Emergency preparedness plan(EPP) is the systematic management of activities that involve a material degree of risk of loss or other damage to the surroundings(people, property and environment), and the boundary of accident recovery plan(ARP). The main purpose of the program is to provide a safety management system to each facility in order to enable to prevent accident and to control accident immediately. The EPP includes not only typical safety-related documentations such as material safety data sheet(MSDS), standard operation procedure(SOP), emergency response plan(ERP). EPP is established basis of the preliminary safety analysis involving risk identification, assessment and prevention plans. The program is also helpful for government or related agencies to control a number of accidents in small-scale companies in the whole country.

The analysis of stable isotope ratios can be utilized effectively to identify the environmental impact of pollutants emitted from various sources. When it is necessary to determine the mechanism of various reactions in the field of air quality, such as ozone and secondary aerosol formation, the isotope ratio analysis can provide more useful information than conventional analytical methods. In particular, the atmospheric effect of biogenic volatile organic compounds (BVOCs) emitted from trees has been drawing keen attention in recent years. In this study, the carbon isotope ratios of resin extracted from Pinus koraiensisleaves, as well as the resinextracted leaves, were analyzed with an isotope ratio mass spectrometer (IR-MS). The delta values of13C of resin extraction (R) and resin-extracted leaves (L) ranged from -30.74 to -28.64 ‰ and from -30.34 to -27.32‰, respectively. The difference of d13C between resin and leaves were 1.45 ~ 1.70 ‰. This study may be contribute to laying the ground for the stable isotope analysis of BVOCs on which few case studies have been reported. In the future, it will be necessary to collect more relevant data and analyze the carbon isotopes of individual BVOCs.

Over the last 10 years, about 200 chemical accidents have occurred. The frequency of chemical leak accidents has particularly increased since the 2012 accident of hydrogen fluoride gas leakage. When a chemical accident happens, the released gas-phase substances are more likely diffused into the air, which subsequently might cause serious damage to the health of local residents and the environment. To make a quick response to such a chemical accident, it is significantly important to promptly analyze the accident-causing substances. In this study, a cross analysis was performed using PTR-TOF-MS and GC-MS to identify accident-inducing substances generated in the reaction process with brominated epoxy resin and acrylic acid. As a result of the two analyses, acrylic acid was not found to induce a chemical accident, whereas aromatic hydrocarbons and 2-bromophenol were both identified as accident-causing substances. Given that rapid analysis is essential for a prompt response to chemical accidents, the cross analysis using two or more techniques may be useful to quickly identify accident-causing substances.
화학사고 신속 대응을 위한 대기 시료 포집방법 비교연구 -염화수소와 불화수소를 중심으로-

Among all chemical accidents that have occurred over the last decade, those related to acid chemicals account for 41%, which indicates that acids are very likely to cause accidents. Once released, acids can move to various media such as air, water and soil, subsequently having effect on the environment. In particular, they spread very quickly when leaked in gaseous phase into the atmosphere. Considering these characteristics, it is very important to make immediate responses to acid leakage. It is also essential to promptly analyze the concentrations of acids in the air to assess their effect on human health and the environment. However, Korea has no official testing methods applicable to inorganic acid leakage, and inevitably relies on foreign testing procedures instead. In this study, research was conducted with hydrogen chloride and hydrogen fluoride, both of which present high accident rates and serious aftereffects. The efficiencies of sampling with impingers and sorbent tubes were compared using IC analysis. Hydrogen chloride and hydrogen fluoride captured by impingers showed their recovery rates as 105% (±20.7%) and 99.4% (±14.1%), respectively. When silica gel tubes were applied, the rates were each 83.0% (±6.1%) and 88.0% (±13.6%). These two sampling methods were found to have recovery rates ranging from 83 to 105%, and their precision was within 20%. This indicates that both methods are adequately applicable to on-site sample capturing. The adsorption approach with sorbent tubes is considered especially useful for chemical accidents that need to be quickly responded to, because it uses a simple set of equipment, helping save much time for preparing and setting on site.

Hexachlorobenzene (HCB) and pentachloorbenzene (PeCB) are banned globally as POPs under the Stockholm Convention. Those are still emitted as a by-product from certain industrial activities such as waste incinerations,metal production etc and are undergone long-range atmospheric transport. It is difficult to identify the sources of those compounds due to the varieties of point sources. Recently, studies on stable isotopes of POPs have been carried out to get more information about the sources. In this study, the carbon isotopes of HCB and PeCB were analyzed using EA-IRMS (elemental analyzer - isotope ratio mass spectrometry) to examine the possibilities of application as a tracer for POPs sources. The carbon isotopic ratios of both HCB and PeCB were obtained through the EA-IRMS. The isotopic ratios of the standards produced from two different manufactures were compared. The δ13C values of HCB ranged from -26.05‰ to -25.28‰, and those of PeCB ranged from -29.20‰ to -29.19‰. The relative standard deviations were less than 0.24% for EA-IRMS analysis of carbon isotopes and the difference between the value of cross-product manufacturing company appeared.
