The data and annotations have been painstakingly assembled over a 10-year period in a collaboration between academia and regulatory authorities. The work explains in detail the methods, including computational ones, for the environmental assessment of volatile and semi-volatile substances, and is rounded off with data tables of degradation rates.A key resource for manufacturers and regulators of such substances. 606 $aOrganic compounds$xBiodegradation 606 $aChemistry, Organic 615 0$aOrganic compounds$xBiodegradation. 615 0$aChemistry, Organic. 676 $a628.52 700 $aKlo?pffer$b Walter$f1938-$0626564 701 $aWagner$b Burkhard O$01730933 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910841875403321 996 $aAtmospheric degradation of organic substances$94142829 997 $aUNINA
