“…The interaction between soil and groundwater is a complex process, involving physical, chemical, and biological mechanisms that can affect the transport and transformation of MPs (Figure b). Researchers have addressed the knowledge gap regarding the migration of MPs to groundwater by extensively discussing the interactions among rivers, seas, lakes, soil, landfill, and groundwater . This further confirms that soil–groundwater interactions serve as the predominant pathway for the migration of MPs into groundwater.…”

“…Groundwater stands as the largest reservoir of fresh water globally, constituting a staggering 97% of the Earth’s available fresh water . Notably, India, being the largest user of groundwater in the world, is dependent on this resource for 85% of its drinking needs and 60% of its irrigation requirements . Moreover, MPs may cause toxic effects, produce oxidative stress, and cause tissue damage and chronic inflammation to the human body .…”

“…Along with other municipal waste, these tobacco products’ waste also reaches up to the landfill sites. After a prolonged period, this waste becomes part of the leachate and contaminates the groundwater resources as well (Singh & Bhagwat, 2022). Studies have shown that these chemicals have toxic impacts onto the aquatic and terrestrial organisms (Micevska et al., 2006; Moerman & Potts, 2011; Mustafic et al, 2020; Novotny et al, 2011; Upadhyay et al., 2022).…”

Tobacco and its associated products are known to be harmful for health. Moreover, the waste emanating out of the production, processing, packaging, and consumption of these products is equally harmful for humans as well as other biotic/abiotic agencies.Taking into account the toxic nature of these waste products, it is necessary to have a well-defined approach to deal with this waste. Consideration of tobacco products' waste as municipal solid waste has serious implications in the long-term as it results in dumping of these wastes mixed-up with domestic waste in landfills. With time, toxic components become part of the leachate which contaminates water and soil, further leading to the contamination in food chain. Therefore, many countries are now considering this waste under the hazardous category and evolving various measures to safely dispose it off. In the light of recent researches and policies, it is time to re-consider this important public health issue.

The ubiquitous presence of microplastics in the environment has raised serious environmental and health concerns. These tiny plastic particles can enter the food chain, posing a significant threat to human health. Researchers worldwide have focused their efforts on developing strategies to mitigate microplastic pollution. This review focuses on the potential of nano/microstructured metal oxide semiconductors as effective photocatalysts for microplastic degradation. The review is divided into two sections: static metal oxides and dynamic micromachines based on metal oxides. The modifications made to nano/microstructured metal oxides such as TiO2, ZnO, bismuth oxyhalides (BiOX), NiO, Cu2O/CuO, perovskite‐like Bi2WO6, Fe3O4, etc., to enhance their degradation efficiency are thoroughly discussed and reviewed. Additionally, the photocatalytic pathways for the conversion of microplastics into C2 fuel and other value‐added products are also elaborated. The current developments in the realm of dynamic, self‐propelled, and controlled micromotors for the photodegradation of microplastics are also highlighted. The review concludes by proposing future perspectives and challenges to facilitate the remediation of microplastics in water and wastewater systems in a more effective, scalable, and environmentally friendly manner. Overall, the review emphasizes the potential of photocatalysis using nano/microstructured metal oxide semiconductors as an eco‐friendly and promising approach for microplastic degradation.
