The leakage of toxic chemicals impact seriously on human being and environment, therefore during their treatment process, a proper management system is necessary to control their toxic effect. This study was designed to suggest the management regulation that supports business managers and facilities management. There are no extra regulation to control emergency accidents and terrors in chemical facilities. Developed countries like USA operate the management standards to control the toxic chemical and facilities according to their toxicity and processes. In order to solve this problem, we have analysed the advanced nations standard methods of security in chemical plants to study the new security management regulation which helps to prevent the chemical accidents. Especially, in USA, CCPS (Center for Chemical Process Safety), SVA (Security Vulnerability Assessment) and RBPSs (Risk-Based Performance Standards) of DHS (Department of Homeland Security) were invest I gated. On the basis of the results, we have suggested the application methods of the security and safety regulation in Korea.

With a rapid growth of domestic industry in korea, now about 25,000 kinds of chemicals are being distributed, and it has been known that just about 15% of them has toxic substances. Recently, South Koreans have an anxiety about the stability and accidents of chemicals because chemical accidents like Gumi hydrofluoric acid accident have occurred. The U.S. has adopted the systems like EPCRA (Emergency Planning and Community Right-to-Know Act), TRI (Toxic Release Inventory) and TSCA (Toxic Substances Control Act), and is also managing the hazardous chemicals by providing the information about them to its people and site workers. Japan's Ministry of Health, Labor and Welfare also has adopted J-CHECK system and is implementing it to let Japanese people know the information of safety of chemicals about REACH. However, the Korean government has a difficult situation to mediate the different idea with the Korean industry to make lower statute of Pre-legislation registration & evaluation of chemicals that will be implemented and Chemical Material Control Association that is being implemented. Especially city and country areas located in the industrial areas need political improvement focusing on vulnerable area through the check about current situation of hazardous chemicals of jurisdiction and management method, but the information about the management situation of small scale work places is insufficient. Therefore this study set up the urgent management area in Ansan Smart Hub through NFPA code according to the types of accident and dander characteristics of each chemical being used in the companies that have less than 50 workers and deal with chemicals located in Ansan Smart Hub in Gyeonggi-do.

최근 독극물로 인한 사고가 빈번하게 발생하여 사회적인 문제가 발생하고 있어 독극물관리를 철저히 해야 할 필요성이 대두되고 있다. 2010년 기준으로 국내에는 약 10만 여종의 독극물이 유통되어 사고 시 중증 중독환자 혹은 대량으로 환자를 발생시킬 수 있고 국제적으로도 NBC에 의한 대량 재해의 심각성이 대두되고 있다. 그래서 생산지에서 부터 관리 할 수 있도록 독극물이 들어 있는 유리병에 13.56MHz 대역의 RFID 시스템을 사용하였고, 인식된 태그 데이터는 IEEE 802.15.4 기반의 통신으로 메인 시스템에 데이터를 전송한다. 전송 된 데이터는 스마트 디바이스를 통하여 독극물의 상태를 실시간으로 모니터링 할 수 있는 시스템을 구현하였다. 그러나 독극물을 관리하는 시스템의 고장은 예측 할 수 없는 결과를 발생시킨다. 그래서 고장의 원인이 되는 오류를 하드웨어 여분을 이용한 방법으로 검출하였고 검출된 오류가 전체 시스템에 영향을 주지 않도록 이중화 시스템을 제시하였다.

화학사고의 발생을 감소시키고, 예방하기 위한 공정안전관리(PSM) 제도는 우리나라의 경우 1996년부터 시행되었다. 그러나 PSM 제출대상인 기존 21종 물질에 대한 규정량과 새로이 추가된 브롬화수소 등의 독성물질의 규정량에 대한 타당성 검토가 미흡하여 많은 문제점이 발생되고 있다. 본 연구에서는 25종의 PSM 제출대상독성물질의 규정량을 국내 외 공정안전관리제도와 관련된 규정량과 비교 검토하였다. 그리고 흡입독성, NFPA 지수 등으로 구성된 독성 유해 위험성 식을 제안하여 고위험, 중위험, 저위험의 3등급으로 독성물질을 분류하고, 규정량의 조정에 반영하였다. 본 연구결과의 규정량 개선안은 유사 공정안전관리제도의 규정량 차이로 인한 사업장의 혼란과 부담 완화 및 합리적 개선에 도움을 줄 것으로 기대된다.

