Pesky pesticides
Researchers from the University of Toledo, Ohio, US, have designed a new pesticide exposure tool that measures pesticides in human plasma to protect inexperienced cannabis farmers. Using biocompatible solid-phase microextraction paired with liquid chromatography-tandem mass spectrometry (aka bio-SPME-LC-MS/MS – a bit of a mouthful, I know!), this method can detect 79 pesticide residues in human blood plasma at “ultra-trace” levels. In the press release, one of the authors added, “Assessing pesticide exposure quickly and thoroughly is crucial for the health and safety of workers and their families, to correct malpractices in pesticide storage and application, and to prevent further exposure.”
Hemp genetics
The Institute for Advanced Learning and Research in Danville, Virginia, US, has received a US$600,000 grant to study the regulation of the genes responsible for cannabinoid biosynthesis in industrial hemp. According to the researchers, the work could help support improved selection or modification of hemp plants with particular cannabinoid content, increasing profits (by boosting concentrations of sought after cannabinoids) and reducing risk for farmers (by keeping THC concentrations below 0.3 percent).
