Garlic odor

Pale-yellow to dark-brown liquid with a faint odor like garlic. Odor becomes more pronounced during storage. This material is hazardous through inhalation, skin absorption (liquid), penetration through broken skin, and ingestion, and produces local skin/eye impacts. 

Observational studies that track disease incidence in different pop-(5°) ulations suggest that garlic use in the diet may act as a cancer-fighting agent, particularly for prostate and stomach cancer. However, these findings have not been confirmed in clinical studies. And yes, reported side effects include garlic odor. 

The olfactory receptors can be stimulated by bloodborne odors. Garlic odor, carried in the blood, can be perceived olfactorily (Maruniak etal., 1983). 

Yellow phosphorus burns spontaneously in air, and the vapor released is irritating to the respiratory tract. The early signs of systemic intoxication by phosphorus are abdominal pain, jaundice, and a garlic odor of the breath prolonged intake may cause anemia, as well as cachexia and necrosis of bone, involving typically the maxilla and mandible (phossy jaw). In chronic phosphorus intoxication, lowered potassium blood levels or increased chloride concentrations along with leukopenia have also been reported. ... 

In a study of workers in a selenium plant, workroom air levels ranged from 0.2 to 3.6mg/m and urinary levels ranged from below O.lOmg/1 to 0.43 mg/1 of urine. The chief complaints were garlic odor of the breath, metallic taste, gastrointestinal dismrbances, and skin eruptions. ... 

Toxicology. Tellurium causes garlic odor of the breath and malaise in humans. 

Serious cases of tellurium intoxication have not been reported from industrial exposure. Iron foundry workers exposed to concentrations between 0.01 and O.lmg/m complained of garlic odor of the breath and sweat, dryness of the mouth and metallic taste, somnolence, anorexia, and occasional nausea urinary concentrations ranged from 0 to 0.06 mg/1. Somnolence and metallic taste in the mouth did not appear with regularity until the level of tellurium in the urine was at least 0.01 mg/l. Skin lesions in the form of scaly itching patches and loss of sweat function occurred in workers exposed to tellurium dioxide in an electrolytic lead refinery. ... 

FORM Colorless gas with a strong garlic odor. 

Dangerously toxic by inhalation. Exposure can cause injury to lungs and liver pneumonitis, and strong irritant actions on skin, eyes, and mucous membranes. Other effects are garlic odor of breath, nausea and dizziness. A few minutes exposure to 50-100 ppm concentration of this gas in the air can be lethal to humans. LClo inhalation (rat) 20 mg/m /l hr. 

Garlic oil is obtained by steam distillation of crushed bulbs of the common garlic, Allium sativum L. it is a clear, reddish-orange liquid, with a strong, pungent, characteristic garlic odor. 

The threshold limit value (TLV) set by the American Conference of Industrial Hygienists (ACGIH) for tellurium and its compounds is 0.1 mg/m3 which is about ten times the amount which has been known to produce the adverse garlic odor (45,50). The ACGIH TLV for tellurium hexafluoride is 0.1 mg/m3 or 0.02 ppm of air. Likewise, the U.S. Occupational Safety and Health Administration (OSHA) has established its permissible exposure limit (PEL) for tellurium and its compounds at 0.1 mg/m3 the PEL for tellurium hexafluoride is 0.2 mg/m3 or 0.02 ppm of air (50). 

The resin of sagapenum has been examined by Johnston, who gives, as the representative of its composition, the formula C40 HSB Ot. It possesses a strong garlic odor, and easily fuses, becoming fluid at 212°, Ethar resolves it into two resins... 

Self-Test 4.10B The Codex Ebers, an Egyptian medical papyrus, describes the use of garlic to treat many ailments, including the cleansing of wounds. Chemists today have discovered that the oxide of diallyl disulfide (the volatile compound responsible for garlic odor) is a powerful antibacterial agent more potent against typhoid than penicillin. At 177°C and 200 Torr, a sample of diallyl disulfide vapor has a density of 1.04 g-L 1. What is the molar mass of diallyl disulfide ... 

The pharmacologic activity of garlic involves a variety of organosulfur compounds. The most notable of these is allicin, which is responsible for the characteristic garlic odor. 

White phosphorus particles can bum on the surface of the skin or penetrate deep into the tissues when carried on shrapnel particles. Local destruction of tissues continues as long as white phosphorus is exposed to oxygen. White phosphorus smoke with a garlic odor is characteristic of white phosphorus burns (Eldad and Simon 1991). High mortality rates seen... 

Colorless liquid with garlic odor bp50> 240°C.1... 

Sulfur is chemically similar to, but more diverse than, oxygen. Whereas, with the exception of peroxides, most chemically combined organic oxygen is in the -2 oxidation state, sulfur occurs in the -2, +4, and +6 oxidation states. Many organosulfur compounds are noted for their foul, rotten egg, or garlic odors, which makes them very unpleasant environmental contaminants, but warns of their presence even at very low levels. A number of example organosulfur compounds are shown in Figure 1.19. 

Methanethiol and other, lighter alkyl thiols are fairly common air pollutants that have ultragarlic odors both 1- and 2-butanethiol are associated with skunk odor. Gaseous methanethiol is used as an odorant leak-detecting additive for natural gas, propane, and butane it is also employed as an intermediate in pesticide synthesis. A toxic, irritating volatile liquid with a strong garlic odor, 2-propene-l-thiol (allyl mercaptan) is a typical alkenyl mercaptan. Benzenethiol (phenyl mercaptan) is the simplest of the aryl thiols. It is a toxic liquid with a severely repulsive odor. 

A typical alkenyl mercaptan is 2-propene-l-thiol, also known as allyl mercaptan. It is a volatile liquid (bp, 68°C) with a strong garlic odor. It has a high toxicity and is strongly irritating to mucous membranes when inhaled or ingested. 

Uses Pure fenthion is a colorless liquid. Technical fenthion is a yellow or brown oily liquid with a weak garlic odor. It is grouped by the USEPA under RUP and requires handling by qualified, certified, and trained workers. Fenthion is used for the control of sucking and biting pests (e.g., fruitflies, stem borers, mosquitoes, cereal bugs). In mosquitoes, it is toxic to both the adult and the immature forms (larvae). The formulations of fenthion include dust, emulsifiable concentrate, granular, liquid concentrate, spray concentrate, ultra-low volume, and wettable powder.28... 

Movies have depicted its power to repel werewolves and vampires. The characteristic garlic odor derives from the many sulfur compounds it contains. One of the major constituents is allicin, a compound with antibacterial properties.
