유기용제는 상온, 상압 하에서 휘발성이 있는 액체로서 다른 성분을 녹이는 성질이 있으며, 사용목적에 따라 단일 용제가 사용되나 대부분은 2종이상의 혼합용제 형태로 도장, 인쇄, 접착, 세정작업등 제조업뿐만 아니라 건설, 운수, 서비스업에 이르기까지 광범위하게 사용됨으로써 이를 사용하는 근로자에게 건강장애를 일으키기 쉽다. 사업장에서 사용되는 용제의 77%가 혼합용제이고 특히 도료에서의 혼합유기용제 사용비율은 93%, 신나 85%, 잉크 73%, 접착제 67%이며 세정제에는 단일 용제가 많이 사용되는 것으로 보고 되고있다. 유기용제 사용에 의한 건강장애를 예방하기 위해서는 유기용제의 사용실태 파악과 정확한 작업환경측정 및 평가를 통한 작업환경관리가 매우 중요하다고 생각 할 수 있다.

현재 투과증발은 유기용제/물의 탈수, 유기/유기분리, 이성질체의 분리, 폐수중의 유기물의 분리등에 응용이 되고 있으며, 그 중에서 유기용제/물 혼합물중 에서 물을 선택적으로 분리하여 유기용제를 농축하여 건조시키는 공정이 가장 많은 발전이 이루어졌다. 일반적으로 유기용제는 그 용도의 전개에 있어서 물을 함유하고 있을 경우 제 기능을 발휘하지 못하기 때문에 포함하고 있는 물의 농도를 가능한 최소화하여야 한다. 본 고에서는 탈수용 투과증발막의 개발에 관련하여 막재질의 선택과 탈수용으로 연구되어온 고분자막 소재에 대하여 알아보고, 실제적으로 고분자막이 유기용제의 탈수에 어떻게 응용이 되는지를 알아보겠다.

급속한 경제 성장에 따른 산업구조의 고도화 및 다양화로 인하여 유기용제는 많은 사업장에서 널리 사용되는 물질의 하나로 종류도 매우 다양해져 400여종 이상이 되며/sup 1)/, 사용량도 매년 10%이상 증가하고 있어 근로자에게 직접 또는 간접적으로 폭로되어 건강에 나쁜 영향을 초래하고 있다. 유기용제에 의한 건강 장해를 예방하기 위해서는 유기용제의 사용 실태파악과 정확한 작업환경측정 및 평가를 통한 작업환경관리가 산업위생학적 견지에서 매우 중요하다고 생각할 수 있다/sup 2)/.(중략)

A comparison was made between workers exposed to organic solvents and those not exposed to them regarding stress perception and psychopathology, using GARS scale and SCL-90-R. The exposed group scored significantly higher than the non-exposed group in stress perception relevant to job-wort changes in relationship, sickness or injury, financial, and overall global area. The exposed group was significantly higher in somatization scale than the non-exposed group. However, there was no significant correlation between duration of exposure and psychopathology. In each of the groups. female workers showed more psychopathology than male ones. Age showed significantly nagative correlation with psychopathology. These results suggest that the exposed group shows higher stress perception and more psychopathology than the non-exposed group. Thus. it is emphasized that health policy makers as well as employers should pay more attention to health. espcially mental health for the workers exposed to organic solvents.

