Letter to Science: A global plastic treaty must cap production

In a letter to the journal Science, we argue that capping and phasing out the production of new plastics must be part of a systemic solution to end plastic pollution. The central argument of the short piece is that modeling studies show that all other available solutions will not suffice to achieve zero plastic emissions to nature. As one of my co-authors puts it:

“Even if we recycled better and tried to manage the waste as much as we can, we would still release more than 17 million tons of plastic per year into nature.”

Melanie Bergmann, Alfred-Wegener-Institute, Germany

The letter was published in Science on April 29th, 2022: https://www.science.org/doi/10.1126/science.abq0082

Microplastics and child health in EHP

We just published a commentary on early-life exposures to nano- and microplastics in Environmental Health Perspectives. Great work in an interdisciplinary team lead by Kam Sripada.

Few studies have addressed child-specific sources of exposure, and exposure estimates currently rely on generic assumptions rather than empirical measurements. Furthermore, toxicological research on NMPs has not specifically focused on child health, yet children’s immature defense mechanisms make them particularly vulnerable…

Here is a public summary of what we found and ISCHE and Little Things Matter provide prevention tips for parents/guardians and a short video:

New paper in Nature Reviews

Denise Mitrano and I have done some thinking, discussing and writing on how to make the plastics economy of the future should look like. Sustainability depends on (re)designing materials, products and systems for circularity, safety and retained value. Read more here: https://www.nature.com/articles/s41578-021-00406-9

Toxicity of aged microplastics

We just published a new paper entitled “Incubation in Wastewater Reduces the Multigenerational Effects of Microplastics in Daphnia magna.” This is the last paper of Christoph’s PhD project and part of the work we do in PLAWES.
