선진국에서 유해물질을 함유하는 소비자 제품의 위해성 관리를 위해 CONSEXPO등의 다양한소비자 노출평가 모델을 개발하여 소비자 제품에 함유된 유해화학물질의 노출로 인한 위해도를 평가하고 이를 규제 기준의 설정근거로 활용하고 있다. 이에 본 연구에서는 다양한 시나리오에 적용할 수 있는노출평가 모델을 검토하고 대상 제품을 선정하여 적정 모델을 적용하여 위해성 평가 단계에 따라 위해성 평가를 하여 제품 별 위해성 평가 기법을 마련하고자 하였다. 작성된 노출 시나리오를 바탕으로 노출계수를 선정한 뒤 CONSEXPO 노출평가 모델을 기반으로 하여 알고리즘을 작성 한 결과 프탈레이트류의 경우 일부 장판에서 전이량이 검출되었으나 함량과 전이량의 상관관계를 살펴본 결과 r-square 0.0065으로 상관관계가 거의 없는 것으로 나타나, 이 결과를 기준으로 함량 기준값을 산출하는 것은 무리가 있다고 사료되며 현행제품기준을 유지하는 것이 무방할 것으로 판단된다. 휘발성유기화합물 또한 인체에유해하지 않은 것으로 나타났으므로 현행 기준을 준수 할 경우 큰 무리가 없을 것으로 것을 판단, 새로운 기준을 제시 하지 않았다. 중금속의 경우 전이량이 검출되지 않았으므로 위해성 평가는 수행하지 않았다. 따라서 경피노출로 인한 인체의 유해가능성은 매우 적을 것으로 판단할 수 있다.
In advanced countries, a variety of consumer exposure assessment models including CONSEXPO,are developed to manage risks of consumer products containing hazardous materials. The models are used toassess the risks of exposure to hazardous chemicals in consumer products, which serves as a foundation forregulation standards. In this study, exposure assessment models applicable for various scenarios were reviewedand a proper model was applied for the selected products and risk assessment was conducted at each stageto establish a risk assessment procedure for different types of products. Based on the exposure scenario, exposurefactor was selected and according to the algorithm produced based on CONSEXPO exposure model, somelevel of phthalates were detected from some types of PVC flooring. However, a correlation between phthalatecontent and migration rate showed r-square 0.0065, little correlation, which is inadequate for estimating standardvalue. For this reason, it seems valid that the current standard be in place. Additionally, any new standard wasnot suggested as VOCs were not found harmful to human health, allowing the existing standard to becontinuously applied. No migration rate was found for heavy metals and risk assessment was not performedaccordingly. In this aspect, it is presumed that hazards to health through dermal exposure would be very little.
