Economic Evaluation of PVC Waste Management
Abstract This study presents the main economic implications of diverting some relevant PVC waste streams from incineration to alternative options such as landfill and mechanical recycling. The analysis is based on three different scenarios. For each scenario the financial costs avoided and incurred are estimated, and the major environmental burdens are identified and quantified. As far as ...

Hazardous Waste Generation in Selected European Countries: Comparability of Classification Systems and Quantities
Executive summary Background & methodology The purpose of this report is to review existing data on hazardous waste for the period 1993-1996 and to try to improve the comparability of the data. The report has been prepared by the European Topic Centre on Waste (ETC/W) as part of the work programme of the European Environment Agency (EEA). Austria, Denmark and Ireland are included in ...

Trading NOx in the North-east USA
Controlling ozone raises thorny issues. Daniel Chartier examines the US ‘cap and trade’ approach to the problem. The problem of ozone in the Northeastern US has been a persistent one. Throughout the North-eastern and Mid-Atlantic US the federal National Ambient Air Quality Standard (NAAQS) for ground level ozone is exceeded repeatedly each summer. Despite attempts to deal with the ozone issue ...

What Directors Need to Know about Corporate Social Responsibility
The discussion about corporate social responsibility (CSR) is really a special type of discussion about corporate governance, and is therefore highly relevant to the role of the corporate director. This paper aims to help corporate directors appreciate CSR’s relationship to the exercise of corporate power, and equip them to engage with executives on the strategic question of how to manage the ...

European Union Targets Health Hazards
Last summer, the European Commission adopted the so-called European Environment and Health Strategy, which is better known as the SCALE Initiative. Its objectives are to reduce the disease burden caused by environmental factors in the European Union (EU), identify and prevent new health threats caused by these factors, and strengthen policymaking capacity in this area. A strong link The ...

UST Systems: Inspecting And Maintaining Sumps And Spill Buckets
Untitled Document Who Should Read This Manual? This manual is intended for owners and operators of underground storage tank (UST) systems; specifically, anyone who oversees the operation and maintenance of UST systems that contain and dispense petroleum products. UST owners/operators should ensure that only qualified personnel conduct inspection and ...

Material flow analysis and integration of watersheds and drain systems: II. Integration and solution strategies with application to ammonium management in Bahr El-Baqar drain system
The objective of this paper is to develop a systematic methodology for mass integration in drain systems and watersheds. Mass integration is a holistic approach to the tracking, transformation, and allocation of species and streams. The watershed and drain system is first discretized into reaches. The MFA model developed in part I of this work (Simulation and Application to Ammonium Management in ...

Interviewer Effects on the Valuation of Goods with Ethical and Environmental Attributes
This paper investigates the impact of interviewer effects on willingness to pay (WTP) estimates. Face-to-face surveys were conducted with two interviewers. Both interviewers used a transcript and conducted the survey at the same location and at the same time. We found that responses to the WTP questions differ across eco-labeled products and by interviewer. This interviewer effect is particularly ...

Accumulation and toxicity of monophenyl arsenicals in rat endothelial cells
Clark 1 (diphenylarsine chloride) and Clark 2 (diphenylarsine cyanide) were used as chemical weapon agents (CWA), and the soil contamination by these CWA and their degraded products, diphenyl and phenyl arsenicals, has been one of the most serious environmental issues. In a series of comparisons in toxicity between trivalent and pentavalent arsenicals we investigated differences in the ...

Sources of Nitrate in Snowmelt Discharge: Evidence From Water Chemistry and Stable Isotopes of Nitrate
To determine whether NO3−, concentration pulses in surface water in early spring snowmelt discharge are due to atmospheric NO3−,, we analyzed stream δ,15N-NO3−, and δ,18O-NO3−, values between February and June of 2001 and 2002 and compared them to those of throughfall, bulk precipitation, snow, and groundwater. Stream total Al, DOC and Si concentrations were used ...

Intraspecific Genetic Diversity of Undaria pinnatifida in Japan, based on the Mitochondrial cox3 Gene and the ITS1 of nrDNA
The intraspecific genetic diversity of the kelp Undaria pinnatifida (Harvey) Suringar (Laminariales, Phaeophyceae) was investigated using DNA sequences of the mitochondrial cytochrome oxidase subunit 3 (cox3) gene and internal transcribed spacer 1 (ITS1) of nuclear ribosomal DNA in plants collected from 21 localities along the Japanese coast between 2001 and 2003. Morphological variation was also ...

The use of the Pareto distribution for fracture transmissivity assessment
For many applications data on the transmissivity distribution of individual fractures are necessary, i.e., discrete fracture network (DFN) modelling of groundwater flow and transport of solutes in fractured rock and design and performance of rock grouting. Using borehole data from the Äspö Hard Rock Laboratory, Sweden, it is shown that evaluated fracture transmissivities from three boreholes at ...

Applicability of the most frequent value method in groundwater modeling
The Most Frequent Value Method (MFV) is applied to groundwater modeling as a robust and effective geostatistical method. The Most Frequent Value method is theoretically derived from the minimization of the information loss called the I-divergence. The MFV algorithm is then coupled with global optimization (Very Fast Simulated Annealing) to provide a powerful method for solving the inverse ...

Assessing selected natural and anthropogenic impacts on freshwater lens morphology on small barrier Islands: Dog Island and St. George Island, Florida, USA
The freshwater lens morphologies of the barrier islands Dog Island and St. George Island on the panhandle coast of Florida (FL), USA, are controlled to varying degrees by both natural and anthropogenic factors. Variable-density groundwater flow models confirm that spatial variability of recharge values can account for the observed lens asymmetry on these islands. The depth to the base of the lens ...

On the consideration of mesoscale transports in climate modelling
The dynamical effect of land surface heterogeneity on heat fluxes in the atmospheric boundary layer (ABL) is investigated using numerical simulations with a nonhydrostatic model over a wide range of grid resolutions. It is commonly assumed that mesoscale or dynamical fluxes associated with mesoscale and convective circulations simulated by a high-resolution model (subgrid (SG) model) on the ...

Per Capita Carbon Dioxide Emissions: Convergence or Divergence?
Understanding and considering the distribution of per capita carbon dioxide (CO2) emissions is important in designing international climate change proposals and incentives for participation. I evaluate historic international emissions distributions and forecast future distributions to assess whether per capita emissions have been converging or will converge. I find evidence of convergence among ...

Geostatistical Analysis for Hydrogeochemical Characterization of the Han River, Korea: Identification of Major Factors Governing Water Chemistry
The Han River is the largest river in South Korea in terms of its length, drainage and mean annual discharge. The river is of importance for cultural and economic reasos because it is a unique source of drinking water for more than 20 million people living in Seoul and its surrounding areas. Intensive industrial development in Seoul during the last four decades has greatly increased the risk for ...

Emission predictions with a multi-linear reservoir model
ABSTRACTFor the assessment of combined sewer overflows detailed models are not necessary. Physically based conceptual models give an optimal balance between model uncertainty and uncertainty in the input data. Besides, it is important that continuous long term simulations are performed. To prove this, in this paper the calibration of a reservoir model is discussed. The emission results of the ...