The purpose of this study was to evaluate the effect of organic slovents and noise on hearing loss. We selected organic solvents exposed group of 32 cases, noise exposed group of 31 cases, both noise and solvent exposed group of 31 cases, and control group of 53 cases and studied the relation between exposure level of noise and organic solvents and degree of hearing loss. The results were as follows. The subjects under investigation were exposed to noise and organic solvents under threshold limit values and the amount of urinary hippuric acid excretion were also under biological exposure indices. In case of noise, both noise and organic solvents exposed group and noise exposed group were more exposed than organic solvents exposed group(p<0.05). When urinary hippuric acid excretion were concerned, both noise iud organic solvents exposed group and organic solvents exposed group showed higher values than noise exposed group(p<0.05). In comparison of mean auditory threshold values by frequency, on the air conduction test, both noise and organic solvents exposed group showed significantly higher hearing loss than noise exposed group in 500Hz of right ear, 500 and 2000Hz of left ear(p<0.05). Forty-three cases among 147 subjects were regarded as hearing loss group and average age(42.6years) of hearing loss group was higher than normal groups average age of 38.0 years. Urinary hippuric acid excretions of hearing loss group were significantly higher than normal group(p<0.05). Thirty-eight percent(12cases) of noise exposed group, 40.6 $\%$(13cases) of organic solvents exposed group, 51.6 $\%$(16cases) of both noise and organic solvents exposed group, and 3.8 $\%$(2cases) of unexposed group were regarded as hearing losers. Exposed groups showed higher incidence of hearing loss than unexposed group but there were no significant differences among the exposed groups. The variables showing significant correlation with hearing loss were age and the amount of hippuric acid in urinary excretion. When age were adjusted for the purpose of seeing the effects of hearing losses due to organic solvent, urinary excretion of hippuric acids was the only variable with significant correlation with hearing loss (p<0.05). When odds ratio to hearing loss between control and exposed groups was considered, noise exposed group showed 6.1 times (95 $\%$ CI: 3.3-8.7), organic solvents exposed group showed 7.4 times (95 $\%$ CI: 3.5-14.6) and both noise and organic solvents exposed group showed 17.2 times(95% CI: 5.6-31.8) higher values than unexposed group(p<0.01). Above results suggest that health screening test of hearing loss is also needed in organic solvents exposed workers.

현재 많은 산업현장에서 휘발성 유기용제를 사용하고 있다. 국내 환경부에서 규제대상 VOC로 고시하고 있는 물질(환경부고시, '98. 7.1.)은 레이드 증기압, 광화학반응성, 물질사용량, 발암성 등 유해성을 감안하여 31개를 선정하여 규제하고 있으며 앞으로 규제대상 물질을 점차로 확대하여 나갈 계획으로 있다. 이에 한정된 자원의 고갈을 방지하고 환경의 보존을 위해 공정상에서 유기용제의 사용을 대체하는 것이 가장 이상적이나, 현재의 여건으로는 맡은 시간이 소요되므로 효율적인 휘발성 유기용제 처리공정 개발이 시급한 실정이다.

Organic solvent를 원료로 한 액상 세척제는 가전제품, 컴퓨터용품, 전기기구 세척등의 민수 용품과 산업용 정밀 기계부품과 같은 대상물 세척 등에 사용되고 있다. 그러나 일반 유기용제를 주성분으로 한 유기용제형 세척제의 경우 장기 오염물질에 따른 세척력 저하, 공정상 VOC(Volatile Organic Compound)가 과도 발생할 뿐만 아니라 비생분해성, 높은 증기압, 화재 및 폭발 위험성, 냄새 성분 발생 등 안전 및 보건상 치명적인 결함이 있다.(중략)

We investigated the occurrence of color vision loss in 70 organic solvent mixtures exposed workers and in 47 controls. Color Vision was assessed with a color arrangement test designed to identify the defective color sense, the Han Double 15-Hue Test. The results of the test were no significant difference between exposed workers and controls in the proportion of subjects who committed one or two errors. Quantitative analysis, using color confusion index(CCI), showed no signicant difference between exposed workers and controls. A significant linear correlation was present between age and CCI in both exposed workers (CCI=0.0056age + 0.94; r=0.23; p<0.05) and controls(CCI=0.0066age + 0.86; r=0.33; p<0.05). Qualitative analysis of the patterns on the hue circle showed that the prevalence of acquired dyschromatopsia was 21% in both and no significant difference. Multiple regression analyses showed that age was significantly related to color vision loss. These results did not provide evidence of a relationship between organic solvents exposure and incidence of color vision loss. In field studies for monitor the people at risk of the acquired color vision loss involving low-dose organic solvents exposed workers, both quantitative and qualitative information should be considered.
