If you have an infant who never drinks tap water or formula made with tap water, a safe level of manganese in your water is 300 Âµg/L or less. If everyone in your household is more than one year old, a safe level of manganese in your water is 300 Âµg/L or less.
1. Manganese (Mn) is an essential trace element that is found in varying amounts in all tissues. Manganese concentrations are highest in tissues rich in mitochondria, where it forms stable complexes with ATP and inorganic phosphate. Manganese functions as a constituent of metalloenzymes and an activator of enzymes. key neurochemical alteration associated with manganese neurotoxicity is altered extracellular glutamate levels. Attenuated glutamate uptake by astrocytes has been invoked as the primary cause for this disturbance (Hazell and Norenberg, 1997 and Erikson and Aschner, 2002).
