TI  - A survey of in vivo benzo[alpha]pyrene metabolism in small benthic marine 
      invertebrates.

AB  - A micro-extraction technique was used to examine in vivo polycyclic aromatic 
      hydrocarbon (PAH) metabolism in 10 small invertebrate species exposed to 
      sediments amended with 3H-benzo[alpha]pyrene (BaP). Phyla examined included 
      Mollusca (Hydrobia totteni, Ilyanassa obsoleta, Yoldia limatula, and Gemma 
      gemma), Annelida (Nereis succinea, Pectinaria gouldii, Haploscolopolous sp., and 
      Capitella sp. 1) and Arthropoda (Edotea triloba, and Gammarus mucronatus). 
      Organisms were exposed to BaP-labeled sediments, harvested, and parent BaP 
      separated from all polar metabolites by liquid extraction The percent of 
      BaP-derived radio-activity present as polar metabolites ranged from 96% for N. 
      succinea to 7% for P. gouldii. Wide ranges in metabolic capability were also 
      observed between species in the other two phyla examined. Reverse-phase HPLC 
      analysis of extracts of representative species from each phyla indicated that all 
      these organisms form bay region metabolites, with two species forming the 
      7,8-dihydrodiol (N. succinea and G. mucronatus). In light of the high variability 
      in metabolic capability observed within each phylum, species-specific information 
      on metabolic ability should be obtained before assessing bioaccumulation, 
      critical body burdens, or trophic transfer of PAHs in invertebrates.
