Marginal citations

M1: The figures for Margins of Tolerance for each of the relevant pollutants given in this Schedule are calculated from those given in Annex I of Directive 99/30/EC (O.J. No. L 163, 22.4.99, p.41). This gave a figure above the limit value for each relevant pollutant, reducing by equal percentages from the date of entry into force of that Directive in 1999.
