The fire at Notre-Dame cathedral, Paris, in April 2019, was an acute pollution event, releasing lead (Pb)-rich dust into the city. To assess Pb distribution, honey samples (n = 36) were collected (in July 2019) from hives throughout the Île-de-France following the fire and were analyzed for a suite of metal concentrations and Pb isotopic compositions. Honey from hives downwind of the fire has elevated Pb concentrations (0.023 μg/g Pb, geometric mean) compared to other honey from central Paris (0.008 μg/g), prefire Paris (0.009 μg/g), and the Rhône-Alpes region (0.004 μg/g). The Pb isotopic range for all analyzed honey (Paris and Rhône-Alpes, 1.144–1.179 ²⁰⁶Pb/²⁰⁷Pb, 2.079–2.125 ²⁰⁸Pb/²⁰⁶Pb) falls within the modern Pb isotopic range for French aerosols and sediments, signifying that the fire did not perturb the isotopic composition of Parisian honey. The variations in downwind Pb concentrations demonstrate the utility of honey as a biomonitor after an acute pollution event. The isotope results are supported by the construction history of Notre-Dame cathedral and historical record of Pb ores used throughout France.

蜂蜜绘制了巴黎圣母院大教堂2019年大火中的铅污染图：地球化学视角

2019年4月，巴黎圣母院大教堂发生的大火是一次严重的污染事件，向城市释放了富含铅（Pb）的灰尘。为了评估Pb的分布，火灾发生后（2019年7月）从整个法兰西岛的蜂巢中收集了蜂蜜样品（n = 36），并对其中的金属浓度和Pb同位素组成进行了分析。与来自巴黎中部（0.008μg/ g），预火巴黎（0.009μg/ g）和罗纳-阿尔卑斯大区的其他蜂蜜相比，烈风顺风的蜂蜜的Pb浓度（0.023μg/ g Pb，几何平均值）升高。 （0.004μg/ g）。所有分析蜂蜜的铅同位素范围（巴黎和罗纳-阿尔卑斯，1.144–1.179 ²⁰⁶ Pb / ²⁰⁷ Pb，2.079–2.125 ²⁰⁸ Pb / ²⁰⁶Pb）落在法国气溶胶和沉积物的现代Pb同位素范围内，表明大火并未扰乱巴黎蜂蜜的同位素组成。顺风铅浓度的变化证明了急性污染事件后蜂蜜作为生物监测器的效用。巴黎圣母院大教堂的建设历史和整个法国使用的铅矿石的历史记录证明了同位素的结果。
