doing quick research while dd is napping
"lead does not concentrate in breast milk because it does not attach to fat; indeed, levels of lead are generally higher in a mother's blood than in her milk. Several studies have found higher blood lead levels in formula-fed infants than in breast-fed infants.
Much of the lead in breast milk does not come from the mothers' exposure during lactation. Instead, it comes from lead stored in the mothers' bones. Because lead mimics the beneficial mineral calcium, it is stored for decades along with calcium in the bones. During pregnancy and lactation, a woman's body extracts calcium from her own bones to provide calcium for her child's bone development. Calcium extraction from bone is greatest during lactation, and as a result, lead stored in the mother's bones also enters the blood and breast milk during pregnancy and lactation, posing an exposure risk to the fetus.14 A study in April 2003 confirmed that ensuring adequate dietary calcium intake or taking a calcium supplement before pregnancy, during pregnancy and during the entire lactation period decreases the blood lead level in lactating women. Supplemental dietary calcium most likely decreases the amount of calcium and lead that comes out of the mother's bones. Therefore, women can significantly reduce their baby's exposure to lead by getting adequate dietary calcium or taking a calcium supplement during pregnancy and lactation."
"it has been known for some time that breast feeding also stimulates the release of lead that has been stored in bone tissue.
The authors of the study concluded that breast milk lead levels were directly related to bone lead levels; but they emphasize that the benefits of nursing outweigh the risks associated with lead exposure stating, “It has been shown that lead levels in infant formula are greater than concentrations of lead in breast milk.”
"There is much controversy over how much lead is in breast milk, however, experts all agree that breastfeeding should continue unless there has been severe lead poisoning diagnosed in the mother during her life. Artificial baby milks and cow's milk also contain lead. Reducing your exposure and continuing to breastfeed is the most effective way of limiting your baby’s risk of lead exposure.
How much lead is there in breast milk?
Because breast milk is an ever changing substance, it can be difficult to measure and the literature shows a wide range of results. There has also been the problem of contaminated specimens. What has been found, is that the lead levels in breast milk are related to the lead levels in a mother's blood, but breast milk contains only 5% or less of this amount. Having your blood level checked is a simple way of estimating the risk to your baby.
I guess the bigger question is how this lead poisoning will effect my daughter when she breastfeeds her baby.
I got the results from her latest test back this morning. It went up, not good.
The progression has been 31, 30, 25, 21, 19, 16, 16 and now 17.
Between the 31 and 16 was when I sealed all the windows shut and cleaned like a maniac. Between the two 16s was when the lead abatement was done. I was upset that it did not change during those three months but I was not too worried since all that work was done. But now, months after our house is supposed to be lead-free.....aaarrrgggg!!! I have a call into the nurse at the health department that has been helping us. My first thought was maybe my bmilk. I have never been tested, but after doing this bit of research it seems that I would have needed to be lead poisoned as a child with my nusing now leaching the stored lead from my bones out into my milk.
Will keep you all posted as I learn how this increase could have happened.
oh, my baby....it was supposed to have gone down, now we have to wait more months til the next test...
Fedup, not sure if i can handle your answers right now, but what kind of problems is your son having? What was your progression down from 22 like? It is zero now... right?
Djwratha, I just looked through my "lead folder" and saw that I was able to rent the hepa vac from the county's planning and zoning dept. not sure why it is there, but worth checking your county's.
jrayn, for me everything with the health dept happened pretty fast. just keep at it. later, trying to get a grant for the work to be done, I had to call consistently and even sent in a picture of my adorable dd, so that these guys behind the desk would see that we were not just some numbers. be a fierce mama squeeky wheel.
more hugs to us all