Most of chemical plant are using toxic and dangerous materials, inflammable and poisonous. There are many accidental dangers by escaping of fire, explosive and poisonous materials in case of high temperature and pressure. The accidents lead to taking employer's and local people's life and environmental contamination. Therefore, 27 small-medium chemical plant, which size is 30 ∼ 200 employees out of safety management agent ill the area of A was selected in this study. The problems of safety management and several countermeasures at the chemical plants was indicated through the analyzed data. Prior to this analysis, top managers' concerns, equipment maintenance for the safety management are needed. For the future, calamity prevention countermeasures by industrial disaster analysis are needed and active safety management programs are investigated for the industrial disaster prevention and productivity enhancement at the chemical plant.

Chemical accidents occur by a variety of causes and aspects. Accident preparedness substances (APS) are defined by toxic chemicals highly likely to cause accidents due to their high acute toxicity, explosiveness or likely to cause severe damage where a chemical accident occurs among the chemicals. APS is designated and announced by Presidential Decree. However, chemical accidents occurred for recent 7 years were arisen mainly from non-accident preparedness substances, and only 24 species were included as chemical accident trigger among total 69 APS. In addition, APS were designated in 2014 and the list has not been updated since then although it needs to be amended in several aspects. Accordingly, this study analyzes the necessity of modification of APS management, and presents improved plans.

The agricultural industry is beset by continuing demands to decrease the use of pest control agents which employ toxic modes of action. Although there are real problems of pesticide resistance, and sometimes overuse or redistribution in the environment, much criticism results from a lack of appreciation of how small is the risk involved. Whatever the background reasons, research and development for pesticide alternatives, particularly within Integrated Pest Management systems, is clearly of high priority. Currently available approaches, including use of natural products and molecular biology, are often regarded with naive optimism and require critical appraisal. For the future, methods of pest control based on chemicals with non-toxic modes of action (e.g. pheromones) continue to offer promise but, for widespread use, will require their integration with biological agents and development by means of plant molecular biology.

Objectives: This study was carried out to determine $LD_{50}$ of benzo[a]pyrene to decide the possibility to designate them as toxic substance on the Act on the Registration and Evaluation, etc. of Chemical Substances, and to suggest that they should be managed in what level on the Chemical Control Act. Methods: Based on the result of a preliminary study, 300 mg/kg was set as the middle dose. A highest dose of 2,000 mg/kg and a lowest dose of 50 mg/kg were selected based on the OECD TG 423. Benzo[a]pyrene was orally administered once to female and male SD rats at dose levels of 50, 300, 2,000 mg/kg (body weight). All animals were monitored daily for clinical signs and mortality over 14 days. Also testicular spermatid count, motility and etc. were examined as well. Results: Under the condition of this experiment, $LD_{50}$ of benzo[a]pyrene was assumed to be >2,000 mg/kg. In the lesion according to autopsy, there were no specific symptoms in the control and experimental groups. At 2,000 mg/kg, a decrease in the sperm motility was observed. Benzo[a]pyrene should be designated to be toxic substance as the material assumed to be reproduction-toxicity on the Act on the Registration and Evaluation, etc. of Chemicals. Therefore we should abide by legal procedures determined by Chemicals Control Act in treating it. Conclusion: Considering the significant result that sperm motility in the experimental group was inferior to that in the reference group, we suggest that benzo[a]pyrene be designated as a toxic substance.

Many aquatic ecosystems suffer from anthropogenic disturbances, including the introduction of damaging levels of toxic substances. The effects of disturbances include complex relations with various components involved in the systems, and can include physical, chemical, and hydrological disruption depending of the contaminant. Decision Support Systems (DSSs) are developed to help decision makers to deal with complex management crises, through the systematic structuring and evaluation of decisions, and through providing easy-to-use and integrated tools for information elaboration and display. We reviewed various DSSs developed for toxic substances in aquatic ecosystems, and suggested a conceptual framework which is best suited to the management of such issues within Korea. It may assist stakeholders with their decision making process, and in the achievement of a consensus on water management solutions.
