I'm thinking of now switches from bottled drinking water to filtered. Would the filtered water be contaminated by BPA/BSA during the filtration process (Eg plastic Brita filtration jug)? Are our only options tap water and glass bottled water? It's so hard to find foods that havent been wrapped in plastic. This video also covers some of the negative impact of BPA on male sexual function.

The bigger the container, the higher the ratio of water to plastic.

You might get reverse osmosis water on tap, to fill in glass jars.

Sucks that most filters are made with plastic! I need to find ways to avoid this stuff! RO water is good but out of reach for the moment. Doesn't it need to be reconstituted with minerals and electrolytes?

What does it take for the BPA or BPS to leech into the food/water though?

 

Acid? Heat? Microwave? RO water is 'empty' however and water being a nice solvent will try to balance itself out such as the carbon dioxide in the air turning it a little acidic.

 

But RO filters also have plastic tubing that supply water to the tank and tap. I have the Wellness one and then it goes into another system to reminerlise the water so that it's better to drink but it still goes through plastic tubing though. I'll have to check what kind of plastic.

 

But if the BPS is more 'stable' and in the situations where you would use it (such as only for cold drinking water) and then immediately consumed then while not as 'ideal' as something like glass is it a problem to drink from it.

 

I iknow baby bottles where people would sterlise by steam or microwave you would not want to have BPA. I insisted on only using glass bottles for mine. :)

This study found that just three days on a BPA free intervention significantly decreased levels: http://www.ncbi.nlm....les/PMC3223004/

 

Food packaging containing BPA had to be avoided and yes hot and cold temperature extremes increase leeching.

 

"Bisphenol A (BPA) is a high-production- volume industrial chemical used in the manufacture of polycarbonate and other plastic products and epoxy resin–based food can liners. It is present in both canned and plastic-packaged foods sold in the United States (Schecter et al. 2010). Exposure is widespread, with detectable levels in urine samples from > 90% of the U.S. population (Calafat et al. 2008)."

[...]

"...canned foods and beverages and restaurant meals were the most likely sources of exposure to BPA and DEHP in their usual diets, because participants reported limited use of polycarbonate water bottles, frozen prepared foods, and microwaving in plastic."

[...]

"Exposure to PVC film, commonly used in food storage at home and in restaurants, may be another important exposure source, because these films are known to contain BPA and DEHP (Lopez-Cervantes and Paseiro-Losada 2003; Petersen and Jensen 2010)"

Apparently Brita uses polypropylene which doesn't contain BPA, I'm not sure about othe BPs like BPS though...
