Trace element-contaminated soils(TECSs) are one of the consequences of the past industrial development worldwide. Excessive exposure to trace elements(TEs) represents a permanent threat to ecosystems and humans worldwide owing to the capacity of metal(loid)s to cross the cell membranes of living organisms and of human epithelia, and their interference with cell *** of TE bioavailability in soils is complicated due to the polyphasic and reactive nature of soil constituents. To unravel critical factors controlling soil TE bioavailability and to quantify the ecological toxicity of TECSs, TEs are pivotal for evaluating excessive exposure or deficiencies and controlling the ecological risks. While current knowledge on TE bioavailability and related cumulative consequences is growing, the lack of an integrated use of this concept still hinders its utilization for a more holistic view of ecosystem vulnerability and risks for human health. Bioavailability is not generally included in models for decision making in the appraisal of TECS remediation options. In this review we describe the methods for determining the TE bioavailability and technological developments, gaps in current knowledge, and research needed to better understand how TE bioavailability can be controlled by sustainable TECS management altering key chemical properties, which would allow policy decisions for environmental protection and risk management.

土壤修复主要通过将受污染土壤进行挖掘和填埋,这种方法在进行大量位点修复时不太切合实际,因此要选择其它棕地(brownfield)修复方法。本研究介绍了评估受铜铬砷(CCA)污染土壤采用含铁(Fe)爆破砂(BS)或嵌氧颗粒(OSG)处理后的化学稳定过程。就工业尺度下混合改良物的可行性和在不同氧化还原条件下的稳定效率对这种稳定技术进行了评估。在野外自然条件下,采用1m^3测渗计调查了这种稳定性并在实验室(10L)对氧化还原条件的效应进行了评估。结果表明改良物的添加率最低时(0.1%和1%)化学计量中还有足够的铁,但是不管在野外还是实验室都是采用高添加率的改良物(8%和17%)效果较好。铁和混合物的颗粒大小会影响稳定效率。厌氧条件的发展(模拟自水饱和度)会提高砷(As^(3+))的份额,因此增强了砷的迁移能力。在有氧条件下,采用高浓度OSG提高了孔隙水中镍(Ni)和铜(Cu)的浓度,但是在厌氧条件下,与未作处理的土壤相比,砷的淋溶率降低了,而镍和铜的淋溶并不是关键的。所处理土壤的最终目的决定了改良方案,也就是说,对于在厌氧条件下填埋的土壤,OSG浓度为10%较合适。也可以在有氧条件下将1%的BS与土壤混合,置于填埋区上层或者棕色地块(brownfield site)原处。另外从长期来看,采用BS处理似乎比用OSG处理效果要好。

过去几十年中,污染土壤一直受到公众和科学家双方的关注。国家清查表明,存在大量潜在的污染位点,它们原先是各种工业活动场所。早年的工业技术常常是建立在开放系统基础上的,设计之时没有预见到它们会成为潜在的环境威胁。针对水和空气污染责任组织的诉讼行为导致了水和废气清洁新技术的发展。如今,污染土地在未来可持续土地利用中起着重要作用,不仅是过去的工业活动造成的污染,也包括当前工业技术管理及废物管理。与污染土壤有关的课题是跨学科的。在瑞典北方土壤修复中心

Intrahepatic cholestasis of pregnancy-current achievements and unsolved problems

引用

World Journal of Gastroenterology 2008年第38期14卷 5781-5788页

作者： jurate Kondrackiene Limas Kupcinskas Department of Gastroenterology Kaunas University of MedicineKaunas 50009 Lithuania

Intrahepatic cholestasis of pregnancy （ICP） is the most common pregnancy-related liver disorder. Maternal effects of ICP are mild; however, there is a clear association between ICP and higher frequency of fetal distress, preterm delivery, and sudden intrauterine fetal death. The cause of ICP remains elusive, but there is evidence that mutations in genes encoding hepatobiliary transport proteins can predispose for the development of ICP. Recent data suggest that ursodeoxycholic acid is currently the most effective pharmacologic treatment, whereas obstetric management is still debated. Clinical trials are required to identify the most suitable monitoring modalities that can specifically predict poor perinatal outcome. This article aims to review current achievements and unsolved problems of ICR

