Within the framework of the Terms of Reference Plan for normalization commission 39011 on Leaching characteristics of building and waste materials, the National Institute of Public Health and the Environment (RIVM) is developing a set of leaching tests for various organic compounds. Laboratory investigations were performed for leaching tests of phenol and methylphenols (cresols) to assess the practical feasibility of the experimental set-up, the level of emissions and the reproducibility of the experiments. Additional experiments were performed to investigate the losses of phenols during the test. Leaching tets for phenols, based on Dutch pre-NVN 7344 and 7350, were performed on four different soils. The materials contained high levels of contaminants to ensure detectable leached quantities. With reference to the performance, the methods could be applied for phenols as well. In three of the soils, a high emission could be observed, especially in the first fractions of the eluates. For one soil, no leaching was found at all. Apparently, the phenols were not available as a result of an unknown characteristic element in that specific soil. The levels of emission from the (highly contaminated) materials were high in the range from 30 to 60 % relative to the soil concentrations. Levels were higher than ealier was found for PCBs and EOX, probably as a result of the higher water solubility of the phenols. Standard deviations (n=2) were good for most leaching test (2-20%).
