Phytoremediation of Soil Contaminated with Crude Oil Using Mucuna Bracteata

引用

Research in Ecology 2019年第1期1卷 20-30页

作者： kuok ho daniel, tang Yu Wei Eric, Law Department of Environmental Engineering Curtin University MalaysiaCDT25098009 MiriSarawakMalaysia

This study examines the ability of Mucuna bracteata DC. to remediate soil contaminated with increasing levels of crude oil up to 20%. It also investigates the effect of fertilizer application on crude oil degradation. Changes in crude oil concentrations, pH and moisture of the soil in eight experimental pots were tracked over a period of 9 weeks. The crude oil levels in soil were analysed as Total Petroleum Hydrocarbons (TPHs) using the UV-Vis spectrophotometer. The study revealed the capacity of Mucuna bracteata to phytoremediate soil contaminated with crude oil in all experimental pots though the plant died at 20% contamination towards the end of the experiment. The plant survived up to 15% contamination with that in the fertilized pot showing better physiological conditions. In all instances, fertilized pots showed higher rates of crude oil reduction. The amounts of crude oil degraded in fertilized pots were also higher except at 20% contamination. The soil pH varied over a narrow range throughout the experimental period. Moisture of soil contaminated with 15% and 20% crude oil was higher than that contaminated with 5% and 10% crude oil. Mucuna bracteata showed signs of phytoextraction which can be subject to further study. This study contributed a new candidate of phytoremediation for soil contaminated with high level of crude oil.

Background:The use of laparoscopic(LLR)and robotic liver resections(RLR)has been safely performed in many institutions for liver tumours.A large scale international multicenter study would provide stronger evidence and insight into application of these techniques for huge liver tumours≥10 ***:This was a retrospective review of 971 patients who underwent LLR and RLR for huge(≥10 cm)tumors at 42 international centers between ***:One hundred RLR and 699 LLR which met study criteria were *** comparison between the 2 approaches for patients with huge tumors were performed using 1:3 propensity-score matching(PSM)(73 vs.219).Before PSM,LLR was associated with significantly increased frequency of previous abdominal surgery,malignant pathology,liver cirrhosis and increased median *** PSM,RLR and LLR was associated with no significant difference in key perioperative outcomes including media operation time(242 vs.290 min,P=0.286),transfusion rate rate(19.2%vs.16.9%,P=0.652),median blood loss(200 vs.300 mL,P=0.694),open conversion rate(8.2%vs.11.0%,P=0.519),morbidity(28.8%vs.21.9%,P=0.221),major morbidity(4.1%vs.9.6%,P=0.152),mortality and postoperative length of stay(6 vs.6 days,P=0.435).Conclusions:RLR and LLR can be performed safely for selected patients with huge liver tumours with excellent *** was no significant difference in perioperative outcomes after RLR or LLR.
