DATA OF GEOCHEMISTRY 

 Table 82. — Bromine and iodine content of river and lake waters 



(1934) is in better accord with the present information, 

 but even it may be too low. The data gathered by 

 Konovalov (1959) for the rivers of the U.S.S.R. yield 

 a mean figure for iodine of 7.2 ppb. 



In addition to the papers to which reference already 

 has been made, the interested reader may wish to con- 

 sult the following for additional information on the iodine 

 content of lakes and rivers: Bado and Trelles (1937); 

 Buydens (1951); Dzens-Litovskii (1944); Dragomirova 

 (1944); Jarchovsky and Pacal (1954); Grushvitaskii 

 (1938);Nicolaev and Segel (1947); McHargue (1943): 

 Shee (1940). 



The available data for the halogen content of river 

 water do not seem to justify any modification of the 

 estimate of the mean content of river water by Correns 



(1956): F, 0.26 ppm; CI, 8.3 ppm; Br, 0.006 ppm; and 

 I, 0.0018 ppm. 



BORON 



Some data for the boron content of lakes and rivers 

 are presented in table 83. Additional information will 

 be found in tables 18, 19, 23, 56, 60, and 72 in the general 

 analyses section, and in the earlier editions of this book. 

 There appears to be a substantial body of information 

 in Maldonado and Guevara (1950), which was not avail- 

 able for consultation. Tageeva (1943) and Glebovich 

 (1946) discuss the geochemistry of boron in the hydro- 

 sphere. The California water quality publications for 

 the years 1951-56 (Calif. Dept. Water Resources, 1956, 

 1957) contain many analyses for boron.
