Gaz lacrymogène et santé

Lien vers l’article

Je regarde un transfert d’une journée d’événements à Paris, via RT. Grâce à la technologie moderne, tout ce qui se passe se fait simplement sentir dans ma chambre. Bien pas tous. Je ne peux pas sentir le gaz lacrymogène, mais comme je tombe dans ceux qui n’ont pas peur de dire ce qu’ils pensent, il suffit de suffisamment de cassettes pour se souvenir du jour où je l’ai inhalé dans la rue. Puis, lorsque les yeux sont enflés et flous, peu de gens ont déjà pensé à ce qu’est une larme. Ensuite, il est seulement important d’arrêter la douleur et de voir. Normal

Maquereau ou lacrymatoire Le gaz qui pleure appartient aux armes chimiques. On peut affirmer que cela ne sert qu’à disperser les manifestants et à ajouter leur version de leurs traits – maudits, sales, voyous, gens, héros. Déjà par affinités personnelles. Il existe plusieurs types de gaz lacrymogène, à savoir: – Spray au poivre – Spray de Pava – gaz CS – gaz CN – gaz CR Le spray au poivre est principalement destiné à un usage personnel comme défense contre les attaques et est composé de piments forts et de poivrons, qui sont ajoutés au maïs. Tout est naturel, n’est-ce pas? PAVA spray est utilisé par la police britannique. Il s’agit d’une solution à 0,3% de vanillylamide d’acide pélargonique (PAVA), de capsaïcinoïde synthétique, d’éthanol et d’azote sous forme de gaz. Il est généralement utilisé à faible distance et agit sur les yeux, provoquant une douleur intense et obligeant à fermer les yeux.

Le gaz CS est le 2-chlorobenzalmalononitrile (également appelé o-chlorobenzylidène malononitrile; formule chimique: C10H5ClN2) et le cyanocarbone, qui sont tous stockés dans des cartouches. Cause une sensation sévère dans les yeux avec fermeture, larmes, nausée, désorientation, fermeture nasale, démangeaisons, toux et difficulté à respirer. La police exprime son amour pour les manifestations. Le gaz CN est du chlorure de phénacyle, également connu sous le nom de chloroacétophénone, peut être synthétisé par acylation de Friedel-Crafts du benzène en utilisant du chlorure de chloroacétyle, le chlorure d’aluminium servant de catalyseur. Il a été considéré qu’en raison de sa toxicité prononcée, il ne serait pas utilisé, mais, comme toujours, le mal causé par l’homme prédomine et fait partie du spray MACE connu. Il est le favori des formations paramilitaires. Le gaz CR ou dibenzoxazépine a été mis au point par le ministère britannique de la défense. Il est dix fois plus efficace que le reste et est cancérigène. Il est également mentionné par la Human Rights Association. Il irrite la peau, crée des attaques de panique, des suffocations, un combat aérien. Utilisé à l’intérieur, il peut provoquer la mort par étouffement et un œdème des poumons.

Effets sur la santé
L’utilisation de gaz lacrymogène a été considérablement envahie par la végétation ces dernières années. Il est utilisé dans les villes densément peuplées, telles que Le Caire, Istanbul, Rio de Janeiro, Manama (Bahreïn) et Hong Kong. Également dans les émeutes à Ferguson, dans le Missouri. L’utilisation de gaz lacrymogène entraîne de nombreux problèmes de santé qui peuvent être aigus et chroniques. Aigu Ce sont des effets immédiats après l’utilisation et le but de l’utilisation est d’induire ces effets. Irritation des yeux, de la bouche, du nez, de la peau et du système respiratoire. Les effets cutanés comprennent la douleur, des démangeaisons, des rougeurs et une possible dermatite de contact allergique. Déchirure oculaire (oculaire), démangeaisons, blafarospasme, douleur, rougeur et sensation de brûlure. 
Respiratoire

