| Abstract | In this study, we examined potential adverse health effect of particulate matter (PM) collected from industrial areas of Rourkela, Odisha, India. Results indicate that PM in these areas contains benzo[a]pyrene in addition to other unidentified molecules. Ames test revealed the above PM to be highly mutagenic. Further studies of PM in HaCaT cells suggest its DNA damaging potential which may lead to apoptosis. Generation of reactive oxygen and nitrogen species following PM exposure may be an early event in the PM induced apoptosis. In addition, the activity of cytochrome P450 (CYP450), the key xenobiotic metabolism enzyme, was found to be increased following PM exposure indicating its role in PM induced toxicity. To confirm this, we used genetic and pharmacological inhibitors of CYP450 like CYP1B1 siRNA and Clotrimazole. Interestingly, we found that the use of these inhibitors significantly suppressed the PM induced apoptosis in HaCaT cells, which confirm the crucial role of CYP1B1 in the toxic manifestation of PM. For further analysis, blood samples were collected from the volunteer donor and analyzed for immunophenotypes and comet assay to survey any change in immune cells and DNA damage in blood cells respectively. The study was performed with 55 blood samples including 32 from industrial areas and 23 people from non-industrial zone of Rourkela city. Samples had a mean±SD age of 35±6.2years (35 men and 20 women). Our investigation did not observe any significant alteration in lymphocytes (P=0.671), B cell (P=0.104), cytotoxic T cell (P=0.512), helper T cell (P=0.396), NK cell (P=0.675) and monocytes (P=0.170) of blood cells from these two groups. Taken together; this study first time reports the possible health hazards of PM from industrial areas of Odisha, India. |

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.
