Overskridelser av tålegrenser for forsuring og nitrogen for Norge – oppdatering med perioden 2007–2011

Abstract

Rapporten viser overskridelser av tålegrenser for forsuring av vann og jord, samt overgjødslingseffekter på vegetasjon, med avsetningsverdier for perioden 2007–2011. Disse avsetningsverdiene gir noe reduksjon i areal med overskridelse av tålegrenser for vann siden forrige periode: Ved bruk av den mest vanlige modellen og inkludering av organiske syrer (SSWCoaa) er 8 % av Norges areal er overskredet (10 % i forrige periode). Bruk av FABoaa-modellen, som forutsetter full nitrogenmetning og dermed et mye større forsuringsbidrag fra nitrogen, gir en overskridelse på 19 % av Norges areal. Dette er også en liten reduksjon siden forrige periode (21 %). Overskredet areal for overgjødslingseffekter på vegetasjon fra nitrogen viser det samme som de tre foregående periodene: 21 % av Norges areal er overskredet.