Les effets sur le système respiratoire et leur histoire sont un exemple passionnant de mauvaise science. Afin de prouver que les larmes étaient inoffensives, des études ont été menées sur des animaux de laboratoire et une étude sur des soldats volontaires en bonne santé n’a été réalisée que sur sept sujets; tous ceux ayant déjà eu des problèmes respiratoires étaient exclus de l’étude. Ce n’est pas comme ça. Toutes les études comparent les résultats avec des personnes qui ont déjà été exposées à une activité de l’acide lactique plutôt que de manière chronique. C’est comme beaucoup d’autres agents si seulement de petites doses sont comptées. Cependant, qu’en est-il des expositions chroniques et en Turquie, par exemple? Personne ne conteste les effets actuels, ils ne peuvent pas le voir. D’autre part, si nous introduisons dans l’équation d’un groupe à risque tel que les fumeurs, ceux qui sont plus exposés au radon, les fumeurs plus exposés au radon, les personnes asthmatiques, souffrant de douleur obstructive pulmonaire chronique et d’autres maladies pulmonaires chroniques, obtiennent toutefois des résultats différents. Quelqu’un dira – et que feront-ils lors des manifestations? – et ce ne sera pas juste. Le droit humain fondamental est de se rebeller contre ce qui est considéré comme une injustice.

Des manifestations massives en Turquie ont montré que des problèmes respiratoires importants tels que l’apnée, l’œdème pulmonaire, des arrêts respiratoires et une hémoptysie se produisaient. Trouver chez les femmes était pire que chez les hommes. En ce qui concerne les zones densément peuplées, les locataires environnants étaient chez eux. Une étude plus sérieuse a montré que des problèmes respiratoires chroniques se sont produits chez 55 personnes sur 93 ayant été exposées au gaz lacrymogène plus d’une fois. L’effet primaire prolongé est la bronchite chronique. Problèmes respiratoires chez le personnel militaire Les militaires sont exposés à de nombreuses déchirures lors de leur entraînement régulier. La vérité est qu’ils ont un masque à gaz, mais cela ne signifie pas que chacun d’eux fonctionne parfaitement. Les effets chroniques sont la toux, les maux de gorge, la sinusite, la rhinopharyngite, la bronchite et autres. Les problèmes augmentent surtout après la grippe. Comme ce problème dure longtemps, la quantité de gaz utilisée est réduite. Maintenant, ce n’est pas clair pour moi, s’ils connaissent le problème, pourquoi nient-ils que des civils puissent être blessés?
Effets sur les yeux

Il est logique que les yeux d’une étoile à gaz lacrymogène. C’est leur but. Cependant, si l’objectif d’invalidité temporaire ne devrait pas être l’objectif de blessures permanentes. La haine pour d’autres idées est-elle si forte? Lésion oculaire, œdème stromal, dépression conjonctivale, injection de vascularisation oculaire profonde. Autres complications oculaires telles qu’hémorragie, neuropathie traumatique de l’œil, kératite, kératoplastie trophique, symblephonie, pseudoptérigisme, glaucome et cataracte. Impressionnant. 
Blessures à la peau Une grande quantité de gaz lacrymogène a été utilisée chez les réfugiés vietnamiens à Hong Kong. Il y a eu de nombreuses blessures à la peau sous forme de brûlures, en particulier au niveau du visage, du cou et des épaules. En outre, une dermatite et des lésions vasculaires se produisent. 
Troubles gastro-intestinaux et cardiovasculaires

L’irritation du système gastro-intestinal va avec les nausées, les vomissements, la diarrhée et les hématomes. Comme pour le système cardiovasculaire, les effets sont la tachycardie et l’hypertension transitoire. En outre, les attaques de panique et les peurs.
Blessures graves et mort
On signale de nombreux effets graves, blessures graves et décès. Cela s’applique particulièrement à une utilisation en intérieur. Plusieurs décès ont été signalés dans plusieurs prisons. C’est une pratique courante dans les prisons qui sont souvent mal ventilées. Ceux qui ont déjà une maladie pulmonaire précoce sont les plus susceptibles de souffrir. Les morts étaient en Égypte, en Turquie, à Bahreïn et au Brésil. Le cas le plus célèbre est celui de 37 morts à la fois dans une prison en Egypte. Des cas d’avortement ont été rapportés après une exposition au gaz lacrymogène. Je suis optimiste quand je crois que ces mots écrits toucheront au moins une personne qui ordonne l’utilisation de l’essence. Un seul à s’arrêter et dire, qu’il y ait d’autres moyens. Force force le pouvoir. Il y a toujours un moyen de conclure un marché. Il suffit que l’accord soit recherché. La vie a montré qu’il n’ya pas de problème qui ne puisse être résolu par un accord. Je sais que je donne de faux espoirs, mais au moins j’essaye, essaie et toi, quelqu’un va parfois s’arrêter.

