Twenty-five sampling stations were selected in order to monitor persistent organic pollutants (polycyclic aromatic hydrocarbons (PAHs), organochlorine (OC) pesticides and total polychlorinated biphenyls (PCBs)) in surface water from Kerkini Lake, the Strymon River, its main tributaries and estuary in N. Aegean Sea during January to July, 2008, according to recent European Union (EU) guidelines. The data were divided among the high (January to April) and the low flow season (May to July). Generally, the values for organic pollutants were within the range reported worldwide for surface water. Elevated PAHs concentrations were observed compared with other places in Greece. Anthracene and benzo(a)pyrene exceeded maximum allowable concentration (MAC) of the relative EU guideline. Also, concentrations above MAC were observed for OCs, γ-HCH, and a-endosulfan. Despite the fact that it is banned since 1972, Aldrin was detected during the monitoring season (from limit of detection (LOD) to 15 ng L(-1)). Total PCB concentrations ranged from LOD to 162 ng L(-1). In addition, the load of organic pollutants was estimated in April (high flow) and June (low flow) in selected sampling stations. According to this estimation, napthalene, anthracene, and fluoranthene (PAHs), total dichlorodiphenyltrichloroethane (DDT), aldrin, and total PCBs had the highest load. Taking into account the relative EU guidelines concerning the pollutants studied, the water quality in the Strymon River catchment could be characterized as poor, which can lead to negative impacts to its biota.
根据最近的欧盟 (EU) 指南，为了监测克里基纳湖、斯特里蒙河及其在北爱琴海的主要支流和河口的地表水持久性有机污染物 (多环芳烃 (PAHs)、有机氯 (OC) 农药和总多氯联苯 (PCBs))，选择了 25 个采样站。数据分为高流量期（1 月至 4 月）和低流量期（5 月至 7 月）。一般来说，有机污染物的数值在世界范围内报道的地表水范围内。与希腊其他地方相比，PAHs 浓度较高。蒽和苯并 (a) 芘超过了相对欧盟指南的最大允许浓度 (MAC)。此外，OCs、γ-六氯环己烷和α-硫丹的浓度也超过了 MAC。尽管自 1972 年以来已被禁用，但在监测季节（从检测限 (LOD) 到 15 ng L(-1)) 检测到了艾氏剂。总 PCB 浓度范围从 LOD 到 162 ng L(-1)。此外，在选定的采样站中，还估计了 4 月（高流量）和 6 月（低流量）的有机污染物负荷。根据这一估计，萘、蒽和荧蒽（PAHs）、总滴滴涕、艾氏剂和总多氯联苯的负荷最高。考虑到有关研究污染物的相对欧盟指南，斯特里蒙河流域的水质可以说是较差的，这可能会对其生物群产生负面影响。
