[QUOTE=staceychev;8736321]FWIW, according to this site there is little research on household cleaners and pregnancy. Also according to this site (take it for what it's worth, again), there was a study done that found a correlation between use of strong household chemicals during pregnancy and childhood asthma.http://www.pregnancy-info.net/risk_f...esticides.html
But that page doesn't say anything specific about bleach. It just lists bleach among a number of very different substances in a bulleted list at the bottom as "cleaners that you may want to avoid or at least approach with caution", without saying why.
|Also according to natural house maven Annie Berthold-Bond, sodium hypochlorite bonds with other chemicals in the wastewater stream to form organochlorines that may cause cancer and endocrine disruption. (from Better Basics for the Home, page 85). Please know that I'm not a chemist.
OK, please note that I am, but I'll try to keep it simple. I scarcely think that the household
use of bleach contributes significantly to any chlorine adduct problem, in that it's such a small volume and scattered use of the material compared to the vastly greater use of chlorinating agents in other applications, particularly pulp bleaching and water treatment. If you don't have your own well and septic tank, chances are that your water comes into your home chlorinated, and after going thru sewage treatment is chlorinated again before discharge, although I understand from someone in this thread that that practice is not universal.
Not only that, but it's not as if you could eliminate hypochlorite from your body or that of other living things. Human white blood cells and fungi produce hypochlorite to use as their own antibacterial agent.
Reminds me of how the demand of the state of Massachusetts to reduce medical formaldehyde discharge to 1 part per million looked when I found out human blood has about 3 parts per million formaldehyde.
