A Mother's Day Question: What Do You Have in Common with Your Daughter...or Your Own Mother?
By Diane MacEachern on May 02, 2011
The words, “You look just like your mother!” have taken on new meaning in the chemical age in which we live. According to the nonprofit research institute Environmental Working Group (EWG), we mothers pass the pollutants that have built up in our bodies along to our daughters while they are still in the womb. Consequently, our daughters begin life with a “body burden” of potentially cancer-causing chemicals that continue to accumulate throughout life.
Chances are great that our daughters will pass on to our grandchildren some of the same chemical molecules they inherited from us. The estimated age by which a daughter will purge 99 percent of the inherited chemical varies depending on the chemical. It will take a day to excrete the phthalate plasticizers that soften up cosmetics, paint and plastics, but a year to dump mercury. Our daughters will be at least teenagers but perhaps senior citizens before they’re rid of the common flame retardants and stain-proofing chemicals we pass along. They would be 166 years old before they’re free of their inherited lead.
Meanwhile, their own body burden continues to increase. According to EWG’s test results, chemicals that persist in the body were found at higher levels in mothers than daughters, showing how chemicals can build up in the body over a lifetime. Mothers had an average of 1.5 to 5.2 times more pollution than their daughters for lead, methyl mercury, brominated flame retardants, and the Teflon- and Scotchgard-related perfluorochemicals PFOA and PFOS.
The EWG study, which was done on four mothers and their daughters, found that each of the eight women's blood or urine was contaminated with an average of 35 consumer product ingredients, including flame retardants, plasticizers, and stain-proof coatings. These mixtures of compounds found in furniture, cosmetics, fabrics, and other consumer goods, have never been tested for safety. The mothers and daughters in this study join 64 other people tested in six EWG biomonitoring programs conducted between 2000 and 2006. In total, EWG biomonitoring has found 455 different pollutants, pesticides, and industrial chemicals in the bodies or cord blood of 72 different people — including 10 newborn babies with an average of 200 chemicals in each child.
"EPA studies show that children from birth to age two are 10 times more sensitive to cancer-causing chemicals than adults," said Jane Houlihan, EWG's vice president for research. "Scientists have found that chemicals' toxic effects can be passed down for four generations, by causing permanent genetic changes that can be inherited. A stew of toxic chemicals is not the legacy mothers want to hand down to their children."
We monitor the pollution in our air, our water, and even our fish. Isn't it time we started paying attention to the pollution in our bodies?
