Abstract

This study was conducted to investigate the distribution and variation of the anion and cation number of aerosols in the A and B regions of Gyorae forests. Ions were measured using an ion number meter between 28 June and 13 July 2017. The total average number of anions and cations were $735ions/cm^3$ and $459.27ions/cm^3$, respectively, which were measured at five sites in A area at average temperature of $27.81^{\circ}C$, wind speed of 0.28 m/sec, and altitude of 455.7 m. The average number of anions and cations were $780ions/cm^3$ and $379.55ions/cm^3$, respectively, which were measured at all four sites in the B region at average temperature of $27.6^{\circ}C$, humidity of 80%, wind speed of 0.1 m/sec and altitude of 477 m. The number of anions and cations in the A and B regions was $757.5ions/cm^3$ and $419.41ions/cm^3$, respectively. The number of ions was highly variable for each measurement over time. The number of anions remained $275.73ions/cm^3$ higher than that of cations. The variance of the measured values of anions and cations between and within sites A and B was significant (p<.001) and there was a significant positive correlation between regional mean values of anions and cations. In conclusion, the temporal distribution and variation of the ion content in the Gyorae forests provide basic information regarding aerosol compositions and changes.

본 연구는 교래자연휴양림 지역을 A와 B 지역으로 나누어서 대기질의 음이온과 양이온수를 측정하여 일별 그 분포와 변이에 대한 연구가 목적이었다. 이온수 측정은 이온수 측정기로 2017년 6월 28일-7월 13일 사이에 실시하였다. A지역의 5개 지점의 전체 평균 음이온수는 $734.5ions/cm^3$, 양이온 수는 $463.3ions/cm^3$, 대기온도는 $25.51^{\circ}C$, 습도는 81.6%, 풍속은 0.28 m/sec, 해발 고도는 455.7 m 이었다. B지역의 4개 지역 전체 측정한 평균 음이온수는 $780ions/cm^3$, 양이온수는 $379.55ions/cm^3$, 대기온도는 $27.6^{\circ}C$, 습도는 80%, 풍속은 0.1 m/sec, 측정지역의 해발고도는 477 m 이었다. 교래지역 A와 B전체의 음이온수의 평균치는 $757.5ions/cm^3$, 양이온수의 평균치는 $419.41ions/cm^3$이었다. 이온의수는 시간별로 측정별로 변이성이 높았다. 음이온수가 양이온수보다 평균 $275.73ions/cm^3$ 만큼 더 높게 유지되었다. A와 B점의 음이온과 양이온수의 측정치를 Pearson 분산분석에서는 음이온 측정지점별 및 측정지점 내의 분석이 유의하게 나타났으며(p<.001), 양이온의 측정지점별 및 측정지점 내의 분석에서도 유의하게 나타났다(p<.001). 음이온과 양이온수의 지역별 평균측정치 간의 상관관계분석에 서 r=.386으로 유의한 정적인 상관관계가 있었다(p<.001). 결론적으로 상기 음이온과 양이온 함량의 시간적 분포와 변이를 나타낸 결과는 교래자연휴양림의 대기질의 성분과 변화에 대한 기초정보를 제공하고 있다고 본다.
