CPSC Bans a Large Class of Commonly-Used Flame Retardants
The Consumer Product Safety Commission (CPSC) voted on September 20, 2017 to ban the use of any non-polymeric organohalogen flame retardants in a variety of products. This decision came as a response to a petition filed in 2015 by a consortium of non-governmental agencies, which argued that organohalogen flame retardants should be addressed as a single class and banned due to their widespread human exposure and potential human health impacts.
New Exponent US Chemical Regulation and Food Safety Offering: Waiver from the (OCSPP 870.1200) Testing Requirement for Acute Dermal Toxicity Testing for Formulated Products
Exponent is now offering waiver support services for clients that are subject to from the OCSPP 870.1200 testing requirements for acute dermal toxicity testing of formulated pesticide products.

Conflicting Views on the Potential Carcinogenicity of Glyphosate: How Did We Get Here and What Should We Do
The advent of the internet and the information age has allowed the public to become keenly aware of the perceived dangers to health from polluted air and water, pesticide residues in foods, and global warming. Much of the available information on the worldwide web is not vetted, resulting in opinions that are based on anecdotal, emotional and alarming misinformation that runs counter to well-established, science-based medical knowledge.
How Well Can Carcinogenicity Be Predicted By High Throughput “Characteristics Of Carcinogens” Mechanistic Data?
The International Agency for Research on Cancer (IARC) has begun using ToxCast/Tox21 data in an effort to represent key characteristics of carcinogens to organize and weigh mechanistic evidence in cancer hazard determinations. To determine how well ToxCast/Tox21 data can explicitly predict cancer hazard, this approach was evaluated with statistical analyses and machine learning prediction algorithms.
