The Associations of Prenatal Exposure to Fine Particulate Matter and Its Chemical Components with Allergic Rhinitis in Children and the Modification Effect of Polyunsaturated Fatty Acids: A Birth Cohort Study

Abstract

Prenatal exposure to <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mrow><mml:msub><mml:mrow><mml:mrow><mml:mi>PM</mml:mi></mml:mrow></mml:mrow><mml:mrow><mml:mrow><mml:mn>2.5</mml:mn></mml:mrow></mml:mrow></mml:msub></mml:mrow></mml:mrow></mml:math> and its chemical components, particularly BC, was associated with AR/symptoms in early childhood. We highlight that PUFA biomarkers could modify the adverse effects of <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mrow><mml:msub><mml:mrow><mml:mrow><mml:mi>PM</mml:mi></mml:mrow></mml:mrow><mml:mrow><mml:mrow><mml:mn>2.5</mml:mn></mml:mrow></mml:mrow></mml:msub></mml:mrow></mml:mrow></mml:math> on respiratory allergy. https://doi.org/10.1289/EHP13524.
