Abstract Critical Zone (CZ) scientists have advanced understanding of Earth's surface through process‐based research that quantifies water, energy, and mass fluxes in predominantly undisturbed systems. However, the CZ is being increasingly altered by humans climate land use change. Expanding scope science to include both human‐ non‐human controls on important for anthropogenic impacts processes ecosystem services. Here, we share perspectives from U.S.‐based, early career centered around broadening focus societally relevant a transdisciplinary framework. We call increased training methods collaboration opportunities across disciplines with stakeholders foster scientific community values alongside physical science. build existing frameworks highlighting need institutional support educate graduate students throughout processes. also graduate‐student‐led initiatives increase their own exposure activities such as transdisciplinary‐focused seminars symposiums, volunteering local conservation groups, participating internships outside academia.

This study focuses on the deposition of microplastics (MPs) urban beaches along central São Paulo coastline, utilizing advanced methodologies such as remote sensing, GNSS altimetric surveys, µ-Raman spectroscopy, and machine learning (ML) models. MP concentrations ranged from 6 to 35 MPs/m2, with highest densities observed near Port Santos, attributed industrial port activities. The predominant types identified were foams (48.7%), fragments (27.7%), pellets (23.2%), while fibers rare (0.4%). Beach slope orientation found facilitate concentration deposition, particularly for pellets. study’s ML models showed high predictive accuracy, Random Forest Gradient Boosting performing exceptionally well specific categories (pellet, fragment, fiber, foam, film). Polymer characterization revealed prevalence polyethylene, polypropylene, polystyrene, reflecting sources disposable packaging raw materials. findings emphasize need improved waste management targeted beach cleanups, which currently fail address smaller MPs effectively. research highlights critical role combining in situ data understand dynamics coastal environments. It provides actionable insights mitigation strategies contributes global efforts aligned Sustainable Development Goals, SDG 14, aimed at conserving marine ecosystems reducing pollution.

Macro- and microplastics trace metals are significant pollutants in the marine environment have been reported all ecosystems around world. The process of sorption/desorption by macro- is influenced various factors, including morphological characteristics microplastics, their adsorption capacity, environmental conditions. This research provides discusses laboratory experimental findings on sorption cadmium (Cd), copper (Cu), lead (Pb), zinc (Zn) polyethylene terephthalate (PETE) high-density (HDPE) within two contrasting intertidal sedimentary environments with high low organic matter content under conditions constant temperatures (T=- 4.0°C, T=+ T=+18.0°C). Our aim to determine effect temperature metal onto microplastics. Temperature alters metals’ plastic altering rate reaching equilibrium concentration, whereas had only a minor influence partitioning metals. Sediment influences dynamics at three T=- T=+18.0°C. study enhances our understanding how can metals-plastic particle interactions providing insight as that will create greatest threat higher trophic levels an additional vector Cd, Cu, Pb, Zn exposure into benthic food webs.

In this perspective paper, we discuss the negative impacts of plastics and associated chemicals on triple planetary crisis environmental pollution, climate change biodiversity loss from a multidisciplinary perspective. Plastics are part pollution crisis, threatening ecosystems human health. They also impact accelerate loss; in this, they aggravate crisis. We analyze scientific state-of-the-art to identify critical knowledge gaps regarding life cycle, release, fate, exposure, hazard governance chemicals, as well links loss. Based outcome, derive key research needs for comprehensive assessment amongst others, address largely missing regulation plastic additives in-use plastics. offer holistic bridging disciplinary expertise natural social sciences achieve effective risk management that protect Earth, its health
