Bioavailability of polycyclic aromatic hydrocarbons in the North Sea

Article Abstract:

Mytilus edulis (blue mussels) and semipermeable membrane devices (SPMDs) were used to assess the bjioavailable fraction of polycyclic aromatic hydrocarbons (PAHs) from oil field produced water in the North Sea. The mussels and SPMDs were deployed at 5,10, and 50m depth, discharge point 100 and 300m downstream, and at reference site 16km away. The concentration of PAHs increased significantly in both mussels and SPMDs toward the discharge point. The strongest contribution was that of lower molecular weight compounds (naphthalene, phenanthrene, dibenzothiophene, and their C1-C3 alkyl homologues.

Distributions of three- to seven-ring polynuclear aromatic hydrocarbons on the deep sea floor in the Central Pacific

Article Abstract:

In 20 deep sea surface sediments, three- to seven-ring parent and alkylated polynuclear aromatic hydrocarbons (PAHs) were determined. Except for perylene and retene, the latitude distribution of PAHs show that they are low in low latitudes and higher in higher latitudes.

Development of a reproductive performance test for endocrine disrupting chemicals using pair-breeding fathead minnows (Pimephales promelas)

Article Abstract:

Researchers from the University of Sussex showed that 4-nonylphenol has the greatest effect in endocrine disruption among fish. A pair of fathead minnows (Pimephales promelas) are used as test subjects for the chemical.
