How do you test for benzene in blood?
There is a test for measuring benzene in the breath; this test must be done shortly after exposure. Benzene can also be measured in the blood; however, because benzene disappears rapidly from the blood, measurements are accurate only for extremely recent exposures. Benzene exposure should always be minimized.How is benzene removed from the body?
Instead, try to cut off the clothing and remove it from your body as quickly as possible. Wash yourself and your skin with warm soap and water. Flush out any benzene that might be in the mouth or eyes for at least fifteen minutes.
Does benzene cause nerve damage?Benzene is suspected of causing nerve damage, blood disorders and cancer in humans, and genetic damage in laboratory animals.
