Abstract

Phytoplankton responds rapidly to nutrient availability variations, becoming a useful indicator for eutrophication and/or management actions to reduce it. The present study evaluated the medium-term response of the phytoplankton community of a temperate estuary (Urdaibai estuary) to the cessation of discharges from a wastewater treatment-plant (WWTP), comparing the physicochemical conditions and the phytoplankton community before (2020) and after (2022) the sewerage works. The cessation led to a decrease of ammonium and phosphate, causing decreases of phytoplankton biomass in the outer and middle estuary and increases in the surroundings of the WWTP. Community composition also changed, recording an increase of prasinoxanthin-containing algae's contribution to total biomass, and a composition shift in the inner estuary, from mainly flagellates (alloxanthin-containing and chlorophyll b-containing algae) to the increase of diatoms, which could be prompted by the change of nutrient-ratios and the nitrogen source, and might indicate the recuperation of the system.

根据高效液相色素的 PIGMENTUM 分析，乌尔代拜河口（比斯开湾东南部）浮游植物群落对停止废水排放的反应。

浮游植物对养分供应量的变化反应迅速，成为富营养化和/或减少富营养化管理行动的有用指标。本研究评估了温带河口（乌尔代拜河口）浮游植物群落对污水处理厂停止排放的中期反应，比较了污水处理工程之前（2020 年）和之后（2022 年）的物理化学条件和浮游植物群落。停止排污导致铵和磷酸盐的减少，导致河口外围和中间的浮游植物生物量减少，而污水处理厂周围的浮游植物生物量增加。群落组成也发生了变化，记录到含镨黄素的藻类在总生物量中所占比例增加，内河口的群落组成也发生了变化，从主要是鞭毛藻（含藻黄素和叶绿素 b 的藻类）到硅藻的增加，这可能是由于营养比率和氮源的变化引起的，也可能预示着系统的恢复。

期刊介绍： Marine Environmental Research publishes original research papers on chemical, physical, and biological interactions in the oceans and coastal waters. The journal serves as a forum for new information on biology, chemistry, and toxicology and syntheses that advance understanding of marine environmental processes. Submission of multidisciplinary studies is encouraged. Studies that utilize experimental approaches to clarify the roles of anthropogenic and natural causes of changes in marine ecosystems are especially welcome, as are those studies that represent new developments of a theoretical or conceptual aspect of marine science. All papers published in this journal are reviewed by qualified peers prior to acceptance and publication. Examples of topics considered to be appropriate for the journal include, but are not limited to, the following: – The extent, persistence, and consequences of change and the recovery from such change in natural marine systems – The biochemical, physiological, and ecological consequences of contaminants to marine organisms and ecosystems – The biogeochemistry of naturally occurring and anthropogenic substances – Models that describe and predict the above processes – Monitoring studies, to the extent that their results provide new information on functional processes – Methodological papers describing improved quantitative techniques for the marine sciences.
