Several sediment characteristics were analyzed to
determine their suitability for use as potential
normalization factors for the bioavailability of neutral
organic compounds sorbed to sediments. Percent organic
carbon, cation exchange capacity and particle surface area
were measured sediment characteristics that varied
sufficiently to encompass the range in observed sediment
toxicity. Laboratory sediment toxicity test data using
fluoranthene suggest that there is no biologically
significant correlation between sediment toxicity and
sediment characteristics (organic carbon, cation exchange
capacity, particle size distribution, particle surface
area). Fluoranthene amended sediments with similar organic
carbon contents do not yield similar toxicities due to
sorbed fluoranthene and thus do not support the organic
carbon normalization approach for evaluating sediment
quality or for sediment criteria development.I'll :::: 11 WVW '- - -; ---- ON@" 1101111111 11111111,100181 1 IN ommommil
