  • 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 ...
