Mustard Gas is a pale yellow, oily, highly toxic, volatile, liquid alkylating compound with a sweet to garlic-like odor that evaporates to a poisonous gas. Mustard gas is a vesicant that was first used in chemical warfare in World War I, but is now only used in small amounts in research studies . Introduction. Sulfur mustard (SM), or mustard gas (bis[2-chloroethyl] sulfide), is a nonspecific alkylating agent that primarily targets the skin, cornea, and respiratory tissues (see Fig. 1 for structure of SM and several related analogs that have been used to investigate its mechanism of action). Although responses to SM are tissue specific and dependent on dose, inflammation is an early Cited by: Sulfur Mustard. Sulfur mustard (C 4 H 8 Cl 2 S) is one of a class of chemical warfare agen ts known as vesicants because of their ability to form vesicles, or blisters, on exposed skin (see Figure ).During WWI, exposed troops described the odor of this agent as a stench like mustard or garlic, hence its Cited by: 2. The most widely reported chemical agent of the First World War was sulfur mustard, known as "mustard gas".It is a volatile oily liquid. It was introduced as a vesicant by Germany in July prior to the Third Battle of Ypres. The Germans marked their shells yellow for mustard gas and green for chlorine and phosgene; hence they called the new gas Yellow Cross.
The azo-mustard 4-di-2″-chloroethylaminoazobenzene-2′-carboxylic acid was found to be mutagenic in Drosophila melanogaster males. The mutagenic effect was found only in pre-meiotic germ cell stages and, of these, late spermatids were the most sensitive. Sterility or . Mustard gas, or sulfur mustard (Cl-CH 2 CH 2) 2 S, is a chemical agent that causes severe burning of the skin, eyes and respiratory tract. It can . It was our first experience of mustard gas. The men we took were covered in blisters. The size of your palm most of them. In any tender, warm place, under the arms, between the legs, and over the face and neck. All their eyes were streaming, and hurting in a way that sin never hurts. (4) In Guy Chapman was badly affected by a mustard-gas. Castor oil has numerous industrial and medicinal applications, and its demand is increasing by 3%–5% per annum. The demand for castor oil derivatives is growing as they are biodegradable, cheap, and readily available. India needs to maintain its position in the global market by fulfilling the demand of castor seeds and oil.
But the story of mustard gas didn’t end there. And it has a brighter ending than you might think. “In the middle of difficulty lies opportunity”- Einstein. Two decades later, with World War II looming, researchers on the side of the Allied Forces feared a repeat of the mustard gas attacks of the Great War. So they tried to create antidotes. Most of the mustard derivatives used to treat patients were developed from the late s through the s by replacing the sulfur in the mustard gas formula with nitrogen.

A very interesting action against poisoning by diquat and paraquat is the addition of an emetic agent in their formulations, wherein the additive acts rapidly in the body and causes the individual to regurgitate the pesticide before it performs its toxic action [38 - 40]. The main poisoning symptoms are dehydration resulting from vomiting.
