경기도 의정부시에 위치하고 있는 도봉농장내에서 생육하고 있는 조경수목이 인근 공장의 연료연소시 발생되는 $SO_2$ gas에 의해 피해를 입어 고사된 것을 조사한 결과를 요약하면 다음과 같다. 1. 피해수종별 엽내유황함량을 분석한 결과 피해가 심할수록 전유황함량이 증가하는 각수종에서 나타났다. 농장서쪽 경계선에서 $70\~120m$ 거리가 피해가 가장 심하였고, 여기서 전유황함량이 가장 높았다. 또한 전유황함량의 최대치가 $0.5\~0.6\%$인데, 이러한 피해가 발생된 것은 급성적인 피해가 기온의 차이가 큰것에 기인된다. 2. 향나무에서 동일개체내의 건전부위와 피해부위의 전유황함량은 유의적인 차이를 보였다. 2. 엽조직의 해부학적 조사에서 피해엽은 공통적으로 갯솜조직과 표피세포의 원형질분리가 일어나 수축 파괴가 일어났고, 또한 세포간극과 기공주변이 넓어진다.

This study was to investigate ornamental trees injuries at the Tobong ornamental tree farm, which is located in Uichongpu City, Kyonggido. The injury was caused by $SO_2$ gas from the smoke of the vicinal factories. The results obtained are as follows: 1 The total concentration of sulfur in leaves was increased with incerased degree of injury The most severe injuries were found at the distance between 70-120m from the western boundary of the Tobong ornamental 4ree farm with a highest concentration of total sulfur at $0.5-0.6\%$. This means the injuries caused by the acute injury and the temperature changes. 2. Significant differences were found between normal and injured portion of the same trees in Juniperus chinensis. 3. Anatomical study of the leaf tissues, showed the plasmolysis occured both in spongy and epidermal cells, leading to shrinkage and destruction. An intercellular space and stomatal periphery became wider.
