【Abstract】 In November 1998, the data of trace metals, nutrients, DO, salinity etc. were observed continuously at the net cage culture area for 24h in Dapeng′ao(bight) at Daya Bay. The mass balance experiment shows that it is feasible to recover trace metals by cross flow ultrafiltration experiment. The features of diurnal variation in both trace metals in different size fractions and the seawater environmental parameters are analyzed. The relationship between dissolved trace metals and nutriants in the net cage culture area is discussed.更多还原
