Value calculated by interpolation between targets for 2010 and 2050<br />
² Value derived from PM10 critical flow and PM2.5 proportion<br />
³ Value calculated from ratio of current to critical flow of emissions to soil<br />
Temporal reference: The figures are based on the data available in 2006.<br />
On data accuracy: The flows are not rounded, thus allowing for optimal traceability in source texts. Scarcity and weighting factors are rounded to two digits.
