Wood treated with chromated copper arsenate (CCA) is primarily disposed within construction and demolition (C&D;) debris landfills, with wood monofills and municipal solid waste (MSW) landfills as alternative disposal options.
In CCA-containing lysimeters, the organoarsenic species monomethylarsonic acid (MMAA) and DMAAwere virtually absent in the monofill lysimeter and observed in the C&D; and MSW lysimeters.

For the past 60 yr, chromate-copper-arsenate (CCA) has been used to pressure-treat millions of cubic meters of wood in the United States for the construction of many outdoor structures.
The generated leachates were analyzed for inorganic As (III) and As (V) and the organoarsenic species, monomethylarsonic acid (MMAA) and dimethylarsinic acid (DMAA), using high-performance liquid chromatography followed by hydride generation and atomic fluorescence spectrometry (HPLC-HG-AFS).

A laboratory incubation experiment was conducted to investigate the influence of organic matter content on arsenic speciation and mobilization in chromated copper arsenate (CCA)-contaminated soils.
Changes in water-soluble arsenic speciation (As (V), As (III), MMAA, DMAA) were monitored over time in soil extracts by HPLC-ICP-MS and in the soil solid phase (As (III), As (V)) by a solvent extraction method.
