Subsurface flows, particularly hyporheic exchange fluxes, driven by streambed topography, permeability, channel gradient and dynamic flow conditions provide prominent ecological services such as nitrate removal from streams aquifers. Stream dynamics cause strongly nonlinear often episodic contributions of nutrient concentrations in river-aquifer systems. Using a fully coupled transient reactive...

Climate change is one of the greatest global challenges and Pacific island countries are particularly vulnerable due to, among other factors, their geography, demography and level of economic development. A Health Impact Assessment (HIA) framework was used as a basis for the consideration of the potential health impacts of changes in the climate on the population of Vanuatu, to assess the risks...

by increasing crops yield due to intensive use of agricultural machinery and energy inputs, utilizedenergy in agriculture has been increasing rapidly which negative environmental impacts on water,air and soil are its consequences. in this paper, potato production in isfahan province was studiedusing life cycle assessment approach from the standpoint of energy consumption and environmentalimpact...

This paper aims to examine the attitudes of the consumers in Greece towards the use of biotechnology in forest plantations and their potential purchases of forest transgenic products. Three groups of factors related the consumers’ attitude on the use of biotechnology in forest plantations with the potential purchases of transgenic forest products: (a) the potential negative environmental impact...

The environmental issues of possible concern during construction and operation of desalination plants (mainly large-scale facilities) include impacts that are common to many coastal development projects (e.g. land use and aesthetic impacts), as well as specific impacts associated with the elements of the desalination system and auxiliary infrastructure. In the latter category these relate to th...

Strategies for sampling shallow soils at hazardous waste sites are employed primarily to evaluate levels and distributions of contamination. The ensuing analyses of potential public health impacts are therefore dependent on the sampling design rather than having the sampling design based on the data needs for evaluating potential public health impacts of shallow soil contamination. We define a ...

Prospective studies of the potential health consequences of trade and investment treaties, such as the Trans-Pacific Partnership, are critical. These studies can make visible to trade policy-makers the potential negative impacts associated to such treaties and can influence the outcomes of such negotiations. However, few researchers have examined retrospectively the consequences of trade agreem...
