方法在这项研究中，试图调查湖水和水之间发生的一些磷酸盐交换过程。由于从乌尔卡河口到开放湖的正磷酸盐浓度存在明显的梯度，从入海口到开放湖的横断面固定了三个采样站：一个位于入水口附近，靠近芦苇带，另外两个位于开放湖内，相距1公里。因此，第三个站的磷酸盐浓度应代表湖泊平均值。在模拟湖泊条件的实验装置中进行了磷酸盐吸收实验。通过连续搅拌防止实验烧瓶（2000ml）中的塞斯顿的沉淀和絮凝。样品通过 50 pm 网筛过滤以除去较大的浮游动物。在所有实验中，使用 Tris 缓冲液将样品保持在 20°C 和 pH 8.7（湖的平均值）。分别使用标准原子吸收光谱和 X 射线衍射程序测定了该材料的化学和矿物学成分。吸收实验后，吸收的磷酸盐通过连续的ex-分级分离
MethodsIn this study, an attempt was made to investigate some of the phosphate exchange processes which are taking place between the lake water and the seston. As there is a sharp gradation in orthophosphate concentrations from the Wulka mouth to the open lake, three sampling stations were fixed along a transect from the inlet to the open lake: one situated near the inflow, dose to the reed belt, and the other two located in the open lake, l km apart. The third station should thus have a phosphate concentration representative of the lake average.Phosphate uptake experiments were carried out in an experimental set up, that simulated lake conditions. Sedimentation and flocculation of the seston in experimental flasks (2000 ml) were prevented by continuous stirring. Samples were filtered through 50 pm mesh sieve to remove larger zooplankton. In all experiments, samples were maintained at 20 C and at a pH 8.7 (mean value for the lake) using a Tris buffer. The chemical and mineralogical composition of the sestonic material were determined using standard atomic absorption spectroscopic and X-ray diffraction procedures, respectively. Mter the uptake experiments, the absorbed phosphate was fractionated by serial ex-
