Description
Français : Pesticides dans l'air urbain de la ville de Reims (Département de la Marne, France) profil pour quelques paramètres mesurés à Reims de 2012 à 2016, de février à mi-décembre sur le site « Sacré-Coeur » de Reims, afin d’étudier l’évolution saisonnière et annuelle de la présence de certains pesticides dans l’air en milieu urbain. Cette étude a aussi montré
- une forte variation des cumuls hebdomadaires selon l'année et la saison (notamment expliquée par les variations de météo et de pression parasitaire et de la date de départ végétatif des cultures)  ;
- un recul de certaines substances actives en 2015-2016 (13 molécules retrouvées au dessus des seuils de quantification, contre 20 en 2012 - 2013)  ;
- une diminution de la part des fongicides durant l’été de 2013 à 2016 ;
- augmentation de la concentrations désherbants en automne de 2014 à 2016
- une persistance du lindane, (interdite depuis longtemps, mais retrouvé chaque année à faibles doses (moins de 1 ng/m3), source : ATMO Grand-Est / Rapport activité 2016 d'Atmo (voir p 35)
