Abstract：
Urbanization and technological advancements result in the dispersion of antropogenic electromagnetic fields (EMF) that can affect on ecosystems. Therefore, it is important to understand their impact on the environment. Aquatic ecosystems are subject to EMF as part of various electricity sources, e.g., high-voltage transmission lines (HVTL). We examined the impact of EMF generated by HVTL on the spatial arrangement and survival of pike (Esox lucius) embryos. Fertilized eggs were incubated under two HVTL configurations 110 kV and 220 kV compared with a control group devoid of anthropogenic EMF. Embryo orientation and survival were monitored until blastopore closure. The control group showed dominance in the arrangement of embryos along the N-S, NNW-SSE, and NNE-SSW axes, with a slight prevalence of northern directions. EMF originating from HVTL did not exert a significant influence on the spatial arrangement of pike embryos, although some deviations from the arrangement noticed in the control group were observed. Increased embryo mortality was observed only at 110 kV site, but probably due to factors unrelated to EMF. In conclusion, EMF generated by HVTL did not significantly change pike embryo orientation or chances of survival. However, longer exposure or higher EMF levels could provoke notable reactions, requiring ongoing evaluation as power networks continue to spread more widely.
摘要：
城市化和技术进步导致可能影响生态系统的内生电磁场（EMF）的分散。因此,了解它们对环境的影响很重要。水生生态系统作为各种电力来源的一部分受到EMF的影响，例如，高压输电线路（HVTL）。我们研究了HVTL产生的EMF对梭鱼（Esoxlucius）胚胎的空间排列和存活的影响。与没有人为EMF的对照组相比，受精卵在110kV和220kV的两种HVTL配置下孵育。监测胚胎取向和存活直至胚孔闭合。对照组在沿N-S排列的胚胎中显示出优势，NNW-SSE,和NNE-SSW轴，向北方向有轻微的流行。源自HVTL的EMF对梭鱼胚胎的空间排列没有显着影响，尽管观察到与对照组的安排有一些偏差。仅在110kV部位观察到胚胎死亡率增加，但可能是由于与EMF无关的因素。总之,HVTL产生的EMF不会显着改变派克胚胎的方向或存活机会。然而,长时间暴露或更高的EMF水平可能会引起明显的反应，随着电力网络继续更广泛地传播，需要进行持续的评估。
