(e)Recovering any compound of cadmium or mercury.
(f)Unless falling within any other Section, any manufacturing activity involving the use of mercury or cadmium or any compound of either element or which may result in the release into air of either of those elements or their compounds.
(g)Unless carried on as part of any other activity within this Schedule—
(i)recovering, concentrating or distilling sulphuric acid or oleum;
(ii)recovering nitric acid;
