Resumo<P>Acute toxicity of selenium (as sodium selenite) to three invertebrates common in Victorian coastal waters was determined using a continuous-flow test system. A description of the system is given. The three species were a cumacean, <I>Cyclaspis usitata</I>; juveniles of the bivalve <I>Notocallista</I> sp.; and two stocks of the laboratory-cultured amphipod <I>Allorchestes compressa</I>. Stock 1 of <I>A. compressa</I> was originally collected from Middle Spit, Western Port, and stock 11 from Somers, Western Port. The 96-h LC50 values for <I>C. usitata, Notocallista</I> sp. and stocks 1 and 11 of <I>A. compressa</I> were 6.12, 2.88, 6.17 and 4.77 mg selenium per litre respectively. The results indicated that juveniles of <I>Notocallista</I> sp. were more sensitive to selenium than adult <I>A. compressa</I>. The lack of information on the toxicity of selenium to invertebrates is indicated.</P>
