How do you measure phthalates?

Phthalate metabolites are measured in urine samples obtained from individual survey participants. ages 6 to 17 years varied between 45 μg/L and 62 μg/L, and was 45 μg/L in 2007–2008. From 2007–2008 to 2013–2014, the median level of DEHP metabolites in urine of children ages 6 to 17 years decreased to 16 μg/L.

Many companies have voluntarily removed phthalates from their products.

What are the properties of phthalates?

The phthalates have a clear syrupy liquid consistency and show low water solubility, high oil solubility, and low volatility. The polar carboxyl group contributes little to the physical properties of the phthalates, except when R and R’ are very small (such as ethyl or methyl groups).

Do all plastics contain phthalates?

Weirdly, not all soft plastic contains phthalates. Most plastic wraps, water bottles, and food containers are phthalate-free.

What is phthalate used for?

Phthalates are a group of chemicals used to make plastics more durable. They are often called plasticizers. Some phthalates are used to help dissolve other materials.

How long do phthalates stay in your body?

As phthalates are thought to have a relatively short half-life of less than 5 hours, this widespread detection is likely to indicate chronic exposure [15], rather than accrual within the body. Sources and pathways of exposure may vary widely.

What water filter removes phthalates?

Granular activated carbon (GAC) filters or nano-filtration systems filters will remove/reduce DEHP, a phthalate used in water piping.

What are the physical properties of phthalates?

The phthalates have a clear syrupy liquid consistency and show low water solubility, high oil solubility, and low volatility. The polar carboxyl group contributes little to the physical properties of the phthalates, except when R and R’ are very small (such as ethyl or methyl groups).

How many phthalates are in your urine?

CDC scientists measured 13 phthalate metabolites in the urine of 2,636 or more people aged 6 years and older who took part in the National Health and Nutrition Examination Survey (NHANES) during 2003–2004.
