  • The objectives of this study were to evaluate the air quality surrounding an indoor swimming pool, to estimate the cancer risk based on the airborne exposure to trihalomethanes (THMs), and to examine the ventilation efficiency by Computational Fluid Dynamics (CFD). Chlorine and THMs were measured poolside, and in the staff room and reception area. The indoor swimming pool was modeled using the Airpak program, with ventilation drawings and actual survey data. Temperature, flow and mean age of the air were analyzed. Levels of chlorine poolside, and in the staff room, and reception area were $203\;{\mu}g/m^3$, $5\;{\mu}g/m^3$, and $10\;{\mu}g/m^3$, respectively. Chloroform was the dominant THM in all sampling sites and mean concentrations were $16.30\;{\mu}g/m^3$, $0.51\;{\mu}g/m^3$, and $0.06\;{\mu}g/m^3$ poolside, in the staff room and reception area, respectively. Bromodichloromethane and Dibromochloromethane levels were respectively estimated as $10.3\;{\mu}g/m^3$ and $1.7\;{\mu}g/m^3$ poolside, $1.3\;{\mu}g/m^3$ and $0.1\;{\mu}g/m^3$ in the staff room, and were not detected in the reception area. The cancer risks from inhalation exposure to THMs were estimated between $3.37{\times}10^{-7}$ and $1.84{\times}10^{-5}$. A short circulation phenomenon was observed from the supply air vents to the exhaust air vents located in the ceiling. A high temperature layer was formed within one meter of the ceiling, and a low temperature layer was formed under this layer due to the low velocity and high temperature of the supply air, and the improper locations of the supply air vents and exhaust air vents. The stagnation was evident at the above adult pool and the mean age of the air was 22 minutes. Disinfection by-products in the indoor swimming pool were present in higher concentrations than in the outdoor air. In order to increase the removal of pollutants, adjustment was required of the supply air volume and the supply/exhaust position.

  • The Equator Principles are a set of voluntary environmental and social guidelines for ethical project finance. These principles commit banks and other signatories to not finance projects that fail to meet these guidelines. The principles were conceived in 2002 on an initiative of the International Finance Corporation and launched in 2003. Since then, dozens of major banks have adopted the Principles, and with these banks among them accounting for more than three quarters of all project loan market volume the Principles have become the de facto standard for all banks and investors on how to deal with potential social and environmental effects of projects to be financed. While regarding the Principles an important initiative, NGOs have criticised the Principles for not producing real changes in financing activities and for allowing projects to go through that should have been screened out by the Principles, such as the Sakhalin-II oil and gas project in Russia. In early 2006, a process of revision of the principles was begun. The Equator Principles state that endorsing banks will only provide loans directly to projects under the following circumstances: - The risk of the project is categorized in accordance with internal guidelines based upon the environmental and social screening criteria of the International Finance Corporation (IFC). - For all medium or high risk projects (Category A and B projects), sponsors complete an Environmental Assessment, the preparation of which must meet certain requirements and satisfactorily address key environmental and social issues. - The Environmental Assessment report addresses baseline environmental and social conditions, requirements under host country laws and regulations, applicable international treaties and agreements, sustainable development and use of renewable natural resources, protection of human health, cultural properties, and biodiversity, including endangered species and sensitive ecosystems, use of dangerous substances, major hazards, occupational health and safety, fire prevention and life safety, socio-economic impacts, land acquisition and land use, involuntary resettlement, impacts on indigenous peoples and communities, cumulative impacts of existing projects, the proposed project, and anticipated future projects, participation of affected parties in the design, review and implementation of the project, consideration of feasible environmentally and socially preferable alternatives, efficient production, delivery and use of energy, pollution prevention and waste minimization, pollution controls (liquid effluents and air emissions) and solid and chemical waste management. - Based on the Environmental Assessment, Equator banks then make agreements with their clients on how they mitigate, monitor and manage those risks through an 'Environmental Management Plan'. Compliance with the plan is required in the covenant. If the borrower doesn't comply with the agreed terms, the bank will take corrective action, which if unsuccessful, could ultimately result in the bank canceling the loan and demanding immediate repayment. - For risky projects, the borrower consults with stakeholders (NGO's and project affected groups) and provides them with information on the risks of the project. - If necessary, an expert is consulted. The Principles only apply to projects over 50 million US dollars, which, according to the Equator Principles website, represent 97% of the total market. In early 2006, the financial institutions behind the Principles launched stakeholder consultations and negotiations aimed at revising the principles. The draft revised principles were met with criticism from NGO stakeholders, who in a joint position paper argued that the draft fails by ignoring the most serious critiques of the principles: a lack of consistent and rigorous implementation.

