Air pollution is a major environmental concern detrimental to all living forms, mostly resulting from industrial, vehicular, and natural activity. These pollutants exacerbate global warming and pose health risks, including respiratory ailments and malignancies. The interplay of air pollution, nanomaterials, and bioremediation is a multifaceted field of research that examines the impact of pollutants on the environment and the capacity of nanoparticles to improve remediation strategies. Nanomaterials have potential in environmental applications, especially in the elimination of contaminants from air and water. They may serve as vectors for pollutants and facilitate the degradation of toxins in bioremediation techniques. The interaction between nanomaterials and contaminants may enhance toxicity, requiring more investigation into their environmental impacts. Sources of air pollution may be classified as natural (wildfires, volcanic eruptions) or man-made (traffic, industrial activity). Comprehending the interplay between nanoparticles and bioremediation is essential for formulating successful pollution abatement techniques. Bioremediation employs biological agents such as bacteria and plants to rehabilitate damaged areas, with nanoparticles potentially augmenting their efficacy. Nonetheless, ethical concerns and possible health hazards must be addressed. This chapter shows the investigation efforts that concentrate on the secure and efficacious use of nanomaterials, guaranteeing their beneficial influence on environmental cleanup while mitigating emerging hazards. Policymakers must acknowledge the interrelation of these components when developing laws and evaluating the ecological and health implications of nanomaterials.
