[Survey of alkylphenols in aquatic environment of Zhujiang Delta].
The summer contamination of dissolved nonylphenols (NPs) and octylphenol (OP) in surface water of Zhujiang estuary and other rivers of Zhujiang Delta was analyzed. The result reveals that NPs concentration in The Pearl River remains < 20-40 ng/L, apart from the NPs concentrations of the mouth of The Pingzhou Channel the mouth of The Shawan Channel and Hutiaomen reaching a higher level of 98.84, 129.82 and 164.98 ng/L respectively. The Lingding Sea and open sea surface water keep at a lower level with the NPs concentration of < 10-14 ng/L. In terms of OP concentration in The Pearl River, any other sampling location is below LOD 2 ng/L, except for Baiertan, the mouth of The Shawan Channel and Hutiaomen being 2.89, 2.44, 2.12 ng/L respectively and inside Macao harbor being the highest level of 8.54 ng/L. The OP concentrations of The Lingding Sea and open sea surface water are lower than LOD 1 ng/L.
