1 Απρ 2002 · Selenium poisoning in fish can be ‘invisible’, because, the primary point of impact is the egg, which receives selenium from the female's diet (whether consumed in organic or inorganic forms), and stores it until hatching, whereupon it is metabolized by the developing fish.

selenium and its compounds (ECCC and Health Canada, 2017). In response to numerous health risks, public health agencies have developed screening values for selenium in ambient water and fish potentially impacted by elevated selenium of geologic or anthropogenic origin. Consumption of selenium-contaminated fish is anticipated to supply a
29 Ιουν 2004 · This study showed that effects in fish were linked to selenium exposure via sediment, benthic organisms, detritus or a combination of sediment compartments.
22 Νοε 2018 · Selenium poisoning may result from water systems whenever new agricultural runoff flow through a normally dry, undeveloped lands. This process leaches natural soluble selenium compounds (such as selenates) into the water, which may then be concentrated in emerging wetlands.
The report examines the health risks of consuming elevated levels of selenium from dietary sources such as fish, aquatic plants and drinking water. Chronic selenium exposure, called selenosis, can cause fatigue, damage to nails and hair, and can have some neurotoxic effects.
6 Μαΐ 2010 · Oviparous (egg-laying) vertebrates such as fish and waterbirds are the most sensitive organisms to Se of those studied to date. Toxicity can result from maternal transfer of organic Se to eggs...
1 Απρ 2002 · Hazard is characterized in terms of the potential for food-chain bioaccumulation and reproductive impairment in fish and aquatic birds, which are the most sensitive biological responses for estimating ecosystem-level impacts of selenium contamination.
