New Critical Load Function tool for acidity on APIS

critical load function toolCritical loads are used by the environment agencies, conservation agencies and others as benchmarks against which to assess the potential impacts of atmospheric deposition.  Deposition of sulphur and nitrogen compounds can contribute towards acidification and both should be taken into account when assessing potential acidification impacts.

We have now published a new tool on APIS to calculate exceedance of the acidity critical load function and for comparing nitrogen and/or sulphur deposition from a source to the critical load function.  The method has been agreed by the environment agencies and conservation agencies.
