| Abstract | A new approach to identify multiple sources of polycyclic aromatic hydrocarbons (PAHs) and to evaluate the source contributions to the atmospheric deposition of particulate PAHs is proposed. The approach is based on differences in the concentrations of the sums of PAHs with the same molecular weight among the different PAH sources. Data on PAH accumulation in snow, as well as source profiles, were used for calculations. The contributions of an aluminum production plant, oil-fired central heating boilers, and residential wood and coal combustion were calculated using linear mixing models. The concentrations of PAH pairs such as benzo[b]fluoranthene+benzo[k]fluoranthene and benzo[g,h,i]perylene+indeno[1,2,3-c,d]pyrene normalized to benzo[a]anthracene+chrysene were used as tracers in the mixing equations. The results obtained using ratios of PAH pairs were compared with those obtained using molecular diagnostic ratios such as benzo[a]anthracene/chrysene and benzo[g,h,i]perylene/indeno[1,2,3-c,d]pyrene. It was shown that the results obtained using diagnostic ratios as tracers are less reliable than the results obtained using the ratios of the sums of PAHs. |

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.
