*Arsenic - Analytical and Toxicological Studies* is a compilation of five chapters focused on ar‐ senic occurrence and chemistry, methods for arsenic determination and removal, and arsen‐

The three chapters included in the first section introduce: (1) the most commonly used tech‐ niques for arsenic quantification and speciation, such as atomic absorption spectrometry, in‐ ductively coupled plasma-mass spectrometry, and inductively coupled plasma-emission spectrometry, among others, often conjugated with separation techniques such as high-per‐ formance liquid chromatography, and (2) the various procedures applied for arsenic separa‐ tion and removal, including ion exchange, sorption, coagulation and membrane technologies. The advantages and drawbacks of the methods for arsenic determination and

The two chapters contained in the second section provide important information about: (1) the mechanism of arsenic-induced toxicology, involving arsenic interaction with critical thi‐ ols in proteins, and (2) the health risks associated with exposure to arsenic. The two case studies presented (Guanajuato, Mexico, and Bihar, India) comment in detail on the adverse

The book offers a professional multifaceted vision of several problems related to arsenic de‐
