The purposes of this study were to evaluate the distribution of quinolone and to investigate the effects of quinolones (enrofloxacin, ciprofloxacin) in blood(plasma) and eggs of laying hens. Animals were fed quinolones which supplemented with 20, 50, 80㎎/㎏ of body weight. Blood and egg samples were collected after oral administration and analyzed for quinolones(enrofloxacin, ciprofloxacin) by HPLC. In laying hens, the residue period of enrofloxacin were longer than that of ciprofloxacin and the levels of residues were elavated by drug dosage.

This study was conducted to investigate the seasonal variation characteristics of phytoncide in trail of Ulsan Metropolitan. Air samples were collected from May to December 2011. They were collected using Tenax Ta tube and phytoncides were detected and quantified using a Gas Chromatograph Mass Spectrometer (GC/MSD). This study are summarized as follows; The seasonal concentrations of phytoncide are Munsu Mt. 272.3 ㎍/㎥, Samho Mt. 192.4 ㎍/㎥, Shinbul Mt. 50.9 ㎍/㎥, Sibli Bamboo forest 22.4 ㎍/㎥and Joongbu Fire Station 24.4 ㎍/㎥. In Munsu Mt., Samho Mt. and Shinbul Mt. major component ratio is α-Pinene >β-Pinene+Myrcene >Limonene >Camphene >γ-Terpinene >α-Terpinene. Bamboo forest and Joongbu fire station major component ratio is α-Pinene >Limonene >β-Pinene+Myrcene >Camphene >α-Terpinene. The variation of seasonal concentration is summer >spring >fall >winter. The phytoncide concentration of coniferous forest(Munsu Mt., Samho Mt.) is higher than broadleaf forest(Shinbul Mt.).

This study was conducted to investigate the timely characteristics of phytoncide in forest trail of Ulsan Metropolitan. Air samples were collected from July to October 2011. The phytoncide were detected and quantified using a Gas Chromatograph Mass Spectrometer(GC/MSD). This study are summarized as follows ; The highest levels of phytoncide concentration of August is higher than other months in Munsu Mt. and Samho Mt.(town mountains). The higher phytoncide emission rates found in the morning and in the evening. The concentration of phytoncide was understanded to be greatly influenced by environment change of day time.