ISRAEL’S USE OF TEAR GAS SCRUTINIZED

Lien vers l’article

By Glenn FrankelMay 31, 1988

JABALIYA, GAZA STRIP — It was a typical week in this densely populated refugee camp. There were Israeli soldiers and Arab stone throwers playing cat-and-mouse games through the winding, garbage-strewn alleyways. There were rubber bullets and fiberglass billy clubs on one side and slingshots, bottles and concrete blocks on the other. And, as always, there was tear gas.

For two days, Ikkram Said, a slender, 27-year-old woman who was four months pregnant, said she could smell fumes wafting into her courtyard from outside. Even with the windows closed, she said, her eyes stung, she coughed constantly and had trouble breathing. Then one day she noticed blood when she went to the toilet and became frightened.

She had a friend drive her to the camp’s United Nations health clinic and was advised to go to Shifa Hospital in nearby Gaza City. By the time she got there she had stomach cramps and uterine contractions. Soon after, she miscarried.

Said’s story represents another question mark in one of the most troubling, elusive and emotive issues to arise during the 23-week Arab uprising: the effects on the Palestinian population of the Israeli Army’s frequent use of tear gas as a nonlethal riot-control weapon.

Palestinian doctors and officials working for the U.N. Relief and Works Agency (UNRWA) that operates the refugee camps contend there have been more than 1,200 injuries, dozens of miscarriages and at least 11 deaths from tear gas since the uprising began Dec. 9. The Washington-based Arab Anti-Discrimination Committee has put deaths at 41 and used that figure in a successful lobbying campaign that last month led the American manufacturer of the gas to suspend sales to Israel.

While they concede they lack hard data and autopsy results to verify many of their claims, these sources contend the weight of circumstantial evidence clearly indicates that tear gas is at least a significant contributing factor in deaths and miscarriages among a refugee camp population that, even in the best of times, is in a precarious state of health.

« There is until now no solid scientific proof, but certainly the accumulated evidence is strongly incriminating, » said Dr. Samir Badri, a Palestinian who is UNRWA’s chief health officer in the Gaza Strip.

« When you see a woman with no previous history of miscarriages or bleeding, and after exposure to tear gas she bleeds and aborts, you can say safely it is the gas. »

Israeli officials contend the Palestinian claims are based on false or unsubstantiated information and are designed to fuel a propaganda crusade that portrays Israel as waging a form of chemical warfare against a hapless civilian population.

« We have not seen any cases where it could be proven by a coroner that anybody has been killed due to exposure to tear gas, » said Brig. Gen. Yehuda Danon, the Israeli Army’s surgeon general, in a telephone interview, « and we have no scientific evidence that there have been more miscarriages following the use of {tear gas}. »

Medical experts say the issue is further complicated by the fact that accurate statistics and unbiased accounts are largely unobtainable in the chaos of civil unrest and military crackdown that has reigned in the occupied West Bank and Gaza Strip since December.

But within the cross fire of charges and countercharges, interviews with Palestinian, Israeli and American doctors who have first-hand experience with tear gas, a reexamination of several cases, and eyewitness accounts during recent months all point to these facts about the use of tear gas during the uprising:There is no credible evidence to support Palestinian claims that the Israelis are using any gas or toxic chemicals other than the standard chlorobenzylidene malononitrile, known as « CS, » manufactured by Federal Laboratories Inc. of Saltzburg, Pa. When properly used outdoors, the gas has limited effects that generally wear off in 15 to 30 minutes.There is, however, much evidence indicating that on numerous occasions soldiers and police have violated the manufacturer’s printed warnings by firing the gas into enclosed areas such as rooms or small courtyards. Most experts agree that such misuse of the gas can be harmful, especially to small children, the elderly, pregnant women and people suffering from heart or lung problems.There is debate over the possible long-term health effects of tear gas and growing concern among human-rights groups and some medical experts about its widespread use in countries including Israel, South Korea and Panama.Health conditions in the squalid, overcrowded refugee camps of Gaza have deteriorated dramatically in recent months due to disruptions of medical services and child feeding programs caused both by Palestinian violence and Israeli military restrictions. As a result, the population is more vulnerable to many kinds of health hazards, one of which is exposure to tear gas.

