Distribution and divergent process of volatile phenols in bottom waters in Jiaozhou Bay

Abstract

Volatile phenols are a class of protoplasmic toxicants which have caused inevitable environmental problems in many sea areas. This paper analyzed the content, pollution level and distribution of volatile phenol in bottom waters Jiaozhou Bay in May, September and October 1983. Results showed volatile phenol contents ranged from 0.25~1.95 μg L -1 in bottom waters in the whole year, and were lower than Class I for volatile phenols (5.00 μg L -1 ) in National Standard of China for Seawater Quality (GB3097-1997). Jiaozhou Bay was very slightly contaminated by volatile phenols in 1983 under the impacts of vertical water's effect. Due to the flow rate was very fast in the bay mouth, in where were low value regions in different seasons in the bay mouth (0.25-1.50 μg L -1 ), indicated that there was a divergent process of volatile phenols in bottom waters
