- New Litagion agent profiles for fipronil and liquid crystal monomers
- New blog content: "The past, present, and future of PFAS litigation in the United States" and "Grand experiments revisited"
- Updated Litagion agent and company profiles impacted by newly published peer-reviewed science and newly gathered company information
- Fipronil. Fipronil [CAS No. 120068-37-3] is a broad-spectrum insecticide belonging to the phenylpyrazole family. A wide variety of agricultural and commercial insecticides rely on fipronil to control pests such as moths, grasshoppers, locusts, beetles, crickets, thirps, rootworms, and weevils on field and horticultural crops including corn and turf. Fipronil is also commonly used in flea and tick control products for household pets and consumer ant and roach traps.
- Liquid crystal monomers. Liquid crystal monomers (LCMs) are used in the manufacture of liquid crystal displays (LCDs) found in television sets, computer monitors, tablets, mobile phones, and many other devices with a digital display. Chemical engineers have synthesized and commercialized thousands of distinct LCMs with various chemical structures, but all with the property of transforming between liquid and solid phases as a function of temperature. LCDs shed liquid crystal monomers during use and when disposed and scientists are concerned they might be persistent, bioaccumulative, mobile, and toxic in the environment.
Updated Litagion agent profiles based upon newly published science
All Litagion agent profiles have been updated to reflect the most recently published peer-reviewed science. Notable scientific studies added to CoMeta since the last release include:
- Bisphenol F (BPF). Research employing data from the Swedish Environmental Longitudinal Mother and Child, Asthma and Allergy (SELMA) study reports a positive association between prenatal exposure to BPF and cognition at age 7.
- Imidacloprid and thiamethoxam. A study reports an association between the use of neonicotinoid insecticides and infertility in male farmworkers in Thailand.
In addition, we highlight the following changes to the components of Litagion agent risk resulting from newly published peer-reviewed science:
|Litagion agent||Risk category change||Overall risk change|
|Hydrogen sulfide||Projected science risk changes from Low (green) to Medium-low (yellow)||No change|
|Projected science risk changes from Medium (yellow) to Medium-high (orange)||No change|
