| Abstract | Cadmium, lead, copper and zinc were determined in the soft tissues of blue mussels (Mytilus edulis) sampled from four locations along the Hardangerfjord in western Norway. A source of pollution is located at the head of the fjord and the sampling was performed at various distances from this source. The results obtained in this study (1998) were compared with results from similar studies carried out in 1983 and 1992. The mean cadmium concentrations in blue mussels sampled at Måge (13 km from the source of pollution) were approximately 18 mg kg−1 fresh weight in 1983, 2.4 mg kg−1 fresh weight in 1992 and 1.1 mg kg−1 fresh weight in 1998. The mean cadmium concentrations in blue mussels sampled at Varaldsøy (105 km from the source of pollution) were approximately 5 mg kg−1 fresh weight in 1983, 0.5 mg kg−1 fresh weight in 1992 and 0.4 mg kg−1 fresh weight in 1998. The mean lead concentration in blue mussels sampled at Måge was 140 mg kg−1 fresh weight in 1983. The mean lead concentrations in 1992 and 1998 had decreased to 6 and 3 mg kg−1 fresh weight, respectively. The mean lead concentrations in blue mussels from Gravdal were 15 mg kg−1 fresh weight in 1982, 1 mg kg−1 in 1992 and less than 1 mg kg−1 fresh weight in 1998. The mean copper concentrations in blue mussels were relatively constant over this period at all locations, with a variation between 0.6 and 1.2 mg kg−1 fresh weight. The mean zinc concentration in blue mussels sampled at Måge decreased from 120 to 30 mg kg−1 fresh weight in the period between 1983 and 1998. |

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.
