Influence of Source Input on Spatial-temporal Variations of PHC in Jiaozhou Bay
This paper analyzed the influence of source input on spatial-temporal variations of Petroleum hydrocarbon(PHC)in Jiaozhou Bay using investigation data on PHC in May and August 1990.Results showed that the contents of PHC in May,and August 1990 in surface waters in Jiaozhou Bay were 0.018-0.270 mg L-1 and 0.020-0.081 mg L-1,respectively.In May 1990,PHC contents in estuary of Dagu River were confirm to Class III(moderate polluted),compared to Class Ⅰ(include Ⅱ)in other regions(slight polluted).In August 1990,PHC contents in estuary of Haibo River were confirm to Class Ⅲ(moderate polluted),compared to Class I(include II)in other regions(slight polluted).Dagu River and Haibo River were the major PHC sources in May 1990,while Haibo River was the major PHC source in August 1990.For a same source(i.e.,Haibo River),the source strength in May was three-fold to what in August.For a same investigation time(i.e.,May),the source strength of PHC in Dagu River was ahead of what in Haibo River.The spatial-temporal variations of the source input from river discharge were influencing the spatial-temporal changes of PHC contents in Jiaozhou Bay.
