Although Ag toxicity in terrestrial organisms has been studied extensively,

Eisenia fetida earthworms to artificial OECD soil spiked with a range
of concentrations of Ag (AgNPs or AgNO3). The main aims were to (1)
identify the location and form of accumulation of Ag in the exposed
earthworms and (2) better understand the physiological mechanisms
involved in Ag detoxification. The results showed that similar doses
of AgNPs or AgNO3 did not have the same effect on E. fetida survival.
The two forms of Ag added to soil exhibited substantial differences
in speciation at the end of exposure, but the Ag speciation and content
of Ag in earthworms were similar, suggesting that biotransformation
of Ag occurred. Finally, 3D images of intact earthworms obtained
by X-ray micro-computed tomography revealed that Ag accumulated preferentially
in the chloragogen tissue, coelomocytes, and nephridial epithelium.
Thus, E. fetida bioaccumulates Ag, but a regulation mechanism limits
its impact in a very efficient manner. The location of Ag in the
organism, the competition between Ag and Cu, and the speciation of
internal Ag suggest a link between Ag and the thiol-rich proteins

Today, there are many research groups that focus on remedying the adverse effects of our industrialized society, which release compounds daily, increasingly polluting the environment. This book compiles the most important work of distinguished scientists around the world who are at the vanguard in this discipline, covering the environments of soil and water, as well as a great variety of microorganisms and mechanism bioremediators. Thus, the bioremediation strategy and bioremediator should be chosen according to the pollutant. This material is one of the few available for discussion in literature, and the authors and editorial board hope that this book can be used as a guide or as a base material useful for people who want to develop or apply new strategies in the bioremediation field. The book consists of the following sections: 1) bacterial bioremediation, 2) microbioremediation, 3) phyto- and phycoremediation, 4) composite bioremediation and finally 5) derivative bioremediation. Each section is disposed depending on the kind and type of pollutant; inorganic or organic; and by the complexity of organic mixtures. Studies include in silico, in vitro, in situ, ex situ approaches, from mathematical models to real landscape cases, including analytical methods to assess bioremediation efficacy and the biotechnological use of rhamnolipids, acetogenins, surfactants, micro-bubbles, agricultural residues and enzymes to improve or achieve bioremediation.
