Atmospheric ammonia (NH 3 ) is an important precursor gas of secondary PM 2 . 5 ; however, sparse ground-based NH 3 monitoring limits the characterization of its spatiotemporal distribution and provides insufficient observational evidence for evaluating emission inventories. To address these gaps, this study developed a spatiotemporal model to estimate monthly ground-level NH 3 concentrations at …

Per and polyfluoroalkyl substances (PFAS) are persistent contaminants of concern, yet long-term records in marine invertebrates remain scarce. We quantified 26 target PFAS and conducted suspect and non-target screening (NTS) of contaminants of emerging concern (CECs) in European lobster ( Homarus gammarus ) collected in a Western Norwegian coastal site (61°N, 5°E) between 2009–2025 (n = 115). Twe…

INTRODUCTION: Organophosphate flame retardants (OPFRs) and organophosphorus pesticides (OPPs) are widely used chemicals in daily environments. Yet, evidence linking prenatal exposure to them with cardiac structure development in offspring is scarce. METHODS: Maternal urinary levels of OPFR and OPP metabolites were measured during the first and second trimesters. Left ventricular end-diastolic vol…

Global plastic production is increasing exponentially, making microplastics (MPs; plastic particles <5 mm) ubiquitous in animals' environments. Microplastics can exhibit sex-specific toxicity and release harmful phthalate esters (PAEs), which are known endocrine disruptors in vertebrates and are often added to plastics to enhance flexibility and durability. Yet, we lack a comprehensive understand…

This study assessed air quality in a semi-enclosed train station using both personal and fixed monitoring and applied eXtreme Gradient Boosting (XGBoost) modelling to identify key factors influencing pollutant levels. The investigation also examined the effects of train idling time and engine speed on fuel consumption and pollutant emissions. Personal monitoring showed the average PM₂.…
