  • In order to conduct the environmental assessment of long range transboundary air pollutants over East Asia, the moving pathways of air pollutants are of great importance, which are depending upon the meteorological weather patterns. Therefore regional scale modeling study requires the identified geopotential height distribution patterns to deal with behaviors of long range transport air pollutants for the effective long term atmospheric environmental assessment. In this study the synoptic meteorological classification using cluster analysis technique over Northeast Asia, and its previous applications of the regional scale air pollutant modeling studies were reviewed and summarized in detail. Other synoptic meteorological characteristics over Korean peninsula are also discussed.

  • The National Institute of Environmental Research (3rd KONEHs) conducted a survey of 280 residents in Ulsan, Suwon and Asan, and the concentration of heavy metals in the blood and urine were also analyzed. In case of blood lead concentration, Ulsan $2.27{\mu}g/dl$, Suwon $2.08{\mu}g/dl$, and Asan $1.75{\mu}g/dl$, the high peak in Ulsan, and the low peak in Asan. In case of cotinine concentration, Ulsan smoking($609.16{\mu}g/g{\_}ct$) is higher than nonsmoking($74.07{\mu}g/g{\_}ct$), as Suwon and Asan smoking($416.72{\mu}g/g{\_}ct$, $903.21{\mu}g/g{\_}ct$) is higher than nonsmoking($72.72{\mu}g/g{\_}ct$, $18.06{\mu}g/g{\_}ct$), smoking group is higher than nonsmoking group in all areas revealed statistically significant correlation(p<0.01). In considering results synthetically, these study results are an aid to constructing environmental health science-side heavy metal management measure education programs for normal residents.

  • Since the effect of environmental education at class using textbooks or materials related to environment is limited, the importance of activities for field experience is getting increased day by day. Thereby, the education tends to change into the type of education providing students with direct environmental experience. Students attending the science high school have excellent aptitude and ability for science and will lead the development of science in the future. Now it is urgent to develop various experiential programs which are helpful for them to establish desirable values on environment. However, the field of environmental education that allows science high school students equipped with ample environmental knowledge to improve environment sensitivity and have proper environment awareness is quite restricted as of now. Natural exploration activities are the programs which provide science high school students having lack of chance for environmental education with good opportunities to contact nature and also play significant roles in arousing their interest in issues related with environment. Therefore, it is thought that they will let science high school students explore the natural features of Korea, understand the importance of preserving environment and ecosystem profoundly, and encourage environmental awareness and will of environmental practice. Thereupon, with the study subjects of 121 first and second graders at U Science High School, this article analyzed their recognition of the necessity for environmental education and environmental pollution problems before and after the natural exploration activities, and conducted a survey on their satisfaction after the natural exploration activities and analyzed it. The result of this research is as follows. First, it was shown that the natural exploration activities were effective to raise the science high school students' awareness of issues related with environmental pollution. Second, the natural exploration activities had effect upon enhancing the students' willingness of environmental practice. Third, there was statistically significant correlation between the science high school students' satisfaction with the natural exploration activities and their achievement in the science subject. Fourth, there also was a statistically non or weakness significant correlation between their satisfaction with the natural exploration activities and preference for the science subject. In particular, it was found that students preferring biology indicated higher satisfaction.
