Abstract

As increasing concerns about potential risks and hazards in children's products, the laws and regulations for heavy metals and phthalate retardants contained in the children's products have been reinforced in many countries. Especially, in Korea, environment and health laws and regulations for children's products was declared in 2009. This study was researched in terms of contents and migration of phthalates and heavy metals in 124 children's products sold in the Korean market. The results for contents of heavy metals showed that 123 products contained different 14 heavy metals depending on kinds of products. As the results of migration by sucking, the heavy metals in the products such as black, plastic dolls, wood toys, and bottom mat for swimming were transferred into extraction solution. Ba, Cu, Zn, and Sn were transferred from most of these products into the extraction solution and Co, Ni and Pb were additionally transferred into several products. As the results of migration through a skin, while Ba, Cu, and Zn were transferred from most products containing the heavy metals, as for accessories, Cr, Ba, Ni, Zn, and Cu were migrated. The results of contents of phthalates presented that 21 products contained DBP, DEHP and DINP. Only 2 products showed the migration of DEHP by sucking. DEHP in most products were transferred and DBP for 2 products and DINP for 7 products were migrated.

어린이용품의 위해성에 대한 관심이 증대됨에 따라 프탈레이트계 가소제와 중금속에 대해 세계적으로 규제가 날로 강화되고 있다. 우리나라에서도 2009년부터 환경보건법에 어린이용품에 대해 건강상에 문제를 일으킬 수 있는 물질에 대한 규제를 법적으로 고시 해 왔다. 본 연구에서는 우리나라에서 유통되는 어린이용품에 대해서 경구 및 경피 노출이 야기될 가능성이 높은 제품들 중 22개 제품군에 대해 총 124개 제품을 선정하여 제품 내 프탈레이트와 중금속의 함유량과 전이량을 조사하였다. 124개 제품 중 123개 제품에서 중금속 14종에 대하여 분석결과 중금속이 함유되어 있는 것으로 확인되었다. 경구 전이량 결과에 따르면 블록류, 플라스틱 인형, 목재완구, 놀이용 바닥매트, 물놀이용품이 전이가 가능하였고 분석 결과 대부분의 제품에서 바륨(Ba), 구리(Cu), 아연(Zn), 주석(Sn)의 인체 전이가 일어날 수 있는 것으로 조사되었고 일부 품목에서 코발트(Co), 니켈(Ni), 납(Pb) 등이 추가적으로 전이가 가능하였다. 경피 전이량 분석 결과 바륨(Ba), 구리(Cu), 아연(Zn)은 악세서리를 제외한 대부분의 제품에서 전이가 가능하였고 악세서리의 경우 크롬(Cr), 바륨(Ba), 니켈(Ni), 아연(Zn), 구리(Cu)가 전이 가능하였다. 프탈레이트 분석 결과, 124개 제품 중 21개 제품이 함유되어 있는 것으로 확인되었다. 함유량 분석 결과 DBP, DEHP, DINP의 검출을 보인 제품을 대상으로 경구 전이량을 조사한 결과, 물놀이용품 2개 제품에서 DEHP 물질의 인체 전이가 일어날 수 있는 것으로 조사되었다. 경피 전이량 분석 결과 대부분의 제품에서 DEHP의 전이가 가능하였고 DBP는 2개, DINP 7개에서 경피 전이가 일어날 수 있는 것으로 조사되었다.
