휘발성 유기용제 취급 사업장의 위해성평가 및 위해저감 방안 수립 연구

초록

Although several studies have reported the detrimental effects of volatile organic solvents, workers of solvent ink manufacturers who are involved in producing them have been producing them in the absence of specific management or regulation due to a lack of cost-effectiveness and risk analysis. With the application of the system of the Chemical management systems, this study selected a total of 5 types of chemicals such as PMAc, CH, BGAc, DMDG and GBL that should be managed. The amount of the emission of air pollutants contained in the selected chemicals. In addition, DNEL of each raw material was calculated with the use of its NOAEL values. Thus, the degree of detrimental effects on humans were evaluated. The result was that the concentration of the emission of BGAc in humans was found to be possibility of the effects of chronic inhalation toxicity. The replacement of a hand pump in the manufacturing process and a canopy hood with a lateral aspiration one were proposed as the essential methods for improving the safety for the reduction.
