遗留采矿设施对水生资源构成重大风险。 2021 年 3 月 30 日至 4 月 9 日，Piney Point 设施的 8.14 亿升磷酸盐开采废水和海洋疏浚水被排放到坦帕湾下游（美国佛罗里达州）。这导致总氮量预计增加 186 吨，超过了典型的年度外部氮负荷估计值，导致坦帕湾在几天内下降。四月份首次观察到浮游植物大量繁殖（无害硅藻）。丝状蓝藻水华 (Dapisspp.) 在 6 月达到顶峰，随后是赤潮生物短卡氏藻 (Karenia brevis) 的水华。追踪报告的鱼类死亡情况 K.短浓度，促使清理了超过 1600 吨死鱼。在研究期间海草的变化很小。通过将这些结果与基线环境监测数据进行比较，我们证明了异常高且快速输送的氮负荷导致的不良水质变化。
Legacy mining facilities pose significant risks to aquatic resources. From March 30th to April 9th, 2021, 814 million liters of phosphate mining wastewater and marine dredge water from the Piney Point facility were released into lower Tampa Bay (Florida, USA). This resulted in an estimated addition of 186 metric tons of total nitrogen, exceeding typical annual external nitrogen load estimates to lower Tampa Bay in a matter of days. An initial phytoplankton bloom (non-harmful diatoms) was first observed in April. Filamentous cyanobacteria blooms (Dapisspp.) peaked in June, followed by a bloom of the red tide organismKarenia brevis. Reported fish kills trackedK. brevisconcentrations, prompting cleanup of over 1600 metric tons of dead fish. Seagrasses had minimal changes over the study period. By comparing these results to baseline environmental monitoring data, we demonstrate adverse water quality changes in response to abnormally high and rapidly delivered nitrogen loads.
