Removal of heavy metals by water hyacinth, Eichhornia crassipes Solms-Laub, was examined with two heavy metals Cd, Cu under laboratory conditions. Cd in culture solution was reducd to 0.116, 0.873, 2.015, 3.755 and 4,747 ㎎/L from 1, 2, 3, 4 and 5 ㎎/L for 24 hrs, after cultivating of water hyacinth respectively And, Cu was reduced to 0.086, 0.600, 2.174, 3.473, and 4.365 ㎎/L from 1, 2, 3, 4, and 5 ㎎/L for 24 hrs, after the cultivation, respectively. Cu was removed faster than Cd nd airating cultivation was effected higher than fixing cultivation. Removal effect of heavy metals by water hyacinth was higher in low a heavy metal cocentration than in high concentration

농산물 탄소성적표지제도 도입을 위한 농업분야 LCI database에 대한 연구를 위하여 쌀의 생산체계를 대상으로 전과정평가를 수행하였다. LCI 구축을 위한 영농 투입물과 산출물에 대한 데이터 결과 유기질비료와 복합비료가 각각 4.29E-01 kg kg<SUP>-1</SUP>rice, 2.30E-01 kg kg<SUP>-1</SUP> rice으로 영농단계에서 가장 높은 투입량을 보였고, 영농단계에서 발생하는 직접대기배출물이 3.23E-02 kg kg<SUP>-1</SUP> rice의 배출값을 나타내었다. 쌀 생산체계에서 발생하는 온실가스를 중심으로 전과정 목록 분석을 수행한 결과 탄소성적값은 8.70E-01 kg CO₂-eq. kg<SUP>-1</SUP> rice이었다. 이 중 CO₂가 7.02E-01 kg CO₂-eq.kg<SUP>-1</SUP> rice로 온실가스 발생의 약 80%가 CO₂였고, CH₄과 N₂O의 배출량은 각각 13%, 5%의 비중을 차지하였다. 전과정 영향평가 결과 지구온난화에 기여하는 주요인자는 유기질비료 생산 공정이 42%, 무기질비료 생산공정이 40%로 비료생산공정에 의한 비중이 가장 높았다. LCA (Life Cycle Assessment) carried out to estimate carbon footprint and to establish of LCI (Life Cycle Inventory) database of rice production system. The results of collecting data for establishing LCI D/B showed that organic fertilizer and chemical fertilizer input to 4.29E-01 kg kg<SUP>-1</SUP> rice and 2.30E-01 kg kg<SUP>-1</SUP> rice for rice cultivation. It was the highest value among input for rice cultivation. And direct field emission was 3.23E-02 kg kg<SUP>-1</SUP> during rice cropping. The results of LCI analysis focussed on greenhouse gas (GHG) was showed that carbon footprint was 8.70E-01 kg CO2-eq. kg<SUP>-1</SUP> rice. Especially for 80% of CO2 in the GHG and 7.02E-01 kg of its CO2-eq. kg<SUP>-1</SUP> rice. Of the GHG emission CH4, and N2O were estimated to be 13% and 5%, respectively. With LCIA (Life Cycle Impact Assessment) for rice cultivation system, it was observed that fertilizer process might be contributed to approximately 80% of GWP (global warming potential).

고추생산체계에 대한 탄소성적을 평가하기 위하여 노지재배 (건고추)와 시설재배 (풋고추)로 구분하여 LCI database 구축하고 전과정 영향평가를 통한 잠재적 환경영향을 평가하였다. LCI 구축을 위한 영농 투입량과 배출물 산정결과 고추 1 kg 생산의 비료 사용량은 노지재배가 2.55E+00 kg kg<SUP>-1</SUP> redpepper로 시설재배의 7.74E-01kg kg<SUP>-1</SUP> greenpepper 보다 많았다. 농약 투입은 노지재배와 시설재배가 각각 5.38E-03 kg kg<SUP>-1</SUP> redpepper, 2.98E-04 kg kg<SUP>-1</SUP> greenpepper으로 노지재배에서의 농약투입량이 훨씬 높았다. 고추생산 중 대기로 배출된 CO₂, CH₄, N₂O의 합은 노지고추가 5.84E-01 kg kg<SUP>-1</SUP> redpepper, 2.81E+00 greenpepper로 시설고추가 높았다. 고추 생산체계에 대한 탄소원단위성적 산정결과 노지재배가 4.13E+00 kg CO₂-eq. kg<SUP>-1</SUP> redpepper, 시설재배 풋고추가 4.70E+00 kg CO₂-eq. kg<SUP>-1</SUP> greenpepper였다. 시설재배 (풋고추)는 CO₂발생량이 많았고, 노지재배 (건고추)는 CH₄와N₂O 발생량이 많았다. 전과정 영향평가 결과 GWP의 특성화값은 노지재배가 4.13E+00kg CO₂-eq. kg<SUP>-1</SUP>, 시설재배가 4.70E+00 kg CO₂-eq.kg<SUP>-1</SUP>이었고, GWP범주에 대한 기여도는 노지재배가 약 52%, 시설재배 약 48%로 거의 비슷하였다. LCA (Life Cycle Assessment) carried out to estimate carbon footprint and to establish of LCI (Life Cycle Inventory) database of pepper production system. Pepper production system was categorized the field cropping (redpepper) and the greenhouse cropping (greenpepper) according to pepper cropping type. The results of collecting data for establishing LCI D/B showed that input of fertilizer for redpepper production was more than that for greenpepper production system. The value of fertilizer input was 2.55E+00 kg kg<SUP>-1</SUP> redpepper and 7.74E-01 kg kg<SUP>-1</SUP> greenpepper. Amount of pesticide input were 5.38E-03 kg kg<SUP>-1</SUP> redpepper and 2.98E-04 kg kg<SUP>-1</SUP> greenpepper. The value of field direct emission (CO2, CH4, N2O) were 5.84E-01 kg kg<SUP>-1</SUP> redpepper and 2.81E+00 greenpepper, respectively. The result of LCI analysis focussed on the greenhouse gas (GHG), it was observed that the values of carbon footprint were 4.13E+00 kg CO2-eq. kg<SUP>-1</SUP> for redpepper and 4.70E+00 kg CO2-eq. kg<SUP>-1</SUP> for greenpepper; especially for 90% and 6% of CO2 emission from fertilizer and pepper production, respectively. N2O was emitted from the process of N fertilizer production (76%) and pepper production (23%). The emission value of CO2 from greenhouse production was more higher than it of field production system. The result of LCIA (Life Cycle Impact Assessment) was showed that characterization of values of GWP (Global Warming Potential) were 4.13E+00 kg CO2-eq. kg<SUP>-1</SUP> for field production system and 4.70E+00 kg CO2-eq. kg<SUP>-1</SUP> for greenhouse production system. It was observed that the process of fertilizer prodcution might be contributed to approximately 52% for redpepper production system and 48% for greenpepper production system of GWP.
