The analysis of biochemical components of the marine yellow substance in the Jiaozhou Bay

After the treatment and analysis of in-situ water samples taken from the Jiaozhou Bay on 1~2,September 1999 in the laboratory,the horizontal distributions and data of 6 kinds of biochemical components in marine yellow substance solution are obtained,among which the total fats measured in the treated solution of yellow substance are 21.03 mg/dm³,exactly,86.90% of the all-up amount of the biochemical components in yellow substance;the amino acids are 1.75 mg/dm³,accounting for 7.22%;and the total sugars 1.41 mg/dm³,5.82%;the amino sugars 14.23 g/dm³,0.06%;and the contents of carotenes and phenols are 1.13 and 0.004 g/dm³,respectively,while the total amounts of yellow substance make up about 24.20 mg/dm³ of the total water amounts.Comparatively speaking,the contents of the amino sugars,carotenes and phenols in the solution are very low,which are several orders of magnitude less than those of total fats,amino acids and total sugars,respectively.It is concluded that the yellow substance in the Jiaozhou Bay mainly derives from the land,its component distributions are affected by the rivers to the bay and the current in the bay,then further diffused and carried away.
