| Abstract | The extent to which accumulations of polycyclic aromatic hydrocarbons (PAH) by semipermeable membrane devices (SPMD) may be correlated to the concentration of PAH metabolites in fish was examined. Atlantic cod (Gadus morhua) and SPMD were exposed over a 4-wk period to a mixture that was designed to simulate the composition of PAH in produced water discharges in the North Sea. Fish bile and whole SPMD were analyzed after exposure in a high, low, and a control treatment tank. PAH metabolites were detected and quantified by means of high-performance liquid chromatography (HPLC) or gas chromatography-time-of-flight mass spectroscopy (GC-ToF-MS) and PAH in SPMD by gas chromatography-mass spectroscopy (GC-MS). The level and duration of exposure were generally reflected in both matrices. Exposure water concentrations, calculated from SPMD accumulations, showed some considerable differences from nominal concentrations for volatile compounds. Concentration factors (CF) for fish based on SPMD-derived water concentrations ranged from 2.9 to 354.3 L/g. CF increased with hydrophobicity with more variation at higher log K(ow). Regression analysis of accumulations of individual compounds in fish and SPMDs showed reasonable but compound-specific correlation, r2 = .54-.85 (C1-phenanthrenes/anthracenes and pyrene, respectively). Comparison of the two exposures suggests that fish CF may not be entirely independent of water concentrations. Overall the results show that accumulation of up to four-ring PAH in SPMD may be related to internal exposure of fish to these substances when exposed through water, as evidenced by metabolite concentrations. The usefulness of using SPMD to measure exposure concentrations in a large-scale flow-through study is also examined. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
