What does MTBE do to humans?

What does MTBE do to humans?

Short-term health effects from high levels of MTBE in water could include nervous system effects, dizziness, headaches, nausea, and throat irritation. Kidney and liver effects, including cancer, have been seen in laboratory animals given high doses of MTBE over long periods of time.

Is MTBE a carcinogen?

EPA classified MTBE as a “possible” human carcinogen under its 1986 cancer risk assessment guidelines on the basis of results of inhalation cancer tests and has suggested that it be regarded as posing a potential carcinogenic hazard and risk to humans, though no quantitative estimate of the cancer potency of MTBE has …

Why is MTBE banned?

MTBE increases octane and oxygen levels in gasoline and reduces pollution emissions. Because of concerns for groundwater contamination and water quality, MTBE is now banned or limited in several states. MTBE is also used in small amounts as a laboratory solvent and for some medical applications.

Why is MTBE bad for the environment?

Movement and Disposition of MTBE in the Environment Because MTBE dissolves easily in water and does not “cling” to soil very well, it migrates faster and farther in the ground than other gasoline components, thus making it more likely to contaminate public water systems and private drinking water wells.

When was MTBE banned in the US?

2002
Background: Methyl tertiary-butyl ether (MTBE) was used as a gasoline additive in the United States during 1995-2006. Because of concerns about potential exposure and health effects, some U.S. states began banning MTBE use in 2002, leading to a nationwide phaseout in 2006.

How do you test for MTBE?

Though you cannot currently purchase a home testing kit, you can determine if your water contains MTBE the following ways. If your drinking water is supplied by a public water system, you can contact the system directly and ask whether they monitor for MTBE and what levels, if any, have been detected.

What is MTBE in drinking water?

MtBE is the abbreviation for the compound methyl tertiary butyl ether. MtBE is manufactured and thus its presence in water indicates that human-caused contamination exists in the recharge area of the well. MtBE degrades very slowly and is highly soluble in water.

Does reverse osmosis remove MTBE?

A WECO reverse osmosis water filter will remove MTBE along with heavy metals, pesticides, and other contaminants.

Who invented MTBE?

MTBE was first synthesized in the 1960s by researchers at the Atlantic Richfield Corporation (now ARCO) as an additive designed to increase the octane number (fuel efficiency) of gasoline.

Which countries use MTBE?

Key Market Trends The demand for MTBE in countries such as China, India, South Korea, Mexico, and Saudi Arabia, has been increasing due to increased demand for gasoline from the automotive industry with the growing number of on-road vehicles. This has been leading to an increase in demand for gasoline.

What countries still use MTBE?

U.S. exports of methyl tert-butyl ether (MTBE), a motor gasoline additive, totaled 38,000 barrels per day (b/d) in 2017, primarily to Mexico, Chile, and Venezuela. MTBE was once commonly used in the United States but was phased out in the late 2000s as a result of water contamination concerns.

How do I remove MTBE from water?

Unlike many other hydrocarbons, MtBE is difficult to remove from water. There are three treatment methods that are effective in removing MtBE from drinking water: air stripping, adsorption using activated carbon, and oxidation.
