贝利兹新河的鱼类死亡与低氧水平有关, A fish kill in Belize’s New River is tied to low oxygen levels from algal blooms likely caused by agricultural runoff.

贝利兹新河附近发现的一种鱼类死亡与危险的低溶氧水平有关, - - 下降至2.54 mg/l,低于水生生物所需的3 mg/L值. A fish kill in Belize’s New River, detected near San Estevan, is linked to dangerously low dissolved oxygen levels—down to 2.54 mg/l—below the 3 mg/l threshold needed for aquatic life. 素的增加表明藻类过度生长, 这可能会在分解时耗尽氧气. Elevated chlorophyll suggests excessive algae growth, which likely depleted oxygen as it decomposed. 环境部怀疑农业排放的原因是含有酸盐和酸素的肥料, 不过非点源使得确切原因难以追踪. The Department of Environment suspects agricultural runoff from fertilizers containing nitrates and phosphates, though non-point sources make exact causes hard to trace. 虽然干旱季节可能会使情况恶化,但自2019年以来河流逐渐恢复,鱼类死亡越来越少. While the dry season may worsen conditions, the river has shown gradual recovery since 2019 with fewer and less severe fish kills. 能源部继续监测和分析数据以防止未来的事件. The DOE continues monitoring and analyzing data to prevent future incidents.
