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 …
Foliar surface undergoes several structural and functional changes when particulate-laden air strikes it. An attempt was made to evaluate the quality of air in terms of respirable suspended particulate matter (RSPM), suspended particulate matter (SPM), sulphur dioxide (SO2) and nitrogen dioxide (NO2) along with biochemical parameters of twelve selected roadside …
This paper examines the feasibility of implementing a congestion tax for the city of Chennai in the State of Tamil Nadu. Based on secondary data, it calculates the time cost, fuel cost and cost of emissions due to congestion and makes recommendations regarding the effective design and application of such …
On December 1, 2014, COMARNAT, the national regulatory committee of the Secretariat of Environment and Natural Resources (SEMARNAT), approved a proposed update by SEMARNAT to existing emissions standards regulating particulate matter (PM), nitrogen oxides (NOX), hydrocarbons (HC) and carbon monoxide (CO) from heavy-duty diesel engines and vehicles, including trucks, buses …
The present study reports on the abundance of reactive nitrogen (NH3 and NO2) at two sites, i.e. Okhla (urban site) in Delhi and Mai (rural site), located in the nearby state: Uttar Pradesh. The measurements were carried out during the period from October, 2012 to September, 2013 on a monthly …
This study establishes a baseline inventory of the number, types, and approximate distribution of DG sets in use in the Kathmandu Valley of Nepal and estimates air pollution emissions, including black carbon, from these generators. The study collates available national and city-level data on diesel consumption, electricity generation and demand, …
As per analysis of the Washington DC-based global research organisation World Resources Institute (WRI) for 2011, China, comprising almost 20 per cent of the world’s population, was the world’s leading emitter of carbon dioxide (CO2), with 28 percent emissions. The United States, with less than 5 per cent of world’s …
Humans increase the amount of reactive nitrogen (all N species except N2) in the environment through a number of processes, primarily food and energy production. Once in the environment, excess reactive nitrogen may cause a host of various environmental problems. Understanding and controlling individual nitrogen footprints is important for preserving …
A nitrogen (N) budget for Denmark has been developed for the years 1990 to 2010, describing the inputs and outputs at the national scale and the internal flows between relevant sectors of the economy. Satisfactorily closing the N budgets for some sectors of the economy was not possible, due to …
This report presents an overview and analysis of air quality in Europe from 2003 to 2012. It reviews progress towards meeting the requirements of the air quality directives and gives an overview of policies and measures introduced at European level to improve air quality and minimise impacts.
Wheat Found To Be Most Affected Ground ozone is affecting crop yield across the country , with wheat being the worst hit. Maharashtra stands on top of the list of states where the percentage yield of wheat has been impacted the most. Researchers said the countrywide collective crop yield loss …
China’s largely unregulated ports and shipping system generate significant air pollution that imposes a huge health and environmental burden and contributes to the country’s over 1 million pollution-related deaths each year, according to a new report released by the Natural Resources Defense Council (NRDC). China is now home to seven …
Scientists Say Pollution To Reach Dangerous Levels Despite Warm Weather Delhiites are likely to breathe in severely polluted air the day after Diwali. At present, the capital's air quality is hovering in the category range of `moderate' and `very poor' according to the national air quality index launched by the …
The air quality in Hong Kong is expected to worsen later today after pollution readings hit "very high" and "high" in various areas, the Environmental Protection Department (EPD) warned on Wednesday. The air quality health index (AQHI) – which measures the risk of hospital admissions due to air pollutants – …
This study, a meta-analysis of PEMS data from EU (Euro 6) and US (Tier 2 Bin 5/ULEV II) diesel passenger cars, documents the wide discrepancy that exists between official certification or type-approval emissions of nitrogen oxides (NOx) from new diesel passenger cars and actual NOX emissions from those vehicles during …
With traffic ceasing almost completely all areas saw steep drops in nitrogen oxide levels. Cities around Israel experienced dramatic drops in air pollution levels on Yom Kippur – the sole day in the year when traffic essentially ceases to flow – with Jerusalem and Gush Dan boasting a decrease of …
In a single year alone, India's ozone pollution damaged millions of tons of the country's staple crops which could have fed a third of its poor. According to a study published last month in Geophysical Research Letters, surface ozone pollution damaged six million metric tons of India's wheat, rice, soybean …
Nitrous oxide (N2O) is the predominant ozone-depleting substance and contributes approximately 6% to overall global warming. Terrestrial ecosystems account for nearly 70% of total global N2O atmospheric loading, of which at least 45% can be attributed to microbial cycling of nitrogen in agriculture. The reduction of N2O to nitrogen gas …
Ambient air quality monitoring was carried out in the vicinity of dam and nearby residential sites in four river basins in Karnataka with reference to SPM, RSPM, SO2 and NOx, employing Envirotech APM-460 Respirable Dust Sampler with provision to keep impingers having absorbing reagent. Further, three different methods of Air …
State Govt's Autonomous Institute To Rate Gujarat Cities On Pollution Soon, you will be able to rate the quality of air we breathe based on real-time pollution parameters monitored by sophisticated instruments. For the first time, the aut tonomous arm of state forest t and environment department, the Gujarat Environment …
Concerned over frequent fires at the Perungudi and Kodungaiyur dump yards and snowed under by complaints from residents about air pollution and health hazards, the Tamil Nadu Pollution Control Board decided to install realtime continuous air quality monitoring stations in these areas. It has been almost two years since plans …
