| Abstract | The sources and the distributions of 23 polycyclic aromatic hydrocarbons (PAHs) in surface (0–5 cm depth) and subsurface (5–10 cm depth) soil in Riyadh, Saudi Arabia, were studied. Isomeric diagnostic ratios of the PAHs (the (anthracene/(anthracene + phenanthrene)), (benz(a)anthracene/(benz(a)anthracene + chrysene)), (fluoranthene/(fluoranthene + pyrene)), (indeno(1,2,3-cd)pyrene/(indeno(1,2,3-cd)pyrene + benzo(g,h,i)perylene)), and (benzo(a)pyrene/benzo(g,h,i)perylene) concentration ratios) were used to determine which anthropogenic sources of PAHs were dominant in different areas. The study area included four areas characterized by different anthropogenic activities; an urban area, an area strongly affected by traffic, a bare area, and an industrial area. The PAHs in all four area types were mainly emitted from factories and other mixed sources. The PAHs concentrations and patterns in some areas reflected the roles of anthropogenic activities in causing environmental pollution, especially the role of infrastructure projects (through emissions during the building work itself and emissions from heavy machinery and transport to and from the site). In contrast, PAHs concentrations and patterns in southern Riyadh showed that the recent improvements in the road network, which has improved traffic flow, have led to decreases in PAHs contamination caused by fuel combustion. |

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.
