Abstract
Concentration Changes of Ca, Cu, Li, Mg, K, Na, and Sr in the Hudson River, New York: NOTES
Burton P. Fabricand, Eugene S. Imbimbo, Mary E. Brey
ABSTRACT
The concentrations of Ca, Cu, Li, Mg, K, Na, and Sr at various points in the Hudson River and one of its tributaries during July 1965, have been measured along with the conductivity of the water. Ca, Mg, K, Na, and Sr all show a minimum in concentration about 130 km from the mouth of the river, as does the conductivity. The cleanup process necessary to account for this minimum may sharply reduce the contribution of dissolved ions to the 
ocean
. Concentration values in ppm averaged over samples taken from three points upstream from the minimum are as follows: Ca, 24.5; Cu, 0.01; Mg, 6.7; K, 1.2; Na, 15.7; Sr, 0.14. There is a large contribution to these elements from ocean
waters at least as far as West Point, New York, 90 km from the mouth. Upper limits on the concentrations of Cr, Co,
Fe, Pb, Li, Mn, Ni, and Rb were established.
