TL;DR: Partitioning of combustion-derived PAHs between water and sediment may be much less than predicted, possibly because associations with particles are much stronger than expected, and this reduced partitioning may produce erroneous results in predicting bioaccumulation where uptake from water is important.

TL;DR: Radiometric and GC analyses for BaP in both sediment and tissues suggested that not all of the BaP extracted chemically from sediment was bioavailable, and the extent of metabolism of [3H]BaP was negatively correlated to tissue concentrations of AHs, except that amphipod species accumulated higher concentrations ofAHs than did clams, indicating that other factors also influenced accumulation of AHS.

TL;DR: The results showed that all the examined indexes could discriminate among sites exhibiting different degrees of chemical contamination, and that the use of the indexes in concert appeared to enhance the assessment of contaminant exposure and sublethal effects.

TL;DR: It is shown that sole readily takes up AHs associated with sediment from urban areas and that the presence of other xenobiotics in sediment increases tissue concentrations of BaP metabolites, and that detoxication of reactive intermediates is an important factor in determining the levels of DNA modification by AHs and resulting toxic effects in feral fish.

TL;DR: Levels of PCBs and DDTs were determined in blubber of sea lions diagnosed with metastatic carcinoma and animals that had died from non-carcinoma-related incidents and age, sex, mass and length did not affect the probability of dying from carcinoma.
