“indicative measurements” (“mesuriadau dangosol”) means measurements which meet data quality objectives that are less strict than those required for fixed measurements;
“margin of tolerance” (“ffin goddefiant”) means the percentage of the limit value by which that value may be exceeded in a given year;
“oxides of nitrogen” (“ocsidau nitrogen”) means the sum of the volume mixing ratio (ppbv) of nitrogen monoxide (nitric oxide) and nitrogen dioxide expressed in units of mass concentration of nitrogen dioxide (μg/m3);
“PM10” (“PM10”) means particulate matter which passes through a size-selective inlet as defined in the reference method for the sampling and measurement of PM10, EN 12341, with a 50% efficiency cut-off at 10 μm aerodynamic diameter;
“PM2·5” (“PM2·5”) means particulate matter which passes through a size-selective inlet as defined in the reference method for the sampling and measurement of PM2·5, EN 14907, with a 50% efficiency cut-off at 2,5 μm aerodynamic diameter;
“pollutant” (“llygrydd”) means any of the following—
arsenic,
benzene,
benzo(a)pyrene or other polycyclic aromatic hydrocarbons,
cadmium,
carbon monoxide,
lead,
mercury,
nickel,
nitrogen dioxide,
oxides of nitrogen,
ozone,
PM10,
PM2·5,
sulphur dioxide;
“polycyclic aromatic hydrocarbons” (“hydrocarbonau aromatig polysyclig”) means those organic compounds composed of at least two fused aromatic rings made entirely from carbon and hydrogen; and
“total deposition rate” (“cyfradd llwyr ddyddodiad”) means the total mass of pollutants which is transferred from the atmosphere to surfaces such as soil, vegetation, water and buildings in a given area within a given time.
