Adriatic Sea. Recently I visited this place and wondered how much #microplastics and #nanoplastics reach this, by eye, presence region. How much of new stuff the system can process in years to come.

Microplastics: Spektrum der Wissenschaft article shows that many headline-grabbing studies likely overestimate concentrations due to methodological limits. Tools for air & water don’t simply work for human tissue. www.spektrum.de/news/mikropl... #microplastics #nanoplastics

Mountaineers, scientists, and glaciers — connected by one invisible pollutant: nanoplastics. Through the GAPS citizen-science network, we now detect nanoplastics deposition on high-altitude glaciers at tens of ng mL⁻¹. First results will be presented at #EGU26 General Assembly. #GAPS #Nanoplastics

Plastics or lipids? Our new paper is out in Nature Medicine! Do we really have grams of plastic in our brains? Not really — Py-GC-MS signals can mimic lipids. The “plastic” might just be the obesity effect — a fatter brain, not a plastic one. www.nature.com/articles/s41... #Microplastics

Let’s address some structural issues in plastic research: A) A large share of #microplastics & #nanoplastics papers are reviews, not primary data (doi.org/10.1016/j.en...) B) Some highly cited, widely publicised studies have critical flaws (e.g., missing proper blanks): doi.org/10.1073/pnas...

Scientists don't have time to ask themselves hard questions! The brain #microplastic paper is a joke: Fat makes false positive PE - see missing high m/z ions in PyGCMS. The brain has ~60% fat, and the liver has ~5%, so that is why there are ~10x more "plastics" in the brain. doi.org/10.1038/s415...
