  • Objectives: Paints contain various types of metal substances. However, our review of MSDS (Material Safety Data Sheets) for paints found that their components were often kept secret or exact content information was otherwise not provided. We analyzed the metal elements in various inorganic pigment-based paints available in South Korea in this study and checked whether they contain hazardous metal substances as defined by the Occupational Safety and Health Acts. We investigated issues of health hazard classification related to the metal elements. The study is intended to contribute to strengthening the management of hazardous substances by suggesting improvements to MSDS. Methods: We randomly selected 19 samples that were predicted to contain hazardous inorganic pigments after reviewing MSDS among paints currently in use. The samples were analyzed using XRF (X-ray Fluorescence spectrometry), ICP_OES (Inductively Coupled Plasma-Optical Emission Spectroscopy) and SP-ICP-MS (Single Particle-ICP-Mass Spectroscopy). Results: The most common elements in the samples were Al (aluminum), Fe (iron), Ti (titanium), Ca (calcium), and Si (silica). One sample contained more lead than allowed by the limits. There were ten samples that could potentially contain nanoforms, seven samples that contained titanium dioxide, and six samples that contained complex inorganic color pigments (CICPs). Conclusions: Inorganic pigments in paints should be evaluated for hazards separately from other metallic compounds and reflected in the MSDS because they have different characteristics than other metallic compounds. These include particle size, crystal structure, and complex substances. The results of this study can be helpful for determining whether a paint contains sufficient hazardous metal compounds to affect its classification, and it can be a guideline for improving MSDS through comparative review and rationalization with the manufacturer's MSDS. This would make it possible to contribute to the management of chemical substances in the workplace through the proper MSDS disclosure of paints.

  • Potential chemical hazards encountered in painting operation of four shipyards and a ship-repair shop were investigated through the material safety data sheets (MSDS). Material safety data sheets (MSDS) for 307 paints, 50 thinners and 34 binders were collected and reviewed. It was shown that various organic solvents such as aromatic hydrocarbons, aliphatic hydrocarbons, ketones, alcohols, glycols, glycol ether acetates and esters were contained in painting materials. Of these solvents, xylene was found in the largest number of painting materials. sixty percent of the thinners contained xylene in the contents of 20-100%. Other most frequently found solvents were 1-methoxypropanol, 1-methoxypropyl acetate, n-butanol, methyl isobutyl ketone, toluene, isopropanol, and n-butyl acetate, etc. Glycol ethers such as 2-methoxyethanol (2-ME), 2-methoxyethyl acetate (2-MEA), 2-ethoxyethanol (2-EE), 2-ethoxyethyl acetate (2-EEA) and 2-butoxyethanol (2-BA) were regarded as having the potential to cause adverse reproductive effects, embryotoxic effect and hematotoxic effects, and were found in some epoxy panting materials. Coal tar pitch was included in some paints(13%) where polynuclear aromatic hydrocarbons (PAHs) could be contaminated. Inorganic pigments such as lead chromate and zinc potassium chromate were found in some paints (8%). The epoxy resin based paints, which may contain isocyanates such as toluene diisocyanates and hexamethylene diisocyanates causing potential sensitization and asthma to upper respiratory organ, were mostly used in the shipyards. The constituents in the MSDS were significantly different from the results analyzed using gas chromatography/mass detector: minor constituents or impurities were omitted in many MSDS. In conclusion, xylene was the most frequent organic solvent in painting materials, and glycol ethers, including 2-ME, 2-MEA, 2-EE, 2-EEA and 2-BA, were found some products. Also, painting workers may be exposed to PAHs, lead, chromate, isocyanates, organic tin and other various chemicals. The compositions of chemicals in painting materials were variable significantly, and the hazards were changed. These facts should be considered in environmental monitoring and control of the hazards.

  • In order to overcome the urban heat island effect, highly functional paint is attracting attention as a promising means by shielding heat on the structure (building) surface. When a paint was prepared containing nano-sized silica particles, the heat-insulating performance was relatively higher than that of paints with other sizes. In addition, developed paints showed enhanced properties such as chemical resistance and abrasion resistance test because of the presence of nano-sized silica included in functional paint.