Transformative Learning in Language Arts as a Method of Guidance and Counseling

引用

Journal of Literature and Art Studies 2012年第7期2卷 740-750页

作者： jurate Sucylaite Klaipeda University Klaipeda Lithuania

Our voluntary project ran in different groups of adults （healthy, depressed, schizophrenic, and clients with anxiety disorders）. The study is based on analysis of personal counseling experience, where literature was used as a tool to disclose client＇s personal meanings. During our sessions, clients were observed phenomenologically, and their speach was written down. Reflecting on the qualitative data of transformative learning in language arts, we developed techniques for facilitation and disclosure of personal meanings. Grounded theory was used for data generalization： Personal educational insights and its comparison with other researchers＇ theoretical insights were the basis to develop the methodical system for psychological guidance and counseling and to explain it. We revealed that focus on personally important meanings during discussion after literature reading has influence on the mental state of personality and deepens the interactions with the literature art, so we suggest a spiral model to explain the methodical system of our method. Transformative learning in language arts as a method of guidance and counseling can be understood as spiritual motion by spirale. It has three levels：（1） art level （interaction with the literature）; （2） psychology level （counseling）; and （3） art level （interaction with the same peace of literature as in the beginning of the session, poetic summary of the session）. Levels （1） and （3） mean interaction with literature art, but at the third level, this interaction has new quality, because personality has better perception of Self and more ability to connect personal meanings and literature wisdom. At the first level, we have direction from literature to Personality. At the third level, we have direction from the Self （Speaking from Within） to literature. Disclosure of personally important meanings is a key to self-understanding and poetical thinking; our developed methodical system reduces emotional tension and strengthens interco

Predictors of premature delivery in patients with intrahepatic cholestasis of pregnancy

引用

World Journal of Gastroenterology 2007年第46期13卷 6226-6230页

作者： jurate Kondrackiene Ulrich Beuers Rimantas Zalinkevicius Horst-Dietmar Tauschel Vladas Gintautas Limas Kupcinskas Department of Gastroenterology Kaunas University of MedicineKaunasLithuania Department of Gastroenterology and Hepatology Academic Medical CenterUniversity of AmsterdamAmsterdamThe Netherlands Institute of Endocrinology Kaunas University of MedicineKaunasLithuania Dr.Falk Pharma GmbH FreiburgGermany Department of Obstetrics and Gynecology Kaunas University of MedicineKaunasLithuania

AIM： To evaluate the predictive value of clinical symptoms and biochemical parameters for prematurity in intrahepatic cholestasis of pregnancy （ICP）. METHODS： Sixty symptomatic patients with ICP were included in this retrospective analysis. Preterm delivery was defined as delivery before 37 wk gestation. Predictors of preterm delivery were disclosed by binary multivariate logistic regression analysis. RESULTS： Mean time of delivery was 38.1 ± 1.7 wk. No stillbirths occurred. Premature delivery was observed in eight （13.3%） patients. Total fasting serum bile acids were higher （47.8 ±15.2 vs 41.0 ± 10.0 μmol/L, P 〈 0.05）, and pruritus tended to start earlier （29.0 ± 3.9 vs 31.6 ± 3.3 wk, P = 0.057） in patients with premature delivery when compared to those with term delivery. Binary multivariate logistic regression analysis revealed that early onset of pruritus （OR 1.70, 95% CI 1.23-2.95, P = 0.038） and serum bile acid （OR 2.13, 95% CI 1.13-3.25, P = 0.013） were independent predictors of preterm delivery. CONCLUSION： Early onset of pruritus and high levels of serum bile acids predict preterm delivery in ICP, and define a subgroup of patients at risk for poor neonatal outcome.
