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. We hope you enjoy this issue, and be sure to visit to view our complete selection of native and isotopically labeled standards!

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. The increased usage of pyrethroids for agricultural and non-agricultural applications has led to the need for increased testing in environmental and exposure studies, especially in water testing due to known toxicity to fish and other aquatic organisms. The United States Environmental Protection Agency (EPA) is currently reevaluating a total of 23 pyrethroids and pyrethrins for risks to human health and the environment.  Read more...

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. Most recently, BPA has also been associated with causing dysfunction of neutrophils at high doses, potentially leading to immunodeficiency disorders.1 Most human exposure is a direct result of food and beverage consumption, as BPA has been used as a major component in plastics used to manufacture food and beverage containers. Read more...

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. Recently however, the UK has approved a 2022 emergency use authorization of thiamethoxam to treat sugar beet seed to protect the crop from yellow virus carried by aphids. Since the discontinuation of use of thiamethoxam in 2018, yellow virus has been problematic, with a 25% crop loss in 2020.1 Alternate control measures have not been successful at controlling the virus.  Read more...
