  • Increased demand for XRF analyser hire

    Steve Drake, NDT Market Manager at Ashtead Technology believes that XRF is one of the most important technologies in the company’s fleet of NDT and environmental testing instruments. “With a small amount of training, almost anyone can implement detailed inspections in a wide variety of applications, and with most instruments being lightweight and robust, XRF analysers are among the ...

  • Purge Trap for GC Analyses of Volatile Aromatic (BTEX) Compounds in Soils and Sediments

    The BTEXTRAP purge trap was designed specifically for monitoring benzene, toluene, ethylbenzene, and the xylene isomers (BTEX compounds).  The trap allows large amounts of methanol (used in the US EPA Method 5030 procedure for preparing soil and sediment samples) to pass through the adsorbent beds while retaining the analytes of interest.  In evaluations of trap performance, relative ...

  • Hired metals analyser ensures remediation success

    Cognition Land and Water Ltd, a UK based remediation specialist, has hired a portable XRF metals analyser to improve the speed of remediation work at a project in London’s Kentish Town. The project had a major impact on local residents so timescales were extremely tight but Cognition’s Charlie Jarvis says “It would not have been possible to meet the deadline without the use of ...

  • Transcriptional profiling of the soil invertebrate (Folsomia candida) in pentachlorophenol contaminated soil

    Pentachlorophenol (PCP) as a widely used pesticide is also considered to be an endocrine disruptor. Molecular effects of chemicals with endocrine disrupting potential on soil invertebrates are largely unknown. In this study we explored the transcriptional expression changes of collembola (Folsomia candida) in response to PCP contamination. A total of 92 genes were significantly differentially ...

  • Fighting soil contamination with XRF

    Soil contamination Complying with new environmental regulations is a fast growing concern for companies and local officials tasked with ensuring that industries reduce pollution and clean up after themselves. It’s a particularly challenging issue when it comes to soil contamination It’s not always easy to detect as it silently contaminates crops and the ground water supply. XRF ...

  • Soil geography and geostatistics

    Geostatistics, which can be defined as the tools for studying and predicting the spatial structure of georeferenced variables, have been mainly used in soil science during the past two decades. Since now, hundreds of geostatistical papers have been published on soil science issues. The use of geostatistical tools in soil science is diverse and extensive. It can be for studying and predicting soil ...

  • Holistic approach to biodiversity and bioindication in soil

    After the Rio Conference in 1992, Biodiversity became synonymous with protecting the environment.Bioindication has emerged as useful process for environmental evaluation particularly of the soil, whichis a complex entity able to perform a multitude of key functions, vital for life, such as breathing,assimilating nutrients like carbon and nitrogen, transforming and mineralizing organic materials ...

  • Soil and groundwater assessment, south-east England

    Project Remediation Strategies were appointed to undertake a soil and groundwater assessment to assist a client in understanding the potential environmental liabilities associated with the shallow soils beneath part of the site.  The client was undertaking a phased renewal of the site tank farm areas, which required the excavation and replacement of shallow soils to allow for new ...

  • Analysing the sensitivity behaviour of two hydrology models

    Recently, the New Morris Method has been presented as an effective sensitivity analysis tool for mathematical models. The New Morris Method estimates the sensitivity of an output parameter to a given set of input parameters (first-order effects) and the extent these parameters interact with each other (second-order effects). This method requires the specification of two parameters (runs and ...

  • Cleanup criteria for radionuclides in US surface soil

    The maximum concentrations of individual contaminants that will be allowed to remain in the environment after cleanup are developed on a case-by-case basis and may depend on site-specific risk analyses as well as stakeholder concerns. A database of cleanup criteria has been established from site-specific agreements at US Department of Energy (DOE) remediation sites and was used to analyse the ...

  • Warming and drought alter soil phosphatase activity and soil P availability in a Mediterranean shrubland

    Abstract  We conducted a field experiment simulating the warming and drought in a Mediterranean shrubland dominated by Erica multiflora and Globularia alypum with the aim to simulate the next future climate conditions predicted by the IPCC and ecophysiological models. As P is frequently a limiting nutrient in Mediterranean ecosystems, we investigated the drought and warming effects on soil ...

  • An investigation and remediation of TNT contaminated soils.

    An investigation and remediation of TNT contaminated soils and wastes was conducted at the Apache Powder Superfund Site in Cochise County, Arizona during 1999 and 2000. TNT contamination was most likely the result of salvage operations of World War I munitions. Characterized by a steep hillside and arroyo cutting through the wastes, the site offered challenges of stability, access, health and ...

  • Ultrapure Water for Determination of Toxic Elements in Environmental Analyses

    Abstract In this paper the importance of reagent water quality for toxic element environmental analyses is discussed, and the suitability of fresh ultrapure water produced using Merck water purification systems for ICP-OES and ICP-MS trace element analyses in environmental laboratories is demonstrated. Key words or phrases Trace elements, metals, toxic ...

  • Comparison of linear and non–linear, space frame–raft–soil interaction analyses, by using finite element method

    The objective of the present study is to estimate the realistic displacements and force quantities in the structural members, accounting for their three dimensional behaviour and non–linear constitutive relations of soil. This demands usage of proper constitutive model for soil and its numerical model, which is validated experimentally. A program has been developed in the present work to compare ...

  • Bioremediation of ground water by treatment of soil at source with Vaporremed

    A heating oil company during servicing of a home in PA released almost 150 gallons of heating oil that seeped into the basement and below. Ground water was shallow and PA DEP wanted to ensure that the contamination did not pollute the water. The environment company overlooking the cleanup decided to use VaporRemed to reduce the fumes. In three weeks time the level of contamination of the soil and ...

  • Tungsten effects on microbial community structure and activity in a soil

    Tungsten, once deposited onto a soil as a result of private, industrial, and military activities, may persist as tungstate anion or, via polymerization, as a variety of poly-tungstate species, each with varying solubility and soil sorption characteristics. In this study, the impact of weathered tungsten on a soil microbial community was measured. Fatty acid analyses indicated that weathered ...

  • Analyzing sulfur in soil and sediment with handheld XRF

    Background Sulfur creates more than nasty odors. Exposure to low levels (0-10ppm) of hydrogen sulfide (H2S) causes irritation of eyes, nose, and throat; higher levels can cause headaches, dizziness, nausea and vomiting, coughing, and breathing difficulty. H2S and numerous other odor-causing compounds are generated as a result of organic material decomposition. In the case of the Muddy River in ...

  • Heavy metal pollution of soils along North Shuna-Aqaba Highway, Jordan

    Attention to heavy metal contamination associated with highways or motorways has risen in the last decades because of the associated health hazards and risks. The present study analysed the metal content in soil samples of one of the main highways along the western part of the Jordanian border, the North Shuna–Dead Sea–Aqaba Highway. The metals analysed were Pb, Zn, Cd, Co and Ni. In the samples ...
