Biostimulation proved to be the most efficient method in the comparison of in situ soil remediation treatments after a simulated oil spill accident

2016

The use of in situ techniques in soil remediation is still rare in Finland and most other European countries due to the uncertainty of the effectiveness of the techniques especially in cold regions and also due to their potential side effects on the environment. In this study, we compared the biostimulation, chemical oxidation, and natural attenuation treatments in natural conditions and pilot scale during a 16-month experiment. A real fuel spill accident was used as a model for experiment setup and soil contamination. We found that biostimulation significantly decreased the contaminant leachate into the water, including also the non-aqueous phase liquid (NAPL). The total NAPL leachate was …

Influence of environmental pollution with creosote oil or its vapors on biomass and selected physiological groups of microorganisms

2017

Survival of microorganisms in soils from treatment facility and landfill of wooden railway sleepers contaminated with creosote oil as well as in two types of soils with different content of organic carbon, treated with creosote oil vapors, was assessed. Microbiological assays including determination of: the biomass of living microorganisms method and the number of proteolytic, lipolytic and amylolytic microorganisms were carried out under laboratory conditions. Chromatography analysis of the soil extract from railway sleepers treatment facility was performed using GC/MS. The highest biomass and the number of tested microorganisms were determined in soils from wooden railway sleepers landfil…

Derecho y conciencia en Antígona: Una respuesta atemporal a los conflictos de familia

2018

El presente artículo aborda la importancia de la familia en Antígona, de Sófocles. Ante el Decreto de Creonte, por el que se prohibía, bajo pena de muerte, enterrar y llorar a Polinices, su hermana ?Antígona ? no duda en afirmar que por encima de las leyes del Estado está la ley de los dioses y la ley que dicta su conciencia, la que le exige anteponer los lazos familiares al orden público. Un acto de desobediencia civil que le conducirá a muerte.

Psychometric properties of the Haitian Creole version of the Resilience Scale with a sample of adult survivors of the 2010 earthquake

2015

Abstract Background Resilience is defined as the ability of people to cope with disasters and significant life adversities. The present paper aims to investigate the underlying structure of the Creole version of the Resilience Scale and its psychometric properties using a sample of adult survivors of the 2010 earthquake. Methods A parallel analysis was conducted to determine the number of factors to extract and confirmatory factor analysis was performed using a sample of 1355 adult survivors of the 2010 earthquake from people of specific places where earthquake occurred with an average age of 31.57 (SD = 14.42). All participants completed the Creole version of Resilience Scale (RS), the Imp…

Estudio de los factores ambientales que afectan a la conducta de actividad física en niños y niñas en edad preescolar

2017

Introducción: La actividad física es una conducta de salud que conlleva múltiples beneficios para la población. En niños y niñas de preescolar, la realización de actividad física conlleva una mejora de la adiposidad corporal, salud ósea, desarrollo de habilidades motoras, salud psicosocial, desarrollo cognitivo y aspectos de la salud cardiometabólica. La realización de dicha actividad va a depender de varios factores, entre los que se encuentran factores ambientales, así como el tiempo en el que pasan los niños y niñas en el contexto escolar. Objetivo general: Conocer y analizar los factores, sobre todo ambientales, que influyen en la conducta de actividad física de los niños y niñas en eda…

Responses of microbial activity and decomposer organisms to contamination in microcosms containing coniferous forest soil.

2002

Soil respiration from microcosms contaminated with pentachlorophenol, 2-ethanolhexanoate, creosote, CuSO4, and benomyl was measured in order to evaluate usefulness of soil microcosms and microbial respiration rate monitoring as a toxicity test in soils with high organic matter content. Coniferous forest soil and its organisms were used as test objects. In addition, how a short-term low temperature period including frost affects respiration dynamics in stressed soils was studied, i.e., whether contaminants reduce resistance of the community to other (also natural) stresses. In addition, at the end of the experiment, effects of contaminants on faunal and microbial community structures were an…

Llano Zapata, a creole of Spain apologist: exchange-critical apologetic about the Spanish colonization in the mid-eighteenth century

2012

espanolLa colonizacion espanola en America ha constituido, desde el primer momento, tema de polemica historiografica. Y no dejo de serlo en el siglo XVIII. Pues bien, a mediados de la centuria, antes e las vehementes apologias del reinado de Carlos III, encontramos la defensa de la colonizacion espanola por parte de un criollo, Llano Zapata, en un vivo dialogo epistolar con el erudito Gregorio Mayans. EnglishThe Spanish colonization in America has been, from the first moment, a theme of historiographic controversy. And it was on like that during the 18th Century. That�s why, in the middle of the Century, before the vehement apologies in the reign of Carlos III, we can find the defense of th…

The toxicity and concentrations of PAHs in creosote-contaminated lake sediment

1999

Sediment samplers, divided into three layers (0 – 10, 10 – 20 and 20 – 30 cm), were collected from 16 sites in Lake Jamsanvesi, Central Finland. The acute toxicity of pore waters and elutriates (sediment + water 1:4 v/v) were studied by bioluminescence inhibition test and by immobilisation of water fleas (Daphnia magna Straus). Concentrations of polycyclic aromatic hydrocarbons (PAHs) in sediments and elutriates were measured by gas chromatography using flame ionization detection (GC/FID). The highest total PAH concentration was 3.3 mg/g dry weight in the sediment and up to 1.7 mg/l in the elutriate of the uppermost (0 – 10 cm) layer, also being the most toxic to photoluminencent bacteria, …

Assessment of bioavailability and effects of chemicals due to remediation actions with caging mussels (Anodonta anatina) at a creosote-contaminated l…

2002

A study was conducted at Lake Jämsänvesi in Central Finland, to identify the potential ecotoxicological risks of the remediation operation of a creosote-/PAH-contaminated lake sediment, made by capping during the years 1998-1999. Mussels (Anodonta anatina) were deployed to the lake at the same time as the remediation operation was started in November 1998. The contaminated area (0.5 ha) was covered by a filter geotextile (polypropylene), gravel and sand (1-1.5m) which were spread out on the ice and let to sink onto the bottom of the lake when the ice melted in May 1999. The possible impacts of capping to the adjacent environment were assessed from mussels exposed and particulate material se…
