Potential repercussions of a mercury ban on the artisanal and small-scale gold-mining sector: a viewpoint
The ban imposed on exports of mercury from Europe and North America is a decision made in response to growing recognition that contamination from extensive emissions of the element in developing countries needs to be tackled more proactively. Stemming its flow to Artisanal and Small-scale gold Mining (ASM) – the largest user and emitter of mercury – has been identified as a key objective of the ...

Contamination levels assessment of heavy metals in road dust deposited in various types of urban traffic: a case study of Hassi Messaoud City (Algeria)
This study identified the levels and sources of heavy metal contamination in road dust from busy traffic areas in Hassi Messaoud, Algeria. A total of 13 sampling sites, including three traffic rotaries, tow highways, three downtown areas, four circulation roads and one background area, were selected for this study. The contamination levels of the heavy metals in the road dust were evaluated ...

Modelling undesirable outputs in eco-efficiency evaluation to paper mills along the Huai River based on Shannon DEA
Abstract: There are a great number of DEA models proposed to deal with ecological efficiency problems with undesirable outputs. However, which model should be used in a specific scenario or how about the discriminability of a given DEA model is hard to decide in practice. This paper uses the ecological Shannon DEA procedure based upon the existing study to obtain an ecological comprehensive ...

Anti-industrial pollution efficiency using DEA with constrained emission
DEA model is employed to estimate the anti-industrial pollution efficiency with constrained emission. This is a new set of DEA models with the sum of outputs of all DMUs being fixed. The developed DEA is used to compute anti-industrial pollution efficiency in all major cities of a province in China.Keywords: data envelopment analysis, DEA, equilibrium, frontier, programming, constrained ...

Relationship between trace elemental composition in Fraxinus pennsylvanica bark and the incidence of some respiratory diseases in Cordoba, Argentina
In order to evaluate the use of Fraxinus pennsylvanica as a biomonitor of trace elements and to investigate their relationship with the incidence of some respiratory diseases in children, bark samples of F. pennsylvanica were collected at ten sampling sites near healthcare centres in Cordoba city, Argentina, and analysed by Total Reflection X-ray Fluorescence with synchrotron radiation. Factor ...

Are your Candle Filters Stacking Up?
I recently received a call from a sulfuric acid plant operator that sounded a big alarm - as in the plant was in danger of violating environmental output regulations if an issue could not be resolved quickly. And, to top it off, he was asking me to help troubleshoot a competitor’s candle filter that a contractor had installed. You’re probably wondering why he was calling me and not ...

Towards a green economy in Europe
EU environmental policy targets and objectives 2010–2050 1 Moving towards a green economy in Europe Global economic crisis, soaring commodity prices and growing awareness of humanity's impact on the environment have pushed the 'green economy' concept into mainstream policy debate in recent years. In large part, this reflects a recognition that the prevailing model of economic growth ...

On the optimal timing of the oil pollution act: Is there more value in waiting than acting?
Following the Exxon-Valdez incident the, Oil Pollution Act was enacted by the US government in 1990 mandating double hull construction tankers operating in US coastal tankers. Traditional Cost Benefit Analysis to investigate whether this requirement is cost efficient does not include the timing of the implementation in anticipation of technological improvements or other system changes. We ...

Vehicle Emissions – How to Catch Defeat Devices
There are many vehicles that have a large impact on the environment in many places around the world. Today, pollutant emissions is a hot topic, both for legislators, the vehicle industry, and a concerned public. In the article “A Step-by-Step Methodology for Vehicle Testing to Catch Defeat Devices” by the International Council on Clean Transportation (ICCT) a methodology to catch ...

The link between economic growth and environmental quality: what is role of demographic change?
Internationally, political and academic discourse is increasingly focussed on two intensifying trends: the underprovision of environmental quality and population ageing. However, the potential interrelationship between these two phenomena has been virtually completely ignored. Importantly, the social preference for environmental care is a critical factor explaining the Environmental Kuznets Curve ...

Modelling trade and environmental linkages in China
Interactions between trade and the environment have been studied extensively as a reaction to the pressure that the accelerated pace of globalisation has placed on environment and trade. Distinguishing itself from previous work, this study focuses on a modelling analysis of the interactions between trade and the environment in China. A non-linear simultaneous equation trade and environment model ...

Assessment of riverine load of contaminants to European seas under policy implementation scenarios: An example with three pilot substances
An evaluation of conventional emission scenarios is carried out targeting a possible impact of EU policies on riverine loads to the European seas for three pilot pollutants: Lindane, Trifluralin and Perfluorooctane sulfonate (PFOS). The policy scenarios are investigated to the time horizon of year 2020 starting from chemical specific reference conditions and considering different types of ...

Political Measures for Strategic Environmental Policy with External Effects
This paper investigates an environmental policy designed to reduce the emission of pollutants under uncertainty, with the agent problem as an optimal stopping problem. We first analyze the two cases in which there are one agent and two competing agents by following Ohyama and Tsujimura (2005). When we consider a model of strategic agents, we need to analyze the external economic effect that is ...

Informing or Empowering? Disclosure in the United States and the Netherlands
Abstract: This paper studies the emergence of one particular 'new' environmental policy instrument: disclosure of emission and pollution data. Disclosure is part of a relatively new sub-set of regulatory measures, based on monitoring, transparency, citizen-empowerment and accountability. It originated in the United States but has recently attracted international attention. The attractiveness of ...

Housing, public policy and the environment in a historical perspective: lessons from Swedish post–war society
From a European perspective, housing–related expenses of Swedish households have increased considerably in real terms since the 1950s. Given that households through these consumption patterns contribute to a major share of the country's emissions of harmful substances and waste, e.g. through energy use, a qualitative analysis of critical explanations over time to the increase in ...

Open Burn/Open Detonation
Introduction: Open burn (OB) and open detonation (OD) operations are conducted to destroy excess, obsolete, or unserviceable (EOU) munitions and energetic materials. In OB operations, energetics or munitions are destroyed by self-sustained combustion, which is ignited by an external source, such as flame, heat, or a detonation wave. In this case, an auxilliary fuel may be added to initiate and ...

Environmental transfers against global warming: a credit-based program
This paper investigates the impacts of institutionalising a credit-based transfer program between developing and developed countries. Such a program is expected to become an essence of the Clean Development Mechanism in the Kyoto protocol. The provisions of financial and technological transfers are incorporated simultaneously into a dynamic game model of global stock pollution, where the ...

Modelling of air pollution from road traffic
This paper presents the basic principles of the method of calculating air pollution from road traffic in an urban built-up area. The algorithm of the method is based on the numerical integration of stationary two-dimensional partial differential equations of turbulent diffusion, with boundary conditions for the street canyons. The method consists of two modules: KALIB and STREETS, which calculate ...