Upon close examination, some of the U.N. and Palestinian claims appear groundless. After a visit to Gaza last month, UNRWA health director John Hiddlestone told a press conference in Vienna about an incident in which two young Palestinians were beaten by soldiers and confined in a room where a reddish aerosal spray was used. « The room was then shut and after an hour or so two dead bodies were removed, » said Hiddlestone, who said soldiers apparently had used « some very toxic nerve gas. »

Hiddlestone was talking about the death of Basel Yazuri, age 18, who was killed Jan. 8 in the Rafah refugee camp, according to UNRWA officials. But Jerusalem Post reporter Bradley Burston, who visited Yazuri’s house shortly after the incident, said that besides the red powder on the walls and furniture of the room, which apparently came from an Army smoke grenade, there were also multiple bullet holes indicating someone had sprayed the room with an automatic rifle.

UNRWA’s own report on the incident states Yazuri died from bullet wounds and that there was no second fatality. The Army contends Yazuri was shot dead while attacking a soldier with a knife. Arab witnesses at the scene claimed he was badly beaten before being shot, and the question of whether Yazuri’s death was justifiable homicide remains open. But no one except Hiddlestone says he was gassed.

In camps such as Jabaliya, tear gas has become part of everyday life as well as a key element in the mythology of the Palestinian uprising. Children turn the spent metal canisters into toys or wear them proudly as necklaces. Dozens of canisters are hung defiantly from utility lines throughout the camp. Almost every house, it seems, boasts a collection of one or more of the thin tin projectiles or grenade-style rubber containers.

There are no figures available on how much tear gas Israeli troops have used since December, but the use is widespread. Soldiers have fired gas canisters from rifles, hurled grenades by hand and dumped 30-inch-long cans from helicopters. Despite printed warnings on the canisters that the gas is « for outdoor use only » and « may cause severe injury if not used in accordance with this warning, » soldiers pursuing alleged rioters have fired tear gas into houses, stores, clinics and even, on occasion, into hospitals.

Even now, at a time when the frequency of violent incidents and fatalities appears to be dropping, Christine Dabbagh, UNRWA’s information officer in Gaza, says she gets daily reports of injuries including tear-gassing from Jabaliya and other camps. On May 21, for example, UNRWA’s Jabaliya clinic reported treating 11 people for gas, including Said, who later miscarried at Shifa Hospital. The following day the report listed six tear-gas victims, two of whom later miscarried.

Altogther, doctors at Shifa Hospital, which serves most of the northern half of the Gaza Strip, say they treated 378 miscarriage cases between December 1987 and February 1988, the first three months of the uprising, compared to 335 during the same period a year earlier. UNRWA health director Badri says he tried to compile statistics to do a similar comparison at the Rafah refugee camp, but the numbers showed no significant increase.

The causes of miscarriages remain elusive because even in normal times, the estimated rate of miscarriages runs as high as 20 percent. Ikkram Said, for example, had a miscarriage and then bore three children before her latest pregnancy. It is impossible to know in retrospect exactly why she aborted this time. Besides her physical symptoms, doctors say her sense of fear after being exposed to tear gas could have been a factor.

Similarly, the death of a three-year-old girl in Gaza City last Friday remains uncertain. Local residents attributed it to tear gas. But the Army said the girl had not shown symptoms of tear gas inhalation when treated at a local hospital and said her body was spirited away by family members before an autopsy could be performed.

Dr. Issa Satti, director and chief surgeon at Ramallah Hospital in the West Bank, recalled last Feb. 20, when soldiers fired two CS gas canisters into the maternity recovery ward. There were five women and four babies in the ward at the time who were quickly evacuated, Satti said, after which he tried to enter the room to remove the canisters.

