콩나물의 성장은 콩의 수침 및 주수시 용존오존농도 0.3 ppm으로 처리하였을때가 가장 양호하였다. 콩의 수침시 용존오존농도 0.3 ppm으로 30분간 처리하여 5일간 재배한 콩나물의 배축신장도는 무처리보다 19%가 높았으며 시루당의 총중량은 27%가 증가하였다. 반면에 뿌리의 중량은 27%가 감소하였다. 그러나, 수침시와 주수시 처리와 수침시 처리 사이의 성장도 차이는 뚜렷하지 않았다. Carbendazim, captan, diazinon, fenthion, dichlorvos 및 chlorpyrifos 등 6종의 농약을 $4.75{sim}8.35;ppm$으로 오염시킨 콩의 수침과정 및 5일간 재배중의 잔류농약의 자연분해율은 $85{sim}99%$였으나 주수시 0.3 ppm의 오존수로 처리하였을 때는 $89{sim}100%$, 수침시와 주수시에 처리하였을 때는 $94{sim}100%$이였다. 또 농약별 오존수에 의한 분해율은 captan>dichlorvos>fenthion>carbendazim>diazinon>chlorpyrifos순이였다.
This study was conducted to investigate the effect of ozone treatment on the growth and pesticide-residual contents of soybean sprouts during cultivation. Total weight and length of the soybean sprouts treated by 0.3 ppm ozone water for 30min during soaking of soybean increased 27% and 19% higher than those of control group, respectively. But 27% of root weight decreased. No major differences in growth state were observed between the treatments during soaking and watering with ozone water, and watering with ozone water. Pesticide residues in soybeans treated with carbendazim, captain, diazinon, fenthim, dichlorvos and chlorpyrifos ranged from 4.75 to 8.35 ppm. The pesticides in soybean sprouts by the treatment of soaking and watering with water for 5 days, those by 0.3 ppm ozone-water watering, and those by soaking and watering with 0.3 ppm ozone water were destroyed to $85{sim}99$, $89{sim}100$ and $94{sim}100%$, respectively. The order of degradation ratio in the pesticides was captan>dichlorvos>fenthion>carbendazin>diazinon>chlorpyrifos.
