As much as 60% of the nitrate in water in England is thought to derive from agriculture. Legislation aims to improve water quality by limiting nitrate concentration in surface and groundwaters to 50 mg l−1. The UK Government responded to the requirements of the EC Nitrate Directive by delineating Nitrate Vulnerable Zones (NVZs) to cover 55% of England in 2002 and increased it to 70% in 2009. In this study we assessed the cost-effectiveness of measures for implementation in livestock systems to mitigate nitrate leaching in the UK. These estimates were prepared for a range of hypothetical farms representative of typical dairy, beef and sheep farms at different locations in England and Wales and for a list of mitigation measures identified to reduce leaching. The NGAUGE and NFixCycle models were used to estimate leaching from these systems. The costs of implementation of the mitigation measures were also assessed in order to evaluate the cost-effectiveness of these measures. In general, the most effective measures to reduce leaching for all systems were the ones that involved a reduction in stocking rates and grazing time, followed by those involving improvements in fertiliser and crop management. Only in the case of the dairy system was effectiveness affected by location of the farm. The costs for implementation in the sheep system were relatively low compared with beef and dairy systems. Implementation of some of the measures with high cost-effectiveness would need to be incentivised financially or with legislation due to the high costs involved.  相似文献

Use of iodide to enhance the phytoextraction of mercury-contaminated soil   总被引:1,自引:0,他引:1  
Low bioavailability of mercury (Hg) in soil is a restricting factor in phytoextraction of Hg-contaminated soil. Iodide is known to mobilize Hg in soil and, therefore, the aim of this study was to investigate the possibility to use iodide to increase phytoextraction of Hg. The sensitivity of willow to iodide was investigated in both hydroponics with 0-10 mM KI and in soil with 0.2 and 1 mM KI addition. The capacity to accumulate HgI(2) was compared with that of Hg(NO(3))(2) in hydroponics. Soil extractions with 0-2 mM KI were used to study mobilization of Hg in aged Hg-spiked soil. Additions of KI (0.2-1 mM) were used in pot tests with aged Hg-spiked soil as well as in field trials in an industrial Hg-contaminated soil to study whether iodide addition increased the accumulation of Hg from contaminated soil and the translocation of Hg to the shoots. The total Hg contents in plants, soils and extracts were analyzed by CVAAS. The results showed that too high KI concentration was toxic to plants. Moreover, KI was toxic to plants at lower concentrations in hydroponics than in soil additions. KI (85 microM) in hydroponics gave 50% growth decrease in terms of dry weight of shoot biomass, whereas 0.2 mM KI in soil addition could be tolerated by the plant without growth disturbance. Willow accumulated Hg from HgI(2) solution slower than that from Hg(NO(3))(2) solution. KI mobilized Hg in contaminated soil and thereby increased the bioavailability of Hg in soil. Up to 1 mM KI addition increased the Hg concentrations to about 5, 3 and 8 times, respectively, in the leaves, branches and roots. However, the Hg translocation to the shoots did not show an increase with KI addition. Only less than 1% of the total Hg accumulated in the plant was distributed in the shoots. We may conclude that iodide addition enhances the phytoextraction of Hg, however, the translocation of Hg to the shoots is still too low and therefore it will not be realistic to use this method for phytoextraction of Hg-contaminated soil in practice.  相似文献

As people spend most of their time in an indoor environment, it is important to predict indoor pollutant level in order to assess health risks. As particles are an important pollutant indoors, it is of great interest to study the airflow pattern and particle dispersion in buildings. This study uses large eddy simulation (LES) to predict three-dimensional and transient turbulent flows and a Lagrangian model to compute particle trajectories in a room. The motion of three different types of solid particles in a decaying homogeneous isotropic turbulent airflow is calculated. By comparing the computed results with the experimental data from the literature, the computational method used in this investigation is found to be successful in predicting the airflow and particle trajectories in terms of the second-order statistics, such as the mean-square displacement and turbulent intensity. This Lagrangian model is then applied to the study of particles' dispersion in a ventilated cavity with a simplified geometry for two ventilation scenarios. It is shown that light particles follow the airflow in the room and many particles are exhausted, while heavier particles deposit to the floor or/and are exhausted. PRACTICAL IMPLICATIONS: The results of this paper can be used to study dispersion of infectious diseases in enclosed spaces in which virus or bacteria are often attached to particles and transported to different rooms in a building through ventilation systems. In most of studies, the virus or bacteria have been considered to be gaseous phase so there is no slip between virus/bacteria and air. The results in this paper show that heavier particles are submitted to gravity and are sensitive to the ventilation strategy.  相似文献