  • 교통사고로 인해 피해자 의류 또는 사고관련 차량에 부착된 페인트는 법과학적으로 중요한 증거물이다. 의류에 부착된 페인트는 용의차량을 추적하고 교통사고의 피해자임을 입증할 수 있는 단서가 되며, 피해차량과 용의차량에 상호 전이되어 부착된 페인트는 페인트의 동일성 비교로써 사고의 진실을 밝히고 사고 상황을 재구성하는데 중요한 역할을 한다. 부착된 페인트는 보통 미량의 시료이고 특히 단색인 흰색, 노란색, 적색, 청색, 검정색인 경우 페인트 동일성 비교는 입체현미경으로 색상과 안료에 함유된 알루미늄, 펄, 마이카 등의 입자 형상에 대한 상호 비교가 곤란하므로 이에 대한 분석법이 요구되었다. 따라서 본 연구의 목적은 단색의 차량 페인트에서 색상을 구현하는 basecoat 층에 대해 micro-FT-IR과 micro-XRF를 이용하여 안료의 바인더 수지와 무기안료의 구성원소를 확인하여 법과학적 측면에서 페인트 동일성 비교를 하고자 하였다. FT-IR 분석은 시료를 전처리 없이 Reflectance와 ATR 2가지 방법을 병용했으며 Reflectance 스펙트럼은 $4000{\sim}2000cm^{-1}$ 영역에서 aromatics과 aliphatic, acrylonitrile 등의 피크 정보를 얻었고 ATR 스펙트럼은 $2000{\sim}650cm^{-1}$ 영역에서 carbonyl, isocyanate, carbamate 등의 피크 및 피크의 패턴 비교로 안료의 바인더 수지를 비교하는데 이용하였다. 또한 XRF 분광법은 미량 페인트의 무기안료에 함유된 구성원소를 확인하여 적외선 흡수스펙트럼으로 동일성 비교가 곤란한 시료에 대해 판별 가능하게 하였다.

  • Although shipbuilding workers were exposed to a variety of genotoxic compounds including polycyclic aromatic hydrocarbons (PAHs), limited number of studies were conducted to evaluate the biomarkers related to PAH exposure in painting workers in shipbuilding industry. One hundred and thirty three workers including 73 employees using coal tar paints were recruited from a shipbuilding company located in South Korea. Urinary 1-hydroxypyrene glucuronide (1-OHPG), as internal dose of PAH exposure, were measured by synchronous fluorescence spectroscopy after immunoaffinity purification using monoclonal antibody 8E11. Glutathione S-transferase (GST)M1 and GSTT1 genotypes were assessed by multiplex PCR. Information on demographic characteristics, smoking gabit, diet, job title, use of personal protective equipments were collected by self-administered questionnaire. Urinary 1-OHPG were higher in workers using coal tar paints than in workers using general paints, however, the difference was not statistically significant (p=0.20, Mann-Whitney U test). Urinary 1-OHPG levels in smokers were higher than in non-smokers (p<0.05 by Mann-Whitney U test) and there was a significant increase in urinary 1-OHPG levels with the numbers of cigarettes consumed per day (Spearman's correlation coefficient = 0.28, p=0.02). Genetic polymorphisms of GSTM1 and GSTT1 did not influence the level of 1-OHPG in study subjects. Multiple regression analysis show that smoking is the only significant predictor for lon-transformed 1-OHPG (overall model R2=0.1). These results suggest that workers using coal tar paints were exposed to significant amount of PAHs and individual difference in xenobiotic metabolism might affect the levels of internal dose of PAHs.

  • The night visibility of pavement is being considered as a global issue in the field of traffic safety. Although the spreading glass beads on the lane paints has been mainly used to secure night-visibility by utilizing the effect of retroreflection, obvious shortcoming of this method is that retroflection does not occur in the range where the headlights do not reach the glass beads. The use of functional paints including phosphorescent constituents could be a solution for overcoming fore-mentioned problem. SrAl2O4 based chemicals have not only good phosphorescent property, but also are chemically stable compared to existing ZnS based materials. However, this chemicals also need the improvement due to slightly reduced luminous effect in time. Herein, we developed novel paints showing enhanced phosphorescent properties by putting rare earth elements such as Eu, Dy and Y into SrAl2O4. These prepared phosphorescent pigments have displayed improved properties in terms of durability and long afterglow. For instance, the property of afterglow has been persisted after 5 hours with luminace of 20.6 mcd/m2.
