Environmental radioactivity in a sediment core from Algiers Bay: Radioecological assessment, radiometric dating and pollution records

Sediment pollution: An assessment of anthropogenic and geogenic trace element contributions along the central Algerian coast

“…This is followed by clay, with an average mass percentage of 20.8 %, while fine sand, is the smallest fraction in sediment with a mean percentage of 2.63 %. These findings indicate that the high supply of fine sediments in the study area was probably due to the lack of substantial river inputs (Ergin and Yörük, 1990) and the increased episodic floods and associated mudflows during the last decades (Taieb Errahmani et al, 2020). The results of texture analysis additionally show that the average grain size followed the order of core A > core B > core Z, ranging from 10.5 µm for core A to 6.75 µm for core Z with a mean value of 9.24 µm (Suppl.…”

“…On the other hand, the inner part of Algiers Bay contains paper and iron factories, chemical and textile industries, desalination plants, metal processing, food and beverage manufacturing, tanneries and oil (Bachouche et al, 2017). Additionally, the port of Algiers which is located in the western part of the bay hosts some of such industries, as well as oil refinery plant and petrochemical factory, which impact the adjacent marine environment (Taieb-Errahmani et al, 2020). The Intensive maritime traffic and urban wastes in the capital are the other factors that influence sediment quality.…”

Eco-Toxic Risk Assessment of Nearshore Sediments in Bay of Bengal - Environmental Radioactivity and Ecological Risk as a Proxy

“…The percentage transfer of a dosage consumed in the soil to an appropriate dose and the level of outdoor occupation will be assessed. Efficient dose equivalent (mSv y -1 ) was determined by (UNSCEAR, 2000;Taieb et al 2020):…”

“…The usage of surface sediment indices in marine environments is the primary tool used to determine the environmental condition (Zhou et al 2020). Accumulation and dissemination of natural radioactive elements often useful for the detection of natural radioactivity of environmental contamination (UNSCEAR, 2000;Taieb Errahmani et al 2020). The progeny radioactivity of the typical decay sequence cannot be in considerable equilibrium with their parents in the marine ecosystem (IAEA, 2003).…”

Depth-distributions and migration of fallout radionuclides in mountain soils from Chréa National Park (Algeria): The role of rhizospheres

“…Energy and resolution calibrations were determined using point sources of 241 Am, 137 Cs and 60 Co. The detector efficiency was calibrated as described in Taieb Errahmani et al (2020). In-house calibration sources were prepared by spiking soil samples with liquid sources of 152 Eu and 133 Ba.…”
