How many ppm of benzene is dangerous?

Because benzene can cause cancer, NIOSH recommends that all workers wear special breathing equipment when they are likely to be exposed to benzene at levels exceeding the recommended (8-hour) exposure limit of 0.1 ppm.

Substance: Benzene. Airborne: The maximum time-weighted average (TWA) exposure limit is 1 part of benzene vapor per million parts of air (1 ppm) for an 8-hour workday and the maximum short-term exposure limit (STEL) is 5 ppm for any 15-minute period.

Additionally, how long does benzene stay in your system? If benzene enters the body it may be temporarily stored in your bone marrow and fat but will quickly be metabolised (broken down) by the liver. Some of these metabolites also cause harmful effects and most leave the body in the urine within 48 hours.

Then, how much benzene can kill you?

Brief exposure (5–10 minutes) to very high levels of benzene in air (10,000–20,000 ppm) can result in death. Lower levels (700–3,000 ppm) can cause drowsiness, dizziness, rapid heart rate, headaches, tremors, confusion, and unconsciousness.

How do you limit the exposure of benzene?

Avoid skin contact with gasoline. When possible, limiting the time you spend near idling car engines can help lower your exposure to exhaust fumes, which contain benzene (as well as other potentially harmful chemicals). Use common sense around any chemicals that might contain benzene.

What drinks contain benzene?

The five drinks listed by the government were Safeway Select Diet Orange, Crush Pineapple, AquaCal Strawberry Flavored Water Beverage, Crystal Light Sunrise Classic Orange and Giant Light Cranberry Juice Cocktail. The high levels of benzene were found in specific production lots of the drinks, the FDA said.

Do Cigarettes contain benzene?

Benzene is a by-product of the combustion of tobacco in cigarettes. Exposure to cigarette smoke accounts for roughly half of all human exposure to this toxin in the United States. Benzene is extremely volatile. Smokers and non-smokers alike are exposed to benzene when they breathe in secondhand smoke.

What products contain benzene?

Products Containing Benzene Paint, lacquer, and varnish removers. Industrial solvents. Gasoline and other fuels. Glues. Paints. Furniture wax. Detergents. Thinners.

Do cars emit benzene?

“According to research, the dashboard of a car, sofa and air freshener emit Benzene, a cancer-causing toxin (carcinogen – take time to observe the smell of heated plastic in your car). In addition to causing cancer, Benzene poisons your bones, causes anaemia and reduces white blood cells.

What type of cancer does benzene cause?

Benzene is a cause of acute myeloid leukemia (AML) and myelodysplastic syndrome and a probable cause of other hematological malignancies, such as non-Hodgkin lymphoma (39–41).

What happens if you drink benzene?

Eating foods or drinking beverages containing high levels of benzene can cause the following symptoms within minutes to several hours: Vomiting. Irritation of the stomach. Dizziness.

Can Benzene be absorbed through the skin?

Benzene is a highly volatile, flammable liquid. Its vapor is heavier than air and may accumulate in low-lying areas. Benzene is absorbed rapidly and extensively after inhalation and ingestion. It is absorbed less extensively through intact skin; however, percutaneous absorption may contribute to total body burden.

What does benzene smell like?

Benzene has a sweet, aromatic, gasoline-like odor. Most individuals can begin to smell benzene in air at 1.5 to 4.7 ppm. The odor threshold generally provides adequate warning for acutely hazardous exposure concentrations but is inadequate for more chronic exposures.

Can you drink benzene?

Eating foods or drinking liquids containing high levels of benzene can cause vomiting, irritation of the stomach, dizziness, sleepiness, convulsions, rapid heart rate, coma, and death. The health effects that may result from eating foods or drinking liquids containing lower levels of benzene are not known.

Where is benzene found in the home?

Benzene is produced naturally by volcanoes and forest fires. In homes, benzene may be found in glues, adhesives, cleaning products, paint strippers, tobacco smoke and gasoline. Most benzene in the environment comes from our use of petroleum products. Benzene quickly evaporates from water or soil.

Is benzene a hydrocarbon?

Benzene is an organic chemical compound with the chemical formula C6H6. The benzene molecule is composed of six carbon atoms joined in a ring with one hydrogen atom attached to each. As it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon.

How do you remove benzene from water?

Benzene can be reduced below 5 ppb in drinking water using granular activated carbon filtration or packed tower aeration. Work with a professional engineer to determine the best treatment for your system. Not all kinds of treatment are effective, and no single treatment method can remove all contaminants from water.

Why is benzene carcinogenic?

Because benzene is a volatile aromatic solvent, inhalation exposures predominate. The carcinogenic properties of benzene have long been recognized; an increased risk of leukemia has been shown in workers exposed to high levels of benzene. Benzene exposure is associated with myelodysplastic syndromes.

Does paint cause cancer?

Paint Exposure May Increase Cancer Risk. Occupational exposure to paint may cause an increased risk of cancer, according to a new study published in the March issue of the Journal of Occupational and Environmental Medicine.