  • Objectives: This study was conducted to investigate the actual condition of the farm work environment and personal protective equipment as part of the effort to improve livestock work for the safety and health of poultry farmers and provide basic data for establishing plans to improve and develop personal protective equipment. Methods: For this purpose, a questionnaire survey on general information about stables, the poultry work environment, accidents, the wearing of work clothes and personal protective equipment, and the level of awareness related to personal protective equipment was conducted among 148 poultry farmers. Results: As a result, it was found that poultry workplace environment was exposed to such risks as fine dusts; organic dusts; poisonous gases; odorous substances; chicken excrement; contact with chickens, bacteria or viruses; and accidents related to machine operation. Thirteen percent of respondents suffered severe respiratory diseases, and the most frequently injured sites due to accidents were the hands (25.7%), knees (23.8%), arms (17.3%), and head (10.9%). The most frequent type of accident was collisions between the body and obstacles or machinery during movement (36.4%), followed by erroneous machine operation such as feeders and electric shocks (8.5%). Regarding the wearing of work clothes and personal protective equipment, 51.7% of the respondents wore worn-out clothing or everyday clothes, whereas only 32.0% wore work clothes. The percentage of farmers who wore proper protective equipment for the work environment during poultry work was 48.4%. The most frequently used type of protective equipment was boots (38.9%), followed by mask (36.7%), gloves (36.3%), appropriate work clothes (22.6%), quarantine clothes (17.6%), helmets (13.4%), and goggles (12.6%). The rate of wearing goggles was low because they were considered inconvenient and lowered work efficiency. Furthermore, they purchased everyday products available on the market for their personal protective equipment which were not appropriate for maintaining safety in an actual harmful environment and its consequent risks. As a result of the survey of the awareness level related to personal protective equipment, their levels of awareness of accidents and attitude proved to be average or higher, but the practice of wearing protective equipment and the level of knowledge and management of personal protective equipment were lower. Conclusion: This survey found that the wearing status of personal protective equipment among poultry farmers was insufficient even though they were exposed to risks. Most respondents were aware of the necessity of wearing personal protective equipment and of the potential for accidents, but they did not wear proper protective equipment. Their wearing rate was low due to a lack of knowledge about protective equipment, as well as the inconvenience of wearing it. Therefore there is a need to improve and develop specialized personal protective equipment for respiration, hands, and eyes, as well as work clothes that can protect farmers from major harmful matter that is generated in the poultry workplace. Based on the results of this investigation, we will conduct further studies on the required performance and design directions of personal protective equipment while collecting more objective data through field-oriented assessments.

  • Recently, there has been prevailing of the combined utilization (CU) with herbs and prescribed drugs in medical therapies in the world. But the information about frequency, efficacy and safety of this CU has not well known in Korea, yet. This study aimed to identify the status of CU by Koreans, and to inquire which side effects of CU represent to those people. A self-completed questionnaire survey was performed through each health examination center in twenty general hospitals and one oriental hospital. Of the initial 2,100 health examinees, 1,851 were participated in this survey, resulting in a response rate of 88.1%. The proportion of CD was 26.3%. The most commonly mentioned reason of CD was 'to promote general health and well-being' (17l persons, 35.5%). The main route of taking CD was self-purchase at drugstore or at herbs market, followed by the prescription of (oriental)physicians. 33.0% (151 persons) of those who took the CD rated it as effective. 93 respondents (19.8%) were experienced several adverse effects including nausea, fatigue, and dizziness. The growing simultaneous use of herbal products and pharmaceutical drugs by Korean consumers may be continuously increased the risk of herb-drug interactions. The medical professionals should be provided with comprehensive and up-to-date information about potential benefits and risks of herbs and prescribed drugs. In the future studies it may be recommended to deal common cold, health promotion, indigestion, headache, and hypertension for the effect and safety of the CD by well-organized prospective study design.

  • 펩타이드형 독소인 마이크로시스틴(microcystins, MCs)과 노둘라린(nodularin, NOD)은 남조류라고도 알려진 시아노박테리아에 의해 생성되는 2차 대사산물로, 독소에 오염된 물, 토양 및 비료를 사용함으로써 농산물 내에 축적되고 이를 사람이 섭취함으로써 건강상 위해가 발생할 수 있다. 최근 MCs과 NOD의 농산물 내 오염에 대한 관심이 대두되며 국내외에서 여러 분석법을 기반으로 농산물 내 오염 수준을 조사하고 있다. 하지만 아직까지 수행된 연구가 많지 않으며, 특히 펩타이드형 독소 중 MCs의 분석 연구에 치중되어 있거나 오염 취약 지역에서 재배한 농산물이 주로 오염도 조사에 사용되는 등 연구에 한계가 있으므로 MCs과 NOD의 관리를 위해서는 보다 많은 체계적인 연구가 필요할 것으로 생각된다. 본 연구에서는 체계적인 모니터링 및 안전관리의 기반을 마련하기 위해 MCs 및 NOD의 이화학적 특성, 독성, 분석법, 오염사례 및 관리현황에 대해 기술하였다.

