Abstract The trapping efficiency of polyurethane foam (PUF) and Amberlite XAD-2 have been investigated for various OCPs. Atmospheres containing different concentrations of 16 OCPs have been generated and trapped in the solid adsorbent cartridges. Conditions such as the adsorption by the cartridges, the extraction of the compounds, the evaporation of the final solution, the breakthrough value and the analysis of the compounds by GC/ECD have been studied. The adsorption efficiency has been better on PUF than on Amberlite XAD-2. Recovery values ranging from 80% for p-p′ TDE to 105% for heptachlor are obtained, most of them being higher than 90%. The relative standard deviation values for the compounds investigated are less than 5% for a total sample amount of 0.2 μg of each compound.
