Household Bleach: Bad for the Environment?

May 24th, 2009

I’ve avoided bleach for sometime, but there are certain things that it’s just best for, such as whitening a stained white shirt, or cleaning up dirty grout in the bathtub. Was I bad for wanting a bottle of bleach? There’s a lot of massive anti-bleach hype on the Internet, but is it really that bad? I found an article that explains that bleach is not as bad as you might think. (Note: The first paragraph of this article has a typo in it. It should say, “household bleach does NOT pose a significant threat to the environment.”)

Small volume isn’t the only reason scientists are unconcerned about household bleach. Conditions in your laundry room are vastly different from conditions in a paper-bleaching plant, and as a result the household bleach behaves differently. “I am not aware of chlorine in washing machines causing significant hazards,” says Vern Snoeyink, Ph.D., a professor of environmental engineering at the University of Illinois at Urbana-Champaign. “We’re not aware of any significant problems with the bleach used in laundry, even at some of the bigger facilities,” says the IJC’s Bevaquah. “It’s just not a problem.”

Why isn’t it a problem? Scientists say that at least two major conditions are necessary to produce a long-chain organochlorine like dioxin, and they aren’t present in a household situation. To produce dioxin, the chlorine must have a low pH, and it must have a precursor (a set of carboncontaining molecules) to react with. The pH of household bleach is too high, says de Fur, and there are few, if any precursors available in the average load of dirty socks. In contrast, a paper-bleaching plant is packed with carbon-containing substances, and has a low pH. “I suppose you could throw a bunch of sawdust in the laundry,” speculates McCabe, “but even then you still couldn’t make dioxin.”

Now, this article is from 1995, but basic science does not change in 10 years. Household bleach breaks down to salt and water after being thrown down the drain. It is not the same thing as the bleach used to bleach toilet paper.

The problem with household  bleach is that making it can be harmful to the environment, but that can go for just about any product you buy these days. And of course, breathing in the fumes for a long period time isn’t good for you. But rather than being overly concerned with an occasional use of bleach, you are better off buying products that don’t use commercial bleaching, because that’s what really hurts the environment and pollutes. Buying recycled toilet paper that does not use chlorine bleach would be a good place to start.

The Lengths People Will Go To…

It seems that Americans still care more about convenience than the planet. A law banning phosphate-based dishwashing soap has led residents of Spokane to dash across state lines to smuggle in “bootleg” detergents:

Real estate agent Patti Marcotte of Spokane stocks up on detergent at a Costco in Coeur d’Alene, Idaho, and doesn’t care who knows it.

“Yes, I am a smuggler,” she said. “I’m taking my chances because dirty dishes I cannot live with.”

Because of course, in the hierarchy of American values, dirty dishes are oooh so much worse than the resultant dirty lakes and streams that result from phosphates.

In Search of a Natural Deodorant

August 10th, 2008

Tom’s of MaineI used to use conventional deodorant, but I was finding that each year, my brand (Lady Speed Stick) was ruining its scents by making them stronger and potent to the point of overwhelm. What happened to a simple baby powder smell? Yeesh. I was also getting concerned over the aluminum and other bad things, so I decided to give Tom’s of Maine deodorant a try.

I had tried Tom’s of Maine years ago and it was pretty useless. Now, however, they have added “hops” to the mix (yes, the stuff used in beer production). Apparently, this eats up bacteria, which is what makes your armpits smell.

Natural deodorants do not stop perspiration, so you have to be aware of that, but that’s a good thing. Blocking perspiration is probably not a good thing (some people think it may cause cancer)…because your toxic lymph isn’t allowed to sweat out. (more…)

CFLs: Damned if You Do…

March 25th, 2008

First incandescent bulbs were the enemy. Now CFLs are getting bad marks from the EPA for their mercury content. Are there any good light bulbs out there? Maybe we need to switch to soy candles or something…

New Dimming CFL Bulbs

January 14th, 2008

“CFL Bulbs” (compact fluorescents) are the new green light bulb – despite concerns over mercury in the bulbs. (I’ve also heard some rumblings of reports of people getting migraines from these bulbs..we’ll see.) These new CFL bulbs are now coming in new shapes and can even be dimmed. See:
