Butts are no joke: FAAS, the evidence

Date: Jul 15, 2016

Author: David Bradley

Graphite furnace atomic absorption spectrophotometry (FAAS) reveals that toxic metals from cigarette butts could be an important source of pollution thanks to the millions that are discarded by smokers and end up on shorelines and in the oceans.

Fruiting bodies: Full metal mushroom

Date: Apr 15, 2016

Author: David Bradley

It is assumed that edible mushrooms are full of natural goodness, but a new inductively coupled plasma atomic emission spectroscopy (ICP-OES) and cold vapour atomic absorption spectrometry (CV-AAS) study reveals that while at least one species may be rich in essential trace metals it can also contain toxic elements such as mercury.
