  • Analysis of Lead in Toys

    Important and always current is the analysis of lead in toys for children. Details about the effective sample comminution with FRITSCH Mills. Lead is a toxic heavy metal. Approx. 90 % of the incorporated lead is deposited in the bones and the teeth. Because lead is released very slowly, it will be accumulated over the time in the body. This is dangerous especially for children.  The European ...

  • EDXRF Analysis of Lead, Cadmium, Silver, Copper in Lead-Free Solder Materials

    X-ray fluorescence analysis can be used to quickly and easily analyze samples in solid, powder, and liquid states nondestructively, and is therefore widely used as a screening technique for compliance with the RoHS/ELV directives. A large amount of lead-free solder is used for surface-mount circuit boards. Here we evaluated the sensitivity of analysis of Pb, Cd, Ag, and Cu in lead-free solder ...

  • May spirituality lead to reduced ecological footprint? Conceptual framework and empirical analysis

    Living a happy and satisfied life while staying within ecological limits of Earth is a challenge humanity must face during this century. As spirituality impacts our lives in both material and non-material ways, we may reasonably suppose that spiritual beliefs also have an impact on how one thinks about environmental degradation, how likely individuals will behave in a pro-environmental way and ...

  • Analysis of Whole Blood for Trace Lead (Pb) by Graphite Furnace AAS

    Toxic effects from heavy metals (Pb, As, Se, Cd, Bi, Sn, Tl, and Hg) have been characterized in medical literature for decades. Originally, complex extractions were performed to isolate the poisonous components from the complex biological matrices: blood, serum, urine and tissues. Recently, optical emission and atomic absorption spectroscopy techniques were developed to determine these toxic ...

  • Determination of Trace Elements in Lead for Battery Applications using Atomic Absorption Analysis

    Sample and Standard Preparation procedures for Trace Elements in Lead [1] Preparation of Lead (Pb) Samples: Drill Pb metal to make small pieces. Weigh 2.0 grams of these pieces on a balance. Place the sample in a 400ml Pyrex breaker and add 10ml H2O, 2.5 grams of tartaric acid and 7ml HNO3. Warm on a hot-plate until the sample dissolves. Dilute to 100ml in a volumetric flask with water (H2O). ...

  • Portable lead analyzer to locate source of lead

    OBJECTIVE: To investigate the sources of lead in the environment in children with elevated blood, with the help of a Field Portable X-Ray ...

  • Lead in Christmas Lights

    A recent California proposition led to awareness that lead is a stabilizer in the Polyvinyl Chloride (PVC) jacketing that covers conductors in Christmas lights. The objective of this study is to examine the level of accessible lead in Christmas lights. Following U.S. Environmental Protection Agency (U.S. EPA) Lead Inspectors’ procedures, researchers at Cornell University and in Nebraska conducted ...

  • Use of multi-criteria decision analysis in regulatory alternatives analysis: A case study of lead free solder

    Regulators are implementing new programs that require manufacturers of products containing certain chemicals of concern to identify, evaluate and adopt viable, safer alternatives. Such programs raise the difficult question for policymakers and regulated businesses of which alternatives are “viable” and “safer.” To address that question, these programs use ...

  • Getting the lead out — at the faucet

    You might be surprised at where you’ll find a customer’s lead. Lead is making headlines. First, we should note that the current attention is not due to water, air or soil contamination, but from lead contamination recently found in toys and children’s jewelry made in China. This is very frightening for any parent because of the harm lead can to cause in children. How could this happen? How ...

  • Lead in Soil: Comparison of the Cogent Environmental extraction kits and PDV6000plus analysis (ASV) with inductively coupled plasma optical emission spectrometer (ICPOES) Laboratory Extraction and Analysis

    This study contains data generated by Matrix Environmental when using the PDV6000plus to monitor soils for Lead and subsequent analysis of soil samples by an independent reference laboratory by ICPOES to provide comparison ...

  • Sequential extraction combined with isotopic analysis as a tool for studying lead contamination from mining activity

    Tailings deposits generated from mining activities constitute a potential risk to the environment through leaching of potentially toxic elements hosted by a variety of minerals present in the mine-waste materials. In the present work, in an attempt to study the potential mobility of lead in different type of Pb-Zn ore concentrate residues and its environmental impact, a sequential extraction ...

  • Elaboration of the hydroxyapatite with different precursors and application for the retention of the lead

    Carbonate hydroxyapatite (CHAP) was synthesized from different precursors; synthetic (CaCO3 and Ca(OH)2) and natural (egg shell before and after calcinations at 900°C) under different conditions and characterized by using TG/DTG analysis, X-ray powder diffraction (XRD) method and Fourier transform infrared (FT-IR) spectroscopy techniques. The results of these analyses indicate that the four ...

  • World leading in five thematic areas by 2017

    With its vision for a “water wise world”, the Stockholm International Water Institute (SIWI) recently produced its 2013-2017 strategy, placeing its various programmes and activities within five thematic areas: Climate Change; Transboundary Water Management; Water Governance; Water, Energy and Food Nexus; and Water Economics. In the following two pages, we highlight why we work with ...

  • If one country takes the lead, will the rest follow?

    Though most countries agree that warming must be limited to 2 degrees Celsius to avoid the raft of climate risks, they clash about who should do what to reach this target. This could lead to gridlock in Paris in December and potential failure at the world climate summit COP21.  Researchers have determined what amount of emissions reductions it takes for a major economy to ...
