1,4-Dioxane Widespread in Long Island Drinking Water 1,4-Dioxane is listed as “likely to be carcinogenic to humans,” with a Lifetime Cancer Risk Guideline for drinking water of 0.35µg/L (micrograms per Liter) by the U.S. EPA. The chemical has been linked to tumors of the liver, kidneys, and nasal cavity.

What kind of health risks does 1/4-dioxane pose to the public?
Acute (short-term) inhalation exposure to high levels of 1,4-dioxane has caused vertigo, drowsiness, headache, anorexia and irritation of the eyes, nose, throat, and lungs in humans. It may also irritate the skin.
Is 1,4-dioxane an emerging contaminant?
1,4-Dioxane is an emerging environmental contaminant and a probable carcinogen. The de minimis cancer risk level is exceeded at 7% of U.S. drinking water sites.
What is the EPA’s nonbinding health advisory limit for 1/4-dioxane?
between 0.35 and 35 μg/L.
The EPA has a nonbinding health advisory level for 1,4-dioxane in drinking water of between 0.35 and 35 μg/L.
What is dioxane according to the EPA what is the danger of dioxane in Ann Arbor’s drinking water?
carcinogenic
Dioxane is a toxic chemical that’s classified by the U.S. Environmental Protection Agency as likely to be carcinogenic to humans by all routes of exposure. It also can cause kidney and liver damage, and respiratory problems.
What does dioxin do to the body?
Dioxins are highly toxic and can cause cancer, reproductive and developmental problems, damage to the immune system, and can interfere with hormones. Dioxins are found throughout the world in the environment , and they accumulate in food chain s , concentrating mainly in the fatty tissue of animals .
How is dioxane harmful?
Short-term exposure to 1,4-dioxane
Breathing: 1,4-Dioxane for short periods of time causes irritation of the eyes, nose and throat in humans. Exposure to large amounts of 1,4-dioxane can cause kidney and liver damage. Accidental worker exposure to large amounts of 1,4-dioxane has resulted in several deaths.
What products contain dioxane?
Most often found in products that suds, like shampoos, shower gels, dish soaps, and laundry detergents. 1,4-dioxane has also been found in toothpastes, mouthwashes, deodorant, and hair dyes.
How do you get rid of 1/4-dioxane?
One prominent study published in Water Science & Technology showed that filtration systems containing granular activated carbon (GAC) can reduce 1,4-dioxane levels by approximately 50 percent, and combining GAC and reverse osmosis can achieve reduction rates up to 96 percent.
How do you filter dioxane?
Most in-home water filters, including activated carbon filters, don’t remove 1,4-dioxane effectively. Reverse osmosis filters are better, removing a significant portion of the chemical from tap water, but still fall short.
Does reverse osmosis remove dioxane?
Reverse Osmosis (RO) Membrane separation varied in its effectiveness for removing 1,4- dioxane, using spiral- wound type membranes. RO in combination with other filtration methods yields a more effective result rather than using a solitary RO treatment.
Is dioxane a VOC?
1,4-Dioxane is a volatile organic compound that is completely miscible in water. While the Henry’s Law constant for 1,4-dioxane is relatively low compared to many co-occurring VOCs, it increases significantly with temperature.
How do you remove dioxane from a reaction mixture?
Dioxane, DMF, DMSO, and THF reaction solvents are all readily removed by aqueous workup rather than distillation. Add reaction mixture to solvent such as ether and wash five times with water.
What is dioxane used for?
1,4-Dioxane is used as a stabilizer for chlorinated solvents such as trichloroethane and trichloroethylene. 1 It can also be an unintended contaminant of chemical ingredients used in consumer products including bubble bath, shampoo, laundry detergent, soap, skin cleanser, adhesives, and antifreeze.
How does groundwater treat dioxane pollution?
1,4-Dioxane is susceptible to chemical oxidation, and in groundwater it can be treated by activated sodium persulfate, ozone and peroxide, and modified Fenton’s reagent; however, sodium permanganate is not effective for 1,4-dioxane treatment (Chiang et al. 2016).
How does dioxane get into water?
Exposure to dioxins can come through: consuming food, especially animal fats, where dioxins have accumulated. drinking water where dioxins have settled or where there is contamination from industries.
How do toxins affect the human system?
When toxins damage your enzymes, they prevent the production of hemoglobin in your blood, which can accelerate aging. It also can lead to the failure of energy production and lower your protection against oxidated stress. Failure of these normal body functions increases your risk of diseases like: Cancer.
Are dioxins banned in the US?
In 1979, the EPA banned the manufacture of products containing Polychlorinated Biphenyls (PCBs) some of which are included under the term dioxin. Consumers should eat a balanced diet and follow the 2010 Dietary Guidelines for Americans. Each food group provides important nutrients needed for health.
What are the side effects of dioxin exposure?
Short-term exposure of humans to high levels of dioxins may result in skin lesions, such as chloracne and patchy darkening of the skin, and altered liver function. Long-term exposure is linked to impairment of the immune system, the developing nervous system, the endocrine system and reproductive functions.
What is Dioxane in shampoo?
1,4-dioxane is an expected contaminant from a process called ethoxylation, when ethylene oxide is added to other ingredients to make them less harsh.1,4-dioxane is most often found in products that suds, like shampoos, shower gels, dish soaps and laundry detergents.
Is dioxane a Pfas?
These unregulated contaminants, such as per- and polyfluoroalkyl substances (PFAS), and more recently, 1,4- dioxane, have captured the attention of the plaintiffs’ bar.Although the PFAS and 1,4- dioxane contaminants have many differences, some of their similarities are denominators for future mass tort litigation.
