*Concentrations are in micrograms per liter (ppb) of total mercury added at 

 start of the experiment which were lethal to specified percentage within the 

 indicated time frame. 



and Stanbury, 1948; Corner and Sparrow, 1956; Gray, 1974; Gray 

 and Ventilla, 1973; Hunter, 1949; Lask et al., 1971); anion concen- 

 tration in the medium (Amend, Yasutake, and Morgan, 1969; Lask 

 et al., 1971); complexing agents in solution (Boney and Corner, 

 1959; Eisler et al., 1972; Nishikawa and Tabata, 1969; Tabata and 

 Nishikawa, 1969); presence of surface active agents (Calamari and 

 Marchetti, 1973; Eisler et al., 1972); rate at which mercury was 

 administered (Corner and Rigler, 1957; Gillespie, 1972; Horn and 

 Katz, 1946); temperature of the water (Amend, Yasutake, and 

 Morgan, 1969; Ballard and Oliff, 1969; Boney and Corner, 1959; 

 Clemens and Sneed, 1958; Jones, 1973; Lask et al., 1971; MacLeod 

 and Pessah, 1973; Portmann, 1968; Rodgers et al., 1951; Vernberg, 

 DeCoursey, and O'Hara, 1974; Vernberg and O'Hara, 1972; Vernberg 

 and Vernberg, 1972); seasonal differences, as distinct from tempera- 

 ture (Vernberg, DeCoursey, and O'Hara, 1974); dissolved oxygen 

 content (Amend, Yasutake, and Morgan, 1969); pH (Lask et al., 

 1971); and salinity of the medium (Binet and Nicolle, 1940; Boetius, 

 1960; Hunter, 1949; Jones, 1973; 1975; Olson and Harrel, 1973; 

 Pyefinch and Mott, 1948; Roesijadi et al., 1974; Schneider, 1972; 

 Vernberg, DeCoursey, and O'Hara, 1974; Vernberg and Vernberg, 

 1972). Biological factors modifying the mercury survival response of 

 marine organisms include: age of test organisms (Connor, 1972; 

 Green et al., 1976; Okubo and Okubo, 1962; Portmann, 1968; Reish 

 et al., 1976; Vernberg, DeCoursey, and O'Hara, 1974; Wilson and
