Plastics are crucial materials that are used in daily life. They are manufactured and used until they become waste that negatively impacts the environment and public health. These plastic wastes break down into small particles known as microplastics (MPs) via changes in environmental conditions (i.e., sunlight, temperature, weathering, and irradiation). This reduction in size increases the toxic potential of MPs. This book provides a comprehensive overview of MPs, including the challenges and advances in their effective removal from our environment.
