Chemicals that may mimic estrogen

I was reading this article, and what I found interesting about it--something I didn't know--was that there is evidence that phthalates and BPA may mimic the estrogen hormone. I'm not so worried about the essential oils, but I am more concerned about the phthalates and BPA, and will be more diligent in avoiding these chemicals where ever possible, particularly since I have a little dude to raise.
