Abstract

For the management of mercury-containing products, the products were selected to do material flow analysis in preference of not having selected in previous studies. Domestically mercury have been added to pigment for prevention of bacterial growth. So, in this study paint containing pigment was selected as a target. 71 samples of paint products collected in 2014 and data of 38 samples of wastes (dust, sludge, paint) analyzed in 2010 were used in material flow analysis. The result shows that mercury was 0~0.25 mg/kg in products and 0.23~0.69 mg/kg in the wastes. In the material flow analysis, the amount of flow in the process of distribution was 10.06 kg/year, but the amount of flow in disposal like a landfill, incineration and recycling was much than distribution as 25.27 kg/year. It was caused by different sampling period between collecting products and data of wastes. Therefore, It could be possible to be affected from regulation by RoHS like decreasing usage of mercury in paint products or eradicated in the industry. Mercury contents in current paint products are very low to affect discharging to the environment.

안료 페인트 생산 업체 7개를 방문하여 제품 21개(안료 17개, 페인트 4개)를 시료채취 하였으며, 대형 온라인 판매상을 통하여 50개 제품을 구매하였다. 총 71개 제품에 대하여 EPA 7473 방법으로 수은 함량분석을 하였고, 물질흐름 분석을 위한 폐기물 내 수은함량은 타 연구(2010)의 안료 페인트 제조 업체에서 발생되는 분진 슬러지 폐페인트 38건의 수은 함량 자료를 사용하였다. 물질흐름분석은 제품 또는 특정 화학물질을 대상으로 하는 Micro 수준의 물질흐름 추적방식을 이용하여 흐름도를 작성하였다. 수은분석 결과, 71개 제품에서 0~0.25 mg-Hg/kg, 38개 폐기물에서 0.23~0.69 mg-Hg/kg으로 나타났다. 물질흐름을 살펴보면 유통단계의 수은흐름량이 연간 10.06 kg인데 반해 폐기되는 수은의 양은 25.27 kg으로 유통량 보다 폐기량이 더 높게 나타났다. 이는 제품과 폐기물의 시료채취 시기가 달라 발생된 현상으로 제품은 2014년도 제품, 폐기물은 2010년 분석된 자료를 사용하여 RoHS 등과 같은 규제의 영향으로 수은 함유 페인트 제품이 감소됨에 따른 것으로 판단된다. 현재 생산되는 제품 중 수은의 농도는 매우 낮고 페인트에 의한 수은의 유출은 미미한 것으로 판단된다.
