“…MPs are analyzed through several stages, such as separation, identification, visualization, and quantification. Techniques used to characterize MPs are mainly microscopic (optical microscopy, fluorescence microscopy, Scanning Electron Microscopy—SEM, Transmission Electron Microscopy—TEM, and Atomic Force Microscopy—AFM) and spectroscopic (Fourier Transform Infrared Spectroscopy—FT-IR, Raman Spectroscopy—RS, Nuclear Magnetic Resonance—NMR) methods [ 270 , 271 , 272 , 273 , 274 , 275 , 276 , 277 , 278 , 279 , 280 , 281 , 282 , 283 , 284 , 285 ] ( Figure 7 ). They are mostly used to identify the polymeric composition of MPs, analysis of the shape, color, and size of the particles, as well as their quantity in test samples.…”

Microplastics Derived from Food Packaging Waste—Their Origin and Health Risks

Plastics are commonly used for packaging in the food industry. The most popular thermoplastic materials that have found such applications are polyethylene (PE), polypropylene (PP), poly(ethylene terephthalate) (PET), and polystyrene (PS). Unfortunately, most plastic packaging is disposable. As a consequence, significant amounts of waste are generated, entering the environment, and undergoing degradation processes. They can occur under the influence of mechanical forces, temperature, light, chemical, and biological factors. These factors can present synergistic or antagonistic effects. As a result of their action, microplastics are formed, which can undergo further fragmentation and decomposition into small-molecule compounds. During the degradation process, various additives used at the plastics’ processing stage can also be released. Both microplastics and additives can negatively affect human and animal health. Determination of the negative consequences of microplastics on the environment and health is not possible without knowing the course of degradation processes of packaging waste and their products. In this article, we present the sources of microplastics, the causes and places of their formation, the transport of such particles, the degradation of plastics most often used in the production of packaging for food storage, the factors affecting the said process, and its effects.

“…Microplastics, one of the emerging contaminants, have been reported from nearly all the environmental matrices such as surface water, groundwater, marine water, snow/glaciers, soil, atmosphere, aquatic/terrestrial biotic species including humans, food items, and even from the remotest places on the earth such as Arctic and Antarctica. [51][52][53][54][55][56][57][58][59][60] Presence of these particles has also been detected in the human lungs, blood, saliva, breast milk, colon, stool, urine, and placental tissues indicating their entry into the human body through ingestion and inhalation. [61][62][63][64][65][66][67][68] Retaining the physicochemical properties of plastics, these tiny particles are able to affect human health as well as the environment to a signicant extent.…”

“…The release of toxic compounds and organic contaminants into the environment poses risks to human health and the sustainability of water resources [1–5] . Water pollution occurs when water bodies, such as rivers, lakes, and groundwater, become contaminated with various substances that have harmful effects [6–10] . These pollutants can come from industrial activities, agricultural practices, improper waste disposal, sewage discharge, and other human activities.…”

MXene has indeed gained significant attention in recent years as a promising photocatalyst for various applications, including photocatalytic degradation of pollutants. MXene possesses several unique physical and chemical properties that make it suitable for such applications, including its uniform planar structure, strong metal conductivity, effective functional groups, and numerous derivatives. These properties contribute to the excellent photodegradation performance and long‐term stability exhibited by MXene‐based photocatalysts compared to other photocatalysts. MXene‐based composites, which are formed by incorporating MXene with other materials, demonstrate even better photodegradation activity due to their abundant active sites and porous structure. One crucial factor influencing the photodegradation performance of MXene‐based photocatalysts is the presence of active functional groups on the surface of MXene. These functional groups play a significant role in the photocatalytic process and contribute to the overall efficiency of the catalyst. To provide a broader understanding of MXene‐based photocatalysts, the physicochemical properties of MXene are briefly described in this review. This includes its structural characteristics, electrical conductivity, and the presence of functional groups. This review also investigates the physical and chemical synthesis routes for preparing MXene, both in its natural state and as composites with other materials. These synthesis methods are essential for tailoring the properties of MXene‐based photocatalysts to meet specific requirements. Finally, the review discusses future work and challenges in MXene‐based photocatalysis. This field holds great promise for addressing environmental concerns and improving the degradation of organic compounds. However, further research is needed to optimize the synthesis methods, enhance the photocatalytic efficiency, and explore the practical applications of MXene‐based photocatalysts.
