STUDY FINDS MORE THAN 24,000 CHEMICALS IN BOTTLED WATER: WHICH ONES ARE HARMING YOU?

Endocrine disrupting chemicals (EDCs) were discovered by German researchers, which could adversely affect development and reproduction, to be contained in 18 different bottled water products.

From all 24,520 suspect chemicals found to be present in bottled water, the one that showed consistent results and illustrated anti-androgenic and anti-estrogenic activity is di(2-ethylhexyl) fumarate (DEHF). Endocrine disruptors are the chemicals that can interfere with the hormone system. They are able to cause cancerous tumours, birth defects, cardiovascular disorders, metabolic disorders, and as mentioned earlier,  other developmental disorders.

This study was made from Martin Wagner and Jorg Oehlmann of the Goethe University Frankfurt, Frankfurt am Main, and Michael Schlusener and Thomas Ternes of the German Federal Institute of Hydrology. In their study, they have determined that bottled water could contain serious amounts of EDCs that should be a cause for concern.

They were using spectrometric simulation to narrow down their findings to DEHF as the only possible EDC giving rise to harmful activity. DEHF is also known as an anti-estrogenic compound, which means that another unidentified EDC must be present in the samples that showed anti-androgenic activity.

The authors employed a sensitive in vitro bioassay to characterize the total estrogenic burden leaching from plastics, including potential mixture effects and unidentified EDCs. Using a similar approach, a series of studies reported a widespread estrogenic contamination of commercially available bottled water. . . .

Here, we combine biological and chemical analysis to identify putative steroid receptor antagonists in bottled water. Most of the products were potently antiestrogenic and antiandrogenic in the bioassays. Nontarget high-resolution mass spectrometry pointed towards maleate and fumarate isomers as promising candidates and subsequently enabled the identification of di(2-ethylhexyl) fumarate. Because its concentration is too low to explain the observed activity, other compounds must contribute. However, further maleate/fumarate isomers are not only biologically active but structurally highly similar to phthalates. Hence, we speculate these compounds might represent a novel, so far overlooked group of EDCs.

An increasing number of in vitro studies reports the presence of EDCs in bottled water. With previous studies focusing on estrogenicity, the present work provides evidence for an additional contamination with steroid receptor antagonists. Using an optimized extraction procedure, we detected antiestrogens and antiandrogens in the majority of analyzed bottled water products. Moreover, the antagonist activity was very potent. An equivalent of 3.75 mL bottled water inhibited estrogen and androgen receptor by up to 60 and 90%, respectively. . . .

Bottled water from six different countries has been found to contain estrogenic, antiestrogenic, and antiandrogenic (this study), as well as androgenic, progestagenic, and glucocorticoid-like chemicals. This demonstrates that a popular beverage is contaminated with diverse-acting EDCs

What can we do?

The solution is simple. Just don’t drink bottled water! Apart from that, purchasing water filters that take out the chlorine and fluoride from your water are good alternative. They’re easy to find and, with a little research, can be relatively inexpensive. Just think about 24,000 chemicals chemicals you are putting into your body. I’m not saying all of them are harmful, but who would want to take that chance? It’s not uncommon for us to taste some of these chemicals within the water that comes from the plastic, especially if we leave the bottle in the sun for a period of time.
