한국에서 관측된 산성강수와 대륙적인 중국의 대기오염 이동

정용승,김학성,박기현 한국교원대학교 환경과학연구소 2002 환경연구논문집 Vol.- No.7

1990년부터 청원(KHN)의 농촌기역에서 산성강우가 관측되었다. 청원의 10년 관측과 함께 다른 6개의 배경 관측소에서도 강우가 채집 및 분석되었다. 산성비는 전 관측에서 자주 발생되었다. KHN 에서는 다른 10년의 강수량 가중평균 VWM 값이 4.67이고 산술평균 값은 5.09이다. 일반적으로, 봄 철 황사가 발생될 때 pH 값이 높았으며, 여름철에는 비교적 중성 값을 보였다. 다른 계절에는 산성 강수가 대개 기류와 관련되었으며, 중국의 중부와 남부지방에서 오는 기류와 저기압은 한반도에서 낮은 pH 값을 발생시켰다. 1996년부터 인공위성을 이용 동아시아 대기오염의 장거리 이동을 모니터링하고 있으며, 황해를 지나 한반도에 이동되는 대기오염의 장거리 이동 사례를 많이 수집하였다. 한국의 산성비는 중국의 발원지로부터 공기의 지나온 분석, 산성 안개와 박무도 논의 되었다. Acid rain at a rural site in Chongwon(KHN), central Korea has been under observation since 1990. To substantiate the 10-year observations, rain samples from six other sites were also collected and analyzed. Results show that acid rain occurred frequently at all sites, At KHN, seasonal and annual variability of pH values had a 10-year VWM value of 4.67 and an arithmetic mean value of 5.09, In general, a high value of pH occurred during springtime when the occurrence of yellow sand (dust) was prevalent in East Asia; during summer, heavy rain usually contained neutral pH values. During other seasons, the degree of acidic precipitation usually coincided with certain air flows. Most frequently, air flows and cyclones coming from south and central China often resulted in precipitation with low pH values observed in Korea. Using daily satellite observations from 1996, we have also been monitoring the large-scale transport of air pollutants over East Asia. Many samples of long-range transport of air pollutants (LRTAP) were obtained when they were crossing the Yellow Sea and moving over the Korean Peninsula. Cases of acid rain in Korea clearly correlate wth the LRTAP from source regions in China. In this study, results of air-parcel trajectory, plus acid fog and mist analysis are discussed.

同位元素 ?? 肥科施用에 따른 水稻의 窒素吸收에 關한 硏究 (其5) : (綜合編)

