In this study, 38 residents of the Jeonnam areas in Korea were assessed for their level of exposure to VOCs. The aim was to understand the difference in levels of indoor, outdoor, and personal exposure to VOCs (benzene, toluene, ethylbenzene) and a health effect assessment was conducted to determine whether there was any fatal cause from carcinogenic or non-carcinogenic elements from case and control group. Personal exposure to benzene showed a higher distribution than indoor and outdoor concentrations, and it was found that the average concentration of the case group was higher than that of the control group in all indoor, outdoor, and personal exposures. With regard to benzene, in the CTE, RME, and Monte-Carlo analysis, all subjects in the case group were seen to exceed the lifetime cancer risk of 10−6 defined by the US EPA and in the RME analysis the control group subjects were also seen to exceed the lifetime cancer risk of 10−6 defined by the US EPA. In the case of toluene, ethylbenzene on the CTE, RME, and Monte-Carlo analysis, the non-carcinogenic standard of 1 was not exceeded.
하이브리드 감압 열펌프 건조기의 효과를 파악하기 위하여 건조된 굴 제품을 8주간 저장하면서 일반 성분의 변화와 글리코겐 함량의 변화 등을 조사하였다. 일반세균의 변화는 18~19×103 CFU/g으로 기존제품의 27~30×103 CFU/g 보다 안전하였다. 주요 지방산의 함유량은 건조기에서 건조한 시료의 DHA 및 EPA 함량은 L1-1, L1-3 및 R2-2에서 각각 17.87% 및 14.80%, 17.46% 및 14.38%, 17.89% 및 14.99%이었고, 반면 CD-1은 각각 15.41% 및 13.20%로 약간의 차이를 보였다. 각 시료의 유리아미노산 함량에는 큰 차이를 보이지 않아 1325.2~1360.4 mg/100 g으로 나타났다. 그리고 선도를 나타내는 K 값에서는 하이브리드 건조기에서 건조한 시료가 저장기간 동안 매우 우수한 신선도를 나타낸 반면, 시판 굴의 시료에서는 34.0~42.1%로 나타났다.
