Agriculture is multi-functional, producing economic goods including food, feed, fibre, and fuel, as well as providing several intangible or non-tradable services to society free of cost. Non-tradable services, unlike economic goods, remain unpriced; as a result, farmers are not compensated monetarily for the benefits of the several non-tradable services they …
Over the course of six years (2006–2011), equivalent black carbon (eqBC), coarse aerosol mass (PM 1–10), and surface ozone (O 3), observed during the monsoon onset period at the Nepal Climate Observatory–Pyramid WMO/GAW Global Station (NCO-P, 5079 m a.s.l.), were analyzed to investigate events characterized by a significant increase in …
The largest coal-fired power plant in the West will produce one-third less energy by 2020 and could close in 2044 under a proposal that the federal government adopted to cut haze-causing emissions of nitrogen oxide at places like the Grand Canyon. The U.S. Environmental Protection Agency announced Monday that the …
KARACHI: Pakistan is a country of 188 million people with average population density of 236 persons per square kilometre, which is higher as compared to many other developing countries. The country has very high migration rate to urban centres which has made the cities very congested and turned the civic …
Traffic noise has been associated with prevalence of hypertension, but reports are inconsistent for blood pressure (BP). People’s noise exposure indoors might be essential to ascertain effects and disentangle them from those suspected for traffic-related air pollution.
Poor air quality not only harms human health; it also impacts the structure and function of ecosystems, often far away from the emission sources. This report focuses on the deposition of airborne sulphur (S) and nitrogen (N) compounds and their negative effects on ecosystems. N- and S-containing air pollutants are …
Nitrous oxide (N2O) is a potent greenhouse gas (GHG) that also depletes stratospheric ozone. Nitrogen (N) fertilizer rate is the best single predictor of N2O emissions from agricultural soils, which are responsible for ∼50% of the total global anthropogenic flux, but it is a relatively imprecise estimator. Accumulating evidence suggests …
The extent of urban air pollution in Pakistan—South Asia’s most urbanized country—is among the world’s most severe, significantly damaging human health, quality of life, and the economy and environment of Pakistan. The harm from Pakistan’s urban air pollution is among the highest in South Asia, exceeding several high-profile causes of …
This paper addresses a longstanding debate regarding the factors that limit nitrogen fixation by diazotrophic plankton—the primary source of an essential nutrient to the ocean. Multiple lines of evidence show that diazotroph growth can be locally limited by the atmospheric iron supply, but large-scale rates of N2 fixation are ultimately …
5921–5941One seventh of the world's population lives in the Indo-Gangetic Plain (IGP) and the fertile region sustains agricultural food crop production for much of South Asia, yet it remains one the most under-studied regions of the world in terms of atmospheric composition and chemistry. In particular, the emissions and chemistry …
The heat has been unbearable and worse news follows. The summer pollution curve has taken an ugly turn as ground-level ozone, a highly reactive and harmful gas, has far exceeded the permissible limit, a report released by the Centre for Science and Environment (CSE) on Monday said. “With heat wave …
There is a pressing need to verify air pollutant and greenhouse gas emissions from anthropogenic fossil energy sources to enforce current and future regulations. We demonstrate the feasibility of using simultaneous remote sensing observations of column abundances of CO2, CO, and NO2 to inform and verify emission inventories.
The various quarry sites in the vicinity could be attributed to high RSPM concentrations in this region, the report added. People living in Mumbai and Navi Mumbai have been breathing polluted air, which falls under the “poor to severe” category for a considerable number of observations throughout 2013-14, found a …
Indian Institute of Toxicology Research report cites addition of 1,28,217 vehicles on capital roads as main reason. Charbagh has emerged as the most polluted area in Lucknow, according to a bi-annual report released by Indian Institute of Toxicology Research Thursday on World Environment Day. According to the report by the …
Respiratory suspended particle in the city’s air is way above the permissible level. Ambient air quality data of Chandigarh suggest that despite all the efforts, air quality is still a matter of concern in the City Beautiful especially the steady rise of mono-nitrogen oxides (NOx) in the city’s air since …
Air quality in urban areas is a cause of concern because of increased industrial activities that contribute to large quantities of emissions. The study assess levels and variations of carbon monoxide (CO), nitrogen dioxide (NO2) and sulfur dioxide (SO2) in Blantyre, Malawi using a stationary environmental monitoring station (EMS). Results …
Diesel cars emit around three times more NOx pollution in congested traffic than is permitted in current European emissions tests, according to research by Imperial College London and Emissions Analytics. The study analysed the exhaust emissions of 12 diesel cars, all of which met today’s euro 5 emissions standard when …
The Center for Alternative Fuels, Engines and Emissions (CAFEE) at West Virginia University (WVU) was contracted by the International Council on Clean Transportation (ICCT) to conduct in-use testing of three light-duty diesel vehicles, using a portable emissions measurement system (PEMS), over a variety of pre-defined test routes exhibiting diverse driving …
Maharashtra Pollution Control Board (MPCB) has established Ambient Air Quality Network in Maharashtra covering major cities to comply with the mandate of Air (Prevention & Control of Pollution) Act, 1981 and to disseminate status of air quality prevailing in the state of Maharashtra. The ambient air quality is monitored by …
Emission of nitrogen oxide jumps from 3.17 g/km to 119.2 g/km if the vehicle is loaded by 30 per cent, says a CRRI study From potholes to slow-moving traffic, the Capital’s roads have a host of problems that make the daily commute of many Delhiites an ordeal. Now, according to …
