The lead story of the fire at the Notre-Dame cathedral of Paris

On 15th April 2019, Parisians watched in shock as Notre-Dame de Paris, the iconic cathedral that has towered over their city for almost 900 years, was engulfed in flames. Although flames destroyed the spire and considerably weakened the structure, no human lives were lost. However, as some amounts of lead volatilized and deposited in the surrounding areas, fears of potential intoxication began to rise. We investigated the impact of this fire on the blood lead levels of adults in Paris according to the distance between the cathedral and where they live or work. The geometric mean of blood lead levels of the study population was 1.49μg/dl (95% CI [1.38–1.62]) with a prevalence of blood lead levels≥5.0μg/dL of 5.0%. Despite the early legitimate fears of intoxication, the fire that destroyed a significant part of the Notre-Dame cathedral did not increase the blood lead levels of adults living and working in the vicinity.
