TL;DR: In this paper, the exposure profiles indicate an important lag between the excretion of the two metabolites: the maximum of 3-OHB a P urinary excretion is observed 10 to 17 hours after the 1-OHPy maximum, with a much closer correlation ( r = 0.81) than that obtained with both metabolites in real time ( r < 0.21).

TL;DR: In this paper, surface sediments from six sampling sites in the Cotonou lagoon were used to assess the urban runoff contribution of polycyclic aromatic hydrocarbons accumulation in this ecosystem.

TL;DR: In this article, diesel exhaust particulate matter (DEP) extracts were collected from three commercial diesel engine vehicles and DEP extracts (DEPEs) were prepared from each, and the estrogenic and antiestrogenic activities of the DEPE samples were examined using an estrogen response element (ERE)-driven luciferase reporter gene assay in MCF-7 human breast cancer cells.

TL;DR: The ability of Sphingomonas paucimobilis strain EPA 505 (a soil bacterium capable of utilizing fluoranthene as the sole source of carbon and energy for growth) to metabolize 3-methyl-methylfluoranthene, 7-methlybenz[a ]anthracene, 5-methylchrysene, and their corresponding unsubstituted parent hydrocarbons was investigated.
