Preface

monitoring and treatments.

Publisher of this book.

In order to protect our environment it is of important to know the pollution sources, pollu‐ tants monitoring methodologies, and the different methods used for treatment of these pollu‐ tants. One of these pollutants is toxic organic compounds that are present in water, soil, plants and air. Environmental pollution with organic pollutants has increased as a consequence of the expansion of urban, human, agricultural and industrial activities. Toxic organic pollutants cause several environmental problems to our environment. The most common organic pollu‐ tants named persistent organic pollutants (POPs) are highly toxic, and very dangerous to our environment. The persistence of the organic compounds allows them to accumulate in human, animals and plant tissues and pass on more to food supply and get into our bodies cause ma‐ jor problems such as cancer and disruption of the immune system. Efficient techniques for the removal of toxic organic pollutants from water have drawn significant interest from scientists. The present book deals with several aspects of organic pollutants, especially in the light of or‐ ganic pollutants monitoring, risk assessment as well as the practical application of different techniques for removing it from the environment. The book is divided into three sections and structured on 9 chapters. The first section *"Monitoring"* represent an overview of the different methodologies for monitoring organic pollutants and their limits in soil and water. The second section *"Risk"* discuss in details organic pollutants risk to human, soil and plants, and focus on risk assessment on groundwater, compounds- levels and toxicity in aquatic environments, and chronic and mixture toxicity of the residues. The third section *"Treatment"* focus on the differ‐ ent treatment processes for the removal of organic pollutants; this includes different advanced oxidation processes, photocatalytic degradation, adsorption technique and electrokinetic re‐ mediation of organic pollutants. Scientists from different field of environmental sciences re‐ ported in this book their findings to explore monitoring, risk and treatment of organic pollutants. The book *"Organic Pollutants - Monitoring, Risk and Treatment"* offers an important information source for researchers and professionals working in water and wastewater quality
