However, global nitrogen cycle is being disturbed by the unchecked increase in food and energy production resulting in the accumulation of Reactive Nitrogen (Nr) in various environmental matrices. Generally, Nr refers to any formof nitrogen compound that is biologically active, photo chemically reactive and radioactively active in the biosphere a

..]]> Ammonia is a chemically active gas which accelerates particulate matter formation by combining with nitrate (NO3−) and sulphate (SO42-) in acid cloud droplets, thereby reducing air quality. Since pre-industrial times, NH3 emissions have more than doubled globally, owing to increase in agricultural activities and fertilizer usage. In this study, ambient NH3 monitoring was done during selected periods on event basis in summer season (kharif crop) at a rural site of Jhajjar district of Ha

Moreover, it can also affect human health adversely and may also alter the ecosystem4-6. Therefore, the chemical characterization of PM is necessary for the development of an air quality improvement programme to control

The two years’ concentrations of major ionic species (NH4+, K+, Ca2+ and Mg2+ and NO3-, SO42-) showed that mean levels of both ?cations and ?anions were higher in nighttime than daytime in both PM2.5 and PM10. Moreover, the difference of mean levels in daytime and nighttime was noticed higher in PM2.5

Recent studiesin rural home revealed that the main sources of indoor air pollu

Here in this study we examined the health risk from the smoke emitted due burning of biomass fuels while cooking in rural houses in West Bengal. Out of numerous gaseous pollutant this study selected NO2 component to find out the health risk of women. NO2 has been monitored in kitchen and adjacent living room in N= 30 households in three season namely summer, monsoon and wint

This has been made possible in large measure due to the increased production of the variegated nitrogenous inputs that have served to amplify the levels of food production1. A direct consequence of this has been the intensification in nit

Considering the major hotspot of atmospheric reactive nitrogen (N) emission, three sites in Indo-Gangetic plain (IGP) were selected based on different local source parameters. Results have shown that gas phase reactive N contribute up to 90% of total analy

The study was performed in herbal garden of Jamia Hamdard, New Delhi. The plants were treated with graded treatments (60,120,180 kg N ha-1) of N alone and in combination with seedling inoculation withAzotobacter.

Nitrogen is a major atmospheric constituent. It makes up around 78% by volume of the Earth’s atmosphere. The inert nitrogen is utilized by converting into different reactive compounds such as NH3, NO2, protein, urea etc. These nitrogen compounds are called reactive nitrogen species (Nr) which are chemically, biologically, photo chemically and radioactively active species1-

When present in excess amount in air, it causes adverse effects for the environment and human health.Different air pollutants when scavenged through rains are deposited on the surface. The chemical composition of rain water is an indicator of the levels of different air pollutants in the region. The present study reports the concentrations of Dissolved Organic Carbon (DOC) and the reactive nitrogen species (NO3- and NH4+)
