Well there is evidence that BPA is harmful but you are right that we still donīt know how much of BPA is harmful. And if scientists doing these studies are not sure and need more data how come you all already know that itīs just a scare?

At the end of the day you just said what I am trying to say: we donīt know enough yet. So we canīt label it as a "scare".

Blast:
You are right, it doesnīt look too dangerous indeed.

What if itīs confirmed that BPA accumulates in the body for a long period of time?:

The research indicates for the first time that people are either constantly being bombarded with bisphenol A from non-food sources, such as receipts and plastic water piping, or they are storing the chemical in fat cells, unable to get rid of it as quickly as scientists have believed.

My opinion is that there is still a lot to discover before we can say whether BPA is dangerous in those rations or not. And why unnecessarily increase the intake of BPA when you can use non-BPA products?

--

While some scientists say itīs nothing to worry about a lot of them rather tend to warn people because they donīt know enough yet. Or they say that they are not sure. And I donīt really think they are just trying to scare people.

"We don't know what a safe level of BPA is, so pregnant women should avoid BPA exposure," Taylor said. "There is nothing to lose by avoiding items made with BPA&#8212;and maybe a lot to gain."

&#8220;BPA is just one of many estrogen-like chemicals people are exposed to, and scientists are still trying to figure out how these endocrine disruptors&#8212;including natural phyto-estrogens from soy which are often considered healthy&#8212;collectively impact human health,&#8221; he says. &#8220;But a growing body of scientific evidence suggests it might be at the cost of your health.&#8221;

Please keep in mind that in a perfect world science would be devoid of politics. However, in the real world science and politics are intimately related. Studies supported by industry are often touted as being tainted due to the self-interest of the industry. Public perception is that studies performed by government, academic or institute scientists are devoid of politics and can be trusted more than those sponsored by industry. Nothing can be further from the truth; government, academic and institute scientists must compete for funding and/or grants. The lifeblood of science is funding and “creating” controversy is a guaranteed way to ensue your funding will continue.

Partisan politics also plays a significant role in influencing scientific inquiry. A scientist, whose scientific interests or views are consistent with the particular partisan entity in power, will receive greater funding than one who does not. A scientist who does not publish is doomed, if the study does not reveal some “potential” for public health concern, they have little to publish and funding will dry up quickly.

While, at this point in time, one can not totally dismiss the potential for BPA to have some negative (might also have some positive) effects on the body, the quantities that an individual is exposed to, through the use of polycarbonate bottles is so minuscule when compared to other naturally occurring BPA-like chemicals, that the “risk” from water bottles is totally overblown.
