\n“\u00cen ultimii 10 ani, am \u00eenceput s\u0103 observ\u0103m asocieri statistice \u00eentre poluarea aerului \u015fi o \u00eentreag\u0103 gam\u0103 de probleme legate de creier – de la modul \u00een care copiii \u00eenva\u0163\u0103, la modul \u00een care se schimb\u0103 facult\u0103\u0163ile lor cognitive, la probleme de s\u0103n\u0103tate mintal\u0103 \u015fi risc crescut de demen\u0163\u0103”, explic\u0103 Ian Mudway, toxicolog de mediu la Imperial College London \u015fi unul dintre cercet\u0103torii principali ai studiului.<\/p>\n
\nEchipa recreeaz\u0103 \u00een laborator patru tipuri diferite de poluare: emisiile de gaze de e\u015fapament ale unui motor diesel, fumul de la arderea lemnului, mirosul produselor de cur\u0103\u0163are \u015fi vaporii de la g\u0103titul c\u0103rnii.<\/p>\n
\nNivelurile fiec\u0103rui poluant sunt analizate \u015fi m\u0103surate cu aten\u0163ie \u00eenainte ca aerul nes\u0103n\u0103tos s\u0103 fie direc\u0163ionat spre voluntari. Voluntarii sunt supu\u015fi la expuneri de o or\u0103 la fiecare tip de poluare, timp de mai multe luni. \u00cenainte \u015fi dup\u0103 fiecare expunere, li se fac teste cognitive \u015fi se recolteaz\u0103 probe biologice.<\/p>\n
\nScopul este de a clarifica modul \u00een care diferi\u0163ii poluan\u0163i respira\u0163i d\u0103uneaz\u0103 creierului \u015fi de a-i pune \u00een a\u015feza \u00een ordinea periculozit\u0103\u0163ii. Scopul este \u015fi acela de a stabili dac\u0103 poluan\u0163ii ajung direct la creier sau dac\u0103 daunele care reies din studii sunt un efect indirect, de exemplu din cauza inflama\u0163iei \u00een curs de desf\u0103\u015furare \u00een alte p\u0103r\u0163i ale corpului, cum ar fi pl\u0103m\u00e2nii.<\/p>\n
\nO mai bun\u0103 \u00een\u0163elegere a impactului aerului poluat asupra creierului este de mare importan\u0163\u0103, nu numai pentru a \u00eencerca s\u0103 contracareze cele \u015fapte milioane de decese premature cauzate \u00een fiecare an de poluarea exterioar\u0103 \u015fi interioar\u0103, ci \u015fi pentru a \u00een\u0163elege \u015fi a preveni originea unora dintre cele mai r\u0103sp\u00e2ndite tulbur\u0103ri cerebrale, de la demen\u0163\u0103 la depresie.<\/p>\n
