In this study, the state of the five stations' quality was assessed on the basis of determination of temporal and spatial variability of nutrients with physicochemical variables. Besides this, organic matter of sediment, secchi disc depth and suspended solids were also determined. The samples were collected seasonally from different areas such as harbor and important touristic marinas along the eastern Aegean during June 2008-2009. As a result, the nutrients ranged between NH₄: 0.10-25.6, NO₂: 0.01-1.5, NO₃: 0.19-7.0, o.PO₄: 0.17-6.8, TPO₄: 0.32-9.6 and Si: 0.30-13.8 μM, respectively. Precipitation leads to large changes in temperature, salinity, dissolved oxygen and nutrients. The highest nutrient values in this study were observed during the rainy season except o.PO₄-P and TPO₄-P. However, the physico-chemical variables have exhibited considerable temporal variations while nutrients showed spatial differences. The relatively high nutrient increase in the sampling stations coupled with surface runoff events during rainy period and pollution arising from both point and non-point sources.
在这项研究中，基于营养物质与理化变量的时空变异性来评估五个站位的质量状况。此外，还测定了沉积物中的有机质、透明度盘深度和悬浮固体。这些样本是在 2008 年 6 月至 2009 年 6 月期间从希腊东部不同地区（如港口和重要的旅游码头区）采集的，这些地区的样本采集具有季节性。结果表明，该地区的营养物质浓度范围如下：NH₄：0.10-25.6μM、NO₂：0.01-1.5μM、NO₃：0.19-7.0μM、o.PO₄：0.17-6.8μM、TPO₄：0.32-9.6μM 和 Si：0.30-13.8μM。降水导致温度、盐度、溶解氧和营养物质发生较大变化。本研究中，除 o.PO₄-P 和 TPO₄-P 外，最高的营养值出现在雨季。然而，理化变量表现出相当大的时间变化，而营养物质则表现出空间差异。在降雨期间，由于地表径流事件和点源及非点源污染，采样站的相对高营养物增加。
