Aquatic aluminium all-clear
Date: May 15, 2010
Author: David Bradley
Inductively coupled plasma atomic emission spectroscopy was used to track the path of an aluminium contaminant in water as it travels through the food chain. The study indicates that the toxic metal accumulates only in the inedible parts of shellfish.

Heavy metals and hardened arteries
Date: Apr 15, 2010
Author: David Bradley
The way in which arterial plaques form, atherogenesis, is not yet completely understood despite a significant number of research studies in this area. Now, a study using rabbits on a high-fat diet (HFD) has investigated the effects of changes in the concentrations of trace elements., iron (Fe), copper (Cu) and zinc (Zn), in several tissues using atomic absorption spectroscopy.
