Modification of mercury toxicity by selenium: practical importance?
The interaction between mercury and selenium may involve a variety of toxicologically and biochemically distinct processes. In this paper, the interaction between inorganic mercury and sodium selenite, the interaction most extensively studied, as well as the interaction between methylmercury (MeHg) and selenium, the interaction perhaps most significant for non-occupational human populations, wi...
متن کاملMercury toxicity
Mercury is a metal found in elemental, organic, and inorganic forms in the nature. This substance is present in the composition of earth crust, soil, air, and even in some tissues of plants and sea animals. Each year nearly 3400 tons of mercury compounds are released in the environment, which 95% settle in the soil, 3% in the oceans, and 2% in the atmosphere. Different industrial products li...
متن کاملModification of methylmercury toxicity and metabolism by selenium and vitamin E: possible mechanisms.
Selenium and vitamin E exert powerful effects in reducing acute or chronic methylmercury toxicity. Levels of selenium normally found in foods (below 1 ppm) delay the onset of toxic signs caused by much higher levels of methylmercury. Tissue levels of mercury in selenium-supplemented animals equal or exceed those found in animals given methylmercury alone. Selenium does not appear to act by simp...

Phenylmercuric chloride in a dose 30 ppm of mercury alone and the same dose supplemented with 4 ppm of selenium were fed to chickens of both sexes for 8 weeks. Body weight, mortality rate, pathological changes and the level of mercury in the muscle, liver, and kidneys of the laying hens and cocks were analysed. After the dosage period, the mean body weight of the hens was unaffected, while in t...
