Abstract

Abstract

Vertical distribution pattern of nitrite and its influence factors were studied in Shenhu Area, South China Sea. The maximum of nitrite in concentration of 0.136-0.260 μmol·L^-1 appears within the depth between 75 to 100 meters, and in the other ranges, the concentration is less than 0.005 μmol·L^-1. However, there is no similar distribution patterns for either ammonium salt or nitrate. The distribution pattern of ammonium salt is not obvious, and nitrate increases with water depth. Further study of physical and chemical factors reveals that the distribution of nitrite is influenced by the concentration of ammonium salt, temperature, dissolved oxygen, acidity, organic content and others.
