#SETACMaastricht was a blast, on so many levels! Really high quality science and inspirational plenaries collided with great organisation and a super venue with top-notch all veggie catering (and decent coffee!), making for what I heard a few times referred to as "the best SETAC ever".

Calling all #SETACMaastricht goers with an interest in exposure modelling! Come along to our workshop today at 4-5pm in Room 0.2. Everyone welcome. #SETACEurope

Thanks to everyone who came to the UTOPIA training this morning! We had great discussions about how we can use evaluative models for scenario assessment, challenges in parameterization, and how we can adapt for regional/local contexts. #SETACMaastricht #SETACEurope @mattmacleod.bsky.social

We're looking forward to #SETACMaastricht next week. UKCEH scientists will highlight research on topics including microplastics, PFAS and metal pollution. Dr Michael Pocock will also give a plenary talk on the benefits and impacts of #CitizenScience. See more: www.ceh.ac.uk/news-and-med... 🧪

Very excited to be attending my 10th #SETACEurope conference next week! It's going to be a busy time, with lots of exciting exposure modelling-related stuff going on 👇 #SETACMaastricht @ukceh.bsky.social

Great to be part of the team contributing to this new book on #microplastics and #nanoplastics. I helped with two chapters alongside super co-authors @praetorius-a.bsky.social, @mattmacleod.bsky.social, @pradodomercq.bsky.social, Patrizia Schmidt and Wendel Wohlleben.

Hot off the press in @pubs.acs.org Environmental Science & Technology - our new paper investigating relationships between #microplastics and #plasticisers in sediments of the Forth estuary. pubs.acs.org/doi/10.1021/...

Are Microplastic (∼25–1000 μm) and Plasticizer Concentrations Correlated in Sediments of an Urbanized UK Estuary?

An understanding of the relationships between plastics and plasticizers is vital in order to assess their environmental risk. We investigated spatial trends and relationships between microplastics and plasticizers in sediments of an urbanized estuary subject to contemporary and historic sources of contamination (Forth estuary, Scotland, UK). As such, this study represents one of the first to investigate the co-occurrence of emerging plasticizers, phthalates, and microplastics in an estuary system. We determined the concentration of 7 legacy (phthalate) and 3 emerging (adipate, terephthalate, trimellitate) plasticizers and 21 microplastic polymer types. The most abundant microplastics were polyethylene (PE), polypropylene (PP), polyurethane (PU), and poly(vinyl chloride) (PVC). Plasticizers were dominated by diethylhexyl phthalate (DEHP), although emerging plasticizers (e.g., diethylhexyl terephthalate, DEHTP) were frequently detected at low concentrations (mean 7.3 ng g–1 ww). There was strong evidence that concentrations of microplastics and plasticizers were significantly lower in the outer estuary. However, we found no evidence for a spatial relationship between the concentration of microplastics and plasticizers at individual site level. Our results indicate that microplastics in the size range analyzed (∼25–1000 μm) may not be a good predictor of the spatial distribution of plasticizers in estuaries. This could result from release of plasticizers prior to plastic fragmentation and deposition and differences in transport and fate.
