The quality of agricultural soils are always under threat from chemical contaminants, which ultimately affect the productivity and safety of crops. Besides agrochemicals, a new generation of substances invades the soil through irrigation with reclaimed wastewater and pollutants of organic origin such as sewage sludge or cattle manure. Emerging pollutants such as pharmaceuticals, nanomaterials and microplastics are now present in agricultural soils, but the understanding of their impact on soil quality is still limited. With focus on in situ bioremediation, this book provides an exhaustive analysis of the current biological methodologies for recovering polluted agricultural soils as well as monitoring the effectiveness of bioremediation.

Juan C. Sanchez-Hernandez is a professor in Environmental Toxicology and Animal Physiology at the University of Castilla-La Mancha (Spain). His research interests include the ecotoxicity of agrochemicals on non-target organisms and vermiremediation. He has published more than 70 peer-reviewed articles on these topics, and he is a frequent reviewer both for several of top journals in the field of environmental sciences as well as for a number of international research institutions.
