경측정대상 금속 가운데 화합물의 용해도 특성을 고려하여 노출기준이 설정된 물질은 니켈, 바륨, 백금, 알루미늄, 은, 크롬, 텅스텐 등이다. 니켈의 경우 금속원소, 가용성화합물, 불용성무기화합물 등으로 구분하여 노출기준이 설정되어 있다. | |
작업환경측정대상 금속의 노출기준이 용해도에 따라 다른 이유는 무엇인가? | 크롬의 경우는 크롬 금속을 비롯하여 크롬2가, 크롬3가, 크롬6가 화합물에 대한 노출기준이 설정되어 있는데 크롬6가 화합물의 경우는 수용성과 불용성이 구분되어 있다. 노출기준이 용해도에 따라 다르게 설정되어 있는 것은 같은 금속의 화합물일지라도 인체에 미치는 영향에 차이가 있기 때문이다. 따라서 이들 금속화합물에 대해서는 용해도를 고려하여 작업환경평가가 이루어져야 한다(Park et al. |
