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 ...

Soil samples collected in housing areas with potential lead contamination generally are analyzed with flame atomic absorption spectrometry (FAAS) or other laboratory methods. Previous work indicates that field-portable X-ray fluorescence (XRF) analysis is capable of detecting soil lead levels comparable to those detected by FAAS in samples sieved to less than 125 μm in a laboratory. A ...

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 ...

The Republic of Zambia is rich in mineral resources, such as zinc (Zn) and lead (Pb), and mining is a key industry in Zambia. A previous study of Pb pollution in Kabwe, one of the main mining areas, found that soil was contaminated with high levels of toxic metals over a substantial area. In the present study, the authors focus on toxic metal pollution in cattle, one of the most important ...

I’m an avid gardener. I revel in spending an afternoon under the warmth of the sun getting my hands into the soil, re-planting flowers, nurturing the unhealthy and staking blossoms. It is a time when good ideas seep into my mind and badideas creep out. It is my learning laboratory. One of the many things that my garden has taught me is that the plants fallinto three growing categories: those that ...

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 ...

To find sources of leading safety indicators, we need to look at the base of the Heinrich Safety Pyramid. Leading safety indicators are derived from safety incidents that did not result in injury. These can include everything from job safety observations and attendance at safety meetings to unsafe acts and near misses. These are different than lagging indicators, which are statistics that result ...
