No abstracts are to be cited without prior reference to the author.Surveys of gastropod (dogwhelk, Nucella lapillus) populations at the Shetland Oil Terminal in Sullom Voe for the effects of tributyl tin (TBT) from shipping have been commissioned by the terminal’s Environmental Advisory Group (SOTEAG) and now represent one of the longest time-series of biological effects data available (1987–2009). These data from 20 shoreline sites around the oil terminal in the Voe and less affected waters of Yell Sound, show a substantial recovery of TBT-induced imposex as measured by vas deferens sequence index (VDSI), relative penis size index (RPSI), and female sterility associated with decreasing shipping traffic, reduced usage of free-association antifoulants and now the complete ban imposed by the International Maritime Organization (IMO) on TBT usage on large vessels in 2008. Data are presented that show in 2009, for the first time and following the IMO ban, no incidence of imposex-induced female sterility at any ...
