1.🧵 about #Chemicalattack on school children in #Iran

Q1. What do we know?
A1. During the past month, several schools were allegedly attacked by unknown people. Hundreds of students suffered from different symptoms that vary from case to case.
#IranianSchoolgirls
2.
In the first attacks, all occurred in #Qom, students felt a smell like tangerine or "rotten tangerine" then they experienced symptoms varying from headache, dizziness, nausea, abdominal pain, difficulty to breathe & paralysis. The symptoms were recurring in some
3.
up to two weeks after the first incident.
It's said that the students were treated with atropine at the hospital.

Q2. What could be the cause of these attacks?
A2. Positive response to treatment with atropine, the smell of rotten tangerine, and paralysis point to one suspect.
4.
After a long discussion with many friends who prefer to remain anonymous and my knowledgeable colleague, @GawelPrzemyslaw, we couldn't find an ordinary chemical that satisfies our conditions for the cause of symptoms, smell, and positive response to treatment with atropine.
5.
The only suspect seems to be "soman" nerve agent. Please correct us if you are aware of other possible chemicals.
I must insist that at the moment, this is a mere speculation because we have no direct evidence at hand.

Q3. Is soman the only chemical used?
A3. Perhaps not.
6.
The description of the smell and symptoms in more recent attacks are different. Some of them match ClO that can be easily made by mixing bleach and an oxidizing agent.
Some reports may be an instance of mass hysteria as the paralysis is not reported, and the description
6.
of the description of the smell is vague, even different by different students at the same school. Distinguishing between the genuine incidents of #Chemicalattack and potentially mass hysteria is difficult, but the first cases seem to be very convincing.
7.
The teachers and paramedics were also affected in the first incidents. Although, it seems like they were less influenced because of their higher body mass.
Nevertheless, the government so far has been silent about the nature of the poison.
8.
Some officials blamed N2(!) or hydrocarbons as the cause of the #ChemicalAttacks and poisoning of the children, which are an utter nonsense.

۱. رشته توییت در مورد #مسمومیت_سریالی_دانش_آموزان مدارس

در مورد نشانه‌ها چه می‌دانیم؟
در مسمومیتهای سریالی بچه‌ها می دانیم بچه‌ها دچار تهوع، سرگیجه و فلج موضعی شده‌اند. در برخی موارد این فلج موضعی حتی پس از بهبودی دوباره بازگشته.
۲. بچه‌ها صحبت از احساس بوی میوه (نارنگی یا نارنگی گندیده) می‌کنند. بنا بر برخی اطلاعات بچه‌ها با آتروپین درمان شده‌اند.
نشانه‌ای از زردی پوست (یرقان)، آسیب ریوی یا آسیب کلیوی تا امروز گزارش نشده یا من از آنها بی اطلاعم.
چه موادی می‌توانند عامل مورد استفاده در حمله باشند؟
۳. فلج بدن، درگیری طولانی با عوارض و پاسخ مثبت در درمان با آتروپین نشانه استفاده از ترکیبات اورگانوفسفات است اما مسمومیت با اورگانوفسفات‌ها علایم دیگری دارد که من جایی آنرا ندیده‌ام. مثلا اورگانوفسفات‌ها باعث افزایش تعرق، رعشه، درد شکم و آبریزش بینی هم می‌شوند.

(۱) گاز تهوع آور Adamsite یکی دیگر از انواع گازهای متفرق کننده است. ظاهرا امشب از این نوع گاز در اطراف صادقیه استفاده شده. متاسفانه درمان آثار این گاز به سادگی CS نیست و کمک اهالی محل به معترضان ضروریست. آدامسایت گازی سبز-زرد است که هیچ پادزهر شناخته شده‌ای ندارد
روش درمان: Image
(۲) الف. به سرعت از محیط آلوده دور شوید.
ب. چشمها و پوست را با آب فراوان به مدت ۱۵ دقیقه بشویید.
ج. اگر بر اثر تماس با پوست آسیب دیدید پماد کالاندولا و سایر پماد‌های حاوی کالامین با حتی خمیردندان‌های حاوی منتول (اسانس نعنا) به شما کمک می کند.
(۳) د. در غلظت بالا یا در افراد آسيب‌پذیر آدامسایت سبب قطع تنفس می شود. آماده باشید که به مصدومان تنفس مصنوعی بدهید.
ه. اگر اختلال تنفسی زیاد باشد مصدومان نیاز به اکسیژن و بستری دارند.
و. قرقره کردن آب می‌تواند سوزش و خارش گلو را بهبود دهد.
