| Abstract | In order to study the concentrations of hydrogen peroxide (H$_{2}$O$_{2}$) and the factors controlling its concentrations, we monitored concentrations of H$_{2}$O$_{2}$ and other gases such as sulfur dioxide, ozone, and NO$_{x}$ as well as meteorological factors such as air temperature, relative humidity, and wind direction/speed during eight measurement periods from 2000 to 2002 in a Japanese red pine forest in Japan. The H$_{2}$O$_{2}$ concentrations ranged from below 0.01 to 1.64 ppb, and analysis of the diurnal variation in H$_{2}$O$_{2}$ concentration showed high concentrations around noon, and low concentrations in the morning and late afternoon. The H$_{2}$O$_{2}$ concentrations were high in early summer, when O$_{3}$ concentration, temperature, and solar radiation were high, and were low in fall, when O$_{3}$ concentration, temperature, and solar radiation were low. We propose that O$_{3}$ concentration affects the production of H$_{2}$O$_{2}$ in the monitored region during the period under study, but that high H$_{2}$O$_{2}$ concentrations were sometimes caused by the transport of polluted air from urban regions. H$_{2}$O$_{2}$ concentrations decreased remarkably when SO$_{2}$ concentrations increased by transported volcanic emission on Miyake Island. In the absence of the effects of SO$_{2}$, H$_{2}$O$_{2}$ concentrations increased with increasing O$_{3}$ concentration and temperature. |

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.
