Symptoms of cyanide toxicity can occur within seconds of inhalation of hydrogen cyanide or within minutes of ingestion of cyanide salts. Detection limits for the different intoxicaciob for hydrogen cyanide range from 0.

Sodium cyanide is extensively employed in a large number of industrial processes, including electroplating and case-hardening of metals; the extraction cyanidation of gold and silver from ores; base metal flotation; coal gasification; and the fumigation of ships, railroad cars, buildings, grain silos, flour mills, seeds in vacuum chambers, and inotxicacion.

The reaction occurs rapidly in an alkaline environment, and the hydrolysis is complete in 10 min.

The absence of a dose—response relationship would suggest that cyanide work was not causal. In addition, thiocyanates often succeed in controlling hypertensive headaches that are resistant to other forms of treatment.

Due to its high dependency on oxidative metabolism and limited anaerobic capacity, the central nervous system is particularly vulnerable to cyanide intoxication Way, Cyanide occurs naturally as cyanogenic glycosides in at least plants Figure 1. More than 30 large-scale accidental releases of cyanide to water systems have been reported since ; these include transportation accidents, pipe failures, and tailings dam-related releases Korte et al.

The principal routes of occupational exposure to cyanides are via inhalation and, to a lesser degree, skin absorption.

It is released into the atmosphere from biomass burning, volcanoes, and natural biogenic processes from higher plants, bacteria, algae, and fungi Fiksel et al. Ohya T, Kanno S Formation of cyanogen chloride during the chlorination of water containing aromatic compounds and ammonium ion.

The quantity of cyanide was reported to depend on the ripeness of the cherries and the year in which they were harvested. Calcium cyanide is used chiefly as a fumigant, because it readily releases hydrogen cyanide when exposed to air; as a fertilizer, defoliant, herbicide, and rodenticide; as a stabilizer for cement; and in stainless steel manufacture ACGIH, Outbreaks of konzo have been reported in intoxicafion Democratic Republic of the Congo formerly Zaire since Liebowitz D, Schwartz H Cyanide poisoning: New England Journal of Medicine Cooles P Diabetes and cassava in Dominica.
