What is the Noael of benzene?

What is the Noael of benzene?

The data presented by Schnatter et al 2020 define a benzene LOAEC of 2 ppm (8 h TWA) and a NOAEC of 0.5 ppm (8 h TWA).

How can benzene be prevented?

For short-term exposure to high levels of benzene, the Centers for Disease Control and Prevention (CDC) recommends getting away from the source of benzene, removing any clothing that may have benzene on it, washing exposed areas with soap and water, and getting medical care as soon as possible.

How do you test for benzene exposure?

Blood counts of all components of the blood and examination of bone marrow are used to determine benzene exposure and its health effects. For people exposed to relatively high levels of benzene, complete blood analyses can be used to monitor possible changes related to exposure.

Why is benzene toxic?

It is also found in gasoline and the smoke that comes from cigarettes. Benzene poisoning can be lethal because it causes the cells in the body to work incorrectly. Benzene exposure can cause bone marrow cells to not produce red blood cells or it can can cause the white blood cells of your immune system to fail.

Is benzene lethal?

Inhalation of benzene vapor concentrations of 20,000 ppm for 5-10 minutes can be fatal to humans; death results from central nervous system depression (Clayton and Clayton, 1981).

How do you store benzene at home?

It should be stored in tightly closed containers in a cool, well ventilated area. Benzene vapor may form explosive mixtures in air. All sources of ignition must be controlled. Use nonsparking tools when opening or closing benzene containers.

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.

What is the action level for benzene?

0.5 ppm
Definitions. Action level means an airborne concentration of benzene of 0.5 ppm calculated as an 8-hour time-weighted average. Assistant Secretary means the Assistant Secretary of Labor for Occupational Safety and Health, U.S. Department of Labor, or designee.

At what levels is benzene harmful?

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.
