概括

用于增加北极海冰白度的空洞玻璃微球 (HGM) 可以被海洋生物摄入. 虽然没有急性毒性,但长时间暴露会对足动物的生存和能量产生负面影响,这表明潜在的生态系统风险.

科学领域:

环境科学环境科学
海洋生物学海洋生物学
生态毒理学生态毒理学

背景情况:

建议使用空洞玻璃微球 (HGM) 来增强北极海冰的白色变化.
评估HGMs对环境的影响对于安全应用至关重要.
降解后的HGM可能会沉没并与海洋生物相互作用.

研究的目的:

研究HGM与北极足动物 (Calanus finmarchicus) 和北极鱼 (Gadus morhua) 的相互作用.
评估HGM暴露对这些物种的急性和慢性毒性.

主要方法:

实验室实验使足动物和鱼幼虫暴露在各种HGM度中.
对HGM摄入,粘附,死亡率和发育影响的观察.
在copepods中分析脂质积累和生存率.

主要成果:

在鱼幼虫,copepodites和成年copepods中发生了HGM摄入.
没有观察到急性死亡或粘附.
长时间暴露于HGM (17天) 减少了copepod脂质的积累和生存时间.
除了在非常高的度 (1000 mg/L) 之外,脉发育没有受到影响.

结论:

空洞的玻璃微球不会对copepods或鱼幼虫造成急性毒性.
持续的HGM过会影响类动物的能量,生存和脂质积累.
需要进一步的研究来评估HGM对鱼幼虫生长和发育的影响.

Deep Sea Microbial Ecology

Deep Sea Microbial Ecology

The deep ocean and its underlying sediments represent vast, largely unexplored microbial habitats that extend far beyond the sunlit photic zone. The photic (euphotic) zone typically spans the upper ~100–200 meters of pelagic waters in the open ocean, but its depth varies geographically and seasonally, where sufficient light supports photosynthetic life. Below this lies the deep sea, spanning roughly 1000–6000 meters (bathypelagic to abyssal zones), with deeper hadal trenches extending beyond...
