Bisphenol-A, a scary compound that has already contaminated us all

There has been increased press of late about Bisphenol-A, or BPA, and its potential effects on humans. While this compound has been in commercial use for more than 50 years, and it has been suspected of being hazardous to humans since at least the 1930s, it continues to be in pervasive use in food storage containers and leaches into our food and water. BPA was initially studied only in mega doses and those mega doses were found to be relatively safe. The new focus is on small doses like the ones we get when we drink a soda, eat canned soup or vegetables, or use reusable plastic water bottles. BPA acts as an endocrine disruptor and can mimic estrogen in your body. This has the potential to impact us in huge ways.

Some studies have found links to BPA levels and miscarriage in women. Others have found that pre- and postnatal exposure (in the womb and through baby bottles) can cause hyperactivity in children. Hormones are critical to our growth, development, and fertility. Exposure to excess amounts of hormones or their mimics can drastically alter normal growth and development. This is particularly true of developing fetuses and children who are naturally more sensitive to hormones than adults.

No one can say with certainty that BPA is not the cause of frightening trends in our health and well being. No one can say with certainty that it is not part of the cause of rising infertility rates. Prostate cancer, breast cancer, and early puberty are all likely candidates when looking for BPA’s effects. And what about autism? I don’t think that can be crossed off of the list either without extensive study.

The food industry has a lot to lose if BPA is declared unsafe. The EPA continues to base their rulings with regard to BPA on data that is 20-30 years old. Although some progress is being made, we have a long way to go before BPA stops leaching into our food and water.

Senator Carole Migden (D-San Francisco/North Bay) authored a bill (S.B. 1713) that would have removed from shelves all BPA containing products intended for children under the age 7. Unfortunately, that bill was defeated (31 ayes, 36 noes) in August. While that bill had its own flaws, it would have been a start at reducing our children’s exposure to this chemical.

As a nation, we consume vast quantities of bottled water. My office is one of thousands if not millions that provides a water cooler for its employees’ use. It is cool, refreshing, and convenient. The majority of my water intake each day comes from that cooler. The rest comes from a crock at home. Both use the big 5 gallon plastic jugs common to large water distributors such as Arrowhead and Sparkletts. Unfortunately, I just checked the number on the bottom of the Arrowhead bottle on my office cooler. Sure enough, it says that it is a #7 recyclable plastic, or polycarbonate. Polycarbonate leaches BPA. It does so at room temperature. It also does so continuously, so the longer something is stored in a polycarbonate bottle, the more BPA has been released into it. Furthermore, the amount of BPA released by a polycarbonate bottle increases as the bottle ages and as it becomes exposed to other chemicals such as cleansers. I do not know how Arrowhead cleans their big water bottles, but I am willing to bet that it involves sterilization through a combination of heat and chemicals. These processes can increase the amount of BPA that the bottles leach. So can scratches and other damage to the bottles. I also do not know how often the bottles get replaced. This is disturbing to me. In my attempts to drink more water and be more healthy, have I been feeding myself increased does of BPA? I certainly have.

I can’t wait to find out what the bottles at home say on them. They are likely the same. All of the water we use in cooking comes from those bottles. All of the water that is drunk by the humans and animals in my house comes from those bottles. And all of it is likely laced with BPA. On the bright side, it looks like I can replace the bottles at home with polyethylene bottles which are safer. Sadly, I can’t replace the one at the office. And that is where I drink most of my water.

This is frustrating because I do not see doing nothing as an option.

If you want to read more, you may find this article from The Green Guide interesting.

This article from GreenerPenny has some good information about alternatives to #7 and #3 plastics.

I have read some of the journal articles that all of this is based on too, but I don’t have those citations handy at the moment.  Sorry!

Digital Photo Archiving

Dear LazyWeb:

My wife and I have something like 4000+ photos that we need to scan (at high resolution) and archive, and be able to logically manage.

My platform choice is Mac. I will likely be purchasing a Mac Mini to dedicate to this task (2GHz model). I do not want to afford a Mac Pro, as awesome as it would be to have such a powerhouse in my home. I already have an Epson 2400 scanner, and would prefer to not have to replace it.

I have no idea what software to use for the resulting photo collection. I’d like something better than simple files on the disk, and am considering either Lightroom or Aperture, even both of those seem aimed more directly at digital photography.

I would like a simple workflow, if possible, that doesn’t rely on me naming the images. Tagging and notes/comments would be required.

Can I get away with Lightroom or Aperture, and whatever scanner software I can install for my scanner? Do I need something different?

Can Lightroom or Aperture store images on an external disk (which may not always be connected?) I’ve got plenty of storage already on my home network.


Hardware will likely end up being a new 13″ MacBook, instead of a Mac Mini, as my wife needs a replacement for her iBook anyway, and the new MacBook has way more power than the mini. This definitely necessitates the ability to store all the images on external storage, ideally via a network (SMB/CIFS) share.

Keys to the kingdom….

OOOOO…..shiny…..I just discovered that I too have the keys with which to unlock this site. Nifty. My husband must love me or something. *smirk*

Now if only I felt like I had more to say…..and more time. I’m stealing this time from work. SSSHHHH….don’t tell anyone!

I do have an oddity though…..okay, it’s odd to me. Maybe not to people who pay attention to how such things work, but it’s odd to me. I joined because Leticia wanted me to. I finally put up a pic last week or so. It’s probably my newest POIC (point of internet contact). (I love making up acronyms.) For some reason, that page is the one that comes up if you use google to look for me by first name and maiden name. Not anything else (at least on the first page of hits). Just that one. Even though it’s under my full last name. As are other things. This is very strange to me.

Do I like that random people from my past have been finding me? I don’t know. I suppose it shows that they care enough to try. 🙂 And I like finding out what people are up to. It’s just odd HOW they find me. Especially when my email address hasn’t changed since I left Bradley. Odd.
