2024年9月6日 · Benzene is a colorless or light-yellow liquid chemical at room temperature. Signs and symptoms of benzene poisoning depend on how you were exposed. Get clean and get medical care if you were exposed.

Breathing benzene can cause drowsiness, dizziness, and unconsciousness; long-term benzene exposure causes effects on the bone marrow and can cause anemia and leukemia. Benzene has been found in at least 813 of the 1,430 National Priorities List sites identified by the Environmental Protection Agency (EPA).

Natural sources of benzene include volcanoes and forest fires. Benzene is also a natural part of crude oil, gasoline, and cigarette smoke. ToxFAQs - Fact sheet that answers the most frequently asked questions about a contaminant and its health effects.

When you are exposed to high levels of benzene in air, about half of the benzene you breathe in passes through the lining of your lungs and enters your bloodstream. When you are exposed to benzene in food or drink, most of the benzene you take in by mouth passes through the lining of your gastrointestinal tract and enters your bloodstream.

These clinics specialize in recognizing, evaluating, and treating illnesses resulting from exposure to hazardous substances. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for the hazardous substance described here.

2021年7月5日 · While two most concerning effects associated with systemic benzene toxicity are hematotoxicity and leukemogenicity, benzene is also a known direct irritant, causing skin, eye, and lung tissue irritation and damage.

Benzene is found in the air from emissions from burning coal and oil, gasoline service stations, and motor vehicle exhaust. Acute (short-term) inhalation exposure of humans to benzene may cause drowsiness, dizziness, headaches, as well as eye, skin, and respiratory tract irritation, and, at high levels, unconsciousness.

Benzene metabolism results in the production of several reactive metabolites that are thought to contribute to benzene toxicity. At low exposure levels, benzene is rapidly metabolized and excreted predominantly as conjugated urinary metabolites.

Motor vehicle exhaust and gasoline contain benzene, so if you breathe in contaminated air, particularly in areas with heavy motor vehicle traffic or around gas stations, you may be exposed to benzene. Inside your home, benzene can be released from gas stoves and ovens, and from fuel or wood-based heat sources such as fireplaces.

The ATSDR toxicological profile succinctly characterizes the toxicology and adverse health effects information for the toxic substance described therein. Each peer-reviewed profile identifies and reviews the key literature that describes a substance's toxicological properties.
