“…Dried samples were sieved with a 400 mesh (63 µm) sieve. Approximately 118 g of each sample was placed in polyethylene containers with cylindrical screw cap (5.5 cm diameter and 5 cm height) for gamma measurement and sealed tightly [15]. Before starting the gamma activity analysis, the vessels were kept closed for four weeks to achieve a balance between 226 Ra and the short-lived generation [16].…”

In this research, the concentrations of natural (226Ra, 232Th and 40K) and anthropogenic (137Cs) radionuclides were measured in sediment samples collected from the Borçka Dam Lake using a high purity germanium detector (HPGe). The activity values ranged from 4.79-21.46, 9.36-20.65, 238.01-721.26 and 0.79-6.81 Bq kg-1 for 226Ra, 232Th, 40K and 137Cs respectively. The average 226Ra, 232Th and 40K activity concentrations calculated for the sediment samples were found to be lower compared to world average values reported by UNSCEAR. In addition, radiological hazard indices were determined and compared with the international permissible values. The results of this study revealed that there is no significant health risk for people exposed to sediment samples in this region.

“…Also the next object of our study, the bivalve, M. galloprovincialis (Lamarck, 1819) remains to be an important indicator for the environmental control [92][93][94] of diverse trace elements [95,96] and radionuclides [97]. However, in contrast to L. elliptica, this mollusc species is widely exploited as seafood and in some areas is also a broadly cultivated organism in aquaculture [98][99][100][101].…”

Conchixes: organic scaffolds which resemble the size and shapes of mollusks shells, their isolation and potential multifunctional applications

et al. 2020

Molluscan shells are an example of a mineral-based biocomposite material, and most studies to date have focused on understanding their biomineralization mechanisms. Meanwhile, large amounts of these shells are produced as waste globally by seafood which is used by other industries as a source of biogenic calcium carbonates. In this study, we propose a simple methodological approach for isolation of Conchixes, the organic scaffolds that resemble the size and shapes of mollusks shells, using gentle EDTA-based demineralization of the shells. Such mineral-free biological materials have been extracted from selected representatives of marine and fresh water bivalves, as well as from marine and terrestrial gastropods under study. Key pathways to practical applications of molluscan conchixes with regards to pharmacy, cosmetics, feed and feed additives, biomedicine and bioinspired materials science are also discussed.

“…In addition to aforementioned studies, numerous recent studies have been conducted on the determination of the radioactivity concentration of tea (Baltas et al, 2016;Gökmen et al, 1995;Varinoğlu et al, 1995). In the study has been shown that radioactivity has been detected in the Black Sea region even after years by Varinlioglu et al, Furthermore, this study has been explained that the 137 Cs activity has not yet been determined (Varinoğlu et al, 1995).…”

Tea is the second most consumed plant worldwide after water and it can be grown in humid climates. Considering the frequency of consumption, it is inevitable for the tea plant to become a very important field of study both in terms of commercial and public health. The tea plant appears in four different forms which are green tea, black tea, oolong tea and white tea depending on the production method. Especially white tea has started to attract the attention of science in recent years due to its antioxidant effect. The aim of this study is to examine radionuclides and elemental concentrations of black and white tea collected from Karadeniz in Turkey. Natural and artificial radionuclides concentrations were determined using gamma-ray spectrometry. 226Ra, 232Th, 40K, 137Cs were detected in both black and white tea samples. Elemental concentrations of the black and white tea were determined using energy dispersive x-ray fluorescence (EDXRF) spectrometry. Scanning electron microscopy (SEM) micrographs were obtained for black and white tea samples. 226Ra and 137Cs activity concentrations of black tea are higher than white tea however 232Th and 40K activity concentrations of white are higher than black tea. Total dose value of white is higher than black tea.
