Hippuric acid has long been used as an indicator of toluene exposure; [14] however, there appears to be some doubt about its validity. [15] There is significant endogenous hippuric acid production by humans; which shows inter- and intra-individual variation influenced by factors such as diet, medical treatment, alcohol consumption, etc. [15] This suggests that hippuric acid may be an ...
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]
In 2011, the U.S. Department of Health and Human Services launched the Gulf Long-term Follow-up Study through the National Institute of Environmental Health Sciences. As the largest, most comprehensive study of long-term health effects from an oil spill, the GuLF Study will collect health data on cleanup workers and track them for at least 5 years.
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 ...
It poisoned the groundwater with high levels of dichloroethene, trichloroethylene, vinyl chloride and benzene, a Navy report released in 2000 said.The colorless chemicals can cause several ...
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 ...
As benzene is ubiquitous in gasoline and hydrocarbon fuels that are in use everywhere, human exposure to benzene is a global health problem. Benzene targets the liver, kidney, lung, heart and brain and can cause DNA strand breaks and chromosomal damage, hence is teratogenic and mutagenic. Benzene causes cancer in animals including humans.
The MATC can be applied to the results of an acute toxicity test to obtain a concentration that would protect against adverse effects during an acute exposure. An LC 50, or the concentration at which 50% of the organisms die during an acute toxicity test is used to derive a value called the acute to chronic ratio (ACR).
