Use of Caged Nucella Lapillus and Crassostrea Gigas to Monitor Tributyltin‐Induced Bioeffects in Irish Coastal Waters
Abstract Caging studies have been previously reported to be useful for providing valuable information on biological effects of mollusks over short periods of time where resident species are absent. The degree of imposex in caged dog whelk (Nucella lapillus) , was measured using the vas deferens sequ...
