  • New Field Test for Lead (Pb2+) in Soil

    Field tests for the detection of lead in soil are not frequently accepted, since the tests are rather cumbersome or not reliable for screening determinations. Recently, we developed the LEADQuick field test kit for the detection of lead in water with 3 #22;g/L sensitivity. This test is further modifiedto detect lead in soil with a sensitivity 0.03 #22;g. We developed an extraction protocol using ...

  • Lead in Paint and Soil in Karnataka and Gujarat, India

    Blood lead surveys in several areas of India have found very high percentages of children with elevated blood lead levels. Fifty-three percent of children under 12 years of age in a sevencity screening had blood lead levels equal to or greater than 10 μg/dL, the level currently considered elevated by the U.S.  Centers for Disease Control and Prevention (CDC). A number of these surveys ...

  • Get the Lead Out - Standards Aid in RoHS Compliance

    RoHS, the seminal European sustainability directive, and others like it challenge manufacturers to eliminate hazardous substances in their products. With RoHS compliance deadlines ongoing through at least the next five years, and more to come from other regions and nations, ASTM Committee F40 is helping companies with testing standards and other resources. The recent introduction of the new Apple ...

  • 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 ...
