Metallic environmental mops
Date: Nov 15, 2009
Author: David Bradley
Inductively coupled plasma spectroscopy and mass spectrometry revealed that natural metal chelators, so-called siderophores, which are produced by bacteria and plants, make much better absorbers of cadmium, and potentially other toxic metals, than synthetic EDTA, and so could improve the efficiency of phytoremediatioon systems.

Extracting the dental lead
Date: Sep 15, 2009
Author: David Bradley
Lead contamination in the black paper used to mask dental X-ray paper has been determined for the first time using AAS. The worrying results suggest that the used material represents an environmental waste problem requiring pre-treatment before disposal.
