Changes in the annual over-all chromium emissions result from revisions in NFR 1 (all years) and NFR 2 (1990-2007) with the strongest relative changes occuring in NFR 2 until 2007.

Changes in the National Total reported for 1990 (+9.69 t | +7.33 %) result from a revision within NFR sub-categories 1.A.4.b i (+3.01 t | +2,356 %) and 2.C.1 (+5.6 t | +15.1 %) together wit newly implemented emission estimates for NFR sub-categories 1.A.4.a i and 1.A.4.c i.
