Plastic pollution in marine environments poses ecological risks, in part because plastic debris can release hazardous substances, such as metal-based additives. While microplastics have received considerable attention as vectors of contaminants, less is known about larger macroplastics and their role in the spatial and temporal redistribution of substances. In this study, pristine, store-bought plastic items and macroplastics recovered from the North Pacific Subtropical Gyre (NPSG) were analysed using Fourier-Transform Infrared Spectroscopy (FTIR) to identify polymer types, and bulk acid digestion followed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for total metal quantification.

The global accumulation of plastic waste, exceeding 360 million tonnes annually, represents a critical environmental challenge due to their widespread use and extreme recalcitrance in natural environments. Furthermore, the end-of-life processing of bioplastics, which are often marketed as eco-friendly, remains problematic, with biodegradation often requiring industrial conditions. Enzyme-based depolymerization of polyesters, such as polyethylene terephthalate (PET) and bioplastics (e.

Plastics, particularly polystyrene (PS), are extensively used worldwide, especially in disposable packaging, which contributes to environmental pollution by generating microplastic particles. Herein, we investigated the pulmonary toxic effects of PS microplastics, focusing on airway inflammation and immune response. PS microplastic (50 nm to 1 μm) exposure was more likely to cause a severe pulmonary inflammatory response, particularly with smaller particle sizes.

Dental waste, including metal, plastic, and chemical residues, and high energy and water consumption, significantly contribute to environmental degradation. This review highlights the environmental impact of common dental materials and practices, such as amalgam, resin composites, and disposable plastics. The aim is to examine current evidence, emphasizing mercury pollution, microplastic release, and biomedical waste handling.
