Short affidavit on behalf of the Rajasthan State Pollution Control Board (RSPCB) in terms of the National Green Tribunal order dated January 22, 2025. The application was registered suo motu by the NGT on the basis of a news item titled "Toxic kilns pollution Aravallis; wildlife and locals suffer" appearing …
The Taj Mahal—an iconic World Heritage monument built of white marble—has become discolored with time, due, in part, to high levels of particulate matter (PM) soiling its surface. Such discoloration has required extensive and costly treatment and despite previous interventions to reduce pollution in its vicinity, the haze and darkening …
New Delhi: Responding to the high court's direction that there should be no biomass burning this year, Delhi government has decided to file an affidavit explaining that NASA images have proved that pollution levels in the city increase every November due to crop stubble burning in neighbouring states. Since Delhi …
Fine particulate matter from industries, cars and biomass causing premature mortality. Air pollution could have killed at least 600,000 Indians in 2012, a study conducted by the World Health Organisation and made public on Monday said. That is about a fifth of the 3 million who died worldwide because they …
Within the framework of air quality studies at the megacity scale, highly time-resolved volatile organic compound (C2–C8) measurements were performed in downtown Paris (urban background sites) from January to November 2010. This unique dataset included non-methane hydrocarbons (NMHCs) and aromatic/oxygenated species (OVOCs) measured by a GC-FID (gas chromatograph with a …
Air pollution takes huge economic toll on poor countries and costs the world more than $5 trillion annually reveals the new World Bank study on economic costs of indoor and outdoor pollution. Report seeks to estimate the costs of premature deaths related to air pollution, to strengthen the case for …
Although China's severe air pollution has become a focus in the field of atmospheric chemistry and the mechanisms of urban air pollution there have been researched extensively, few field sampling campaigns have been conducted at remote background sites in China, where air pollution characteristics on a larger scale are highlighted. …
There is a lack of knowledge of how biomass burning aerosols in the tropics age, including those in the fire-prone Northern Territory in Australia. This paper reports chemical characterization and aging of aerosols monitored during the one month long SAFIRED (Savannah Fires in the Early Dry Season) field study, with …
Winter has the worst air pollution of the year in the megacity of Beijing. Despite extensive winter studies in recent years, our knowledge of the sources, formation mechanisms and evolution of aerosol particles is not complete. Here we have a comprehensive characterization of the sources, variations and processes of submicron …
Long-term measurements (from August 2009 to December 2014) of aerosol black carbon mass concentration (MBC) and spectral aerosol optical depth (AOD) were carried out from a high-altitude location, Hanle in western trans-Himalaya as part of the Regional Aerosol Warming Experiment. Original Source
In order to understand the regional climate implications of aerosols over Indo Gangetic Plains (IGP), a major Indo-US field experiment, Ganges Valley Aerosol Experiment (GVAX) was conducted during 2011– 12. Atmospheric Radiation Measurement (ARM) mobile facility (AMF) was deployed at the northern Indo-Gangetic Plain over the high-altitude site, Manora Peak, …
Human impacts on fire regimes accumulated slowly with the evolution of modern humans able to ignite fires and manipulate landscapes. Today, myriad voices aim to influence fire in grassy ecosystems to different ends, and this is complicated by a colonial past focused on suppressing fire and preventing human ignitions. Here, …
Particulate matter is a major concern for public health, causing cancer and cardiopulmonary mortality. Therefore, governments in most industrialized countries monitor and set limits for particulate matter. To assist policy makers, it is important to connect the chemical composition and severity of particulate pollution to its sources. Here we show …
Dispelling certain myths about factors contributing to the extremely high air pollution levels in Delhi, an IIT Kanpur professor said on Monday that biomass burning and vehicles were the most important sources of PM 2.5 emissions in winter. Professor Mukesh Sharma, the author of IIT Kanpur's source apportionment study on …
In early spring the Baltic region is frequently affected by high-pollution events due to biomass burning in that area. Here we present a comprehensive study to investigate the impact of biomass/grass burning (BB) on the evolution and composition of aerosol in Preila, Lithuania, during springtime open fires. Non-refractory submicron particulate …
The atmosphere–land–water connectivity of nutrients is not altogether accounted for in the Ganges Basin despite recent studies highlighting its importance. Together with surface inputs, rivers receive N and P through atmospheric deposition (AD), directly on water surfaces, and through lateral transport. Original Source
Question raised in Rajya Sabha on Air pollution in Delhi, 14/03/2016. The National Green Tribunal (NGT) has taken note of the deteriorating Air Quality in Delhi in Original Application No. 21 of 2014 in the matter of “Vardhaman Kaushik versus Union of India and Others” and has issued directions to …
Chronic nitrogen deposition has measureable impacts on soil and plant health. We investigate burning emissions from biomass grown in areas of high and low NO x deposition. Gas and aerosol-phase emissions were measured as a function of photochemical aging in an environmental chamber at UC-Riverside. Though aerosol chemical speciation was …
Aerosol indirect effects suffer from large uncertainty in climate models and among observations. This study focuses on two plausible factors: regime dependence of aerosol-cloud interactions and the effect of cloud droplet spectral shape. We show, using a new parcel model, that combined consideration of droplet number concentration (Nc) and relative …
Judgement of the National Green Tribunal in the matter of Randhir Singh & Others Vs State of Haryana & Others dated 29/01/2016. The Application was for restraining the M/s Haryana Liquors Pvt. Ltd. from carrying on construction activity for the proposed Grain/Molasses Distillery Unit in its current location in the …
The Amazon basin is a vast continental area in which atmospheric composition is relatively unaffected by anthropogenic aerosol particles. Understanding the properties of the natural biogenic aerosol particles over the Amazon rainforest is key to understanding their influence on regional and global climate. While there have been a number of …
