Sources, Types, and Occurrences of Microplastics in Soil, Water, and Air

The presence of microplastics in the world's water bodies is an urgent and pressing issue that must be addressed immediately. The increasing amounts of microplastics found in water bodies and sediments highlight the crucial need for comprehensive waste management strategies that can reduce plastic consumption while also improving recycling and waste disposal systems. The prevalence of microplastics in water raises serious concerns about their potential influence on both aquatic ecosystems and human health. According to research, a wide variety of aquatic animals, including fish, shellfish, and plankton, can swallow microplastics. Ingestion of microplastics is thought to increase the risk of physical injury, disrupting feeding and digestive processes, and transferring hazardous compounds. However, the specific implications of microplastic consumption are still being investigated. The major goal of this chapter is to provide a complete overview of the origins, classification, and environmental prevalence of microplastics in India and around the world. This chapter aims to shed light on the complex character of the microplastics problem by investigating the numerous types and sources of microplastics, as well as their distribution and abundance in various environmental contexts. It also seeks to understand the intricate relationships between environmental dynamics, human activities, and the spread of microplastics. It also aims to catalyze future research into microplastic mitigation and management by identifying significant research gaps and emphasizing critical research needs. Finally, this chapter aims to serve as a catalyst for educated decision-making, policy formulation, and collective action to address the growing worldwide challenge of microplastic contamination.
