Abstract: & total atmospheric PE input flux of 7 ng Pb cm/sup -2/ yr/sup
~i/ was measured in the North Pacific Easterlies at Enewetak. Parameters
used tc measure this flux were ratio ef dry deposition flux te
precipitation flux; Pb//sup 219/ Fb in precipitation and seawater; /sup
2i0.Fb flux: washout factor: and Pb concentrations in air, rain, and dry
descsition deposits. Relations among these parameters estabilished at
Enewetak were used tc recempute and comfirm previcus estimates cf lead
