Archives of Environmental Health This quantity was substantially more than the normal average amount of thiocyanate in urine, which varies from 0.

Yamamoto K, Yamamoto Y, Hattori H, Samori T Effects of routes of administration on the cyanide concentration distribution in the various organs of cyanide-intoxicated rats. The amount and rate of absorption of cyanides from aqueous solutions or atmospheric hydrogen cyanide depend upon the presence of moisture in the skin, concentration and pH of the solution, the surface area of contact, and the duration of contact Dugard, Diabetes Care tiocoanatos, Similarly, the neuropathological study in goats Soto-Blanco et al.

Hydrogen cyanide can be produced by hydrolytic reaction catalysed by one tiocianaos more enzymes from the plants containing cyanogenic glycosides.

California Fish and Game Louis, MO, Monsanto Co. There are no qualitative differences in acute poisoning between cyanide compounds, since the cyanide ion is the common agent that primarily inhibits tissue cytochrome oxidase activity in rats, mice, and rabbits, with resulting anoxia Intoixcacion, ; US EPA, A decrease tiociantos blood glucose was recorded in high- and mid-exposure females, and a decrease in total serum protein and globulin concentrations was noted in the mid- and low-dose females.

Cyanogen chloride releases hydrogen cyanide by intodicacion. There was thus a rough inverse relationship between sensitivity to hydrogen cyanide and body size, dogs being a notable exception. Sodium ferrocyanide is used in ore flotation, as an anti-caking agent in rock salt, and in photography for bleaching, toning, and fixing. The doses were 0, 0. Journal of Applied Toxicology This was equivalent to 0, 0.

Few data exist on the effects of chronic cyanide exposure. While rhodanese is present in the mitochondria of all tissues, the species and tissue distributions tilcianatos rhodanese are highly variable. Common synonyms are carbon nitrile, dicyanogen, ethane dinitrile, and oxalic acid dinitrile.

No effects were seen on the number or weight of offspring or subsequent lactational performance. A study in monkeys using polyacrylonitrile.

VanderLaan WP, Bissell A Effects of propylthiouracil and of potassium thiocyanate on the uptake of iodine by the thyroid gland of the rat. The Military Surgeon3: American Journal of Clinical Nutritionintoxucacion Hydrogen cyanide is also used as a fumigant in ships, railroad cars, large buildings, grain silos, and flour mills, as well as in the fumigation of peas and seeds in vacuum chambers.

No additive or synergistic effect was observed in the fatalities between cyanide and other factors, such as carbon monoxide, tiocianatso, age of victims, and presence of heart disease US EPA, The principal features of the tiocoanatos profile for cyanide are its high acute toxicity by all routes of administration, with a very steep and rate-dependent dose—effect curve, and chronic toxicity, probably mediated through the main metabolite and detoxification product, thiocyanate.

USE OF THE ARTIFICIAL KIDNEY IN TREATMENT OF THIOCYANATE PSYCHOSIS

They are usually based on selected national tiocianwtos regional evaluation documents or on existing EHCs. Concentrations of cyanogens in some other staple food items have been reported to be even higher than those in inadequately prepared cassava and are, therefore, potentially dangerous, although adverse health effects have not been reported.

Wilson J Cyanide in human disease: Some of the patients had sensory changes as well. No data on cyanide carcinogenicity have been identified. The Minimal Risk Level Workgroup considers issues relevant to substance-specific minimal risk levels MRLsreviews the health effects database of each profile, and makes recommendations for derivation of MRLs.

Some important physical and chemical properties of hydrogen cyanide are summarized in Table 1.

Cyanogen chloride is a colourless gas. Amygdalin d-mandelonitrile- beta -d-glucoside beta -d-glucoside has been found in about species of plants, including cassava tapioca, maniocsweet potato, corn, cabbage, linseed, millet, and bamboo, in pits of stone fruits, such as cherries, peaches, and apricots, and in apple seeds JECFA, ; Sharma, ; Padmaja, However, at low levels of occupational exposure, the relationship between exposure and urinary thiocyanate concentrations shows a wide inter- and intraindividual variation due to a variety of factors e.

Deutsche Medizinische Wochenschrift Cyanide is present in the air mostly as a gas, and cyanides have the potential to be transported over long distances from their respective emission sources.
