I believe Elinda's point was that PVC piping is typically rigid (particularly for large municipal use) and thus doesn't require much in the way of phthalates which are used to keep the plastic soft at normal temperatures.
PVC used as a 'fabric' and the like would be a different story. But that's not much of a water leeching concern unless you have really weird pipes.
Let me try this again.
Cigarette smoke causes lung cancer.
Asbestos causes Mesothelioma.
Vaccines don't cause Autism.
Lead exposure causes brain damage in children.
PVA causes breast and testicular cancer, infertility, and probably causes emotional imbalances via it interfering with our hormonal systems.
No matter how rigid the water pipe.
You remember how they discovered most crude oil derived synthetics were endocrine disruptors? Because they thought that all this fish and animal infertility around lakes might be caused by leftover birth-contorl chemicals in women's urine. Except when they investigated that theory, they ruled the birth control out and the PVC pipes in, along with other plastic and petrochemical pollution. What does every oestrogen have in common? A benzine ring and being fat-soluable. What do most petrochemicals, synthetic plastics and synthetic fragrances have in common? A benzine ring and being fat-soluble. This isn't something to blank out of your mind because imagining a life without plastic is too hard. There are cheap and easy alternatives right now. There are a heap of plastics and synthetics that AREN'T endocrine disrupting. And the test to find out is simple and cheap. Welcome to the next Senate hearing. "Sir, when did you first know that there was a scientific consensus showing that the product you sell causes cancer and infertility?" Edited, Jul 11th 2013 3:58am by Aripyanfar
