Introduction The biogeochemical cycling of nitrogen is of vital importance due to the role of nitrogen in both aquatic and terrestrial ecosystems. 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

氨是一种化学活性气体，通过与酸云液滴中的硝酸盐(NO3−)和硫酸盐(SO42-)结合，加速颗粒物的形成，从而降低空气质量。自工业化前时代以来，由于农业活动和化肥使用的增加，全球NH3排放量增加了一倍以上。在本研究中，选取了夏季(丰收季节)Jhajjar地区农村站点的特定时段(以事件为基础)进行环境NH3监测。 研究PM2.5和PM10中主要水溶性无机物质的昼夜变化及活性氮物质的作用——为期两年的研究 //www.a-i-l-s-a.com/index.php/vol16no2021/investigating-day-and-nighttime-variability-of-major-water-soluble-inorganic-species-and-role-of-reactive-nitrogen-species-in-pm25-and-pm10-a-two-year-study/ 2021-06-10 2021-07-28 Subhash Chandra, Monika Kulshrestha, Ruchi Singh 第16卷，特刊:活性氮

引言大气的物理化学性质受到颗粒物的影响，从而改变其组成，从而可能改变环境空气质量、能见度、云的形成以及地球系统进入、吸收、反射和发射的能量。此外，它还会对人类健康产生不利影响，并可能改变生态系统4-6。因此，PM的化学特性对于制定空气质量改善计划来控制

是必要的。

该研究报告了2012年和2013年德里市中心一个地点的细态和粗态颗粒物中主要水溶性无机物质(WSIS)的昼夜变化。PM2.5和PM10的2年主要离子种类(NH4+、K+、Ca2+、Mg2+和NO3-、SO42-)浓度均显示夜间阳离子和阴离子的平均水平均高于白天。PM2.5

Introduction The predominant cause of indoor air emissions globallyand in most developed countries is incomplete burning of biomass; it is burnt open and creates a lot of smoke1,2.The biomass smoke contains a wide range of high-risk pollutants, such as coarse, small, and ultrafine particulate matter, carbon monoxide, nitrogen and sulfur oxide, transitional metals, polycyclic, aromatic, and bio-aerosol compounds3. Recent studiesin rural home revealed that the main sources of indoor air pollu

Introduction When the neo-Malthusians were busy in predicting the impending food crisis across the world due to burgeoning levels of population, little did they conceive of a situation where the food production would outstrip the rate of population growth. 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

Introduction Air pollution is perceived as a major issue due to increased urbanization and industrialization. Nitrogen is a major atmospheric constituent. It makes up around 78% by volume of the Earth&rsquo;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-
