Endocrine Disruptors in Bottled Water

Why Endocrine Disruptors In Water Are Dangerous To Health

Endocrine Disruptors in Bottled Water

The Endocrine Disruptors in bottled water people are drinking today will have far reaching health consequences tomorrow.

Single use bottled water might be one of the most popular products in the modern world; a staggering one million water bottles are purchased every minute! [1]  

Researchers have discovered that the chemicals used to make plastic water bottles contaminate the drinking water and, they are toxic. 

Two chemicals used to make plastic bottles strong, flexible and transparent are phthalates and bisphenols (BPA

These chemicals are Endocrine Disrupting Compounds, -EDCs.

Other EDCs found in plastic bottles are polybrominated diphenyl ethers (PBDE) and tetrabromobisphenol A (TBBPA)2.

Because these chemicals are not chemically bound to the structure of the plastic they transfer to the bottled water.23 

Why Endocrine Disruptors are Toxic

Our endocrine system is a communications network regulated by hormones that are chemical messengers that tell the body what to do.

Phthalates, Bisphenols, PBDE, and TBBPA have similar chemical structures to our body’s hormones .2 

Because the chemical structure of the EDC’s is similar to our hormones they will interact and interfere with the endocrine system effecting growth, development, metabolism, and even alter DNA.2  

The Health Risks Endocrine Disrupting Compounds

Because the endocrine system plays a crucial role in the development of babies and young children, EDCs can cause severe developmental problems for this vulnerable age group.

EDCs have been linked to miscarriages and decreased cognitive and physical function in young children, and even ADHD.5,78 EDCs can also interfere with puberty.8 

Research shows that pregnant women and young children, almost without exception, are exposed to endocrine disruptors daily and that we are only beginning to realise the long term consequences.8

For adults the long-term exposure to EDCs leads to a increased risk of obesity, sterility and cancer.39 

There is also evidence EDCs are damaging the  reproductive genes in cells that then effects fetal development, and those consequences extend to adulthood. 

Toxic water

What we are exposed to today will have consequences on our health tomorrow.  

Regulations, Yes. But not Enforceable!

In the U.S., the guidance for the amounts of phthalates in bottled water are set by the Food and Drug Administration (FDA) but is not enforceable.10 

The level set for one kind of phthalate, DEHP, is 0. 006 mg/L.10 The FDA has not set a level for bisphenols such as BPA in food and water packaging.11 

Despite the evidence that EDC’c have detrimental to health the FDA deems the current levels of BPA found in food and beverage packaging to be safe.11

There are moves to create bottles without one of the most well-known bisphenols, BPA and you may have seen products advertised as “BPA free”. However, it’s worth noting that the alternate chemicals used are typically a bisphenol compound too.6

Bisphenols are a family of chemicals that have similar structures and properties, so don’t let the label fool you into thinking the product is better, you still have endocrine disruptors in bottled water and other plastic containers.46 the


The evidence is continues to gather that the endocrine disruptors in bottled water are are causing various negative health effects in people of all ages. While it’s extremely difficult to avoid all EDCs we can start by avoiding plastic water bottles.
