Abstract: Paper reports on a study of imposex on the dog-whelk Thais (Nucella) lapillus. One hundred and forty-seven samples of dog-whelks were collected from counties Donegal, Mayo, Galway, Clare, Kerry, Cork, Wicklow, Dublin and Louth. Mulroy and Ballinakill Bays were sampled in detail. Habitat, collection time, the number of adults, their size and the presence of any source of TBT were recorded. A sample of 50 adults from each station was examined and their sex, any physical deformities, and the size of both male and female penises recorded.
