科学领域:

环境科学环境科学
分析化学分析化学
频谱学是一种光谱学.

背景情况:

微塑料 (MP) 污染是一个日益严重的环境问题.
准确检测和量化MP对于环境监测和风险评估至关重要.
现有的MP检测分析方法,特别是使用微福里埃变换红外光谱 (μFTIR) 成像,在实验室之间有所不同.

研究的目的:

用μFTIR成像检测微塑料的两种不同的分析方法进行比较.
调查程序差异如何影响MP检测,丰度和质量估计.
确定导致MP分析结果差异的关键因素.

主要方法:

针对多河水复合样本的子样本,应用了两种不同的μFTIR成像方法.
在MP隔离程序,光学基板 (化窗与Anodisc过器) 和μFTIR仪器分辨率 (5.5μm与25μm像素大小) 中,方法有所不同.
分析了MP的丰度,质量和特征,并将这两种方法进行了比较.

主要成果:

在两种方法之间观察到MP丰度和质量估计的显著差异,特别是在颗粒>50μm.
与较低分辨率的方法 (16.7-72.1 MP m-3和222-439 μg m-3) 相比,具有更高分辨率 (5.5 μm) 的方法报告了明显更高的MP丰度 (418-2571 MP m-3) 和质量估计 (703-1900 μg m-3).
基板类型 (Anodisc过器与ZnSe窗口) 和μFTIR分辨率由于粒子聚合和"IR-halo"效应显著影响了结果,而MP隔离程序的影响很小.

结论:

μFTIR仪器分辨率和光学基板的选择是影响微塑料检测精度和量化的关键因素.
样本之间的变异性可以超过方法诱导的差异,突出需要强大的采样策略.
分析方法的协调,包括μFTIR设置和基质选择,对于减少实验室间的变异性和提高微塑料研究的可靠性至关重要.
