  • Semi volatile organic compounds (SVOCs) are used as plasticizers in building materials, interior materials, furniture, consumer electronics. etc. In the home, these SVOCs mix together with house dust. There is thus concern over the health effects of SVOCS in the home, there is a risk that they ini1uence childhood asthma and allergies. It is difficult to measure SVOCs emission rates from building materials or household appliances utilizing the usual test chamber methods, because the boiling points of SVOCs are higher and they are apt to adhere to the surface of the test chamber used. In this study, we introduce FLEC chamber method, passive sampler method and micro chamber method, which are used in Germany and Japan in order to measure SVOCs emission rates. Characteristic, merits and demerits of test methods are also considered.

  • Some types of semi-Volatile organic compounds (SVOC) that are emitted from plastics used in building materials and household appliances have associated health risks, even at low concentrations. In this study, micro chamber method for measuring SVOC is introduced and SVOC such as di (2-ethylhexyl) phthalate and butylated hydroxyltoluene emitted a flooring material were measured using a micro chamber method. Airflow characteristics in a micro test chamber deeply depended on air exchange rate. From the evaluation using an index of air change efficiency, such as the air age and the coefficient of air change performance, a fixed air exchange rate of $1.5\;h^{-1}$ in the micro chamber is desirable.

  • A gas chromatography-mass spectrometric (GC-MS) method was developed for determining 25 semivolatile organic compounds in water. A 1.0 L water sample was placed in a separatory funnel and saturated with NaCl, and the solution was extracted two times with 40 mL of methylene chloride. Under the established condition, the linear quantification range was 0.02-800 ng/L and the relative standard deviation was less than 15%. The method was used to analyze 16 surface water samples collected from various regions in Gum-River. The samples revealed SVOC concentrations in the range of 0.02-96.8 ng/L. Maximum concentrations of VOCs detected were not exceeded the EPA or Germany guidelines in any of the samples. The developed method may be valuable for monitoring SVOCs in water.

  • 최근 국제적으로는 2005년 대기배출허용기준 강화와 총량규제 도입추진, 대기 배출부과금 제도의 강화 움직임, 대기환경규제지역의 규제지역 확대에 따른 굴뚝자동측정기 부착의무화, VOCs(휘발성유기화합물) 물질 배출원 관리가 강화되는등 환경적 이슈가 점점 높아지고 있는 추세이다. 또 외부적으로 기후변화협약에 따른 온실가스 규제와 스톡홀름협약에 따른 POPs물질(잔류성유기오염물질)규제가 예상되며 이에 따라 국내 환경부에서도 05년까지 오염물질 배출농도 강화와 POPs 물질 inventory 구축작업과 소각로 이외의 다이옥신 배출원에 대한 다이옥신규제 대상시설이 확대될 전망이다.

  • Since the early 1980s, the building is dramatically higher increases. Therefore, the shortage of parking spaces as a social problem has been pointed out. The parking lot utilization of underground space is increasing by like this problem solving countermeasure. However, Most of the organic material is used for construction in the parking lot on the floor. The existing parking zone flooring occupancy surface finishing is harmful gases and environmental hormones cause of the worker. The study on the safety of the worker consider using environment-friendly?high-liquidity ceramic resin mortar materials to evaluate the characteristics and physical properties.
