Percent of total Pb in chloride, hydroxide, and sulfide complexes as a function of pH-log conditions along the 0.001 ppm total Pb isopleth in Fig. 2. Specific pH-log conditions (pH, log ) are given in Table 6, along with corresponding % of total Pb values for various forms of Pb, and begin at the right end of the 0.001 ppm isopleth with data set #7 (8, -52.70), followed by #6 (6, -52.40), #5 (6, -53.55), #4 (6.45, -54.00), #3 (7, -54.60), #2 (7.3, -55.00), and #1 (7.55, -57.00).
