In almost all regions, non-marine sulphate delcined significantly between 1990 and 2008 (15 to 59%). Chemical recovery was also demonstrated in positive trends in pH and alkalinity. Chemical recovery is paving the way for some biological recovery." . "Paterson, Andrew" . . . . "21"^^ . "Hogasen, Tore" . . . "51185" . "Kr\u00E1m, Pavel" . . "[86002D419798]" .
