Mercury In Breast Milk
Mercury in breast milk. Previous data on breast milk Pb and Hg contents are sparse or missing for the Austrian population. Mercury can pass from a mother to her baby through the placenta during pregnancy and in smaller amounts through breast milk after birth. Previous data on breast milk Pb and Hg contents are sparse or missing for the Austrian.
Exposure to mercury Hg and lead Pb may result in neurotoxic and nephrotoxic impairment and in anemia. How much and what types of fish are recommended for breastfeeding women to consume. The ultimate decision to breastfeed while taking medications should be based on an informed decision including available data discussions between a mother her.

Both metals appear in breast milk as a fraction of the levels found in maternal blood supplied to the fetus during gestation.
To diminish maternal and infant exposure to Hg and Pb it is necessary to establish guidelines based on an unders. The mean Pb content of breast milk was 163 Ϯ 166 gL. RESULTSThe mean Hg concentration of breast milk n ϭ 116 in the 3 Austrian cities was 159 Ϯ 121 gL Fig 1.
The amount of mercury in breast milk has been extensively studied because of concerns about transfer of the metal to the fetus 39. Total mercury concentrations mean - standard deviation in breast milk blood and hair samples collected 6 wk after delivery from 30 women who lived in the north of Sweden were 06 - 04 ngg 30 - 20 nmolkg 23 - 10 ngg 115 - 50 nmolkg and 028 - 016 microgg 140 - 080 micromolkg respectively. In addition many factors and parameters were related to the level of mercury contamination in breast milk.
It is excreted in breast milk from exposed mothers and may affect infant neuro-development. Fourteen of the 46 breast milk samples exceed 4mugl which is considered to be a high level. Cadmium levels in breast milk were the lowest with means.
Mercury and lead during breast-feeding Hg and Pb are of public health concern due to their toxic effects on vulnerable fetuses persistence in pregnant and breast-feeding mothers and widespread occurrence in the environment. It can also can pass to a nursing infant through breast milk.
Breast milk containing mercury exposes breast-fed infants to mercury Grandjean et al 1995.
The recommendations the InfantRisk Center provides are not meant to replace medical advice from your physician. Breastfeeding may also indirectly affect the metabolism of mercury in exposed infants by increasing elimination of the toxic metal Human milk contains many brain-protective substances including selenium glutathione vitamin E cysteine tryptophan choline taurine S100B protein sialic acid and polyunsaturated fatty acids. It is excreted in breast milk from exposed mothers and may affect infant neuro-development. Mercury can pass from a mother to her baby through the placenta during pregnancy and in smaller amounts through breast milk after birth. Exposure to mercury Hg and lead Pb may result in neurotoxic and nephrotoxic impairment and in anemia. How much and what types of fish are recommended for breastfeeding women to consume. Hg contents of breast milk and cow milk 112 Ϯ 056 gL. Mercury is a toxic metal ubiquitous in nature. Mercury and lead during breast-feeding Hg and Pb are of public health concern due to their toxic effects on vulnerable fetuses persistence in pregnant and breast-feeding mothers and widespread occurrence in the environment.
To diminish maternal and infant exposure to Hg and Pb it is necessary to establish guidelines based on an unders. Mercury levels in breastmilk are about one-third the level of mercury in the mothers blood. Pb stored in bone has a longer half-life than monomethyl-mercury acquired from fish. Previous data on breast milk Pb and Hg contents are sparse or missing for the Austrian population. Fourteen of the 46 breast milk samples exceed 4mugl which is considered to be a high level. Exposure to mercury can affect the infants brain and nervous system development during pregnancy and after birth. Mercury transporters have been described in human breast glands 40 and these could facilitate the transfer of mercury from the circulation into breast epithelial cells and secretions 41.
