Short-chain per- and polyfluoroalkyl substances (PFAS) are increasing in the Canadian Arctic environment, with the most rapid increases occurring post-2000, according to a recent study in Geophysical Research Letters (April 2020). For example, trifluoracetic acid (TFA) in the Devon Ice Cap increased ~10-fold from 1.4 μg/m2 per year during 1977–1989 to 10.3 μg/m2 per year during 2001–2014. The authors of the study suggest that the increased short-chain PFAS concentrations post-2000 were from new chlorofluorocarbon (CFC) replacement chemicals produced as a result of the 1987 Montreal Protocol treaty. One of the paper’s lead authors, Professor Cora Young of York University in Toronto, Ontario, discussed the study findings during the inaugural episode of my new video podcast, “PFAS fireside chats with Craig Butt.
The completion of the human genome project in 2003 opened the door to unprecedented insight into the human body through its DNA code. We now know that our genome encodes our proteins, that our proteins are the molecular machinery of certain functions that take place in our cells and that the end products of these functions are our metabolites.
When Pacific salmon start to die in large numbers, with no identified cause, people take notice. This concern stems not only from the possibility of an environmental issue that could additionally affect human health, but also, in this case, from the cultural and economic importance of Pacific salmon.
Cannabis strains not only have different effects, but also serve different purposes. In the mainstream world, cannabis is grouped into 3 distinct strains: Indica, Sativa and hybrid. Indica strains are of Hindu Kush Mountain origins, and they are high in tetrahydrocannabinol (THC) content and dense cannabidiol (CBD). They are often believed to be relaxing and are used in pain management. Sativa strains, on the other hand, have a more energizing effect, and hybrid strains are a combination of Indica and Sativa.1

Swimming is a favorite summer pastime for many, and swimming pools are frequent destination for this activity. Of course, keeping the water in swimming pools clean means the use of disinfectants, and researchers at the University of Alberta in Canada published some insightful findings in this area. Wei Wang and coworkers in the university’s Division of Analytical and Environmental Toxicology conducted a study using the SCIEX Triple Quad™ LC-MS/MS System to quantify the presence of halobenzoquinones (HBQs), a class of disinfection byproducts (DBPs) of health relevance, in swimming pools.
The Science Explorer interviews Neil Walsh from SCIEX to discuss the significant application areas of the Echo® MS System and what makes this system so attractive to biopharmaceutical laboratories.
Intabio acquisition expands SCIEX portfolio of impactful solutions to accelerate biotherapeutic development
Due to the nature of their production, biotherapeutics are difficult to manufacture. Growth conditions, purification protocols and formulation requirements can introduce unintended modifications into the protein structure that may affect its efficacy and safety. Imaged capillary isoelectric focusing (iCIEF) provides a critical measure of quality throughout the development and manufacturing of biotherapeutics by offering rapid, robust and high-resolution charge variant analysis.
A recent webinar from SCIEX and New Food, presented by Jianru Stahl-Zeng of SCIEX, outlined some of the capabilities of the new SCIEX Triple Quad™ 7500 LC-MS/MS System – QTRAP® Ready. In particular, it highlighted the ability of the SCIEX 7500 System to accurately quantify 700 pesticide residues across 10 different food matrices at ultra-low trace levels. During the webinar, attendees posed various questions. Here, we share the top 5 of these questions, along with their answers.
As the per- and polyfluoroalkyl substances (PFAS) regulatory landscape evolves in the US and across the globe, the interest in PFAS continues to grow. Drinking water and food packaging are under particular scrutiny, and monitoring programs and requirements will continue to expand to include an increasing variety of sample types and PFAS compounds.
