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 ...
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 ...
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 ...
Beginning in the early 1930s, scientists at Rawalpindi sent British Indian Army soldiers, wearing shorts and cotton shirts, into gas chambers to experience the effects of mustard gas. The scientists hoped to determine the appropriate dosage to use on battlefields. Many of the subjects suffered severe burns from their exposure to the gas. [4]
The NOAEL could be defined as "the highest experimental point that is without adverse effect," meaning that under laboratory conditions, it is the level where there are no side-effects. It either does not provide the effects of drug with respect to duration and dose, or it does not address the interpretation of risk based on toxicologically ...
Examples include smoke or other poisonous gases at sufficiently high concentrations. It is calculated using the LD50 or LC50 . [ 1 ] The Occupational Safety and Health Administration (OSHA) regulation (1910.134(b)) defines the term as "an atmosphere that poses an immediate threat to life, would cause irreversible adverse health effects, or ...
In terms of tissue type, the body may be analyzed into water, fat, connective tissue, muscle, bone, etc. In terms of cell type, the body contains hundreds of different types of cells, but notably, the largest number of cells contained in a human body (though not the largest mass of cells) are not human cells, but bacteria residing in the normal ...
This chemical is a form of nitrogen mustard gas and a powerful vesicant. Historically, some uses of mechlorethamine have included lymphoid malignancies such as Hodgkin's disease, lymphosarcoma, chronic myelocytic leukemia, polycythemia vera, and bronchogenic carcinoma [ 7 ] Mechlorethamine is often administered intravenously, [ 8 ] but when ...
