The short term exposure limit for airborne benzene is 5 ppm for 15 minutes. [90] These legal limits were based on studies demonstrating compelling evidence of health risk to workers exposed to benzene. The risk from exposure to 1 ppm for a working lifetime has been estimated as 5 excess leukemia deaths per 1,000 employees exposed.
The study is trying to identify the exposure of workers to a variety of chemicals linked to health problems contained in the oil and natural gas released during the accident, including benzene, ethylbenzene, toluene, xylene, and the chemicals contained in dispersants used during the spill. The team will look at long-term problems such as cancer ...
Long-term exposure — meaning a year or more —to benzene can cause “harmful effects on the bone marrow and can cause a decrease in red blood cells, leading to anemia,” according to the CDC ...
The major effect of long-term exposure to the chemical is on the blood, which can eventually lead to cancer, according to the CDC. In some studies of the effects on humans, it was discovered that ...
Studies have linked benzene exposure in the mere parts per billion (ppb) range to terminal leukaemia, Hodgkin's lymphoma, and other blood and immune system diseases within 5-15 years of exposure." [29] Fossil gas and oil naturally contain small amounts of radioactive elements which are released during mining. [30]
The World Health Organization has said there’s no safe level of benzene exposure when it comes to cancer risk. But benzene isn't the only worrisome chemical that comes from stoves, nor are the ...
Research has not found a link between low-level exposure to benzene through cosmetics and cancer, but breathing in high doses of benzene can cause some short-term side effects, like dizziness and ...
The AEGL values describe the expected effects of inhalation exposure to certain compounds (airborne concentrations in ppm or mg/m 3). Each AEGL is determined by different levels of a compound's toxicological effects, based on the 4 Ds: detection, discomfort, disability and death. There are three levels of AEGL-values: AEGL-1, AEGL-2 and AEGL-3. [2]
