The Standard – April 2022

Welcome to the April 2022 edition of “The Standard,” CIL’s newsletter for issues related to environmental, food, water, and human exposure testing. In this issue we highlight our new pyrethroid metabolite standards, discuss why Europe proposes a reduction in the use of Bisphenol A, and talk about why the UK has issued an emergency use of thiamethoxam.

New Pyrethroid Metabolite Standards – Now Available!

Pyrethroid insecticides are synthetic analogs of naturally occurring pyrethrins, which are derived from chrysanthemum flowers. Pyrethroids have been gaining popularity for use against a wide range of insects in place of traditionally used organochlorine (OC) and organophosphorus (OP) pesticides.

Europe Proposes Large Reduction in Use of Bisphenol A

Bisphenol A (BPA) is a synthetic chemical that has been used in the manufacture of epoxy resins and polycarbonate plastic. BPA is a known endocrine disruptor and has been linked to causing reproductive and neurological problems.

UK Approves Emergency Use Authorization of Thiamethoxam in Sugar Beets

Outdoor use of three neonicotinoids – clothianidin, imidacloprid, and thiamethoxam – has been prohibited in the United Kingdom (UK) since 2018. Many countries have been limiting use, or banning use, of certain neonicotinoids due to their being associated with contributing to colony collapse disorder (CCD) in honeybees.
