Environmental Pollution

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.…

As long-lived filter-feeders, baleen whales integrate and reflect changes in ocean contamination, including exposure to microplastics (MPs). This study reports the occurrence of MPs in multiple tissues of North Atlantic fin whales (Balaenoptera physalus) collected off southwestern Iceland in 2023. Five tissues (blubber, muscle, liver, lung, and kidney) from eight individuals were analyzed using t…

Indoor Environmental Quality (IEQ) strongly influences students' learning outcomes, yet its impact on autistic students remains underexplored. This study investigates the relationship between IEQ parameters and behavioural outcomes of 37 autistic students (DSM-5 Levels 1-2) aged 5-12 years attending two autism-specific schools in Saudi Arabia across winter and summer periods. IEQ parameters - tem…

Long-term exposure to fine particulate matter (PM_2.5) is associated with respiratory and cardiovascular diseases. PM_2.5 consists of a complex mixture of organic and inorganic species, with toxicity varying based on its chemical composition, sources, and physicochemical properties. This study investigates the oxidative potential (OP), cellular oxidative stress, and inflammato…
