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.

Organic solvents are known toxic effects like vertigo, behavioral obstacle, distracting, and peripheral neuropathy in neuron areas. However, there have been few studies how neurotoxic solvents-exposed workers are affected by the cognitive load of preceding working memory tasks. Therefore, we used fMRI as to measure the neural correlates of working memory impairment in occupational workers who had from chronic exposure to organic solvent. Twenty-nine solvent-exposed workers were included in this study. Each participant concluded the verbal N-back tasks (1- and 2-back) during the fMRI acquisition. Within-group analyses showed fronto-parietal networks were active in each condition. Direct comparisons between 1- and 2-back showed higher activation during the 2-back than 1-back. We found that increased activation of these regions at lower task demand is associated with increased cost of implementing.

Our study investigated the association between solvent exposure and acquired color vision loss using the Lanthony D-15 desaturated panel in petrochemical industry. Since neurotoxic effects associated with chronic solvent exposure, subjects with more than 6 months of exposure were included. Exposure assesment was estimated mean, maximum and cumulative 8hr TWA from individual 8-hour sampling. Exposure status were classified into two groups, occupationally exposed group to solvent and a non-exposed group. The results showed that CCI was positively related for age. According to the results of qualitative analysis, there was no significant difference in the prevalence of specific Type of dyschromatopsia the two examined group. However, the prevalence showed a higher proportion of dyschromatopsia to solvent exposure. It was affect with acquired dyschromatopsia(Type II, III and Complex) in exposed worker group(5.9%,7.86%,14.99%, respectively) than in the nonexposed group(6.16%,7.55%,13.71%, respectively). After each variable was adjusted for age, alcohol and tobacco consumption, a relationship between acquired dyschromatopsia and exposure showed an increase in the Odds ratio as compared to the nonexposed group at only left. The results showed that acquired dyschromatopsia was positively related to age (p<0.001). The results showed that solvent exposure, although not significant, could cause the acquired dyschromatopsia and visual system can serve important information on early neurotoxic effects in generally. Therefore, we need to concerns about eye health in workers.

고령 근로자의 작업환경 실태와 건강검진 자료를 분석하여 그들의 건강한 생활과 삶의 질을 향상시킬 수 있는 정책의 기초자료를 마련하고자 시도되었다. 대상자는 부산, 경남지역에 소재하는 41개 사업장에서 유해인자에 노출되어 작업하는 공정에 있는 50세 이상 근로자 112명(남성 91명, 여성 21명)을 대상으로 소음, 분진, 유기용제, 중금속, 작업형태 및 작업강도 등을 측정, 분석하였으며, 건강검진 자료는 일반건강진단표를 이용하여 다음과 같은 결과를 얻었다. 1. 대상자의 평균연령은 54.9(남성 55세, 여성 54.7세) 세였으며, 평균근무기간은 8.7년이 였으며, 조사대상 사업장중 71.5%가 50인 이하의 근로자를 고용하고 있는 사업장이 였다. 2. 소음에 폭로 대상자 중 31.3%가 90dB(A)인 노출기준치을 초과하였으며, 그 외의 분진, 유기용제, 중금속 등의 노출기준치를 초과한 대상자는 없었다. 3. 조사대상자 중 9%는 청력이 비정상이였으며, 78.6%의 대상자는 경작업과 중등작업을 하였으며, 52.7%는 전신을 이용하여 작업하는 형태였다.

최근 경제적 수준의 향상과 더불어 도시인의 생활 양식에도 큰 변화가 초래되어 1일 실내 생활 활동시간이 증대되고 있다. 따라서 실내 생활의 비중이 많은 현대인에게는 실외 대기 오염 물질에 대한 노출 기회보다 실내 공기 오염물질에 대한 노출 기회가 많아 실내 오염의 중요도가 높다(Bloemen and B)urn, 1993). VOCs의 실내 발생원은 주로 건축자재 혹은 가구 및 담배연기 둥이며, 페인트나 유기용제 둥을 사용하는 생활용품에서도 다량 배출되어 인체에 직접적인 노출의 원인이 되고 있다.(중략)
