In some cases, samples that hadn't even been exposed to UV light also seeped estrogenic compounds."<br /><br />From http://www.motherjones.com/environment/2014/11/tritan-bpa-free-plastic-styrofoam-estrogen<br /><br />The follow-up study itself will soon be published in Environmental Health.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8964719845369935777.post-74490297082944764922014-09-11T13:12:05.976-04:002014-09-11T13:12:05.976-04:00The fact that the founder of a company that test t...The fact that the founder of a company that test the health hazards of other manufacturers plastics is ALSO the founder of a company that aims to develop (and sell) plastics with reduced health hazard is such a flagrant conflict of interest that its shocking that anyone would take his findings as objective and unbiasised.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8964719845369935777.post-59329025918923059292014-04-06T18:26:44.871-04:002014-04-06T18:26:44.871-04:00Not really, although the lawsuit went to trial and...Not really, although the lawsuit went to trial and the jury found in favor of Eastman: http://www.austinchronicle.com/news/2013-08-02/eastman-wins-jury-still-out-on-plastic/Chemjobberhttps://www.blogger.com/profile/15932113680515602275noreply@blogger.comtag:blogger.com,1999:blog-8964719845369935777.post-89180803460732680892014-04-06T03:26:51.795-04:002014-04-06T03:26:51.795-04:00Has there been any update to this debate?
