空气样品中氟的测定是重要的，因为它从自然和人工来源扩散到空气中。在沉积到地球表面之前，它可以通过风传播很长的距离。其在各种基质中的浓度受到法规的限制和控制，因为会造成与环境暴露相关的健康风险。采用高分辨连续光源原子吸收光谱法测定大气PM2.5中的氟。为了这些目的，在石英过滤器上收集的PM2.5空气中的颗粒物，使用大容量采样器（500 L/min）在伊斯坦布尔（土耳其）96小时在1月至6月在2年。然后，仪器和实验参数进行了优化，为分析在空气中的样品。使用标准参比物质检测分析物方法的有效性，并在95%置信水平的限度内发现认证值。对氟浓度与气象条件进行了统计比较。
Fluorine determination in airborne samples is important due to its spread into the air from both natural and artificial sources. It can travel by wind over large distances before depositing on the Earth’s surface. Its concentration in various matrices are limited and controlled by the regulations for causing health risks associated with environmental exposures. In this work, fluorine was determined in PM2.5 airborne samples by high-resolution continuum source electrothermal atomic absorption spectrometry. For these purpose, the PM2.5 airborne particulates were collected on quartz filters using high-volume samplers (500 L/min) in Istanbul (Turkey) for 96 h during January to June in 2 years. Then, instrumental and experimental parameters were optimized for the analyte in airborne samples. The validity of the method for the analyte was tested using standard reference material, and certified values were found in the limits of 95 % confidence level. The fluorine concentrations and meteorological conditions were compared statistically.
