Results obtained in terms of burden exerted on four relevant environmental impact categories, are reported in Table 1.
Furthermore, in this case, for example, the burden exerted by the safety barrier on the EP is remarkably higher than the one exerted by the pavement (three times higher).
The life cycle assessment (LCA) approach [10, 11] is well acknowledged as one of the most effective tools for correctly assessing the potential burden exerted on the environment by road infrastructures and transportation systems.
These impact categories, i.e., global warming potential (GWP), POCP, acidification potential (AP), and eutrophication potential (EP), allow to estimate and compare the burden exerted by each component of a road.
The use of recycled and innovative materials has also received an increasing attention due to their capability of limiting the environmental burden exerted by infrastructures equipped with them: the use of secondary materials, in fact, avoids the recourse to virgin materials and therefore prevents their depletion.
In any case, the assessment of the burden exerted by roads on the natural environment needs more comprehensive perspectives that range from climate change analyses [6] to ecosystem preservation [7], with a new attention to the sustainability footprint impacts [8, 9].
Despite there being a higher rebound effect for higher IPTi coverage, the largely lowered burden exerted on the first year of age renders these interventions more effective against clinical malaria.
The A/H1N1 2009 disease burden exerted a substantial impact on the operational capacities of local health care systems.
To assess the inflammatory burden exerted by the periodontium, the periodontal inflamed surface area (PISA) [ 35] was quantified.
