Cette \u00e9tude examine la pr\u00e9sence de microplastiques dans les eaux souterraines de l’archipel arctique canadien \u00e0 l’aide d’\u00e9chantillons pr\u00e9lev\u00e9s en 2018 \u00e0 bord du NGCC Amundsen. Les r\u00e9sultats montrent des concentrations faibles mais d\u00e9tectables de microplastiques (0,031 particule par litre), principalement des microfibres textiles telles que le polyester et l’acrylique. Des microplastiques ont \u00e9t\u00e9 trouv\u00e9s dans la plupart des sites d’\u00e9chantillonnage, les concentrations les plus \u00e9lev\u00e9es \u00e9tant observ\u00e9es dans la baie de Baffin, bien qu’aucun lien significatif n’ait \u00e9t\u00e9 \u00e9tabli avec des facteurs environnementaux. L’\u00e9tude sugg\u00e8re que le transport maritime pourrait \u00eatre une source locale de microfibres, en particulier par le rejet d’eaux grises, et souligne l’importance d’une surveillance continue \u00e0 l’aide de navires comme plateformes d’\u00e9chantillonnage.<\/p>\n <\/div>\r\n\r\n \r\n \r\n \r\n \r\n \r\n \"\"\r\n <\/a>\r\n \r\n \r\n \r\n \r\n
