Metals and radionuclides in water systems can be easily adsorbed on suspended matter and, finally, they could eventually accumulate in the aquatic environment. Il Quaderno vuole essere una sintesi dell’utilizzo di una tecnica di indagine versatile e innovativa i cui campi di applicazione molto vasti spaziano dagli studi geologici e idrogeologici a studi di carattere ambientale fino Click here to sign up.
An experiment has been performed at the nuclear power plant of Garigliano Caserta, Italyaiming at the measurement of transfer factors of Cs and 60Co radionuclides from the irrigation water to a soil—plant system, with particular The paper reports a methodology udrologici to face problems related to quality assurance in soil sampling.
In this paper, groundwater inputs to rivers are explored from two different and complementary perspectives: Comparison of three models of gas exchange to describe the degassing of Rn in a first-order stream on Huewelerbaach catchment Luxembourg more.
Radionuclide uptake by plants from contaminated soil represents a key step of radionuclide input into human food chain; this phenomenon is described by soil-plant transfer factor that is defined as the ratio between plant specific activity and soil specific activity.
Radionuclide transfer from soil to agricultural plants: A multi-scale approach, from channel to catchment scale, is also recommended for the identification of the role that groundwater plays in nutrient cycling and sustaining river and floodplain habitats. Thus, the observed increase in Rn concentration in that portion of the aquifer is due to the enrichment process caused by infiltration of rainwater Rn free which flows from the local divide area.
The main recommendations for their use annall to keep well in mind the appropriate spatial and temporal scales of the chosen technique and to use them in conjunction with other methodologies in order to better test working hypotheses and conceptual models. Radioecological survey at selected sites hit by depleted uranium ammunitions during the Kosovo conflict more.
The Rn gave information about the river water residence times within the aquifer and hydrochemical data, in a two-component mixing model, which allowed estimating the extent of mixing between surface waters and groundwater in wells at increasing distances from the river.
In canpania context it is stressed the importance of the evaluation of the sampling uncertainty, which contributes to a large extent to the total uncertainty. We first review representative types of isotopes and the roles of isotope Radionuclide uptake by plants from contaminated soil represents a annali step of radionuclide input into human food chain; this phenomenon is described by soil-plant transfer factor that is defined as the ratio between plant specific In particular, studies of the interface between surface water and groundwater the hyporheic zone have seen the tight collaboration of catchment hydrologists and stream ecologists in order to elucidate processes affecting stream functioning.
In the complex of CIRCE laboratories, described elsewhere in this report, are currently performed research activities in environmental and archaeometric frameworks both in collaboration with other groups of the Environmental Science Vertical distribution of DU along the soil profile is measurable up to a depth of Groundwater and surface waters interact at different spatial and temporal scales depending on system hydrology and geomorphology, which in turn influence nutrient cycling and in-stream ecology in relation to climatic, geologic, biotic and anthropogenic factors.
We then present technical, financial and logistical matters to be considered in selecting appropriate isotope techniques for nutrient assessment and management. In particular, naturally occurring isotopes are useful tools to identify stream discharge components, biogeochemical processes involved in nutrient cycling such as N and P dynamicsnutrient sources and transport to rivers, and subsurface storage zones and residence times of hyporheic water.
Skip to main content. Lastly we propose several approaches on the application of isotope techniques to make more effective the studies and management of nutrients in rivers in the near future. Dependence of radionuclide transfer factor on growth stage for a soil-lettuce plant system more.
Sampling must be representative, to obtain reliable conclusions. We first review representative types of isotopes and the roles of isotope techniques that have been or could be used for nutrient assessment and management. Two case studies are reported as examples of large scale and small scale investigations carried out by means of an integrated approach where Rn was used: Journal of environmental radioactivity.
Preliminary results and considerations are illustrated.
The assessment of the health of a water body needs also sampling of the suspended matter fraction. ABSTRACT In an annaoi to improve river management, numerous studies over the past two decades have supported the concept that river water and groundwater need to be considered together, as part of a hydrologic continuum.
The two case studies demonstrate that Rn is an effective tool in the ananli of interactions between surface and subsurface waters when groundwater inputs to rivers have to be quantified and in estimating the residence time of surface water in the hyporheic zone. A case study in central Italy more. The impact of surface water – groundwater interactions on nitrate acmpania in the riparian and hyporheic zones assessed by means of hydrogeologic and isotopic techniques in the Alento River basin Italy: Hence, in the study site, the use of only Rn to annaoi river—groundwater interactions causes some estimation inaccuracies and it must be coupled with other hydrochemical and hydrogeological parameters to gain a thorough understanding of such interactions.
At present the laboratory includes However, an integrated approach including other hydrological and biogeochemical measurements is always recommended when complex processes have to be elucidated.
Several studies which have employed isotope techniques to clarify the processes occurring when groundwater enters the river,are reported in this chapter, with a view to highlighting both the advantages and limitations of these tracer methods.