金正基 東亞大學校 1976 東亞論叢 Vol.13 No.1

重窒素(N-15)를 利用한 窒素質 肥料 施用에 依한 水稻의 中間 落水處理 窒素의 吸收, 施用(肥料)窒素와 地中窒素와의 關係, A-Value 및 E. R. A 測定 그리고 玄米의 蛋白質 含量과의 關係를 測定調査한 結果 얻어진 結論은 다음과 같다. 1. 硫安施用은 尿素施用에 比해 玄米中 蛋白含量을 增加시켰다. 2. 硫安의 追肥施用은 玄米 蛋白量을 增大시키는 傾向이었다. 3. 藁의 蛋白質量이 많을수록 玄米의 蛋白含量이 增加되었다. 4. 玄米中 施用硫安의 窒素含有率이 높을수록 玄米 蛋白質含量이 높은 傾向이 보였다. 5. 草長 및 分蘗에 있어서 各處理間에는 有意的인 差異가 認定되지 안했으나 草長은 落水處理區에서 後期 生育이 增大된 傾向이 있었고, 분열은 生育 後期에 抑制(無效分蘗)된 傾向이 있었다. 6. 中間 落水 處理가 大體로 收量 構成要素에서 數値의 增大 傾向을 보였고 中間 落水, 肥料種類 그리고 品種 등 各要因의 交互作用에서 登熟率, 姙實率 그리고 千粒重에서 有意的인 差異를 나타냈다. 7. 全窒素 含量에서 精粗, 玄米, 그리고 藁는 모두 中間 落水 處理 및 肥料에서는 有意差가 認定되지 안했으나 品種에서만은 藁 및 玄米가 有意差를 보였다. 8. 施用肥料(肥料窒素??)의 水稻體 含有率은 全窒素와의 對比에서 基肥는 3%~4%追肥는 8.5%~9.5% 程度였고 施用 窒素와 地中 窒素와의 對比는 11.5%~13% 程度였다. 9. 移秧期의 A-Value 測定値는 粗穀, 藁 모두 幼穗形成期의 그것에 比해서 높았다. 10. 移秧期 및 幼穗形成期에서 硫安이 A-Value는 尿素에 比해 粗穀, 藁 모두 컸다. 11. 移秧期의 E.R.A. 測定値는 粗穀, 藁 함께 幼穗形成期의 測定値에 比해 작았다. 12. 硫安의 E.R.A. 測定値는 粗穀, 藁 모두 尿素에 比해 그 數値의 增大傾向이 나타났다. 13. 移秧時의 施用肥料의 效率이 적을수록 그리고 地中肥料의 量이 클수록 玄米量을 增加시키는 傾向이 보였다. 14. 地中窒素(土壤中 肥料)의 有效量과 土壤 全窒素量(0~10㎝)과의 對比는 粗穀에서 9.9%~41.8%였고, 藁에서는 6.7%~35.6% 였다. A field experiment using the split-plot design was conducted at two experimental sites, namely; Seoul and Pusan, to investigate the effect of water management (mid-term drainage vs. continuous flood), time of fertilizer-N application (at transplanting vs. primodial initiation) and efficiency of fertilizer-N carrier in paddy rice. In the study two high yielding rice varieties were used: Nongkwang, as a local variety and Bongkwang as an introduced variety. Water management was considered the main plot with the other effects:time of fertilizer-N application and efficiency of fertilizer as sub-plots. To determine the interactions labelled N-15 fertilizers: urea and ammonium sulfate were used. The experimental design followed both a Seoul and Pusan experiment sites was in accordance with IAEA guidelines. Individual Plot size is 4×1.25m and each plot divided into thrce sub-plots by plastic sheet. Each sub-plot was labelled A, B, and C. Sub-plot A and B were for N-15 fertilizer application while sub-plot C for non-labelled nitrogen fertilizer application. The area of sub-plot A is 1×1.25m sub-plot B, 0.75×1.25m; and subplot C, 2.25×1.25m. Plant density was 4 plants per hill planted in rows of 25×25㎝. The various treatment were arranged in a split-plot design with two water managements as the main plot and the N-fertilization plus varieties as subplot. Each treatment replicated four times. Water was maintained continuously on the plot during the whole growing period. When 50% of the plants had reached the primordial initiation stage nitrogen fertilizer was applied 2 days after the plots were fully drained, and immediately reflooded. Each plot was divided into sub-plot A, B, and C with the plastic sheet. One sub-plot, either A or B, received N-15 labelled fertilizer at transplanting and non-labelled N at primordial initiation. The other sub-plot received non labelled N at transplanting and N-15 labelled fertilizer at primordial initiation stage. Sub-plot C received non labelled fertilizer. The labelled fertilizer-N were obtained from JUNTA DE ENERGIA NUCLEAR. Urea labelled on both nitrogen atome was prepared by the reaction of ?? with diphenyl carbonate at high pressure under helium atmosphere. The product was purified by recrystallyzation from ethanol or acetone. Isotopic enrichment was 1.37%. Ammonium sulfate was producted by the reaction of ?? with sulfuric acid. Nursery management was done in accordance with customary practices followed at each experimental site. Total amount of potassium chloride applied was 8㎏/ha, potassium of which half was treated at transplanting time and primordial initiation stage respectively. As basal application 8㎏/ha of phosphate was supplied in the form of super-phosphate at both sites. A day before transplanting, fertilizers mixed with fine sand at 1 to 1 ratio were broadcast by hand. Watermanagement-Water level in each plot was continuously maintained above 5cm from soil surface for the duration of the experiment except for mid-term drained treatment. For the mid-term drainage treatment, the plots were drained for two days and reflooded immediately after the addition of the fertilizers. Appropriate agro-chemicals consisting of weedicide and insecticide were applied to control weeds and to protect the plants from insects and rice blast disease. Resulted of the various interactions were evaluated in terms of A-value and ERA. Water management, continuous flooding vs. mid-term drainage have no significant effect on A-value. However, significant differences were observed in time of fertilizer-N application and in fertilizer-N carrier. On time of fertilizer-N application A-value were increased at transplanting time as compared to that at primordial initiation. Results indicate that young rice seedling utilizes more soil nitrogen than at later states of development. On fertilizer-N carrier, ammonium sulfate was observed to be a better source of nitrogen than urea. Significant varietal difference was also observed between the two varieties used in this study. Bongkwang contained higher nitrogen percentage in grain than Nongkwang regardless of experimental sites. When ammonium sulfate was applied, % NDFF was increased regardless of varieties at Seoul site where-in A-value is less than that of Pusan. As far as timing of application, nitrogen fertilizer applied at primordial initiation was more favorable than at transplanting regardless of varieties and fertilizer-N carrier, and the results abbreviated were as follows; 1. Protein contents in hulled grain were increased by applying ammo-sulfate as compared with urea. 2. Protein contents in hulled grain were increased by top dressing of ammosulfate. 3. The more protein in straw, the more protein in hulled grain. 4. Protein amounts in hulled grain were increased in accordance with the nitrogen (??) amounts applied. 5. No obvious difference was appeared between the treatment of mid-term drainage and control in terms of plant height and number of tillers; but the later growth on plant height was accerelated in the plots of mid-term drainage as compared with the plots, control; while the number of tiller per-hill was decreased at the later growing season. 6. Statistically high significance in Nongkwang variety was appeared almost all the items of yield components, interaction among mid-term drainage fertilizer application and variety was shown in terms of maturing rate, seed-bearing rate and weight of 1,000 kernels. No statistical significance expect the length of ears was found in mid-term drainage treatment in each terms of yield components, and the values observed were increased, and the application effect of urea and Ammonium sulfate in the factor of fertilizer application was not revealed. 7. Statistically significant difference between the treatments of mid-term drainage and fertilizer applied was not shown in % of total nitrogen of rough grain, hulled grain was revealed in factor of variety. 8. Contents of nitrogen applied in rice plant (nitrogen fertilizer traced with ?? Isotope) at transplanting was assumed approximately 3-4% as compared with nitrogen, and 10% was contained by top dressing applied at primordial stage. 9. At the time of fertilizer-N application, regardless of Fertilizer-N carrier, A-value at transplanting time was higher than that at primordial initiation. 10. A-value of ammonium sulfate applied at transplanting time, both grain and straw was higher as compared with urea. 11. Nitrogen application at primordial initiation stage significantly increased an effective rate of application (E.R.A) as compared with the stage of transplanting both in grain and straw. 12. E.R.A. measurement in the treatment of ammonium sulfate increased as compared with urea. 13. Increasing trend appeared in the weights of hulled grain, as the effective rate of application is lower, and A-value is bigger. 14. The ratio of A-value to soil total nitrogen ranges from 9.9% to 41.8% in grain and 6.7% to 35.6% in straw.
