“…The main source of nitrogenous pollutants in LB is the agricultural drainage water and fish farms neighbouring to the lake (El‐Reefy et al . ; Nassar & Gharib ). Further research work needed to be done to reduce the hazardous impact of pollution or pollution itself from this very important lake.…”

Understanding the impacts of seasonal variations on fate and distribution of natural and introduced microbes are important for proper public health, risk assessment and water management of Lake Burullus, Egypt (LB) as water receiving body. The effects of mixing processes on microbial loads in Lake and discharged aquacultural wastewater (AQ) and agricultural drainages (AG) were assessed. Microbiological examinations of discharged waters in this study revealed that total bacterial count (TBC), and total coliform count (TCC) were significantly high at P 0.05 in aquacultural wastewater than both LB and AG. Total fecal coliform count (TFC) and total fecal streptococcus (TFS) were determined and showed that AG has significantly high at P 0.05 comparing to both LB and AQ. No seasonal differences in-between all indictors values of LB, while AG wastewater values were mostly higher than both AQ and LB water samples with declining attitude between sampling points. In case of TBC, TCC and TFC, the microbial loads of lake water were highly affected by receiving water but in case of TSF, the water shows no affects. Contrary, for discharged waters, both show reduction in count that is meaning of dilution processes. As excessive discharge of raw wastewater may present a risk related to high increased rate of TBC and TCC in lake water annually by 27.8 and 33.0% at 500 m points, respectively.

“…It has been established that the presence of organics may strongly influence the migration behavior of radionuclides through adsorption and complexation (El-Reefy et al, 2014;Ramasamy et al, 2014). For example, interactions between radionuclides and humic/fulvic acids generally lead to stable complexes (Carlsen, 1985).…”

“…The fate and transport of radionuclides in the environment have been extensively studied since human exposure to radiation can have detrimental health effects. (Abd El-mageed et al, 2011;El-Reefy et al, 2014;Sam et al, 1998;Shetty et al, 2006;Wang et al, 2015). However, radionuclides can also serve as effective geochemical indicators.…”

“…The study of radionuclides in sediments is usually built on its relationships with sedimentological variables, given their known association in coastal and ocean sediments (Ligero et al, 2001;El-Reefy et al, 2014;Valan et al, 2017;Lin et al, 2020). Factors that explain this affinity are the availability of more adsorption sites in fine-grained sediments than in coarse-grained sediments, binding and fixation in organic matter, incorporation in suspended materials, and dilution effects caused by the presence of carbonates, among others (Ligero et al, 2001).…”

Spatial trends in the distribution of natural radioisotopes in the bottom sediments of Santos Basin (Brazil)

Ocean and Coastal ResearchActivities related to the marine exploration of oil and gas reservoirs tend to cause a concentration of natural radionuclides in related materials. As such, knowledge regarding the distribution of radionuclides in sedimentary basins with current oil operations is essential for modeling radiological hazards and possible risks of site contamination. This study investigated the distribution of 226Ra and 228Ra, radioisotopes from the 232U and 232Th decay chains in bottom sediment of the Santos basin. Sediment samples were collected from sites in a sampling grid based on depth contours and were analyzed through high-resolution gamma spectrometry. A distribution model of the spatial variation of these isotopes, the first of its kind for the Basin, supported the interpretation of similar tendencies in their distribution. From studying the spatial trends of the mean levels of the isotopes with descriptive statistics and variance analysis, latitudinal and bathymetric differences in the content of radionuclides emerged. These differences are probably derived from the distinct sources of these elements, as 226 Ra originates in the deep ocean from the decay of parent 230 Th and from the patterns of sedimentation driven by open ocean circulation, while 228Ra is supplied by terrigenous materials transported by the northward-flowing Brazilian Coastal Current.
