A colorimetric sensor array has been developed to differentiate various micro- and nanoplastic particles (MNPs), both pristine those coated with a protein corona, in buffered water. This utilizes five distinct cross-reactive chemo-responsive dyes, which exhibit changes visible optical absorbance upon interaction MNPs. Although no single dye responds exclusively either or protein-corona-coated MNPs, the collective shifts color across all dyes create unique molecular fingerprint for each type of MNP. method demonstrates high sensitivity, capable detecting MNPs sizes (50 nm, 100 2 μm) differentiating them from controls at concentrations as low 10 ng/mL using standard chemometric techniques, ensuring accurate results without error.

Marine litter and non-degradable plastic pollution is of global concern. Regular monitoring programs are being established to assess understand the scale this pollution. In Europe, goal European Strategy Framework Directive (MSFD) trends in Good Environmental Status support large-scale actions at regional level. requires tailored sampling strategies, protocols indicators, that align with specific objectives for local or needs. addition, uneven spatial temporal distributions marine present a challenge when designing statistically powerful program. paper, we critically review existing Europe. We discuss main constraints, including environmental, logistical, scientific, ethical factors. Additionally, outline critical gaps shortcomings MSFD beaches/shorelines, floating litter, seafloor microplastics, harm. Several priorities must be shape future within MSFD. Recent developments analytical approaches, optimizing gaining better understanding spatiotemporal heterogeneity its implications survey design replication, inclusion newly validated methodologies have achieved sufficient technical readiness, considered. Although there well-established methods assessing beaches, it will necessary implement schemes microplastics sediments invertebrates as robust become available targeting smaller particle size classes. Furthermore, indicators entanglement injury organisms considered near future. Moreover, following enhance effectiveness efforts: (1) creating an inventory accumulation areas sources types (e.g., fishing gear), (2) riverine inputs (3) atmospheric (4) accidental during extreme weather events, (5) studying how species risk may transported by litter. provide recommendations long-term, effective, well-coordinated achieve comprehensive accurate EU waters. This allow development measures mitigate impacts eventually evaluate success respective measures.

Abstract Micro- and nanoplastics (MNPs) are ubiquitous environmental pollutants representing a concern for human health. MNPs have been detected in placentas, indicating that during pregnancy maternal exposure may lead to placental transfer foetal exposure, with potential adverse effects on early-life development. However, comprehensive risk assessment (RA) framework, specific is lacking. Here, we propose novel roadmap assist the development of an health RA MNPs. This designed based established chemical, mixture, particle, MNP strategies aligned standard components (problem formulation, hazard identification, characterisation, assessment, characterisation). We systematically work through these stages identify what needed progress impacts MNPs, including information missing, be used interim. While challenges such as complex physicochemical properties limited toxicity data at relevant levels, uncertainties related characterising exposures described elsewhere, our discusses how specifically impact significance presence biological samples factors influencing bioaccumulation transfer. Additionally, introduce new technology readiness levels methods detection matrices. Importantly, this review integrates broad scope into one document, providing unified resource. highlight requirements areas targeted research, dose-response relationships assessing By addressing gaps, aims advance robust ultimately enhancing understanding mitigation risks associated
