A word on BPAs! Most everyone has heard about the risks posed by bisphenol-A, or BPA, a chemical found in many plastics (including bottles, pacifiers, plastic dishes) which interferes with or even mimics certain hormones found in our bodies. Well, a
new study reported in
Time suggests that many if not all plastics--even "BPA-free" ones!--may leach hormone-disrupting chemicals.
Oh, I turned out fine, what's all the fuss? Well, read
this article, also published in
Time. There is far too little regulation of the plastic industry, and consequently, far too little research done on the effects of plastics on our health. Take this powerful 1-2 punch
from the article:
"If you want to market a new drug, you need to convince the FDA — in multiple tests, over the course of years — that it won't cause serious harm. If you want to sell a new pesticide, you need to prove the same thing. The burden of proof is on manufacturers to make the grade, and government regulators are the final judge.
But if you want to market a new chemical for use in a product — even one that will come into contact with children or pregnant women — it's up to the EPA to prove that it's unsafe, using whatever data are provided by the chemical company, with little power to ask for more. And if it's one of the 62,000 chemicals that were already in use when the TSCA went into effect in 1976 — a category that includes BPA — chances are it was never really tested by the government at all. "Chemicals are deemed safe until the EPA can prove that they are dangerous," says Richard Wiles, executive director of the nonprofit Environmental Working Group. "It's completely backward."
Here is my new plastics rhyme, based on the numbers found on the bottoms of almost all plastic containers (which, by the way, do NOT indicate that they can be recycled, only that they belong to a particular class of plastics). I was getting annoyed that I couldn't remember what was "safe" and what wasn't.
1 and 2 try not to reuse
3's chlorine and nerve gas
4 and 5 are a.o.k.
but try to use fabric or glass!
Some rhyme, huh? :) Here is the deal (based on +/-10 million articles): When you reuse 1 and 2 (water bottles, milk and juice jugs, etc), especially when you use hot water to clean them, you are increasing the chance that hormone-like chemicals--chemicals that can interfere with growth or harm reproductive function-- will leach into the water or food you store in them. In addition, their production can create toxic byproducts, which often end up in our environment.
I have decided that I will NEVER use number 3 (polyvinyl chloride) plastics. They not only can leach powerful carcinogens into food and water, but their production also releases toxic amounts of chlorine (okay, not nerve gas, but it works for the rhyme!) that can kill wildlife. Many plastic wraps contain number 3 plastic! Nor will I ever use number 6 plastic (polystyrene, or styrofoam), which contains brain-damaging styrene (read
more).
Number 4 plastics are safer for longer-term use, but in some instances have been shown to leach hormone-like chemicals. Number 5 is the only plastic that seems not to leach much. However, read
here! Apparently, some researchers identified estrogen in their experiments, even though they weren't using any in their experiment. Where did it come from? The only plausible explanation: the plastics being used in the experiment (number 5s). Sadly, I live in an age where plastics are so ubiquitous I just can't avoid them all.
Here are the names of the plastics (awful ones crossed out!):
#1 is PTE (PET) or polyethylene terephthalate
#2 is HDPE or high-density polyethylene
#3 is PVC or polyvinyl chloride -- found in many plastic wraps!
#4 is LDP or low-density polyethylene
#5 is PP or polypropylene
#6 is PS or polystyrene--styrofoam containers and cups!
#7 is mixed. It could be a plastic not listed above, could be a mix or 2 or more.
It could be, for example,
polycarbonate (PC), which until very recently was used to produce Nalgene bottles. PC is NOT GOOD for you since it contains BPAs.
That is the end of my tirade. Okay, not quite. Do I use plastics? Yes, it's inevitable. I am trying to switch to glass for food. For now, I use only number 5's for food storage ONLY--never for reheating. For that, I transfer to a glass bowl. If only pyrex were less expensive! Also, I am throwing OUT my old nalgene bottles (apparently, new ones are available, don't know more than that). And though I have never bought bottled water, I am not planning to start now. And, I have sadly had to give up reusing old gatorade bottles for drinking water. I am still using old juice bottles for water storage, since I only washed them once and am not planning on reusing much, only replacing the water every 6 months or so.
