En nylig artikel i Metroexpress (d. 6. januar) opsummerer nogle tankev\u00e6kkende resultater fra et netop udgivet videnskabeligt studie omkring effekten af trafikos1<\/sup>. Forskerne fra studiet unders\u00f8gte forekomsten af tre neurologiske sygdomme i en befolkningsgruppe i Ontario, Canada i relation til hvor t\u00e6t de boede p\u00e5 veje med tung trafik2<\/sup>.<\/p>\n

Mens forskerne ikke kunne se en markant effekt p\u00e5 forekomsten af Parkinsons syge og multipel sclerose, var der en beskeden, men signifikant forh\u00f8jet risiko for at udvikle demens. If\u00f8lge studiets data kunne 7-11% af de opst\u00e5ede demenstilf\u00e6lde tilskrives, at personen boede <50 meter fra en trafiktung vej. F\u00f8rst efter en afstand p\u00e5 >200 m, var risikoen omkring basisniveau.<\/p>\n

Selvom andre relaterede p\u00e5virkninger, s\u00e5som trafikst\u00f8j, ikke kan udelukkes som bidragende \u00e5rsag, er den hovedmist\u00e6nkte forskellige indholdsstoffer i udst\u00f8dningsgasser. Andre studier peger i samme retning. Et stort studie i Taiwan har korreleret uds\u00e6ttelse for luftforurening (ozon og partikelforurening) til udvikling af Alzheimers sygdom3<\/sup>. Et dansk studie peger desuden p\u00e5 en sammenh\u00e6ng mellem storbyrelateret luftforurening og Parkinsons sygdom p\u00e5 vore hjemlige breddegrader4<\/sup>.<\/p>\n

Disse og yderligere videnskabelige data peger alts\u00e5 p\u00e5, at l\u00e6ngerevarende eksponering for luftforurening kan bidrage til udviklingen af neurologiske sygdomme, for ikke at n\u00e6vne andre konsekvenser for helbredet \u2013 inklusive udvikling af hjertekarsygdomme, kr\u00e6ft og astmaanfald5<\/sup>.<\/p>\n

Selvom \u00f8gningen i risiko er beskeden vil jeg som pendler, som frekventerer K\u00f8benhavn de fleste af ugens dage, n\u00e6re et \u00f8nske om at der bliver indf\u00f8rt tiltag, der s\u00e6nker niveauet af luftforurenende trafik. Jeg vil dog slutteligt n\u00e6vne, at hvis man har pr\u00f8vet at bes\u00f8ge Beijing i Kina s\u00e6tter det dog ens bekymringer om byos lidt i perspektiv.<\/p>\n
