| Abstract | In our previous studies we assessed the biochemical response of juvenile seabream to the exposure to three selected polycyclic aromatic hydrocarbons (PAHs) (phenanthrene, pyrene and fluorene) in short-term laboratory experiments. Since in the analyses conducted in the field it is much more natural to expect the presence of multiple contaminants at the same time, the objective of this study was to analyse the reaction of seabream to the exposure to a mix of the three PAHs tested previously. The proportions of the individual components in the PAH mix used in our experiments were constant and determined on the basis of the concentration addition concept. We measured a set of hepatic biomarkers: 7-ethoxyresorufin-O-deethylase (EROD), glutathione-S-transferase (GST), catalase (CAT), superoxide dismutase (SOD) and lipid peroxidation; as well as biliary fluorescent aromatic compounds (FACs) metabolites. Moreover, we calculated the biotransformation index, the condition factor and the hepatosomatic index. Only a few of these indicators provided statistically significant response to the tested exposures, while FACs showed very strong increase with increasing concentration of the tested mix of PAHs. The results of this research are expected to contribute to the establishment of a good biochemical index of exposure to mixtures of PAHs in laboratory experiments, which can be further useful in field studies dealing with the impact of organic pollutants on marine organisms. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
