Objectives: This study was performed in order to devise a procedure for supplementing the Special Management Materials in the Occupational Safety and Health Act and recommend candidate materials. The results are expected to be used as fundamental data for classification and criteria necessary to manage Special Management Materials in workplaces. Also, they are expected to be used as a basis for selecting target materials to nominate as additional Special Management Material. Methods: We investigated the selection standards for candidates and review ranges of data sources to nominate Special Management Materials. The substances classified as GHS(Globally Harmonized System of classification and labeling of chemicals) category 1A(known to have carcinogenic potential and reproductive toxicity for humans) or 1B(presumed to have carcinogenic potential and reproductive toxicity for humans) carcinogens and reproductive toxicants among the Controlled Hazardous Substances of the Regulation on Occupational Safety and Health Standards and substances with OELs(Occupational Exposure Limits) were inspected as the candidates for Special Management Materials. Conclusions: A seven-step procedure for selecting candidates to designate as Special Management Materials was suggested, including the setting of target chemicals for evaluation, classification of CMR(Carcinogens, Mutagens or Reproductive toxicants) by GHS classification and criteria, suggestion and selection of the candidates, and more. This study recommends 58 chemicals as qualified candidates to supplement the Special Management Materials.

It is believed that cell and/or tissue toxicity is resulted from alterations in expression of many genes in response to environmental stresses or toxicants. New technology, such as DNA microarray analysis, can measure the expression of thousands of genes at a time providing the potential to accelerate discovery of toxicant pathways and specific gene targets.(omitted)

본 연구를 통해 환경 유해성을 평가하기 위한 동물세포를 개발했고 이를 이용한 모니터링 방법 연구와 다양한 독성 물질에 대한 반응성을 확인했다. 개발된 독성 모니터링 동물세포(KFC-A10)는 각 독성 물질에 따라 빛의 발현 양이 증가하는 성향을 가지므로 이번 실험에서 사용된 MMC, BPA, ${\gamma}-ray$에 농도 의존적으로 빛의 양이 증가함을 관찰할 수 있었다. 특히 BPA의 경우는 환경호르몬으로 알려진 바 그 estrogenic 효과를 관찰할 수 있었다.

Microalgae are sensitive indicators of environmental changes, and hence they are widely used in environmental risk assessments and for the development of discharge guidelines. Here we evaluated the toxicity of metals and endocrine-disrupting chemicals (EDCs) to the marine green microalga, Tetraselmis suecica. The toxicants investigated included the metals, Cu, Ni, and Pb; and the EDCs, bisphenol A (BPA), endosulfan (ES), and polychlorinated biphenyl (PCB). The endpoints were variations in cell counts and chlorophyll a levels. T. suecica displayed a varied pattern of sensitivity to the toxicants. Based on the 72-h median effective concentration ($EC_{50}$), ES (0.045 mg/L) was most toxic to T. suecica, followed by PCB (3.96 mg/L) and Pb (9.62 mg/L). Interestingly, T. suecica was relatively tolerant to Cu (43.03 mg/L). The 72-h $EC_{50}$ values of Ni and BPA were approximately 16 mg/L. Our data suggest that this species may be relatively tolerant to most of the chemicals within their permissible limits in the environment.

Objectives: This study was performed to provide workplaces with political guidelines that apply international CMRs (Carcinogens, Mutagens, Reproductive toxins) information to Public Notice of TLVs (Threshold Limit Values). We analyzed information supply status about CMRs of international agencies and compared substances for which TLVs are set in KMoEL (Ministry of Employment and Labor in Korea). Methods: We referred to the reliable literature about classification criteria of CMRs corresponding to UN GHS (Globally Harmonized System of classification and Labeling of chemicals) and Public Notice No. 2009-68 'Standard for Classification, Labeling of Chemical Substance and Material Safety Data Sheet' in KMoEL. The classification system of CMRs in professional organizations (IARC, NTP, ACGIH, EU ECHA, KMoEL, etc.) was investigated through the internet and literature. Conclusions: 191 chemical substances among total 650 substances with TLVs are classified as carcinogens. Also, 43 substances classified as mutagens, and 44 as reproductive toxicants. These results suggest that the information of CMRs in Public Notice of TLV will be reorganized to 191 carcinogens, 43 mutagens, and 44 reproductive toxicants.

Objective: The purpose of this study was to investigate the hazards of cosmetic ingredients in Korea. Methods: An Excel database of cosmetic ingredients was developed on a website(Korea Cosmetic Ingredient Dictionary) and used for a hazard assessment based on Tox-free, a database containing toxic information such as on carcinogens, mutagens or reproductive toxicants(CMRs) and endocrine disrupting chemicals(EDCs), as well as other regulated chemicals in Korea. Results: A total of 16,605 chemicals were registered with the cosmetic ingredient dictionary and 308 of them were identified as either CMRs or EDCs. CMRs included formaldehyde and nickel gluconate, and EDCs included parabens, benzophenon, styrene, and toluene. Reproductive toxicants such as xylene, zinc chloride, toluene, and formaldehyde were regulated by the Occupational Safety and Health Act and the Act on the Registration and Evaluation, etc. of Chemical Substances(the Chemical Control Act). Conclusions: Regulations on cosmetics components should be strengthened, and the right to know about cosmetics containing hazardous chemicals should be guaranteed.