« I thought I would just throw them out the window, but I could hardly get into the room, » Satti recalled. « It was so concentrated. I started to cough, and then I couldn’t breathe. Even 24 hours later you couldn’t enter the room. »

Satti, who is one of the West Bank’s best known and most respected physicians, said he has concluded after months of watching soldiers use tear gas in Ramallah that « when used properly outdoors, I think it’s harmless. But we’ve had people who have had gas fired into their homes. Someone kept inside long enough could certainly die. »

An Army spokeswoman said soldiers were instructed to use tear gas only in open areas and that other uses of the gas were in violation of orders. She noted that the Army had taken pains to choose a form of tear gas that would not prove harmful to its own soldiers because sudden wind changes often expose them to its effects.

Brig. Gen. Danon said the Army had relied upon two reports in 1969 and 1971 by the Himsworth Royal Commission into the medical and toxicological effects of tear-gas use in Northern Ireland. Both reports indicated that CS gas was the safest and least toxic and had the least long-term health effects, said Danon.

The Army surgeon general conceded that health conditions in Gaza are poor but said many factors associated with the uprising were to blame. The United Nations’ supplemental feeding clinics for pregnant women and children have functioned only sporadically due to civil violence and to military curfews. Sewage systems and running water have broken down in many places and have not been repaired. Garbage collection is sporadic at best.

« All of these are far more important in terms of their effect on the health of the population than the occasional use of riot-control agents such as tear gas, » he said.

But Dr. Jonathan E. Fine, an internist who is executive director of Physicians for Human Rights, a Boston-based rights group, contended that the Himsworth reports had drastically underestimated the harmful effects of CS gas.

« There’s a tremendous under-appreciation of the dangers of tear gas, » said Fine in a telephone interview. « In my opinion it’s a misnomer to call this stuff ‘tear gas.’ It’s really poison gas . . . . « 

A team of four American physicians from Fine’s group who visited the West Bank and Gaza in February said in their report that they could not substantiate claims of an increase in the incidence of miscarriages due to tear gas. Even so, Fine warned, Israel should not take the safety of tear gas for granted.

« I have to question both the logic and the morality of what the Army surgeon general is saying, » said Fine. « It’s a double standard he’s applying here. Would Israel use the same gas on its own children? I don’t believe so. »

Persecution of Health Professionals | Persecution in Bahrain

Lien vers l’article

After the pro-democracy uprising started in Bahrain in 2011 as part of the Arab Spring, the government responded with a widespread, severe crackdown. Doctors in Bahrain, who had first-hand knowledge of government atrocities, quickly became a target after treating hundreds of protesting civilians. The Bahraini government systematically targeted medical personnel who treated, unbiasedly, wounded protestors. PHR went to Bahrain to investigate and document these attacks.

Our 2011 report Do No Harm, published following a PHR visit to Bahrain, presents forensic evidence that documents government attacks on physicians, medical staff, patients, and unarmed civilians with the use of bird shot, physical beatings, rubber bullets, tear gas, and unidentified chemical agents. Our 2012 report Under the Gun: Ongoing Assaults on Bahrain’s Health System shows the devastation on Bahrain’s health system that resulted from the Government of Bahrain’s continued assault on doctors, patients, and the health care system. Bahrain’s abuses in the spring of 2011 are the most extreme violations of medical neutrality in the past half century, and history will remember them as such.

PHR not only documented abuses against Bahraini doctors, but also began working on behalf of our medical colleagues in Bahrain in 2011. The data below tracked Bahraini physicians who were sentenced to prison starting in 2011. Following an international outcry, in-part led by PHR, draconian convictions of up to 15 years for baseless charges were in some cases reduced to months. While some doctors served their shorter sentences and were released, many continued to face difficulties in being reinstated to their jobs, reissuing their medical license and running their private practices. Hear directly from Bahraini medics and the systematic discrimination they faced in the country. Most of the doctors who were reinstated were demoted and stripped of supervising responsibilities. The main hospital in Bahrain continues to be under military control, with the Ministry of Interior continuing to exert pressure on all medical facilities, denying people treatment and arresting them from the hospitals. There has been no compensation or rehabilitation offered to the doctors who were subjected to torture, arbitrary detention and unfair trial.
