Selenium (Se) concentrations in sediments in
parts per million, dry weight (ppm) at 24 stations
sampled in February and August of 1997. * indicates
coarse sediment stations. Selenium concentrations
ranged from 0.04 to 0.54 ppm The highest concentration
was sampled at San Joaquin River (BG30) in February
and the lowest at Davis Point (BD41) in February.
Average concentrations were highest (0.42 ppm) in
the Southern Sloughs in August and lowest (0.07
ppm) in the Rivers in August. There are no ERM and
ERL values for selenium. |
