Purpose: Workers with chronic health problems find it difficult to maintain their work because of socioeconomic difficulties. The purpose of this study was to evaluate the relationships between physical, ergonomic, and mental health hazards in the workplace and chronic health problems of Korean workers. Methods: A total of 28,807 wage workers participated in the study and were selected using the Fifth Korean Working Conditions Survey (2017). Multiple logistic regression analysis was used to determine the associations between physical, ergonomic, and mental health hazards and chronic health problems. Results: Of the participants, 1,220 (4.23%) had chronic health problems. Even after adjusting the general characteristics, vibration, noise, high temperature, low temperature, dust, chemical and cigarette smoke, fatigue and painful posture, dragging or pushing or moving of heavy objects, repetitive hand or arm movements, working with a computer or smartphone, use of internet or e-mail, and anxiety situations increased the risk of chronic health problems. Conclusion: The study reaffirms that exposure of physical, ergonomic, and mental health hazards in the workplace significantly increases the risk of chronic health problems.

PHAs와 같은 유해유기화학물질의 환경노출에 따른 건강영향을 파악하기 위해서 요중대사산물의 배설량, 유전적감수성 등의 생체지표분석법을 동시에 측정하여 정확한 노출량을 평가하고자 하였다. 또한 직업적, 비직업적 노출인구에 영향을 미칠 수 있는 흡연, 음주, 식이 등의 생활습관과의 상호관련성도 평가하였다. 그 결과 비교적 소량의 PAHs에 노출되는 일반인구에서 요중 1-OHP 및 2-naphthol의 배설량에 가장 큰 영향을 미치는 인자는 흡연이었으며 요중 1-OHP의 배설량은 음주여부, GSTM1 유전자의 다형성에 의해서도 영향을 받음을 알 수 있었다.

Soil quality standards (SQS) are necessary to protect the human health and soil biota from the exposure to soil pollutants. The current SQS in Korea contain only sixteen substances, and it is scheduled to expand the number of substances. Chemical ranking and scoring (CRS) system is very effective to screen the priority chemicals for the future SQS in terms of their toxicity and exposure potential. In this study, several CRS systems were extensively compared to propose the assessment factors that required for the screening of soil pollutants The CRS systems considered in this study include the CHEMS-1 (Chemical Hazard Evaluation for Management Strategies), SCRAM (Scoring and Ranking Assessment Model), EURAM (European Union Risk Ranking Method), ARET (Accelerated Reduction/Elimination of Toxics), CRSKorea, and other systems. The additional assessment factors of CRS suitable for soil pollutants were suggested. We suggest soil adsorption factor as an appropriate factor of CRS system to consider chemical transport from soil to groundwater. Other factors such as soil emission rate and cases of accident of soil pollutants were included. These results were reflected to screen the priority chemicals in Korea, as a part of the project entitled ‘Setting the Priority of Soil Contaminants'.

Purpose: The purpose of this study is to verify the effectiveness of the Environmental Hazards Exposure Prevention Program for Mothers with Young Child (EHEPP-MYC) and to provide basic data for environmental health projects in the community. Methods: EHEPP-MYC was developed based on the protection motivation theory. A quasi-experimental design was applied to evaluate the effectiveness of the program. The number of study participants was 30 in the experimental group and 31 in the control group. The intervention applied to the experimental group consisted of lectures as the main method, current affairs programs, discussions, booklets, animations, and practical training. The program was held twice a week for a total of 4 sessions of 60 minutes each. The effect of applying the program was measured three times through surveys (before, immediately after, and two weeks after the intervention) and analyzed through repeated measures ANOVA. Results: The EHEPP-MYC had significant effects on preventive behavior, perceived severity, perceived vulnerability, self-efficacy, response efficacy, and response costs at three time points. Conclusion: EHEPP-MYC has been shown to be effective in promoting environmental hazards prevention behaviors among mothers of young child. EHEPP-MYC can be used as baseline data for projects developing programs to prevent exposure to environmental hazards and improve the environmental health of communities.

Superoxide dismutase (SOD) activities were investigated from the portions of shoots and roots in accordance with developmental stage and in response to environmental stress and antioxidants using Rhodiola-seedlings. The rates of SOD activities were revealed highly at the portion of roots and its tip of seedlings in the latter stages rather than the initial stages. SOD activities of seedlings in the initial stages treated with sodium chloride and cadmium as environmental stressors showed the decrease by 15 and 30% with respect to the control, respectively. However, in spite of stressor-treatments, the activities in the roots were increased according to the growth period showing a maximum rate of up to 45%. Also, SOD activities of the seedling treated with ascorbic acid as a antioxidant were increased by 46% of control value, but this was similar to the rate revealed in the presence of stressors. These results suggest that SOD activities in Rhodiola-seedlings may be related with the important defence-system against injurious environments.

The Ministry of Environment(MoE) of Korea has recently established the Environmental Health Act. This Act contains a clause related to implementation of Health Impact Assessment(HIA). So, selecting a landfill which was expected to have an influence on human health among major development projects, this study carried out the human risk assessment due to inhalation exposure to landfill gas emission and attempted to measure the possibility of domestic application of HIA in the future. The process for HIA on landfill site extension focusing on human risk assessment is as follows: The first step is to presume and calculate the amount of landfill gas emissions using LandGEM, The second step is to carry out exposure assessment using K-SCREEN Model which is used for predicting the concentration in a conservative method. The last step is to carry out human risk assessment of carcinogenic and non-carcinogenic substances. It is considered that it is likely to apply a technique for human risk assessment due to inhalation exposure to landfill gas emission performed here more specifically in the case of implementing HIA. In addition, it is also believed that more systematic studies are needed to overcome some weak points and limits found in this study and if these weak points and limits are improved more reliable outcomes will be produced.

Purpose: Although the working environment is measured at the construction site, only a few noise and vibration that are typically exposed for each process are performed without measuring the working environment by segmenting the exposed harmful factors. Therefore, it is intended to find the harmfulness of silicon oxide dust, which is most exposed at construction sites, and the complementary points of improvement measures currently being implemented at construction sites. Method: The status was analyzed using the actual condition survey report issued by the Korea Occupational Health Corporation and the Korea Occupational Health Association and data from the work environment measurement institution, and compared and analyzed with the rules on work environment measurement of the Occupational Safety and Health Act. Result: The harmfulness of silicon oxide dust was identified and improvement measures were derived. Conclusion: It is expected that occupational diseases against silicon dust can be reduced if the harmfulness of silicon oxide dust at construction sites is derived and improvement measures are actively applied at the site.

The delicate histological structure of gill in teleosts can be easily affected by a variety of biological, chemical or physical detrimental agents because it is directly exposed to the surrounding water. The epithelium of secondary lamella is thin to allow efficient gaseous exchange and this also renders it particularly vulnerable to various pathogens. As well as the main respiratory role, the gill has other various important functions such as acid-base balance, osmoregulation or the excretion of nitrogenous waste products. Thus destruction of epithelial integrity such as epithelial necrosis or thickening can render a fish very vulnerable to respiratory, secretory and excretory difficulties. This article was tried to describe in detail the common processes of pathological responses correlated to the normal histological structures of the gill in teleosts.
