Soil quality — Determination of inorganic arsenic species in soils and soil-like materials

Scope

This document specifies a method primarily developed for the determination of inorganic As(III) and As(V) species in soil. It covers the extraction of the inorganic As(III) and As(V) from soil using 0.43 M HNO3 and EDTA without a significant As species transformation during the extraction procedure and its analysis using LC-ICP-MS.
