The Standard - December 2021

Three neonicotinoid pesticides – clothianidin, imidacloprid, and thiamethoxam – have been of increased interest in both the United States and Europe for their potential adverse effects. Neonicotinoids have previously been speculated as a possible cause of colony collapse disorder (CCD) in honeybees, and in August 2021 the United States Environmental Protection Agency (US EPA) released draft evaluations stating the likelihood that clothianidin, imidacloprid, and thiamethoxam can adversely affect more than 1,000 endangered plants and animals.¹

Since the initial reports of nitrosamine contamination in blood pressure medicines in 2018, screening lists have become more commonplace for nitrosamine levels in medications and other matrices. CIL has offered stable isotope-labeled and native individual nitrosamine standards for many years and has recently developed multi-component mixtures to support comprehensive testing.

CIL’s environmental product line is regularly expanding and updating to meet customer needs, with a current inventory of approximately 3,700 different products, including options as single-component formulated standards as well as multi-component mixtures. While CIL started out making strictly "environmental” contaminant standards, the scope of the offerings has expanded to include products for food, water, and exposure analysis. Of the 3,700 products in the portfolio, it might be interesting to note that some 1,100 are native or “unlabeled” products.
