THE QUARTER NOTE
LEAD IN DRINKING WATER, Flint Michigan
The contamination of drinking water in Flint, Michigan, is a disaster of massive proportions. Considering the fact that children have been exposed from the time that they were conceived in the womb to their birth and development represents a template for numerous neurological and developmental problems. Exposure from drinking water consumed by the mother while the child is still in the womb coupled with direct exposure of the neonate via drinking water and foods cooked in contaminated water results in exposure during the most critical period of a child's development.
The first three years of life is a period of incredible growth in the neonate. By age 3, the brain has grown dramatically producing billions of cells and hundreds of trillions of connections, or synapses, between these cells. Many of these developmental processes can be altered by the presence of lead in brain tissue.
Thus, children are the most susceptible to the toxic effects of lead. Lead is passed from mother to fetus and neonate via transplacental transfer and mother's milk. From fetus to neonate to young child, lead is accumulated faster in children than in adults, resulting in serious neurobehavioral problems, delayed developmental effects, and mental retardation. Lead is distributed to the brain, liver, kidney, and bones. Lead also disrupts hemoglobin formation causing anemia. Currently, no safe level of lead in a child's blood has been identified, but a level of 5 µ/dl is considered a good guideline for maximum lead levels in children; however, there are scientific studies showing adverse effects at blood levels of less than 5 µ/dl. In assessing the potential causal relationship in lead cases, we must be certain of the source. In the case of contaminated drinking water in Flint, Michigan, there is no question of the source.
