Inorganic arsenic speciation by electroanalysis. From laboratory to field conditions: A mini-review

•More than 136 papers on As speciation up to 2015/2016 are critically reviewed;•Stripping voltammetry methods (direct and indirect) for on-site determination of As(III) and As(V) are considered;•Electrochemical methods are effective techniques for trace As speciation in field analysis conditions.

The accurate on-site monitoring of arsenic in water is still an important issue for many countries. This review considers the most promising electrochemical methods for the analysis and speciation of the inorganic forms of arsenic under field conditions, with an emphasis on stripping voltammetry.
