Selenium: A global contaminant of significant concern to environment and human health

Assessment of Selenium Contamination in Sediments of the Aby and Tendo Lagoons in Côte d’Ivoire

“…Selenium can be released into the environment through natural and anthropogenic processes. Natural sources of Selenium include soil erosion, rock weathering, and volcanic emissions [4] [5]. Anthropogenic sources of Selenium include mining, fossil fuel combustion, agriculture, and pesticide use [6] [7].…”

Invasive Round Goby (Neogobius melanostomus) Fish from the Southern Baltic as a Source of Arsenic and Selenium—Food Safety Aspects

“…On one hand, they exhibit specific toxicity and potential carcinogenicity (especially As), and on the other hand, they have positive impact, especially Se [ 3 , 4 , 5 ]. Research on their effects on the human body yields conflicting results [ 6 , 7 , 8 ].…”

“…However, the range between necessary dietary doses and toxic doses is relatively narrow [ 1 ]. Low doses of Se and selenoproteins can induce dermatological, endocrinological, and neurological changes [ 8 ]. Conversely, excessive exposure to Se can facilitate the development of chronic degenerative diseases [ 6 ].…”

“…Arsenic and selenium are naturally occurring elements that are commonly found in the environment, particularly in rocks and soil [ 8 ]. Currently, significant sources of contamination in terrestrial and aquatic ecosystems include industrial activities such as mining, the use of artificial fertilizers, the electrical industry, and mineral combustion [ 8 , 10 , 15 ]. Both elements occur in inorganic forms as well as in organic compounds.…”

“…Monitoring the levels of As and Se in fish is also crucial due to the accumulated and prolonged intake of these elements, which can lead to adverse health effects. This kind of research is also important because legal regulations and recommendations regarding the control of exposure to As and Se are still under discussion and being updated [ 4 , 5 , 8 , 20 ].…”
