  • Two Detector Solution to Analyzing Sulfur

    Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful in many other industries; therefore, detection of sulfur compounds in ...

  • An integrated framework to serve the bottom of pyramid

    The objective of the present study was threefold: 1) to critically analyse the mutual value created by enterprises operating in India to serve the BOP; 2) to analyse the constraints faced by these enterprises and strategies adopted by them overcome the constraints; 3) to understand the business model being adopted by the enterprises serving BOP. In order to achieve the above objectives data was ...

  • Accumulation of heavy metals in the bottom sediments of the Irkutsk Reservoir

    The chemical composition of the bottom sediment, and more particularly the heavy metals content, reflects human developments and impacts on the catchment and reservoir's natural environment. The bottom sediments of the reservoir retained by the Irkutsk Dam have been analysed. The reservoir is mainly supplied by water from Lake Baikal. The following amounts of heavy metals have been found in the ...

  • Sampling moisture in the soil profile

    Patterns of water replenishment and use give rise to large spatial variations in soil moisture over the depth of the soil profile. Accurate measurements of profile water content are therefore the basis of any water budget study. When monitored accurately, profile measurements show the rates of water use, amounts of deep percolation, and amounts of water stored for plant use.Experimental ...

  • Critical reflections of the triple bottom line as a schema for reporting: a practitioners' view

    Triple bottom line (TBL) reporting has become a way of life in terms of non–financial reporting at major corporations. However, its utility in terms of value–add for these corporations seems to be a mystery at present. This paper aims to look at how corporations use the TBL as a framework for reporting and what limitations key members of these corporations see with the TBL approach. In ...

  • Distribution of mercury in the water and bottom sediment of the J.A. Alzate Dam, Mexico

    In this paper, mercury concentration in the soluble, particulate and total fractions of water and in the sediment from the Jose Antonio Alzate Dam in the State of Mexico was evaluated using neutron activation analysis in order to determine the bioavailability and distribution of this metal. Sampling was carried out on three separate seasons – cold dry season, hot dry season and rainy season – ...

  • Corporate social responsibility and the challenge of triple bottom line integration: insights from the Lebanese context

    The notion of sustainability has been evolving and is increasingly understood to encompass considerations of economic viability, as well as environmental sustainability and social responsibility. This paper examines how linking these three legs of sustainability remains a challenge and explores empirically the performance of a sample of Lebanese organisations in the three strands of ...

  • Sustainable sampling of native bromeliads for environmental monitoring

    By analysing the leaves of bromeliads, the availability of chemical elements in the atmosphere can be assessed. However, sampling steps affect the reliability of using such plants for environmental quality studies. This paper describes a novel and sustainable sampling methodology for conservation units, in which small discs (6 mm diameter) of bromeliad leaves could be taken without removing ...

  • Coastal Resources Exploitation can Mask Bottom–up Mesoscale Regulation of Intertidal Populations

    We describe the spatial distribution patterns of rocky intertidal Patella spp. limpets (heavily collected by shellfishers) and top-shell snails belonging to the genus Osilinus (comparatively slightly harvested) through a multiscaled sampling design spanning five orders of magnitude of spatial variability (from 10s of m to 100s of km) throughout the Canarian Archipelago (eastern Atlantic); where ...

  • Low Flow Groundwater Sampling Using RotaPump Inertial Lift Pump

    This article tells you how to perform low flow groundwater sampling using a portable, surface-mounted pump with no decontamination required before each use and  no chance of cross contamination between wells. An inertial lift pump moves a dedicated (stored in the well) pumping tube rapidly up and down.  A one-way valve on the bottom admits water on the down stroke and ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • Methods to assess carbonaceous aerosol sampling artifacts for IMPROVE and other long-term networks

    Volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) adsorb to quartz fiber filters during fine and coarse particulate matter (PM2.5 and PM10, respectively) sampling for thermal/optical carbon analysis that measures organic carbon (OC) and elemental carbon (EC). Particulate SVOCs can evaporate after collection, with a small portion adsorbed within the filter. Adsorbed ...

  • Lead (Pb) in Workplace Air by Niton 700 Series Field Portable X-Ray Fluorescence (XRF) Analyzer

    Procedure: Air samples are collected by drawing workplace air, using personal sampling pumps, through 37-mm mixed cellulose ester (MCE) filters mounted in polystyrene cassettes. Samples are prepared for XRF analyses by transferring each filter, along with the support pad, to a special air filter sample holder, specifically designed for a Niton XRF analyzer. Three separate 60-second readings are ...

  • Characterisation and settling of solids in an open, grassed, stormwater sewer network detention basin

    ABSTRACTThe objective of the study is to develop new operational management practices for detention tanks during rainfall events in order to limit flooding risk and, at the same time, to reduce pollutant discharges by optimising the settling process. This paper presents the results of the characterisation of settled particles in an open stormwater detention basin with grassed banks and bottom, ...

  • Evaluation of novel hollow fibre membranes for NOM removal by advanced membrane autopsy

    A full-scale inside out hollow fibre membrane module was operated in a pilot-scale water treatment plant in Sweden for a period of 12 months from August 2013 to July 2014. Liquid chromatography– organic carbon detection (LC-OCD) chromatogram indicated the membranes could effectively remove 86% of dissolved organic carbon and 92% of humic substances from the feedwater. Routine cleaning-in-place ...
