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 …
Chronic exposure to traffic-related air pollution (TRAP) may contribute to premature mortality, but few studies to date have addressed this topic. This study assessed the association between TRAP and mortality in Toronto, Ontario, Canada.
Asia's increasing population and economic growth has meant that the energy demand is doubling every 10 years, which is more than twice the world average, resulting in an increased risk of human exposure to higher air pollution from fossil fuel burning. In countries, where more than third of the population …
The IGSD press release on a joint proposal by Micronesia and Mauritius for phasing down HFCs which could otherwise be responsible for 1/3rd of total climate emissions by 2040. The U.S. is also considering submitting its own proposal on HFCs to the Montreal Protocol. Two island nations, Micronesia and Mauritius, …
China is on track to meet its pollution targets by 2010 even though it is still struggling to deal with its coal-dependent energy sector, the country's environment minister has reported to parliament. By the end of 2010, China aims to cut the emissions of major pollutants by 10 percent compared …
An expansion of sea ice around Antarctica is linked to a hole in the ozone layer high in the atmosphere, according to a study on Tuesday that helps clear up a mystery about global warming. The findings, by scientists at the British Antarctic Survey (BAS) and the U.S. space agency …
The Sub Regional Workshop on Ozone Depleting Substances (ODS) Phase Out in Military Applications would be a stepping stone for a wider environment military network in Sri Lanka, said former Executive Secretary National Protocol Secretariat, UNEP K. Madhava Sharma. Sharma who is also the Member of Technology and Economic Assessment …
The government has decided to do something important about vehicular emissions that have reached highly dangerous levels. Federal Ministry of Environment told the National Assembly on Monday that all petrol-run vehicles would be required to comply with Euro-II emission standards with effect from July. The deadline for diesel vehicles' compliance …
Long-term human exposure to ambient pollutants can be an important contributing or etiologic factor of many chronic diseases. Spatiotemporal estimation (mapping) of long-term exposure at residential areas based on field observations recorded in the U.S. Environmental Protection Agency
A field study was conducted to evaluate the impact of ambient ozone on mustard (Brassica campestris L. var. Kranti) plants grown under recommended and 1.5 times recommended NPK doses at a rural site of India using filtered (FCs) and non-filtered open top chambers (NFCs). Ambient mean O3 concentration varied from …
In this paper, an analysis of data from continuous ambient air monitoring station in Hyderabad is reported to better understand daily and seasonal trends of particulates and chemistry of ozone pollution in the atmosphere. The objective of the paper has been to investigate the contribution levels of transport emissions to …
Draft new EU legislation that would limit harmful vapour emissions from petrol pumps was proposed on 4 December by the European Commission. Petrol vapour contains benzene, which is known to cause cancer, and contributes to the formation of ground-level ozone, one of the air pollutants that is most damaging to …
Ozone technology has been used for the past two decades or more. It is, however, only now that its use in wastewater treatment has been recognized. The location of ozone use in wastewater treatment determines the goal of treatment. At the same time, ozone finds use in each stage of …
Ozone pollution is produced by photochemical processes involving nitrogen oxides and volatile organic compounds in the lower atmosphere. Ozone levels become particularly high in regions close to high ozone precursor emissions during summer episodes with stagnant meteorological conditions, when high insolation and temperatures persist. In 2008, levels continued to exceed …
Environmental air pollutants are inhaled as complex mixtures, but the long dominant focus of monitoring and research on individual pollutants has provided modest insight into pollutant interactions that may be important to health. Trends toward managing multiple pollutants to maximize aggregate health gains place increasing value on knowing whether the …
The development of modern biofuels for various energy applications is gaining momentum - both in terms of applications and impacts. Liquid biofuels for transport received special attention in the literature and numerous studies on the sustainability (economic and environmental) of large-scale biofuels production continue to be undertaken. This includes large …
