Tracing boron: Essential safety levels
Date: Nov 15, 2011
Author: David Bradley
Boron is an essential trace element in many living things but as yet we do not know what the normal levels of this substance are in humans. A study in Chile, where natural boron levels are relatively high, measured exposure levels of boron in drinking water and urine of volunteers using inductively coupled plasma spectroscopy (ICP-OES).

Journal Highlight: Hair lead levels to evaluate the subclinical impact of lead on growth in Sardinian children (Italy)
Date: Oct 31, 2011
Author:
A study of the relationship between lead levels in children's hair measured by ICP-AES, ICP-AAS and ICPMS and their height, sitting height, and estimated leg length supports the use of lead as a biomarker to assess the impact of subclinical lead on the physical growth of children.

Journal Highlight: Cannabis profiling based on its elemental composition - Is it possible?
Date: Oct 3, 2011
Author:
The elemental composition of 85 cannabis samples was established using GF AAS and ICP OES methods and a classification model was developed that correctly classified selected samples of known origin before being applied to siezed samples for origin assessment.

Heavy metal: Simultaneous detection, extraction
Date: Sep 15, 2011
Author: David Bradley
A novel approach to detection of toxic metal ions based on amino-functionalized gold nanoparticles not only provides analytical data on contaminated aqueous samples, but at the same time allows the ions to be extracted from the sample. Atomic absorption spectroscopy verifies the detection of heavy metals down to picomolar concentrations.

Snap happy: Digital camera to oust atomic spectrometer?
Date: Aug 15, 2011
Author: David Bradley
Researchers in Spain are hoping that a standard digital camera is the perfect alternative to expensive and sophisticated laboratory instrumentation for some analytical applications. They have demonstrated how it can be used to determined potassium and magnesium concentrations and water hardness and validated the results against conventional AAS measurements.
