%X <p>Scanning Electron Microscopy was used to study structural changes in epicuticular vax of <em>Pinus sylvestris</em> L. with time. Changes in the contact angle of water droplets and in cuticular transpiration were also measured. By using material from a polluted and an unpolluted site it was shown that the ageing process occurs faster on polluted air, leading to greater cuticular transpiration and smaller contact angles at polluted sites.</p>
