We analyzed the influence of environmental parameters on the temporal variation of atmospheric carbon dioxide (CO 2) mixing ratios in two environmentally contrasting Indian sites, Dehradun (30.1°N, 77.4°E, humid subtropical station) and Gadanki (13.5°N, 79.18°E, dry tropical station), from October 2010 to September 2011. The annual range of mixing ratios is low in Gadanki as compared to those of Dehradun because of relatively less monthly variation in temperature and relative humidity (RH) at Gadanki. At both the stations, the minimum mixing ratios are present during the high ecosystem productivity seasons in the afternoon hours. The maximum values are in the early morning hours. However, low wind speed conditions control the unexpected afternoon high mixing ratios in Gadanki during the pre-monsoon season. The early morning maximum is high during monsoon and postmonsoon seasons in Dehradun and Gadanki, respectively, whereas morning inflexion occurred earlier in Gadanki compared with Dehradun. The effect of cloudiness on the CO 2 uptake depends on the canopy cover.
El monitoreo de radón en Palampur y Dalhousie, en los valles de Kangra y Chamba, utiliza la emanometría por medicióndiscreta de radón desde 1992, dentro del programa de Sismicidad del Himalaya del gobierno de la India. Se observa una correlaciónen ambas regiones investigadas con el número de microtemblores registrados por el Departamento de Meteorología de la India enel período 1992-1997. Se estudió el efecto de parámetros meteorológicos (temperatura, precipitación, humedad y velocidad delviento) sobre el nivel de radón. En la estación de Palampur se presenta correlación positiva de los niveles de radón con la temperatura,la precipitación y la humedad, y negativa con la velocidad del viento.
Hazardous wastes are man made activities, and adversely impacts human life and environment. The adverse impacts caused due to the indiscriminate disposal of hazardous wates (HWs). A number of potentially hazardous chemicals are now produced as finished products or by products.More than six million known chemicals, used in different Indian industries. Management of hazardous wastes has become a major concern in India as haphazard dumping of hazardous wastes results in severe environmental impairment. The adverse effect of hazardous as well as the significance potential risks posed by them to the life and its supporting system are increasingly recognized. Rapid growth of industries in India has resulted in generation of increasing volume of hazardous wates. However only, a few secured landfill sites are available in the country for disposal
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
