US EPA Withdraws Interim Registration Review Decision for Glyphosate

Effective September 23, 2022, the United States Environmental Protection Agency (US EPA) announced its withdrawal of the interim registration review decision for the herbicide glyphosate. This update allows products containing glyphosate to remain on the market as well as continued use according to the product labels and application instructions.1 The US EPA is currently conducting a registration review of glyphosate, which is required every 15 years, and expects to complete the review by 2026.

CIL – The World’s Leading Producer of Stable Isotopes

Did you know CIL separates and produces its own labeled compounds with carbon-13 (13C), oxygen-18 (18O), and deuterium (D) isotopes? In 1990, CIL constructed the world’s largest 13C isotope-separation plant, CIL Isotope Separations, LLC (CIS) in Xenia, OH, USA. In 2000, CIL responded to the worldwide shortage of 18O water by constructing, at that time, the world’s largest 18O isotope-separation facility at CIS, which remains one of the largest 18O isotope-separation facilities to date. CIS also houses the only large-capacity nongovernmental D2O (deuterium oxide) enrichment columns. Since the initial construction, CIS has grown to 48 acres and there have been four past expansions of 13C production. With ever-growing needs for isotopically labeled compounds, CIL recently invested in a massive new expansion at CIS which is expected to be completed in 2024 and will significantly increase 13C production by building a separate cryogenic distillation facility for carbon monoxide.

PFAS Detected in Pet Food Packaging
Per- and polyfluoroalkyl substances (PFAS) have notably been detected in water sources, with more recent focus shifting to other PFAS-contaminated products including cookware, cosmetics, and food packaging. PFAS exposure impacts both humans and animals, though most studies have focused on human exposure. A recent study conducted by the Environmental Working Group (EWG) has detected seven PFAS compounds in some pet food bags used by several brands.1 The seven PFAS detected included perfluoropropanoic acid (PFPrA), perfluorobutyric acid (PFBA), perfluoropentanoic acid (PFPeA), perfluorohexanoic acid (PFHxA), perfluoroheptanoic acid (PFHpA), 6:2 fluorotelomer carboxylic acid (6:2 FTCA), and 6:2 fluorotelomer phosphate diester (6:2 diPAP). The study did not test the pet food to confirm if the PFAS migrated from the packaging into the food.
