| Abstract | In this study we have used 193 ArF excimer laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), to produce a high resolution (32 mum) shells record of Mn, Zn, Sr, Ba, Mg, Cr, Cu, As, Cd, Co and Pb for the Periglypta reticulate and Tridacna gigas mussel shells from the Yalong bay, Hainan Island of China. Our synthesized $CaCO_{3}$ co-precipitation multi-elements discs as the solid matrix- matched standards for calibration, and 42 bCa was selected as the internal standard to compensate the draft of signal. The results also demonstrated our co-precipitation matrix matched calibration method was more appropriate than the commercial NIST610/612 glass standards calibration method. Validation of the matrix- matched LA- ICP-MS technique indicated that the method provides accurate and reproducible (RSD<10%) analysis of trace elements in shells (0.01~3000 mug/g). The detection limits of this method for these elements were obtained in the range of 0.103 to 0.709 mug /g with correlation coefficients (R) better than 0.993. The proposed method was successfully applied to determine the trace elements in the two shells. The high-resolution trace element profiles could be as an environmental proxy and biogeochemical cycling for the area in which the fish or mussel lives. |

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.
