Journal ArticleDOI
TL;DR: Some novel pre-hydrolysed coagulants such as Polyaluminium chloride (PACl), Polyal aluminium ferric chloride (PAFCl), Polyferrous sulphate (PFS) and Polyferic chloride (PFCl) have been found to be more effective and suggested for decolourisation of the textile wastewater.

Journal ArticleDOI
TL;DR: The conversion of waste products into effective adsorbents and their application for water treatment and the possible mechanism of adsorption on these adsorbent has been included in this article.

1,080 citations


Journal ArticleDOI
TL;DR: A comprehensive review of wetland structures, classic and novel nitrogen and organics removal mechanisms along with the key environmental parameters and operational conditions that enhance removal in subsurface flow wetland systems shows the necessity of a profound knowledge on the complicated inter-relationship between nitrogen and Organics removal routes, governing environmental and operational parameters, and wetland matrix for improving the treatment performances of subsurfaced flow wetlands.

747 citations


Journal ArticleDOI
TL;DR: The regulatory structure governing the environmental endpoints of BPA in the United States, European Union, and Canada is critically examined, and major challenges to the effective regulation are discussed.

693 citations


Journal ArticleDOI
TL;DR: It is shown that various approaches to data collection affect the results and comparability of adoption studies, and environmental awareness and farmer attitudes have been inconsistently used and measured across the literature.

656 citations


Journal ArticleDOI
TL;DR: The results show that organic farming practices generally have positive impacts on the environment per unit of area, but not necessarily per product unit, and that conventional farming systems have lower environmental impacts than organic systems.

618 citations


Journal ArticleDOI
TL;DR: The paper describes the main reactors used, the influence of the main operating variables, the microorganisms or reagents employed and the characterizations of the final effluent principally in terms of chemical oxygen demand and the comparison between the different treatment alternatives is postulated.

Journal ArticleDOI

TL;DR: The results showed that the dynamic of coordination between urbanization and the environment showed a U-shaped curve, and both sub-systems evolved into a superior balance during rapid urbanization, indicating that socialurbanization and environmental control make the greatest contribution to the coupling system.

529 citations


Journal ArticleDOI
TL;DR: The present review aims to give an updated version of information available with respect to metal tolerance and accumulation mechanisms in plants, as well as on the environmental and genetic factors affecting heavy metal uptake.

486 citations


Journal ArticleDOI
TL;DR: The present batch adsorption study describes the effects of solution pH, biochar dose, and contact time on copper and cadmium removal efficiency from single metal ion aqueous solutions.

459 citations


Journal ArticleDOI
TL;DR: The role of AC is reviewed, the feasibility of each AC-amended decolourisation technique is evaluated, and perspectives on future research are discussed.

Journal ArticleDOI
TL;DR: This paper proposes a comprehensive framework to implement stakeholder participation in environmental projects, from stakeholder identification to evaluation, and establishes methods to determine who should participate, when and how.

Journal ArticleDOI
TL;DR: The limitations and environmental impact of existing cleanup methods are reviewed, and guidelines for the development of a new technology for the Middle East are proposed, which is the use of an abundant resource--date palm fibers--for such techniques.

Journal ArticleDOI
TL;DR: The optimum Cu(II) adsorption conditions was found to occur at 5-12 g/L adsorbent dose, initial pH 5-6, and reaction time 2-4 h, while the adsorptive kinetics were best described by the pseudo-second order model for all the tested materials.

Journal ArticleDOI
TL;DR: The UV-A/TiO(2) photocatalytic decomposition of amoxicillin (AMX) in aqueous suspensions was investigated and mineralization was slower than degradation due to the formation of stable transformation by-products.

Journal ArticleDOI
TL;DR: An overview of recent trends in wastewater management is proposed concerning the role of centralisation and decentralisation in wastewater treatment, and none of the approaches could be excluded a priori, but were generally shown to integrate one another on the basis of the specific required situation.

Journal ArticleDOI
TL;DR: It is found that the percentage of cropland in a given region correlates positively with nitrate concentration in groundwater, and the Gross Nitrogen Balance predicts nitrate contamination in groundwater more precisely in regions with higher average precipitation.

Journal ArticleDOI
TL;DR: The study of the long-term effects was carried out in lab-scale Sequencing Batch Reactors inoculated with the biofilm biomass and a total restoration of the SAA was observed after the stoichiometric feeding was applied to the SBR.

Journal ArticleDOI
TL;DR: This article describes the most recent methods developed to remove phthalic acid esters from water, wastewater, sludge, and soil, as well as their effects on human health and the environment.

Journal ArticleDOI
TL;DR: It is argued that planning practice needs to re-examine the impact of vegetation cover in the urban fabric given the evaluation of vegetation's effects on air quality, including the dispersion of traffic-induced particles at street level using the three-dimensional microclimate model ENVI-met®,.

Journal ArticleDOI
TL;DR: The test results indicate that the sugarcane bagasse ash waste could be used as a filler in clay bricks, thus enhancing the possibility of its reuse in a safe and sustainable way.

Journal ArticleDOI
TL;DR: The managers of urban spaces should direct their efforts to obtaining greater knowledge of people's attitudes, beliefs and pro-environmental values given their importance in their decisions regarding economic valuation of this sort of resources.

Journal ArticleDOI
TL;DR: There is an emerging consensus that processes that support social learning involve sustained interaction between stakeholders, on-going deliberation and the sharing of knowledge in a trusting environment.

Journal ArticleDOI
TL;DR: The paper reports on a 2009 survey of 21 research projects within the UK Research Councils' Rural Economy and Land Use Programme regarding the involvement and perceived impact of over a thousand stakeholders in the research.

Journal ArticleDOI
TL;DR: It is shown that it is difficult to select the mostappropriate wastewater treatment alternative under the "no scenario" condition, and the decision-making methodology presented in this paper effectively identifies the most appropriate wastewater treatmentAlternative for each of the scenarios.

Journal ArticleDOI
TL;DR: It is argued that as a result of path dependency, major changes in farming practice primarily occur in response to 'trigger events', after which farm managers intensify their consideration of the options open to them, and may set a new course of action.

Journal ArticleDOI
TL;DR: The collaboration of all relevant stakeholders and regulators to support changes to current regulatory frameworks to enable this, is proposed as the way forward, particularly as their complexity has been identified as the major hurdle to the implementation of co-digestion in the UK.

Journal ArticleDOI
TL;DR: The aim of this study is to analyze the relationship among groundwater productivity data including specific capacity (SPC) and transmissivity (T) as well as its related hydrogeological factors in a bedrock aquifer, and subsequently to produce the regional groundwater productivity potential (GPP) map for the area around Pohang City, Korea using a geographic information system (GIS) and a weights-of-evidence (WOE) model.

Journal ArticleDOI
TL;DR: By systematically examining the methodological decisions that must be made by the analyst at each stage of the assessment process, this paper aims to improve analysts' understanding of the relationship between MCDA theory and practice, and enable them to apply methods that are consistent with a decision maker's needs in any given problem context.

Journal ArticleDOI
TL;DR: This work recognizes green roofs as dynamic ecosystems and employs a diversity of species, and draws links between the ecological and green roof literature to generate testable predictions about how increasing plant diversity could improve short- and long-term green roof functioning.
