DETERMINATION OF HUMIC SUBSTANCES IN SEAWATER AND ITS DISTRIBUTION IN THE CHANGJIANG RIVER MOUTH AND EAST CHINA SEA

Abstract:

This paper described a method for determining humic substances (HS) in seawater based on the UV-absorption. Using this method, the authors investigated the amount of HS in the seawater of Changjiang River mouth and East China Sea in. 1981-1983, Concentrations of HS in the surface layer seawater of Changjiang River mouth area west of 124°E vary from 150μg/1 to 435 μg/1. It was discovered that concentrations of HS decreased gradually from the estuary towards outer sea, that of HS in the surface layer seawater of East China Sea, area east of 124°E varied from 100μg/1 to 150μg/1,
