“…This view is supported by Benmansour et al (2013) in a study conducted in Marchouch South East, Morocco. The findings reported that the net soil erosion rates were 14 t/ha/yr and 12 t/ha/yr when 137 Cs and 210 Pb were respectively used in assessing the soil redistribution in agricultural fields.…”

“…As a result, there is need to estimate the chronology of sediment production especially in most catchments within developing countries where the sedimentation rates of reservoirs are inadequately documented. Also, soil erosion rate data at different temporal changes is required so as to aid in quantifying potential changes that might occur when different land uses have been adopted and with change in climate (Li et al, 2010;Benmansour et al, 2013).…”

Soil erosion is one of the main soil degradation phenomena that threaten sustainable use of soil productivity thus affecting food security. In addition, it leads to reservoir storage capacity loss because of sedimentation. This not only affects water quantity but also water quality. Worldwide, annual loss in reservoir storage capacity due to sedimentation is 0.5 to 1%. Similarly, about 27% of land in Africa is largely degraded by erosion. As a result, there is need to minimize soil erosion and deposition through site specific estimation of soil erosion and deposition rates in the reservoirs. To achieve this, Fallout RadioNuclides (FRNs) are some of the methods in use. The most common radionuclides include; 137 Cs, 210 Pb and 7

Radioactive isotopes, both natural and artificial, present in the environment, may be convenient indicators that can be used to study many physical and chemical processes as well as the transport of pollutants in the ecosystem. The studies have shown that in identification of particulate matter emission sources a radioactive lead isotope (Pb-210) can be used. The Pb-210 increased activity concentration in the top soil layers suggests its current atmospheric deposition. This conclusion is confirmed by the results of the Principal Components Analysis, conducted using the measured radionuclide content in 0-30 cm deep soil layer samples. Keywords: Pb-210, pollutant emission indicator IntroductionRadioactivity is not only a source of human exposure, but it also has many practical applications. Using the properties of radioactive isotopes, it is possible, for example, to generate electricity, test materials, diagnose and treat people. Radioisotopes are also used in environmental studies [1].Radioactive isotopes are used, inter alia, to study the mechanisms and dynamics of the processes in soil and plants , to determine the age of rocks, minerals, sediments and soil (eg C-14, U-238, U-235 and Th-232), to study the circulation of elements and their radioactive isotopes in the food chain and in the monitoring studies (natural isotopes, eg K-40, U-238, or artificial isotopes, [1].The examples of monitoring studies include the assessment of the activity of caesium isotopes in surface soil in spatial terms [2][3][4][5].Radioactive isotopes are also used in laboratory testing of processes under controlled conditions, which makes it possible to describe them and to assess the behavior in the environment. The use of these methods is presented, inter alia, in sample Australian studies 1 Independent Chair of Biotechnology and Molecular Biology, Opole University, ul. kard. B.

The use of Cs-134, Sr-85 and Zn-65 made it possible to determine the penetration of radioactive fallout into tropical soil. were used to identify the mechanism and dynamics of trace metal bonding in port sediments.Radioactive isotopes present in the environment, such as Th-234, Be-7, Pb-210, Cs-137, Si-32 and C-14, were used to study present-day sedimentation in seas and oceans. Th-234 and Be-7 isotopes are used, inter alia, in bioturbation and sedimentation studies in the high material supply conditions [7,8].Pb-210 isotope is most commonly used to determine the rate of marine [9] and lacustrine [10-14] sediment increase, but also to identify the rate of snow cover increase. The lead method was also used in Alpine glacier studies [15,16].Cs-137 is used, as a time marker, very often together with Pb-210, to determine the age of lacustrine sediments. The literature review shows that Cs-137 may be used to determine the rate of deposition of overbank [17,18], lacustrine and delta [19,...

“…To accomplish this, research has traditionally used single component signatures encompassing mineralogy (Klages andHsieh 1975, Wood 1978), colour (Grimshaw andLewin 1980, Carreras et al 2010), mineral magnetic (Bonnet et al 1989, Walden et al 1997, Hatfield and Maher 2009, Wang et al 2011, fallout radionuclides (Loughran et al 1992, Walling and Woodward 1992, Olley et al 1993, Wallbrink et al 1998, Zapata 2003, Mabit et al 2008, Shi et al 2011, Yan et al 2012, Benmansour et al 2013) and organic matter (Santiago et al 1992) properties. However, using single property or component signatures is likely to prove unrealistic and result in spurious linkages between source materials and sediment (Collins and Walling 2002), so most fingerprinting studies now employ composite fingerprints, which comprise a range of different diagnostic properties influenced by contrasting environmental controls, and thereby greatly improve the reliability of sediment source discrimination (Walling et al 2006).…”

Soil erosion and eroded sediment are serious threats to sound land management. However, less attention has been given to quantifying the importance of different soil erosion features based on appropriate control measures that could be designated. Accordingly, this research was planned to quantify the contribution of potential sediment sources, i.e. sheet, rill and gully erosion, in Idelo watershed in Zanjan Province, Iran, using composite fingerprinting. Toward this aim, 16 geochemical and organic tracers were detected in sediment sources and sediment deposited at the outlet. The results of applying the composite fingerprinting technique, with a relative error of 16%, showed that sheet, rill and gully sources contributed 56%, 44% and 0%, respectively, to sediment yield. It was also apparent from the results that the composite fingerprinting approach could be successfully utilized to assess the provenance of sediment deposited at the main outlet of the study watershed by soil erosion type.Key words composite fingerprinting; geochemical properties; sediment source discrimination; sediment yield; Idelo watershed, Iran Attribution de types d'érosion des sols pour la production de sédiments en utilisant la technique des empreintes composites Résumé L'érosion des sols et les sédiments érodés représentent de sérieuses menaces pour la bonne gestion des terres. Cependant, la quantification de l'importance des différentes caractéristiques de l'érosion des sols sur la base de mesures de contrôle appropriées qui pourraient être identifiées, a reçu une attention limitée. En conséquence, la présente recherche a eu pour objectif de quantifier la contribution des sources potentielles de sédiments, c'est-à-dire l'érosion en nappe, rigoles et ravines, dans le bassin versant de l'Idelo dans la province de Zanjan (Iran), à l'aide d'empreintes composites. A cette fin, 16 traceurs géochimiques et biologiques ont été détectés dans les sources de sédiments et les sédiments déposés à l'exutoire. Les résultats de l'application de la technique des empreintes composites, avec une erreur relative de 16%, ont montré que les sources de nappes, rigoles et ravines ont contribué respectivement à hauteur de 56%, 44% et 0%, au rendement sédimentaire. Les résultats ont également permis de comprendre que l'approche par empreintes composites pourrait être utilisée avec succès pour évaluer la provenance par type d'érosion des sols des sédiments déposés à l'exutoire principal du bassin versant d'étude.
