Order of the National Green Tribunal in the matter of News Item titled “CSE report finds dangerous increase in ozone pollution across urban India” appearing in Down to Earth dated 06.08.2024. The Principal Bench of the NGT heard the matter on March 21, 2025. In the original application, registered suo …
Steady-state and dynamic gas exchange responses to ozone visible injury were investigated in an ozone-sensitive poplar clone under field conditions. The results were translated into whole tree water loss and carbon assimilation by comparing trees exposed to ambient ozone and trees treated with the ozone-protectant ethylenediurea (EDU). Steady-state stomatal conductance …
With car ridership set to boom by 106 per cent, Delhi's air pollution and congestion crisis is bound to worsen, warns a survey by Centre for Science and Environment (CSE). Calling for transport planning that hinges on sustainability, equity, and a people-centric approach, the CSE survey, released on World Environment …
“At this rate, the Capital will be gasping for breath by 2021” Delhi's air quality is worsening and if urgent action is not taken we will have a serious problem at hand, warns Centre for Science and Environment's latest report card. “The summer of 2012 is a grim reminder of …
On World Environment Day, this report card from Centre for Science and Environment (CSE) warns that Delhi's air pollution and congestion crisis will worsen this decade if urgent action is not taken and calls for radical improvements in public transport. On this World Environment Day, Centre for Science and Environment …
The paper presents the nature of annual cycles of tropospheric ozone, cloud occurrences, NO2, rainfall, SO2, SPM, CO, non-methane hydrocarbon and surface solar radiation for the period October 2004 to June 2009 over Alipore (22.52°N, 88.33°E), India. Annual cycle of low-level cloud occurrences depicts that the low-level cloud over Alipore …
New Delhi: It’s that time of the year when the scorching sun saps the energy out of you. But if you have been feeling hotter in certain parts of the city, blame it on the ‘urban heat island (UHI) effect.’ Heat islands — as they have been termed by scientists …
A harried parent called a few weeks ago. She wanted to know if pollution levels in Delhi were bad and, if so, how bad. The answer was simple and obvious. But why did she need to know that? Her daughter’s prestigious school (which I shall leave unnamed) had sent a …
The primary drivers of the Northern Hemisphere expansion of the tropical climate zone over the past several decades are shown to be the recent increases in black carbon aerosols and tropospheric ozone rather than in greenhouse gases, which contribute to a lesser extent.
Fossil fuel combustion and fertilizer application in the United States have substantially altered the nitrogen cycle, with serious effects on climate change. The climate effects can be short-lived, by impacting the chemistry of the atmosphere, or long-lived, by altering ecosystem greenhouse gas fluxes. Here we develop a coherent framework for …
California on Wednesday released an updated draft of its cap-and-trade regulations that for the first time includes language that would link its carbon market to a similar scheme in the Canadian province of Quebec. The draft language called for the mutual acceptance of compliance instruments like allowances and offset credits …
A research team has developed a new monitoring system to analyze and compare emissions from man-made fossil fuels and trace gases in the atmosphere, a technique that likely could be used to monitor the effectiveness of measures regulating greenhouse gases. The University of Colorado Boulder-led team looked at atmospheric gas …
The new air conditioners have been designed on the basis of European and International safety standards Godrej Appliances today said it has started manufacturing the world's first ozone and climate-friendly air-conditioners, Godrej EON Green Balance, range of five star air conditioners. "We are delighted to be the first one to …
A NEW study suggested that ‘’thirdhand smoke’’- the invisible remains of cigarette smoke that deposits on carpeting, clothing, furniture and other surfaces- may be even more of a health hazard than previously thought. The study has extended the known health risks of tobacco among people who do not smoke but …

Many municipal water treatment plants utilize Ozone Treatment Systems to produce clean water for residential and industrial users. While all the various types of water treatment systems have their advantages and disadvantages. Ozone systems provide excellent disinfection and avoid some of the chemical byproduct problems experienced with the use of …
Data on surface ozone concentration compiled for a 10-year period from 1990 to 1999 for Pune and Delhi are analyzed in terms of its frequency distribution, annual trend, diurnal variation and its relation with various meteorological and chemical parameters. It is found that the surface ozone concentration range showing highest …
In the present study a monitoring work is under taken to estimate the black carbon aerosol of 4 different cities representing 4 different zones of Odisha state. The monitoring was carried out from December 2008 to November 2009 to study the role of aerosol contamination in different atmospheric condition.
China said Friday that two-thirds of its cities currently fail to meet new air-quality standards introduced this week that are based on the pollutants most harmful to health. Under pressure from a worried Chinese public, the government this week issued revised air-quality targets based on the smallest particulates, which make …
Non-completion of the Western and Eastern Peripheral Expressway to divert traffic of heavy vehicles is costing the national Capital’s health dearly. According to a study, the city has the highest level of air pollutants called particulate matter less than 10 microns (PM10). To make matters worse, the PM10 levels have …
