Webinar: Ultrashort-chain PFAS: the global threat of trifluoroacetic acid
by Sarah Howard on February 11, 2025 at 4:41 pm
This Feb. 19, 2025 webinar features Dr. Hans Peter Arp discussing TFA, a degradation product of many refrigerants and a widespread contaminant in the environment.

Natural antioxidants in food may help reduce microplastics' reproductive harm
by Katherine McMahon,Sarah Howard on February 13, 2025 at 7:14 pm
According to a recent review published in Journal of Pharmaceutical Analysis, anthocyanins - a plant compound responsible for the vibrant colors in fruits and flowers - may counteract some of the harmful reproductive impacts of micro- and nanoplastic (MNP) exposure. “The accumulation of [MNPs] contaminants across ecosystems raises significant concerns for human health due to their potential dispersion within the human body through respiratory, integumentary, and digestive systems.”

“A once-in-a-lifetime opportunity”: Independent scientists advocate for an effective Global Plastics Treaty
by Sarah Howard,Katherine McMahon on February 18, 2025 at 5:11 pm
Members of the Scientists’ Coalition for an Effective Plastics Treaty, over 70 of whom attended the 5th negotiation session for the UN Plastics Treaty (INC5) in November, argue in a new article published in Cambridge Prisms: Plastics that the treaty must address the full life cycle of plastics and include production reduction targets. “It is critical that the treaty negotiations continue to be informed by independent science, to better ensure that when consensus is reached we have a global approach leading to reduced negative impacts from plastics across their entire life cycle."
Opinion: RFK Jr.’s disinformation is a rallying cry for women in STEM
by Kathryn Rodgers on February 14, 2025 at 2:58 pm
I have never been so motivated and grateful to be a woman in science as while watching Robert F. Kennedy Jr.’s Senate Finance Committee nomination hearing. As an environmental health researcher, I know there is strong evidence that industrial and commercial chemicals are linked to increasing rates of neurodevelopmental disorders, cancer, asthma, and many other chronic diseases. However, RFK Jr. has clearly demonstrated he has very little understanding of public health, science, or women.
