Economic valuation of ecosystem services of selected interventions in agriculture in India

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 …

Electric cars could cut oil imports 40% by 2030, says study

Massive switch to electric cars could save drivers £1,000 a year on fuel costs, if infrastructure is built to support the vehicles Electric cars could cut the UK’s oil imports by 40% and reduce drivers’ fuel bills by £13bn if deployed on a large scale, according to a new study. …

Accelerating progress from Euro 4/IV to Euro 6/VI vehicle emissions standards

This brief presents the technical details and benefits of leapfrogging to Euro VI heavy-duty emission standards and Euro 6 light-duty emission standards rather than progressing through Euro 5/V. As many countries model their vehicle emission standards after those developed for the EU, the lessons learned in the European market should …

Comparison of real-world off-cycle NOX emissions control in Euro IV, V, and VI

Heavy Duty Vehicles conforming to Euro IV and V standards frequently show poor real-world NOx emissions performance. Evidence indicates that new certification protocols in Euro VI resolve this problem, and Euro VI-compliant HDV NOx emissions meet expectations.

Real-case simulations of aerosol–cloud interactions in ship tracks over the Bay of Biscay

Ship tracks provide an ideal test bed for studying aerosol–cloud interactions (ACIs) and for evaluating their representation in model parameterisations. Regional modelling can be of particular use for this task, as this approach provides sufficient resolution to resolve the structure of the produced track including their meteorological environment whilst relying …

The impacts of firework burning at the Chinese Spring Festival on air quality: insights of tracers, source evolution and aging processes

To understand the impact of firework-burning (FW) particles on air quality and human health during the winter haze period, 39 elements, 10 water-soluble ions and 8 fractions of carbonaceous species in atmospheric PM2.5 in Nanjing were investigated during the 2014 Chinese Spring Festival (SF). Serious regional haze pollution persisted throughout …

South Africa: Minister Grants Reprieve to Meet Minimum Emissions Standards

The Minister of Environmental Affairs, Edna Molewa, said on Tuesday the department had decided to grant several companies reprieve in order to meet minimum air emissions standards. The department has processed 35 applications, including 16 from Eskom, Sasol, Anglo American, PPC and a number of refiners, for compliance with the …

Effect of biomass burning over the western North Pacific Rim: wintertime maxima of anhydrosugars in ambient aerosols from Okinawa

Biomass burning (BB) largely modifies the chemical composition of atmospheric aerosols on the globe. We collected aerosol samples (TSP) at Cape Hedo, on subtropical Okinawa Island, from October 2009 to February 2012 to study anhydrosugars as BB tracers. Levoglucosan was detected as the dominant anhydrosugar followed by its isomers, mannosan …

A global analysis of soil acidification caused by nitrogen addition

Nitrogen (N) deposition-induced soil acidification has become a global problem. However, the response patterns of soil acidification to N addition and the underlying mechanisms remain far from clear. Here, we conducted a meta-analysis of 106 studies to reveal global patterns of soil acidification in responses to N addition. We found …

Climate forced air-quality modeling at urban scale: sensitivity to model resolution, emissions and meteorology

While previous research helped to identify and prioritize the sources of error in air quality modeling due to anthropogenic emissions and spatial scale effects our knowledge is limited on how these uncertainties affect climate forced air-quality assessments. Using as reference a 10 yr model simulation over the greater Paris (France) …

Application of WRF/Chem version 3.4.1 over North America under the AQMEII Phase 2: evaluation of 2010 application and responses of air quality and meteorology–chemistry interactions …

The Weather Research and Forecasting model with Chemistry (WRF/Chem) simulation with the 2005 Carbon Bond gas-phase mechanism coupled to the Modal for Aerosol Dynamics for Europe and the Volatility Basis Set approach for Secondary Organic Aerosol (SOA) are conducted over a domain in North America for 2006 and 2010 as …

Modelling street level PM10 concentrations across Europe: source apportionment and possible futures

Despite increasing emission controls, particulate matter (PM) has remained a critical issue for European air quality in recent years. The various sources of PM, both from primary particulate emissions as well as secondary formation from precursor gases, make this a complex problem to tackle. In order to allow for credible …

On optimization of air pollution and electricity production of thermal power plants of Delhi using goal programming

Air pollution is a serious problem in today’s rapidly developing world. Burning of fossil fuels has been the source of air pollution since ages. Coal is a major source of electricity production in India. About 56% of total electricity produced is from Thermal Power Plants (TPPs). In Delhi we have …

Air Pollution and Atherosclerosis: A Cross-Sectional Analysis of Four European Cohort Studies in the ESCAPE Study

In four European cohorts, we investigated the cross-sectional association between long-term exposure to air pollution and intima-media thickness of the common carotid artery (CIMT), a pre-clinical marker of atherosclerosis.

72% पॉल्यूशन आपकी गाड़ियों से

दिल्ली दुनिया के सबसे प्रदूषित शहरों में शुमार है। वह दिन दूर नहीं, जब यह जगह रहने लायक ही न बचे। हमें इसे रोकना है। एनबीटी आज से शुरू कर रहा है नई पहल जिसमें कोशिश होगी कि पॉल्यूशन से निबटने के उपायों की जानकारी हम आप तक पहुंचाएं : …

Not cars, dust pollutes Delhi most: MoEF

SC Told Vehicles Contribute Just 6.6%, Dust's Share Is 52% The major source of pollution in the capital is dust particles and not vehicular emissions, the ministry of environment and forest (MoEF) submitted before Supreme Court on Wednesday . While dust contributed 52% of particulate matter in the air, pollutions …

An empirical model to evaluate SPM concentration in a colliery area

Jharkhand, a state in India is rich in minerals particularly coal. Large number of mines is excavated here. Opening of new mines and expanding existing mines causes air pollution. The main pollutants emitted are suspended particulate matter, oxides of nitrogen, sulphur dioxide and carbon dioxide. In this paper empirical models …
