概括

金属氧化物纳米粒子 (NP) 对两动物有毒,在高温下毒性增加. 全球变暖可能会加剧NP对两动物种群的影响,需要进行保护工作.

科学领域:

环境毒理学环境毒理学
纳米毒理学研究
两动物生态两动物生态

背景情况:

金属氧化物纳米粒子 (NP) 对两动物的环境影响基本上是未知的.
高温可能会改变NP的毒性,对两动物群体构成风险.

研究的目的:

研究六种金属氧化物NP (Al2O3,CuO,Fe3O4,NiO,ZnO,TiO2) 对Bufotes viridis胚胎和幼虫的毒性.
评估NP毒性与环境 (AT) 和高 (HT) 温度对两动物生存,发育,行为和组织学的相互作用.

主要方法:

暴露Bufotes viridis胚胎和幼虫的致命度 (LC25%,LC50%,LC75%) 的各种金属氧化物NP的10天.
在环境 (18°C) 和高 (21°C) 温度下进行测试.
评估生存率,化成功,发育异常,行为变化和组织学变化.

主要成果:

氧化 (NiO) 和氧化 (ZnO) 的NP在两种温度下都表现出最高的毒性,在高温下死亡率和发育问题增加.
一般来说,NP降低了化率和生存率,增加了异常,并减缓了发展,特别是在高温下.
行为变化包括在环境温度下低活性和在高温下高活性,有肝脏和状组织损伤的组织学证据.

结论:

全球变暖可能会加剧金属氧化物NP对两动物的毒性.
进一步的研究和保护策略至关重要,以减轻气候变化中对两动物种群的NP风险.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Responses to Heat and Cold Stress

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Threats to Biodiversity

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
