Prof. Margarita Stoytcheva graduated from the University of Chemical Technology and Metallurgy of Sofia, Bulgaria. She has a Ph.D. and DSc in Chemistry and Technical Sciences. She has been a researcher and teacher at several universities in Bulgaria, Algeria, and France. From 2006 to the present, she has participated in activities of scientific research, technological development, and teaching at the Institute of Engineering, University of

Baja California, Mexicali, Mexico, as a full-time researcher. Since 2008 she has been a member of the National System of Researchers of Mexico, and since 2011 she has been a regular member of the Mexican Academy of Sciences. Her interests and areas of research are electroanalytical chemistry and biotechnology.

Dr. Zlatev obtained his master's degree from the University of Chemical Technology and Metallurgy of Sofia, Bulgaria, and his Ph.D. from the Grenoble Institute of Technology, France. After his work as a researcher at the Bulgarian Academy of Sciences, Dr. Zlatev began working as a senior researcher and laboratory head at the Institute of Engineering, University of Baja California, Mexicali, Mexico. He is a regular member of the Mexican

Academy of Sciences and the Mexican National System of Researchers. Dr. Zlatev has authored more than 110 publications in prestigious scientific journals and holds 10 patents in analytical and electroanalytical chemistry, spectroscopy, corrosion, and analytical instrumentation.

Preface

*Arsenic Monitoring, Removal and Remediation* is organized into two sections

The two chapters in the first section comment on the principal methods for determining arsenic levels in environmental samples, such as atomic absorption spectrometry, inductively coupled plasma mass spectrometry, inductively coupled plasma-atomic emission spectrometry, X-ray fluorescence, molecule adsorption spectrophotometry, and others, with emphasis on sample pretreatment, extraction, separation, and method validation techniques for arsenic speciation analysis. Special attention is paid to the electrochemical methods for arsenic quantification as an alternative to the aforementioned techniques and to the potential of the differential

alternative pulses voltammetry for arsenic determination in the presence of

The three chapters in the second section highlight the benefits of using adsorption for arsenic species removal and suggest remedial approaches against arsenic pollution. The strategies discussed include traditional arsenic treatment technologies such as oxidation, coagulation-flocculation, adsorption, ion exchange, and membrane filtration, along with more sustainable arsenic remediation methods such as

The book offers solutions to problems associated with arsenic speciation, determination, and remediation. It launches a call to action to avoid arsenic pollution.