  • 트라이애슬론은 수영, 사이클, 달리기로 구성된 스포츠로 단일종목의 스포츠에 참가할 때 보다 잠재적인 의학적 위험요인을 더 많이 포함하고 있다. 과사용은 스트레스의 증가와 뼈, 관절, 근육, 건 또는 신경의 손상을 일으키며, 지금까지 트라이애슬론 훈련과 경기 중에 발생될 수 있는 과사용 부상은 목통증, 요통, 근육과 건 부상, 인대부상, 만성적인 통증 등이며, 대부분의 과사용 부상은 달리기 훈련시 가장 많이 발생된다. 또한 트라이애슬론 참가자들은 다양한 자연환경과 경기거리에서 완주해야 하는 만큼 부상 이외의 의학적 문제에 직면할 수 있으며, 현재까지 트라이애슬론과 관련하여 보고되고 있는 의학적 위험요인들은 저체온증, 저나트륨혈증, 일사병, 자외선에 과도한 노출, 면역억압, 심리적인 탈진현상, 용혈증 등을 포함하고 있다. ID 경기 중에 발생 할 수 있는 의학적 문제들 가운데 가장 빈번하게 발생하는 증상은 탈진과 탈수현상이며, 그 다음으로 나타나는 문제점들은 저나트륨혈증, 열부상, 저혈압, 화상과 물집, 근육경련 등이다. 그러나 SD와 OD 경기 중에는 달리기 속도가 빠르고 더 높은 강도에서 경기가 진행되기 때문에 일사병의 발생 위험이 더 높고, 경기 시간이 짧은 관계로 저나트륨혈증은 발생하지 않는다. 본 연구는 트라이애슬론 훈련과 경기 중에 발생 될 수 있는 과사용 부상과 의학적 위험 요인에 대한 연구문헌들을 고찰하여 스포츠 활동에 직접 참여하는 엘리트 선수 및 동호인 그리고 스포츠 현장에서 선수들을 지도하는 코치와 대회를 주최하는 관계자들에게 트라이애슬론과 관련된 과사용 부상과 의학적 위험요인에 대한 기초자료를 제공하여 이러한 위험요인들을 미연에 예방하거나 감소시키는데 도움을 줄 수 있는 기초자료를 제시하고자 한다.

  • This study assessed the safety of raw oysters Crassostrea gigas for consumption during processing in a processing plant. Bacterial contamination (e.g., viable cell counts, coliform groups, Escherichia. coli and pathogenic bacteria) and chemical contamination (e.g., heavy metals and shellfish toxins) were measured on raw oysters, a processing equipment, employees and work areas. No total mercury, lead, paralytic shellfish poison, diarrheic shellfish poison or norovirus was detected in any post-harvested oyster samples. However, the cadmium level ranged from 0.1-0.2 mg/kg. The viable cell count, E. coli and coliform group levels in post-harvested oysters ranged from 4.00-4.54 log CFU/g, ND-210 MPN/100 g and 110-410 MPN/100 g, respectively. The viable contaminating cell counts on employees, equipment and work areas were in the range of $0.90-3.46log\;CFU/100cm^2$. Airborne bacteria in the work areas ranged from 0.60 to 1.81 log CFU/plate/15 min. Thus, no significant health risks were detected in the processing plant.

  • Objectives: This study was conducted in order to ascertain the important factors for SMEs in managing the risks of chemicals and to suggest a government role in strengthening the responsibility of small and medium enterprises(SMEs) as employers. Methods: About 100 enterprises were surveyed in Incheon. A questionnaire for employers and walk-through surveys by occupational hygienists were performed at each enterprise. Results: The results showed that most employers thought chemicals were not hazardous but chemical management was needed. When employers determine how to manage chemicals, they rely heavily on personal experience and rather less on information from the government or experts. However, if employers think the chemicals are hazardous, they do more to manage the chemicals. Conclusions: When employers think chemicals are hazardous, risk assessment would be an effective tool to control chemical hazards in SMEs. Employers' position on chemical hazards is very important. Since the government is the initiator, it is the government who develops messages for SMEs, such as "Chemicals are hazardous and management can reduce the risk of chemicals." Governmental messages can play an invaluable role in strengthening the responsibility of SME employers to manage chemical hazards.

  • This review examined the current administrative policies and guidelines for management of reclaimed soils after remediation processes and proposed practical strategies to improve the potential value of the remediated soil as a resource. Three management practices are proposed to facilitate more efficient recycling of remediated soil; obligatory use, quality certification, and tracking of the remediated soils. If properly implemented in utilization of remediated soil, these strategies could contribute to enhancing public safety by assuring soil quality. Such administrative tools, for both suppliers and demanders, are expected to mitigate potential risks associated with the transactions of remediated soil. To enhance the quality assurance process, a soil quality certification combined with the soil health assessment index was proposed. The systematic integration of the suggested practices with soil health assessment can allow to produce optimal results, encompassing affordability, efficiency, and accessibility, which helps establishing more robust 'Remediated Soil Recycling Management System (RSRMS)'. Subsequent researches should be conducted to develop more effective policies that incorporate soil health assessment tools. The proposed management practices for remediated soil, coupled with soil health assessment, can be a pioneering effort to achieve such goals. By fostering an environmentally friendly policies, the sustainable utilization of remediated soil can be attained. Overall, the proposed strategies can provide a sound framework for responsible and sustainable soil management practices.
