Potentially dangerous levels of the methamphetamine analogue, N, ??diethyl?phenylethylamine (N, ? -DEPEA), have been detected in a widely available dietary supplement using ultrahigh-pressure liquid chromatography coupled to mass spectrometry (UHPLC–MS). The supplement, Craze, can be bought in the USA and from on-line retailers. The findings have been published in the journal Drug Testing and Analysis by a team of scientists from Harvard Medical School (Massachusetts, USA), NSF International (Missouri, USA), and the National Institute for Public Health and the Environment Health Protection Center (Bilthoven, The Netherlands).1

Engineered nanoparticles released into the environment may affect the growth of agriculturally important crops, according to a new study published in the journal of Environmental Science and Technology.1 Scientists from The Connecticut Agricultural Experiment Station (Connecticut, USA) investigated the effect of multiwalled carbon nanotubes (MWCNTs) and C60 fullerenes on plant growth. The investigation was part of a larger project funded by the US Department of Agriculture to look at the impact of nanoparticles on agriculture. The team used gas chromatography coupled with mass spectrometry (GC?MS) in this study.
