To determine the emission from secondary building materials after along-range exposure to leaching in practice, analyses were carried out on samples of building materials, taken from roads and the underground, from ten drilling cores. Also emission calculations on the basis of percolation analyses were carried out during the two years period before the construction of the road. Emission calculations were also carried on the basis of the leaching tests of long-range exposed building materials and on the basis of leaching data of non-leached building materials. Next to the emission calculations, the emission is predicted on the basis of leaching models in order to be able to estimate the emission for practical conditions. Those calculations were carried out for percolation dominated systems on three locations and for diffusion-controlled emission on one location. 13 figs., 27 tabs., 6 appendices, 23 refs.
