- 纳米材料的安全性
- 水生生态毒理学 水生生态毒理学
背景情况:
- 纳米技术的进步导致纳米粒子 (NP) 的使用增加.
- 纳米材料对水生生物的潜在有害影响需要彻底调查.
- 氧化铜纳米颗粒 (CuO-NPs) 被广泛使用,需要进行毒性评估.
研究的目的:
- 为了评估铜氧化物纳米粒子 (CuO-NPs) 在金鱼 (Carassius auratus) 中的致命毒性值.
- 检查CuO-NPs对金鱼血液参数,和肝脏组织的亚致命毒性影响.
主要方法:
- 金鱼在96小时内暴露于不同度的CuO-NP (10-100 mg/L).
- 试管体分析确定了LC50 (50%的鱼类的致命度).
- 使用次致死度 (5%,10%,15%LC50) 来评估和肝脏对血液学和组织病理学的影响.
主要成果:
- 对于鱼类死亡率,观察到度与反应的关系.
- 亚致死的CuO-NP暴露降低了白细胞数量和葡萄糖水平,同时增加了蛋白质和甘油三水平.
- 组织病理学检查显示了 (过度增生,叶片损伤) 和肝脏 (亡,细胞胀) 的显著组织损伤.
结论:
- 在金鱼中,CuO-NP具有剂量依赖的毒性.
- 暴露于CuO-NPs会导致显著的血液学变化和对重要器官的严重组织病理损伤.
- 该研究强调了水生生态系统中CuO-NP污染相关的环境风险.

OverviewElements are the smallest units of matter that cannot be broken down further by chemical processes. There are 118 known elements, but not all of these are naturally-occurring, and fewer still are essential for life. Living matter is composed primarily of carbon, nitrogen, hydrogen, and oxygen, with smaller amounts of other elements like calcium, phosphorus, potassium, and sulfur. Other elements are also necessary for life but only in trace amounts.The Periodic Table Provides Information...

118
Microbial leaching, also known as bioleaching, is an environmentally favorable method for extracting metals from low-grade ores using specific microorganisms. This biotechnological approach is particularly valuable for mining operations targeting copper, gold, and uranium, where traditional extraction methods may be economically or environmentally impractical.Copper Leaching and Microbial CatalysisIn copper bioleaching, crushed ore is arranged into heaps and irrigated with a dilute sulfuric...
