Understanding and addressing the environmental risk of microplastics
《环境科学与工程前沿(英文)》 2023年 第17卷 第1期 doi: 10.1007/s11783-023-1612-5
Over the past decades, the plastic production has been dramatically increased. Indeed, a category of small plastic particles mainly with the shapes of fragments, fibers, or spheres, called microplastics (particles smaller than 5 mm) and nanoplastics (particles smaller than 1 μm) have attracted particular attention. Because of its wide distribution in the environment and potential adverse effects to animal and human, microplastic pollution has been reported as a serious environment problem receiving increased attention in recent years. As one of the commonly detected emerging contaminants in the environment, recent evidence indicates that the concentration of microplastics show an increasing trend, for the reason that up to 12.7 million metric tons of plastic litter is released into aquatic environment from land-based sources each year. Furthermore, microplastic exposure levels of model organisms in laboratory studies are usually several orders of magnitude higher than those found in environment, and the microplastics exposure conditions are also different with those observed in the environment. Additionally, the detection of microplastics in feces indicates that they can be excreted out of the bodies of animal and human. Hence, great uncertainties might exist in microplastics exposure and health risk assessment based on current studies, which might be exaggerated. Policies reduce microplastic emission sources and hence minimize their environmental risks are determined. To promote the above policies, we must first overcome the technical obstacles of detecting microplastics in various samples.

针对水电工程风险因子的时变特性,用随机过程的方法模拟结构抗力与荷载作用,分析水电工程结构特性与运行方式,综合运用改进层次分析法、时变可靠度理论和风险率阈值,建立水电工程运行安全风险率评估模型。以土石坝工程为算例,详细展示时变风险率评估方法的分析流程。算例表明,工程运行安全风险率与服役时间及设计标准有着密切关系;考虑时变效应,风险率随时间推移而逐渐增大,其与设计标准的交点反映结构技术性使用寿命。应用文章提出的评估模型,预测运行期风险率变化趋势,可为水电工程的安全运行和风险决策提供科学依据。

文章引人随机微分方程,采用泄洪风险分析方法评估水电站采用非常泄洪设施对大坝安全所带来的影响,并结合某一工程设置两条非常泄洪洞的可行性进行论证。在充分分析计算条件对风险率灵敏性的前提下,讨论了调洪方案下两条非常泄洪洞启用的条件及相关的泄洪风险,为导流洞改建方案的确定提供依据。分析结果表明该方案基本维持原设计方案的泄洪风险水平,说明设置非常泄洪设施是可行的。
