This volume discusses the adsorptive profiles of microplastic (MP) pollutants, covering their structural identity, sorption ability and degradation due to photolytic, hydrolytic, mechanical, and other environmental factors. In addition to the quantitation of (MPs) in the environment, the book unveils the deleterious effects on aquatic species and humans due to adsorbed inorganic/organic contaminants on the surface of MPs. The present book finds its uniqueness by presenting in-depth discussions on the interactions and mechanisms of microplastics with organic pollutants, microalgae, and human systems. The interactions and mechanisms between microplastics and microalgae are explored to understand the possible remediation pathways in microplastic contaminated water resources. Students and researchers in the fields of environmental science and engineering, biotechnology, aquaculture, marine technology, and water chemistry can benefit from this book. Furthermore, industries, NGOs and stakeholders dealing with wastewater, solid waste/environmental pollution will find this book useful.
