概括

暴露于六价显著影响鱼,增加死亡率并改变关键的血液和血成分. 半致命度被确定为58.84毫克Cr6+/L.

科学领域:

环境毒理学环境毒理学
水生物质毒理学研究
鱼类生理学鱼类生理学

背景情况:

六价 (Cr6+) 是一种有毒的重金属污染物.
水生生物对水中传播的污染物很脆弱.
了解Cr6+对鱼类的影响对于环境风险评估至关重要.

研究的目的:

为了确定六价对星鱼 (Platichthys stellatus) 的急性毒性.
为了研究星鱼对Cr6+暴露的血液和血生化反应.

主要方法:

在96个小时内,饥饿的鱼被暴露在不同度的六价 (080毫克/升) 中.
监测生存率以确定半致命度 (LC50).
血液学参数 (红血细胞,血红蛋白,血红素) 和血成分 (,葡萄糖,胆固醇,AST,ALT,ALP) 被分析.

主要成果:

暴露于六价的星状鱼的96小时LC50为58.84毫克Cr6+/L.
观察到红细胞计数,血红蛋白和血红素的显著增加.
血中的,葡萄糖,胆固醇,AST,ALT和ALP水平在Cr6+暴露时显著增加.

结论:

对水中六价的急性暴露显著降低了星星的生存率.
六价暴露会导致血液学参数和血生物化学的显著变化.
这些发现突显了Cr6+在P. stellatus中的生理压力和毒性.

The Periodic Table and Organismal Elements

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...
