| 1 | Effects of humic acid on phytodegradation of petroleum hydrocarbons in soil simultaneously contaminated with heavy metals显示文摘The use of humic acid (HA) to enhance the efficiency of phytodegradation of petroleum hydrocarbons in soil contaminated with diesel fuel was evaluated in this study. A sample of soil was artificially contaminated with commercially available diesel fuel to an initial total petroleum hydrocarbons (TPH) concentration of 2300 mg/kg and four heavy metals with concentrations of 400 mg/kg for Pb, 200 mg/kg for Cu, 12 mg/kg for Cd, and 160 mg/kg for Ni. Three plant species, Brassica campestris, Festuca arundinacea, and Helianthus annuus, were selected for the phytodegradation experiment. Percentage degradation of TPH in the soil in a control pot supplemented with HA increased to 45% from 30% without HA. The addition of HA resulted in an increases in the removal of TPH from the soil in pots planted with B. campestris, F. arundinacea, and H. annuus, enhancing percentage degradation to 86%, 64%, and 85% from 45%, 54%, and 66%, respectively. The effect of HA was also observed in the degradation of n-alkanes within 30 days. The rates of removal of n-alkanes in soil planted with B. campestris and H. annuus were high for n-alkanes in the range of C11-C28. A dynamic increase in dehydrogenase activity was observed during the last 15 days of a 30-day experimental period in all the pots amended with HA. The enhanced biodegradation performance for TPHs observed might be due to an increase in microbial activities and bioavailable TPH in soils caused by combined effects of plants and HA. The results suggested that HA could act as an enhancing agent for phytodegradation of petroleum hydrocarbons in soil contaminated with diesel fuel and heavy metals. | Soyoung Park Ki Seob Kim Jeong-Tae Kim Daeseok Kang Kijune Sung | 2011 | Journal of Environmental Sciences2011，23，12： | 2 |

| 7 | Spatio-temporal change in forest cover and carbon storage considering actual and potential forest cover in South Korea显示文摘This study analyzes change in carbon storage by applying forest growth models and final cutting age to actual and potential forest cover for six major tree species in South Korea. Using National Forest Inventory data, the growth models were developed to estimate mean diameter at breast height, tree height, and number of trees for Pinus densiflora, Pinus koraiensis, Pinus rigida, Larix kaempferi, Castanea crenata and Quercus spp. stands. We assumed that actual forest cover in a forest type map will change into potential forest covers according to the Hydrological and Thermal Analogy Groups model. When actual forest cover reaches the final cutting age, forest volume and carbon storage are estimated by changed forest cover and its growth model. Forest volume between 2010 and 2110 would increase from 126.73 to 157.33 m3 hm-2. Our results also show that forest cover, volume, and carbon storage could abruptly change by 2060. This is attributed to the fact that most forests are presumed to reach final cutting age. To avoid such dramatic change, a regeneration and yield control scheme should be prepared and implemented in a way that ensures balance in forest practice and yield. | NAM Kijun LEE Woo-Kyun KIM Moonil KWAK Doo-Ahn BYUN Woo-Hyuk YU Hangnan KWAK Hanbin KWON Taesung SUNG Joohan CHUNG Dong-Jun LEE Seung-Ho | 2015 | Science China(Life Sciences)2015，58，7： | 1 |

| 10 | 石油烃污染土壤中腐植酸对草本植物吸收重金属的影响显示文摘本文研究了重金属和石油烃复合污染土壤中,腐植酸对草本植物吸收重金属的影响。结果显示:腐植酸大幅度地降低了污染土壤中可溶性和交换态重金属含量,但提高了植物可利用态重金属含量。土壤添加腐植酸后,除Ni外,重金属潜在生物有效性和可淋出性因子大于1,这表明大多数重金属对植物具有潜在的有效性。此外,腐植酸增加了铅(Pb)、铜(Cu)、镉(Cd)和镍(Ni)在供试植物幼苗和根部的积累,最高的是高羊茅幼苗,达264.7%,生物富集系数从0.30提高到1.10。芸苔根中Ni和Pb的生物富集系数也有所提高。这些研究结果表明,石油烃与重金属同时污染的情况下,加入腐植酸可以促进植物吸收重金属,但降低重金属淋失,防止地下污染。 | Soyoung Park Ki Seob Kim Daesok Kang Hansam Yoon Kijune Sung 陈昊 林启美 | 2014 | 腐植酸2014，，3： | 0 |
| 11 | Lubricant skin on diverse biomaterials with complex shapes via polydopamine-mediated surface functionalization for biomedical applications显示文摘Implantable biomedical devices require an anti-biofouling,mechanically robust,low friction surface for a prolonged lifespan and improved performance.However,there exist no methods that could provide uniform and effective coatings for medical devices with complex shapes and materials to prevent immune-related side effects and thrombosis when they encounter biological tissues.Here,we report a lubricant skin(L-skin),a coating method based on the application of thin layers of bio-adhesive and lubricant-swellable perfluoropolymer that impart anti-biofouling,frictionless,robust,and heat-mediated self-healing properties.We demonstrate biocompatible,mechanically robust,and sterilization-safe L-skin in applications of bioprinting,microfluidics,catheter,and long and narrow medical tubing.We envision that diverse applications of L-skin improve device longevity,as well as anti-biofouling attributes in biomedical devices with complex shapes and material compositions. | Kijun Park Seunghoi Kim Yejin Jo Jae Park Inwoo Kim Sooyoung Hwang Yeontaek Lee So Yeon Kim Jungmok Seo | 2023 | Bioactive Materials2023，，7： | 0 |
