The aim of the study was to develop and validate analytical methods for the detection and quantification of arsenic species (As(III), DMA, MMA and As(V)) in different environmental matrices, including drinking water, surface water, groundwater, and sediments. The experimental tests were performed on a HPLC 1260 Infinity II coupled with an ICP-MS 7850 Agilent. For aqueous matrices, the method was validated within a working range of 10-50 microg/L using an Agilent G3154-65002 guard column and an Agilent G3154-65001 ...
