厦门海域海上污染源对环境质量的影响

1998年，对厦门海域港口码头、船舶以及海水养殖等主要海上污染源进行了监测和调查。结果表明，港口、船舶排放入海的石油类达148．8t，远远超过工业污水中油的排放量；海水养殖排放的无机氮和地磷分别达538．4t和200．4t；P的排放量已超过生活污水，几乎与城市污水排放P的总量相当。海上污染源污染负荷比占12．3％，大于工业污水，已是污染物的主要入海途径之一，是影响厦门海域环境质量的一个不容忽视的污染强源。

Effect of pollution source at sea on environmental quality in the sea area of Xiamen

The pollution source at sea such as port, shipping and mariculture were monitored in 1998. The result shown that, the outflow discharge of oils from port and shipping was 148.8t, and far exceeded that from industrial sewage. The DIN and DIP outflow discharges from mariculture were 538.4t and 200.4t, respectiveliy. Especially, DIP exceeded that from the domestic seage and was close to that from urban sewage. The pollution load ratio of pollution source on the sea was 12.3%, exceeded that of industrial sewage. Therefore, the pollution source at the sea was a key way not to be ignored for environmental quality in the sea area of Xiamen.
