  • A Trace of Arsenic

    The cans of baby formula invaded Brian Jackson’s Dartmouth College lab late in 2010. His team picked up an armful of popular brands at the food co-op in Hanover, N.H. Then another armload. Eventually Jackson had a cabinet full of the brightly labeled canisters. Today, he still keeps a few in his office. Not as clutter — that’s not his style. He just likes to keep his toxicology ...

  • Tracking and tracing: principles and practice

    The meaning of the concepts "tracking" and "tracing" are clarified, trying to avoid overlap and making them a complementary pair. Tracking and tracing systems are classified using eight attributes. Seven applications of tracking and tracing systems are analysed using these attributes. It is seen that most existing tracking and tracing systems are of a relatively simple type, ...

  • Analyses of trace elements on quartz surfaces in sulfidic mine tailings from Kristineberg (Sweden) a few years after remediation

    Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has been applied to determine the elemental composition of the surface layer, as well as of the first interior layer, of quartz grains from the mine tailings from Kristineberg (northern Sweden) in order to determine concentration gradients between these two layers. The quartz grains were collected from the oxidized and ...

  • Speciation of major, minor and trace elements in River Nile mud

    Nile mud sediment samples were collected from the bottom of the main stream of the River Nile at Aswan (Governorate) and ten other sites along the river. The samples were analysed using various acid extraction systems. Atomic absorption spectrophotometry was used for multi-element determination, and chromic acid was used for organic matter determination. Values of 0.08-0.89%, 0.4-8.5 ppm, ...

  • Emissions analyser helps manage power station

    A multiparameter emissions monitor at Thetford power station is being used to demonstrate to the Environment Agency that the plant is performing within the conditions of its environmental permit. However, the data from the analyser, which was supplied by Milton Keynes based Quantitech, also performs a vitally important role in helping to manage the plant. “Individual gas readings are ...

  • The technology-component matrix: a tool for analysing and managing knowledge

    Previous studies have shown that knowledge creation is becoming a core competency, and technology issues have to be incorporated into corporate strategy in a new way. However, there is a lack of an appropriate framework which would allow practitioners to trace the value migration among different types of technology. This paper, by introducing an innovative technology-component matrix, aims to ...

  • Analyze Trace Amounts of Solvents in Water Using Packed Column GC

    Glass or stainless steel columns containing 80/120 Carbopack B/3% SP-1500 packing can be used to analyze water-based samples for ppm to low percentage levels of many organic compounds. This bulletin describes minimum detection limits and maximum capacity of these columns, adsorption and memory effects, and other factors that affect component quantitation. Problems are defined that might arise ...

  • A statistical approach applied to trace metal data from biomonitoring studies

    This work underlines the importance of the statistical procedures necessary for the significant assessment of analytical data of heavy metals derived from marine organisms (biomonitors) collected at five stations in Ustica at the Southern Tyrrhenian Sea. The statistical method described indicates that, where the differences among the averages of Pb, Cu and Zn concentrations in the molluscs of the ...

  • Trace Analysis of PAHs using EPA methods 3541, 3545 and 8100

    The Extraction System B-811 and the Syncore Analyst parallel concentrator from Buchi as well as the Pressurized Solvent Extractor from Applied Separations were evaluated for the pretreatment of samples containing PAHs. Recoveries of extraction and subsequent concentration using acetone-n-hexane (1+1) were 70-95% for 2 ring and 90-100% for less volatile 3-5 ring PAHs. A good precision (95% ...

  • INAA and AAS study of essential trace elements in ayurvedic Indian medicinal plants

    Specific parts (leaves and fruits) of different medicinal plants often used in Indian ayurvedic system were analysed for 18 elements (K, Mn, Na, Fe, Zn, Cu, Co, Br, Sm, Cl, La, Al, Cr, Ca Cd, Ni, Pb and Hg) by employing instrumental neutron activation analysis (INAA) and atomic absorption spectroscopy (AAS) techniques. The samples were irradiated with thermal neutrons in a nuclear reactor and the ...

  • Does organising matter? Tracing connections to environmental impacts in different housing estates

    Much of the research on buildings and the environment is of a technical-economic nature. But so far, this has not led to any great changes in practice. This article brings organising into the research agenda: Does organising matter for the environmental performance of buildings? If so, how? This question is investigated by a comparative analysis based on an empirical approach. Two housing ...

  • Leaves of Lolium multiflorum as indicators of airborne trace element distribution in Central Italy

    Ambient air contains particles, ranging from sub-micrometric aerosols to clearly visible dust and sand grains. Plants during evolution developed the ability to maximise light interception and CO2 assimilation and also the efficiency to collect the airborne pollutants. Therefore, plant tissues have been used as indicators of trace elements air pollution. Lolium multiflorum leaves were used as a ...

  • Fractionation of uranium and other trace elements in soil samples collected in selected regions of the Republic of Kazakhstan

    To determine the specific chemical forms of trace elements and to study of their mobility/availability in soil, samples collected in the Republic of Kazakhstan were analysed using the revised BCR protocol. A study was made with dependence of the mobility of different elements of interest on digestion procedures for collected soil samples and Standard Reference Material. The concentrations of the ...

  • Spatial distribution and sources of dissolved trace metals in surface water of the Wei River, China

    For this study, 34 water samples were collected along the Wei River and its tributaries. Multivariate statistical analyses were employed to interpret the environmental data and to identify the natural and anthropogenic trace metal inputs to the surface waters of the river. Our results revealed that Zn, Se, B, Ba, Fe, Mn, Mo, Ni and V were all detected in the Wei River. Compared to drinking water ...
