于1989年10月28日在胶州湾的23个站位采集表层水样,对Ca、Mg及盐度、氯度、碱度等化学要素进行了测定,并用崂山水库水进行了稀释实验。结果表明,Ca/s,Mg/s均高于大洋水,其值分别为0.01250±7×10~(-4)和0.03728±1×10~(-4)。湾东北部的Ca,Mg均高于中部及湾口海域,这是湾东北部的工业废水及高盐卤水排放所致;CaCO_3(20℃)呈现过饱和状态。认为,ca,Mg有良好的保守性,低盐混合水样在放置过程中pH的下降可能与空气中CO_2的溶解有关,从而将引起ca,Mg含量的相对增高。
On October 28, 1989, surface water samples were collected from 23 stations in Jiaozhou Bay. The chemical elements Ca, Mg, salinity, chlorinity and alkalinity were measured and diluted with Laoshan reservoir water. The results showed that Ca / s and Mg / s were higher than that of ocean water, and their values were 0.01250 ± 7 × 10 -4 and 0.03728 ± 1 × 10 -4, respectively. The contents of Ca and Mg in the northeast of the Bay are higher than those in the central and bayou areas. This is caused by the industrial wastewater and high-salt brine discharged from the northeast of the Bay. The CaCO 3 (20 ℃) shows supersaturation. It is considered that ca and Mg are well conserved. The decrease of pH in the low salt mixed water sample may be related to the dissolution of CO 2 in the air, which will cause the relative increase of ca and Mg contents.
