TL;DR: An analysis of the site restoration techniques that may be employed in a variety of contaminated site cleanup programs and the important parameters that will help in the selection and implementation of one or more appropriate technologies in a defined set of site and contaminant characteristics.

TL;DR: A broad range of sophistication/complication in terms of the methods applied in assessing and mapping benthic habitats was found, including the simplest index or metric involved some assessment of species richness, while the most complicated required utilizing multi-variate analysis.

TL;DR: The performance of an anaerobic digestion process is much dependent on the type and the composition of the material to be digested, and when the fraction of starch-rich waste was increased, the result was a more sensitive process, with process overload occurring at a lower organic loading rate (OLR).

TL;DR: The results point to the effectiveness of the Neem leaf powder as a biosorbent for removing dyes like Congo Red from water.

TL;DR: Reviewing the provincial, territorial, and state guidelines for the retention of treed riparian buffers after timber harvest in Canada and the United States found buffer widths were adequate to protect the aquatic biota and habitats but were, generally, less than recommended widths for terrestrial communities.

TL;DR: This special issue documents developments in analysing the system properties in a biophysical and socio-economic context at multiple scales and integrating spatially explicit land use change models in integrated assessment models, as well as modelling of the actual decision making process with agent-based modelling.

TL;DR: This manuscript reviews several source tracking methodologies which are in current use for source tracking fecal bacteria in the environment including: ribotyping, pulse-field gel electrophoresis, denaturing-gradient gel electrospecies, repetitive DNA sequences (Rep-PCR), host-specific 16S rDNA genetic markers, and antibiotic resistance analysis.

TL;DR: An analysis of how scale issues affect an agent-based model (ABM) of landcover change developed for a research area in the Midwest, USA and results show that the distribution of landuse-preference weights differs as a function of scale.

TL;DR: Results of kinetic experiments indicated that HiSiv 1000 had the highest rate of adsorption among the adsorbents studied and therefore more detailed studies were carried out with this adsorbent.

TL;DR: Since Zn is the most serious water pollutant and wood shingle is the worst of the four roof types, using less compounds and materials associated with Zn along with good care and maintenance of roofs are critical in reducing Zn pollution in roof runoff.

TL;DR: The lowest effluent nutrient levels were realized by using the five-step operation which resulted in effluent COD, NH4-N and PO4-P contents of 1,400, 107 and 65 mg l(-1), respectively, at the end of 21 h.

TL;DR: An overriding importance of urban land cover expansion is revealed in the changes in heat island intensity and surface temperature patterns as well as the combined use of satellite-derived vegetation and land cover distributions with land surface temperature maps.

TL;DR: An approach to modelling land use change that links model selection and multi-model inference with empirical models and GIS is developed, illustrated with a case study of rural housing as it has developed for part of Gallatin County, Montana, USA.

TL;DR: This review examines the most important groups of chemicals that must be treated at sites contaminated by explosives processing, the chemical and biological transformations they undergo, and commercial processes developed to exploit these transformations for treatment of contaminated soil.

TL;DR: The study shows that the Analytic Hierarchy Process can explicitly incorporate stakeholder preferences and multiple objectives to evaluate management options and provides several approaches for policy makers to arrive at policy decisions.

TL;DR: The results were comparable with those obtained by the application of conventional coagulants such as alum or polyaluminum chloride; therefore, bioflocculant can be considered as a viable alternative in the treatment of landfill leachates applying coagulation.

TL;DR: The process through which climate change scenarios were downscaled in an urban land use model and the results of this experimentation are described and the spectrum of possible land use/land cover change scenarios for the years 2020 and 2050 are illustrated.

TL;DR: This paper ascribes the limited achievement of national sustainability assessment in Malaysia to four types of constraints: meta-policy issues; technical capacities; communication concerns; and the inherent knowledge gaps within the indicator developer community vis-a-vis their theoretical limitations.

TL;DR: A new indexing method using fuzzy synthetic evaluation is proposed to determine the health risk associated with the two major groups of chlorinated DBPs--trihalomethanes (THMs) and haloacetic acids (HAAs).

TL;DR: The potential and limitations of the MAS are discussed to build models that enable spatial planners to include the 'actor factor' in their analysis and design of spatial scenarios.

TL;DR: An integral approach for treatment of aqueous process streams in the textile finishing industry is proposed, and a simulation for a 500 m3/d production unit shows that it is feasible, although modifications may be necessary depending on the nature of the finishing baths.

TL;DR: The role of ICT is analyzed in developing a system for environmental collaborative monitoring intending to promote the use of volunteer collected data and a collaborative system that allows the public to express its knowledge on the state of the environment is described.

TL;DR: This paper is an attempt to summarize existing knowledge on the importance of woody plants in savanna and explore measures, based on ecosystem dynamics, which can be utilized to restore encroached areas more successfully.

TL;DR: A decision support system is proposed that can provide information on the environmental impact of anthropic activities by examining their effects on groundwater quality using the combined value of both intrinsic vulnerability of a specific local aquifer and a degree of hazard value, which takes into account specific human activities.

TL;DR: Survey design features of the CV study, especially an unfamiliar sub-group of endangered species, could explain the apparent insensitivity to scope observed and imply that CV is not a theoretically valid method for biodiversity valuation.

TL;DR: The presented model highlights dimensions requiring attention by those working within co-operative environmental management, and is valuable as it reflects the complexity and range of such arrangements in practice.

TL;DR: Both materials, HAP and CA, can be used for heavy metal retention and the former has better performance for water treatment due to its greater efficiency for the retention of Cd, Zn and Co and its lower solubility in a wide range of pH.

TL;DR: The observed landscape changes at the farm level show a low, but structured relationship with the current farm and farmer characteristics, meaning that landscape changes were undertaken by various farmers and on various farms.

TL;DR: Preliminary screening of the proposed beneficial use alternatives identified advantages, disadvantages, potential volumes, and estimated costs associated with each project type.

TL;DR: Data analysis based on logistic regression indicates that water quality variations and geographic location in the distribution system have a significant impact on the consumer perception, and appears to be strongly associated with residual chlorine levels.
