Body Burdens

Measurements of the levels of pollutants in children’s bodies provide direct information about exposures to environmental contaminants. Also, measurements in women who may become pregnant, currently are pregnant, or currently are breastfeeding provide information about exposures that potentially can affect conception, the fetus, and/or the developing child. These “body burden” measurements most often are taken from blood samples, but also can come from urine or hair.
