Mustard gas or sulfur mustard are names commonly used for the organosulfur chemical compound bis(2-chloroethyl) sulfide, which has the chemical structure S(CH 2 CH 2 Cl) 2, as well as other species. In the wider sense, compounds with the substituents −SCH 2 CH 2 X or −N(CH 2 CH 2 X) 2 are known as sulfur mustards or nitrogen mustards ...
Sulfur mustard, commonly known as mustard gas, was used as a chemical weapon in World War I and more recently in the Iran–Iraq War. Sulfur mustard is a vesicant alkylating agent with strong cytotoxic, mutagenic, and carcinogenic properties. After exposure, victims show skin irritations and blisters.
Highly Toxic: a gas that has a LC 50 in air of 200 ppm or less. [2] NFPA 704: Materials that, under emergency conditions, can cause serious or permanent injury are given a Health Hazard rating of 3. Their acute inhalation toxicity corresponds to those vapors or gases having LC 50 values greater than 1,000 ppm but less than or equal to 3,000 ppm ...
Islamic State militants most likely used mustard gas, a banned chemical weapon, against Kurdish forces in Iraq. Exclusive: Watchdog to probe alleged mustard gas use by Islamic state Skip to main ...
Additionally, chemical burns can be caused by biological toxins (such as anthrax toxin) and by some types of cytotoxic chemical weapons, e.g., vesicants such as mustard gas and Lewisite, or urticants such as phosgene oxime. Chemical burns may: need no source of heat; occur immediately on contact; not be immediately evident or noticeable; be ...
A chemical weapon agent (CWA), or chemical warfare agent, is a chemical substance whose toxic properties are meant to kill, injure or incapacitate human beings.About 70 different chemicals have been used or stockpiled as chemical weapon agents during the 20th century, although the Organisation for the Prohibition of Chemical Weapons (OPCW) has an online database listing 35,942 chemicals which ...
The idealized combustion of mustard gas in oxygen produces hydrochloric acid and sulfuric acid, in addition to carbon dioxide and water: (ClC 2 H 4) 2 S + 7 O 2 → 4 CO 2 + 2 H 2 O + 2 HCl + H 2 SO 4. Bis(2-chloroethyl)sulfide reacts with sodium hydroxide, giving divinyl sulfide: (ClC 2 H 4) 2 S + 2 NaOH → (CH 2 =CH) 2 S + 2 H 2 O + 2 NaCl ...
An explosion destroyed two buildings and killed at least seven people in the Harlem neighborhood of New York City on Wednesday morning, and many are attributing the tragedy to natural gas.
