“…Recent layers have monitored a rapid increase in the accumulation rate to reach a value of 3.43 ± 0.55 (3.78 ± 0.57) kg m -2 y -1 with an average of 1.71 ± 0.27 (1.59 ± 0.26) kg m -2 y -1 for Q1 (Q2). These values of accumulation rates can be compared with recent studies (Begy et al, 2011;Gu et al, 2011;Sabaris and Bonotto, 2011;Gharibreza et al, 2013). Also the increase of the accumulation rate in the newer layers has been observed.…”

“…Also the increase of the accumulation rate in the newer layers has been observed. For example, in the work of Gharibreza et al (2013) pre-1950 sediment accumulation rate was found to be about 0.6 ± 0.2 kg m -2 y -1 , and it increased to 2.0 ± 1.0 kg m -2 y -1 in recent layers. This change could be related to the increasing of population, human and industrial activities in this area.…”

“…The 210 Pb method is widely used to characterize sediments on relatively short time scale (<150 years) (Evans and Rigler, 1980;Appleby, 2008;Kamman and Engstrom, 2002;Battarbee et al, 1985;Turner and Delorme, 1996;Begy et al, 2011;Gu et al, 2011;Sabaris and Bonotto, 2011;Gharibreza et al, 2013). 210 Pb, having a half life time of 22.3 years, is a member of the 238 U series that is distributed fairly uniformly across the Earth.…”

Sedimentation rates in the Lake Qattinah using 210Pb and 137Cs as geochronometer

Abstract:The constant rate of supply (CRS) of excess 210 Pb model was successfully applied to assess 210 Pb data of two sediment cores from the lake Qattinah, Syria. Gamma spectrometry was used to determine 137 Cs and 210 Pb activity concentrations. The bottom of the cores was 210 Pb-dated to years 1907 and 1893. The accumulation rates were determined using 210 Pb method and found to vary similarly in both cores from 0.10 ± 0.01 to 3.78 ± 0.57 kg m -2 y -1 during the past century. 137 Cs was used as an independent chronometer. The two distinct peaks observed on the 137 Cs record of both cores, corresponding to 1965 and 1986, have allowed a successful validation of the CRS model.

“…Lately, the heavy metal's accumulation in various vegetal (e.g., aquatic plant species) and animal organisms (e.g., sh tissue) have been largely investigated in many parts of the world [6,7]. The concentrations of heavy metals in aquatic environments (e.g., water and sediments) can be used as indicators regarding the food chain magni cation, the ecological background and the land use modications in the catchment area [8][9][10]. Among other anthropogenic activities that cause marine pollution, dredging and dredged sediment disposal are possibly the most signi cant in terms of pollution dissemination.…”

Environmental impact of the Midia Port - Black Sea (Romania), on the coastal sediment quality

Abstract:The aim of the study was to evaluate the impact of potential pollution sources, mainly from the upstream anthropogenic sources and port-related activities. The investigated area covered a wide range of anthropogenic impacts (e.g., industrial wastes, storm water runo , accidental oil spills, intentional discharges and shipping activities). The quality of water and sediments was assessed using standard methods, as physical-chemical parameters, chemistry and biology (microbiology, ecotoxicology) aiming to gure the level of pollution and the e ect of portrelated activities. Seawater quality results agreed generally with environmental standards. Though, in some samples the concentrations of sulphates (mg/l) and heavy metals (µg/l), as B, As and Se exceeded the recommended limits, without posing a serious environmental concern. Most of the surface sediment samples contain critical levels of hydrocarbons (C>12), (mg/kg), polycyclic aromatic hydrocarbons (ng/g) and polychlorobiphenyls (ng/g). For some heavy metals (mg/kg), exchangeable concentrations were found to be very close or above the regulations. The signicance of this study is incontestable taking into account the lack of previous relevant historical data of this area. In this sense, it was possible to indicate, in general, good environmental conditions, despite the industrial and concentrated local port-related activities in the investigated area.

“…There are plenty ways from the conventional methods to the isotope traces (Appleby et al, 1986;Oldfield, 1978, 1983) for the determination of sedimentation rates. Dating of sediment cores using 210 Pb and 137 C radioisotopes is the more acceptable way in the lakes if the accretion rates are relatively constant throughout the given period of time (Gharibreza et al, 2013).…”
