Pesticides Remediation Technologies from Water and Wastewater focuses on environmental aspects and health effects of pesticides, the use of conventional and AOPs technologies, and adsorption processes and nanomaterials for the removal of pesticides from water and wastewater. The deterioration of water quality is of great concern due to its effects on aquatic organisms, humans and the ecosystem. Among the pollutants, pesticides are a major concern in villages and farm land. This edited book bridges the gap between old and new knowledge about the categorization of pesticides, the presence of them in water, wastewater, soil and foods, and new methods to detect them from water matrices. This edited book provides the necessary basic knowledge to new researchers who want to learn about pesticides and the ways to eliminate them in aqueous matrices. Moreover, it is also a helpful resource for mature researchers in this field, providing them with new trends in water and wastewater treatment processes, preparation and application of novel adsorbent materials.
