Zotero Mendeley EndNote. However, use of toxic agents in wars and in attack started in the first ages of written history. The threat of chemical weapons reached to important extents in the last part of the 20th century and became a current issue in the mass destructions and terrorist events. Therefore, nowadays and generally in the 21st century, it should be accepted that the chemical weapons take their part along with the conventional weapons and they have become most possible warfare and attack methods. Knowledge is provided by education.

Advances in toxicology and medical treatment of chemical warfare nerve agents

Mustard agents are highly toxic and abundant warfare chemicals, primarily affecting ocular tissues, with no specific treatment antidote. The purpose of the present study was to examine the efficacy of novel metallocomplexes, known to inhibit the formation of highly reactive free radicals, to reduce ocular injury induced by nitrogen mustard NM. Examiners masked to the treatment groups assessed the extent of ocular injury and the response to treatment using clinical, histologic, and biochemical criteria. Exposure to NM followed by administration of carrier alone saline caused severe and long-lasting injury to ocular anterior segment structures. These were also associated with better preservation of systemic antioxidant status. Zinc or DFO alone afforded lower levels of protection. No toxic effects of these complexes were observed.

VX (nerve agent)

A Review of Chemical Warfare Agents and Treatment Options

Chemical warfare agents CWAs are unarguably one of the most feared toxic substances produced by mankind. Their inception in conventional warfare can be traced as far back as the Middle Ages but their full breakthrough as central players in bellic conflicts was not realized until World War I. Since then, more modern CWAs along with efficient methods for their manufacture have emerged and violently shaped the way modern warfare and diplomatic relations are conducted. Owing to their mass destruction ability, counter methods to mitigate their impact appeared almost immediately on par with their development. These efforts have focused on their efficient destruction, development of medical countermeasures and their detection by modern analytical chemistry methods.

VX is an extremely toxic synthetic chemical compound in the organophosphorus class, specifically, a thiophosphonate. In the class of nerve agents , it was developed for military use in chemical warfare after translation of earlier discoveries of organophosphate toxicity in pesticide research. In recent years, VX was found to be the agent used in the assassination of Kim Jong-nam. In its pure form, VX is an oily, relatively non-volatile , liquid that is amber-like in color.

Note to reader: This fact sheet is intended to provide general awareness and education on specific chemical agents. For information on preparedness and response e. Nerve agents are chemicals that affect the nervous system. The health effects are similar to those produced by some pesticides. These agents are man-made and have been manufactured for use in chemical warfare. These agents are known to be present in military stockpiles of several nations, including the United States. Nerve agents do not occur naturally.

They are divided into two classes of G and V agents. Most of them are liquid at room temperature. NAs chemical structures and mechanisms of actions are similar to OP pesticides, but their toxicities are higher than these compounds. The main mechanism of action is irreversible inhibition of Acetyl Choline Esterase AChE resulting in accumulation of toxic levels of acetylcholine ACh at the synaptic junctions and thus induces muscarinic and nicotinic receptors stimulation. However, other mechanisms have recently been described. Central nervous system CNS depression particularly on respiratory and vasomotor centers may induce respiratory failure and cardiac arrest. Intermediate syndrome after NAs exposure is less common than OP pesticides poisoning.

CWAs include five primary categories: nerve agents, asphyxiants, blistering agents, toxic industrial chemicals and blood agents.

Among the Weapons of Mass Destruction, chemical warfare CW is probably one of the most brutal created by mankind in comparison with biological and nuclear warfare. Chemical weapons are inexpensive and are relatively easy to produce, even by small terrorist groups, to create mass casualties with small quantities. The characteristics of various CW agents, general information relevant to current physical as well as medical protection methods, detection equipment available and decontamination techniques are discussed in this review article.

Мужчина смотрел на него недовольно. - Was wollen Sie. Что вам. Беккер понял, что ему следовало заранее отрепетировать разговор, прежде чем колотить в дверь.

 Тогда за дело, - сказал Стратмор, положил ей на плечо руку и повел в темноте в направлении Третьего узла. Над их головами куполом раскинулось усыпанное звездами небо. Такие же звезды, наверное, видит сейчас Дэвид в небе над Севильей, подумала. Подойдя к тяжелой стеклянной двери, Стратмор еле слышно чертыхнулся. Кнопочная панель Третьего узла погасла, двери были закрыты.

ТЕМА СООБЩЕНИЯ: П. КЛУШАР - ЛИКВИДИРОВАН Он улыбнулся. Часть задания заключалась в немедленном уведомлении. Но сообщать имена жертв… с точки зрения человека в очках в металлической оправе, это было признаком особой элегантности стиля. Его пальцы снова задвигались, приводя в действие сотовый модем, и перед глазами появилось: СООБЩЕНИЕ ОТПРАВЛЕНО ГЛАВА 26 Сидя на скамейке напротив городской больницы, Беккер думал о том, что делать .

Facts About Nerve Agents

Я не видела смысла впутывать моего спутника, да и самой впутываться в дела, связанные с полицией. Беккер рассеянно кивнул, стараясь осмыслить этот жестокий поворот судьбы.

Затем он одним движением швырнул ее на пол возле своего терминала. Сьюзан упала на спину, юбка ее задралась. Верхняя пуговица блузки расстегнулась, и в синеватом свете экрана было видно, как тяжело вздымается ее грудь.

 - Говорит Лиланд Фонтейн. Слушайте меня внимательно… ГЛАВА 112 - Надеюсь, вы знаете, что делаете, директор, - холодно сказал Джабба.  - Мы упускаем последнюю возможность вырубить питание. Фонтейн промолчал.

 - Ему ведь всего тридцать лет. - Тридцать два, - уточнил Стратмор.
