The contents of Se in sea waters of Ise, Mikawa bay and river waters in Aichi prefecture were researched and the followings were concluded. 1) The Se contents of sea waters ranged from 0.01 to 0.15 ppb (average 0.07) and river waters from 0.02 to 0.28 ppb (average 0.08). The Se contents of most samples of sea waters were higher than those of river waters. 2) There was good correlationship between Se and SOsub(4)sup(2-) on river waters. 3) The background content of Se was found to be 0.02 to 0.04 ppb on river waters. 4) There was good correlationship between Se and BOD (less than 5 ppm) on relatively unpolluted river waters.
