NEW DELHI: Restraining explosive growth of vehicles on Delhi's roads and rationing their movement were identified as key actions for improving the capital's air quality months before Kejriwal government announced its decision to allow cars with odd and even numbers on alternate days from January 1. In the rounds of …
The 'milky white' nature of fog and associated haze that has shrouded Delhi with the onset of winter show that pollution has not yet spiked to last year's level, a top expert said, indicating that the worst is yet to come. The city's air quality, that "became better" post Diwali …
Transport sector has always been a significant contributor in emission estimates of cities. The source apportionment studies conducted in the six major cities of the country have shown that transport has significant contributions in PM2.5 and NOx concentrations. Moreover, the lower height of release of vehicular emissions leads to higher …
This study by the International Gas Union (IGU) highlights the interconnection that exists between reducing greenhouse gas emissions and reducing emissions of other air pollutants. It presents case studies of efforts in four cities — New York, Istanbul, Toronto, and Beijing — that have tackled or are tackling the issue …
Question raised in Rajya Sabha on Air Pollution in metropolitan cities, 30/11/2015. The National Ambient Quality Standards (November 2009) comprises of 12 pollutants, namely, PM10, PM2.5, SO2, NO2, O3, CO, NH3, Benzene, lead, Arsenic, Nickel, BaP (particulate phase). The ambient air quality is monitored in 254 cities, towns, and industrial …
This report presents an updated overview and analysis of air quality in Europe. It is focused in the state in 2013 and the development from 2004 to 2013. It reviews progress towards meeting the requirements of the air quality directives. An overview of the latest findings and estimates of the …
This paper investigates the relationship between local air pollution and urban structure with an emphasis on urban fragmentation. Using a unique dataset of 249 Large Urban Zones (LUZ) across Europe, a Bayesian Model Averaging selection method is employed to empirically identify the determinants of within-LUZ concentration of three air pollutants: …
The recent Volkswagen corporate fraud has exposed gaps in emissions regulations in India and makes the country "extremely" vulnerable as it is "dieselizing" rapidly without the right norms and compliance framework for manufacturers, a green body said today. Centre for Science and Environment CSE) said that the Volkswagen fraud was …
ENVIRONMENT MINISTRY WILL TELL STATE BOARDS TO ASK LOCAL AGENCIES TO TAKE STEPS AGAINST POLLUTION In the backdrop of deteriorating air quality due to meteorological reasons and stubble burning, the Union environment ministry on Friday decided to set up a control room at the Central Pollution Control Board (CPCB) to …
Recent studies have shown that exposure to particulate black carbon (BC) has significant adverse health effects and may be more detrimental to human health than exposure to PM2.5 as a whole. Mobile source BC emission controls, mostly on diesel-burning vehicles, have successfully decreased mobile source BC emissions to less than …
Come winter, and the air quality in northern India begins to deteriorate.The smoke resulting from burning crop residues combined with vehicular emissions make the air we breathe deadly. A major reason for the poor air quality is the burning of paddy stubble by farmers in Punjab and Haryana. This practice …
Come winter, and the air quality in northern India begins to deteriorate. A thick blanket of smog (mixture of smoke and fog) engulfs the National Capital Region which reduces visibility and gives a tough time to commuters. A major reason for the poor air quality is the burning of paddy …
The study was carried out during the months of September-October, 2015 to assess the status of air quality of Lucknow city by monitoring and assessment of some selected air pollutants namely Respirable Particulate Matter (RSPM or PM10), Fine particles (PM2.5), Sulphur dioxide (SO2), Oxides of Nitrogen (NOx) and trace metals-Lead …
CSE’s exposure monitoring indicates dramatic drop of 60 per cent in PM2.5 levels compared to levels observed the previous day. This is supported by official ambient air quality monitoring that shows 45 per cent drop in overall PM2.5 levels across the city due to low traffic on the national holiday …
Satellite remote sensing of tropospheric nitrogen dioxide (NO2) can provide valuable information for estimating surface nitrogen oxides (NOx) emissions. Using an exponentially modified Gaussian (EMG) method and taking into account the effect of wind on observed NO2 distributions, we estimate 3-year moving-average emissions of summertime NOx from 35 US (United …
In another 10 years, Delhi will record the world's largest number of premature deaths due to air pollution among all mega cities in the world. However it will be another Indian city - Kolkata that will record the highest number of such deaths by 2050. Kolkata will see its number …
The air quality of Delhi over the past one week has worsened from moderate and poor to very poor. Particulate Matter (PM) 2.5 and 10 remain the major pollutants. The National Air Quality Index shows the figure reaching an alarming 391 (showing the high level of PM 10) at stations …
Air contaminated with pollutants such as ozone and tiny particles could cause the premature death of about 6.6 million people a year by 2050 if nothing is done to improve air quality, warns this study published in the journal Nature Assessment of the global burden of disease is based on …
Aerosol particles can directly alter the radiation balance by scattering and absorbing incident solar radiation, thus decreasing the amount of light reaching the surface and increasing the fraction of diffuse radiation—the so-called ‘aerosol direct radiative effect’. Using the Moderate Resolution Imaging Spectroradiometer aerosol products, the aerosol direct radiative effects under …
The main objective of the air quality index (AQI) system is to interpret air quality in a standardized indicator to enable the public to understand the likely health and environmental impacts of air pollutant concentration levels monitored on any given day. The daily averaged concentration data of air pollutants of …