Public health and economic impact of dampness and mold   总被引:1,自引:0,他引:1  
Mudarri D  Fisk WJ 《Indoor air》2007,17(3):226-235
The public health risk and economic impact of dampness and mold exposures was assessed using current asthma as a health endpoint. Individual risk of current asthma from exposure to dampness and mold in homes from W.J. Fisk, Q. Lei-Gomez & M.J. Mendell [(2007) Indoor Air, [corrected] 17, 284-296], and [corrected] asthma risks calculated from additional studies that reported the prevalence of dampness and mold in homes were used to estimate the proportion of US current asthma cases that are attributable to dampness and mold exposure at 21% (95% confidence internal 12-29%). An examination of the literature covering dampness and mold in schools, offices, and institutional buildings, which is summarized in the Appendix, suggests that risks from exposure in these buildings are similar to risks from exposures in homes. Of the 21.8 million people reported to have asthma in the USA, approximately 4.6 (2.7-6.3) million cases are estimated to be attributable to dampness and mold exposure in the home. Estimates of the national cost of asthma from two prior studies were updated to 2004 and used to estimate the economic impact of dampness and mold exposures. By applying the attributable fraction to the updated national annual cost of asthma, the national annual cost of asthma that is attributable to dampness and mold exposure in the home is estimated to be $3.5 billion ($2.1-4.8 billion). Analysis indicates that exposure to dampness and mold in buildings poses significant public health and economic risks in the USA. These findings are compatible with public policies and programs that help control moisture and mold in buildings. PRACTICAL IMPLICATIONS: There is a need to control moisture in both new and existing construction because of the significant health consequences that can result from dampness and mold. This paper demonstrates that dampness and mold in buildings is a significant public health problem with substantial economic impact.  相似文献

A vision of change for innovation within the perspective of revaluing the construction industry is essential to develop a culture of self-sustaining improvement, mutual recognition, respect and support in the long term in North Cyprus. The research attempts to put forward a case for a restructuring of the construction sector in order to deliver a step in change in quality of output and to realise maximum value to all clients, stakeholders and end users. The main objective of this study is to (1) determine current innovation practices and identify key issues that contribute to successful implementation (2) assess the existence and severity of barriers to change for innovation (3) propose solutions for overcoming barriers to change for innovation in construction industry and develop a framework to revaluate the construction industry. The research includes an extensive literature study, interviews with managers on the challenge of change for innovation in construction, analysis of this information to develop findings, and extending these to present the key strategic issues that could be targeted for revaluing the construction industry. The paper commences on understanding the firms’ own processes and detecting their weaknesses and strengths, determining the strategies and actions that should be made in the short term to adopt innovation practices and helping the North Cyprus construction industry to learn as a whole. The paper concludes how the drivers of change for innovation can offer benefits to construction firms in North Cyprus if appropriate strategies are adopted.  相似文献

Nearshore marine environments of industrialized countries are increasingly threatened by anthropogenic pollution. It is therefore a priority task to investigate the sensitivity of new ecotoxicological warning signals of the occurrence and effects of aquatic pollutants. The main aims of the present study were: 1) to characterize the biochemical properties of ChEs in tissues of the bivalve Pecten jacobaeus, using different specific substrates and selective inhibitors; 2) to measure sensitivity of ChE activities to in vitro exposure to the OPs azamethiphos and DFP and to the heavy metals cadmium and zinc. Our final aim was to carry out a preliminary evaluation of the suitability of ChEs measurement in tissues of the scallop for monitoring marine environmental quality and neurotoxic compounds contamination in the Mediterranean Sea. Responses to specific inhibitors have suggested that ChEs in adductor muscle share many characteristics with vertebrate acetylcholinesterase. Dose-dependent inhibition of ChE was observed in response to in vitro exposure to environmental contaminants such as cadmium and azamethiphos. Sensitivity to zinc and DFP was lower. ChEs in P. jacobaeus might therefore have potential as a sensitive biomarker for monitoring marine pollution. Results of the present study will be useful to focus further experiment of exposure to pollutants under in vivo conditions. CAPSULE: Cholinesterase activities in scallop Pecten jacobaeus were observed to be sensitive to contaminants in vitro and may therefore have potential as biomarkers for monitoring water pollution.  相似文献

ABSTRACT

The articles in this special issue demonstrate how objects can be interpreted as agents, as gendered images that make a statement, and how their impacts can be understood and assessed by human actors. They are differentially placed in matrices of power, and they can be manipulated to shift genders, to play with gendered combinations, to expand the limits of a particular gendered domain, to creatively play with reproductive imagery, and even to sell commodities in new and enticing ways in the mass media. Gendered religious objects are “statements” addressed not only to the eye but to the emotions, and part of a complex cultural field in which things can play important roles in people's lives. The links that connect ritual power to other forms of agency and biographical significance are perhaps the most significant links that we need to examine to understand them better in a world of many diverse cultural forms.  相似文献

Devolution in the United Kingdom has involved the creation of different quasi-autonomous political administrations. As part of an attempt to encourage institutional learning, there has been a turn to concordats to facilitate cooperation on matters of shared concern, to communicate appropriately and in a timely way, to work in a helpful and open manner and to treat information in confidence. In parallel, the reform of statutory land-use planning systems in the devolved United Kingdom has involved debates around the need for a cultural change to implement a relatively more positive model of planning and development amongst the diversity of stakeholders which have similarly invoked new forms of public diplomacy. The Edinburgh Planning Concordat sets out in some detail the agreed step-by-step actions to be effected and the respective responsibilities of the local authority and developers at the different stages in the land-use planning process. Such anticipated cooperation and coordination in the land-use planning and property development community could suggest a stronger basis for decision making and the articulation of the public interest. Locating the discussion against the backdrop of devolution and planning reform in Scotland, and within theories of new contractualism, this article examines the rise of ‘soft’ forms of public diplomacy as a means to facilitate cultural change and planning reform.  相似文献
