Abstract

In order to find out pollutants in leaves of pinus thunbergii, and relationship between pollutants in soil and leaves of pinus thunbergii surrounding Onsan Industrial Complex in Korea, this study was performed. Concentrations of water-soluble sulfur of P. thunbergii leaves were a range of 0.06%-0.25%, but at the vicinity of industrial complex, it was judged to be hindered in growing trees as a range of 0.13%-0.25%. In P. thunbergii leaves the contents of Fe, Mn, Zn and Cu were showed as a range of 87.2 ppm-319.8 ppm, 100.0 ppm-581.3 ppm, 39.0 ppm-134.0 ppm and 1.2 ppm-4.8 ppm, respectively, and they were generally high at P. thunbergii leaves of the vicinity of refinery of industrial complex. But concentrations of Cu and Pb only showed little contents. In the correlation between soil and leaves pollutants, there were significant correlation between total S and water-soluble S(r=$643^{\ast}$), between Fe(r=$0.681^{\ast}$), Zn(r=$0.832^{{\ast}{\ast}}$)), and Cd(r=$0.775^{{\ast}{\ast}}$) in soils and those in P. thunbergii leaves at 10% or 5% level, respectively, and as these results, it was inferrec that heavy metals in soils had relations with those in leaves.

대기오염지역(大氣汚染地域)인 온산공단주변(溫山工團周邊) 해송엽(海松葉)의 엽에(葉) 대한 오염물질분석(汚染物質分析) 및 토양(土壤)과 엽(葉)의 오염물질간(汚染物質間)의 상관분석(相關分析)을 실시(實施)한 결과(結果), 해송엽(海松葉)에 대(對)한 수용성류황함량(水溶性硫黃含量)은 0.06-0.25%이었으나 공단주변(工團周邊)에서는 0.13-0.25%로 높게 나타나 해송엽(海松葉)의 생육(生育)에 지장(支障)을 줄것으로 판단(判斷)되었으며, 엽중(葉中) 중금속함량(重金屬含量)은 Fe은 87.2 ppm-319.8 ppm, Mn은 100.0 ppm-581.3 ppm, Zn은 39.0 ppm-134.0 ppm Cd은 1.2 ppm-4.8 ppm으로 나타나 일반적(一般的)으로 온산공단(溫山工團) 제련소주변(製鍊所周邊)의 해송엽(海松葉)에서 높게 나타났고, 공단(工團)에서 배출(排出)되는 이들 중금속(重金屬)들은 해송(海松)에 영향(影響)을 주고 있다고 볼 수 있었으나, Cu와 Pb은 전(全) 조사지(調査地)에서 미량(微量)만 나타나 아직은 식물피해(植物被害)에 큰 영향(影響)은 없었다. 토양(土壤)과 해송엽중(海松葉中) 오염물질간(汚染物質間)의 상관분석(相關分析)에서는 토양중(土壤中)의 유황함량(硫黃含量)과 엽중(葉中) 수용성유황(水溶性硫黃) 함량간(含量間)에는 5%수준(水準)에서, 토양중(土壤中)의 Fe, Zn, Cd과 엽중(葉中) Fe, Zn, Cd간(間)에도 5% 및 1%의 수준(水準)에서 유의성(有意性)이 인정(認定)되어 토양(土壤)속의 이들 중금속(重金屬)과 엽중(葉中) 중금속간(重金屬間)에는 밀접(密接)한 관계(關係)가 있었다. 그러나 Mn에서는 상관(相關)이 없었다.
