Sediment Ecosystem Assessment Protocol (SEAP): An Accurate and Integrated Weight-of-Evidence Based System

Abstract

Public reporting burden for the collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to Washington Headquarters Services, Directorate for Information Operations and Reports, 1215 Jefferson Davis Highway, Suite 1204, Arlington VA 22202-4302. Respondents should be aware that notwithstanding any other provision of law, no person shall be subject to a penalty for failing to comply with a collection of information if it does not display a currently valid OMB control number. 5d.

Locations of sites with low-quality (25th centile) and high-quality (75th centile) observations throughout the harbor study area for three biological response variables evaluated in this study: 1) amphipod survival, 2) total abundance (benthic infauna), and 3) species richness (benthic infauna). Thresholds for the percentile values are given in Table 10 Figure 10-9. Relative probability maps generated by WLR for the harbor study area for the occurrence of sites in the 25th percentile of benthic infauna total abundance. Relative impairment probability is given as standard deviations in order to compare between maps. ....... 10-13 List of TablesFigure 10-10.

EXECUTIVE SUMMARY ObjectiveThe purpose of this research was to develop an efficient, accurate and integrated approach for the assessment of ecosystem risk and recovery at sites where contaminated sediments exist, or previously existed. The work addressed the two high priority needs identified in SERDP ERSON-07-01: 1) Develop and evaluate rapid measurement tools/ screening assays to ...

“…A espécie C. filosa do presente estudo apresenta característica biológicas semelhantes a M. juniae como elevada fecundidade, facilidade de obtenção e manutenção em laboratório. Adicionalmente os resultados obtidos com experimentos de ecotoxicidade aguda com a substância de referência sulfato de cobre sugerem sensibilidade elevada de C. filosa ao cobre (CL50-48h: 0,01 mg/L), uma vez que este valor foi 20x menor que o encontrado para M. juniae , 60 x menor que a CL50 encontrada para Corophium insidiosum Crawford 1937, 25x menor que CL50 de Elasmopus bampo Barnard 1979, (Reish 1993) e 8x menor que CL50 de cobre para Leptocheirus plumulosus (Burton et al 2011).…”
