The leaves of three plant species, such as soybean, raspberry, and kudzu, exposed to hydrogen fluoride was collected in an area surrounding an emission source where the release accident occurred. The ultrasonic-assisted extraction and analysis of fluoride by ion chromatography was carried out. The mean concentration of fluoride in the leaves of three plant species exposed to hydrogen fluoride was $5,409{ pm}1,198mg ;F/kg ;dry ;wt$ and $788{ pm}339mg ;F/kg ;dry ;wt$ , respectively. The mean fluoride concentration in ambient air were estimated to be $2.36{ pm}0.65mg/m^3$ ( $2.89{ pm}0.79ppm$ ) and $0.35{ pm}0.15mg/m^3$ ( $0.43{ pm}0.19ppm$ ) in exposed and unexposed sites, respectively. It seems likely that the passive monitoring using plant leaves could identify with respect to plant risk by fluoride in atmosphere. |
