Abstract

The Seonamsa temple is located on steep terrain surrounded by forests and valleys, and is a place that the temple is scared of biological damage because it has high humidity and low wind levels. Therefore, we investigated a concentration and diversity of airborne fungi in indoor and outdoor by collecting air each season. The outdoor fungal load was far higher in spring ($276CFU/m^3$), autumn ($196CFU/m^3$), summer ($128CFU/m^3$) than in winter ($24CFU/m^3$). The lowest located Jijangjeon and upper located Wontongjeon showed the highest distribution of $337.4CFU/m^3$ in summer and $333.4CFU/m^3$ in autumn, respectively. Summer is the season with large variations in the concentration of airborne fungi between indoor and outdoor, a concentration of airborne fungi in indoor was maximum three times higher than these in outdoor with $128CFU/m^3$. Although the most fungi were collected in spring, fungal diversity was richer in summer and autumn with 28 genera 45 species and 25 genera 47 species, respectively. In particular, the concentration of airborne fungi was the most highest in all sampling sites in autumn, of which Ascomycota members accounted for 86% and Cladosporium genus was dominated. The most kind of Penicillium (16 species) was mainly distributed in indoor air in summer, autumn and winter.

순천 선암사는 산림과 계곡으로 둘러싸여 가파른 지형에 위치하고 있으며 평지보다 온 습도는 높고 바람의 세기가 약하여 생물 피해가 우려되는 곳이다. 이에 계절마다 진균상 조사를 통해 실내 외 공기질에 분포하는 진균의 농도와 다양성을 조사하였다. 외부 공기질에 분포하는 진균의 농도는 봄($276CFU/m^3$)에 가장 높았고, 가을($196CFU/m^3$), 여름($128CFU/m^3$), 겨울($24CFU/m^3$) 순으로 감소하였다. 가장 하단에 위치한 지장전은 여름철에 $337.4CFU/m^3$, 가장 상단에 위치한 원통전은 가을철에는 $333.4CFU/m^3$의 가장 높은 농도를 나타냈다. 실내 외 공기질에서 부유균 농도의 차이가 컸던 계절은 여름철이었으며 $128CFU/m^3$인 외부보다 실내 공기질에 최소 0.5배에서 최대 3배 정도의 많은 진균이 부유하고 있었다. 부유 진균이 가장 많이 수집된 계절은 봄철이었지만 다양성은 여름과 가을철 공기질에서 더 높았는데 여름에는 28속 45종, 가을에는 25속 47종의 진균이 확인되었다. 특히, 가을철에는 모든 조사 지점에서 부유 진균의 분포도가 가장 높았는데 그 중에서 자낭균이 86%를 차지하였고 Cladosporium속이 우점하였다. Penicillim속은16종이 검출되어 종다양성이 가장 높았고 야외보다는 여름과 가을, 겨울철의 실내 공기질에 주로 분포하였다.
