Tellus 2019 - Stream Sediment 'C'

​​​​​TypeAccess

Sample media: <150 µm fraction stream sediment 'C'

Coverage: Survey areas G1, G2, G3 and G4 (FA ICP-MS only). Including counties Donegal, Sligo, Leitrim, Cavan, Monaghan, Louth, Mayo, Galway, Roscommon, Clare, Tipperary, Waterford, Kilkenny, Carlow, Wexford, Wicklow, Kildare, Dublin.

Analytical methods: Laboratory tests are for multi-element total analyses of major, minor and trace elements by X-ray fluorescence spectrometry (XRFS); and for gold, palladium and platinum precious metals by lead-collection fire assay fusion with analysis by inductively coupled plasma mass spectrometry (ICP-MS).

Survey years: 2011-2017

Tellus 2019 - Stream Water 'W'

​​​​​TypeAccess

Sample media: <0.45 µm filtered stream water 'W'

​Coverage: Survey areas G1, G3 and G4. Including counties Donegal, Sligo, Leitrim, Cavan, Monaghan, Louth, Mayo, Galway, Clare, Tipperary, Waterford, Kilkenny, Carlow, Wexford, Wicklow, Kildare, Dublin.

Analytical methods: Field determinations are of pH, specific electrical conductance, and total alkalinity to assess bicarbonate concentration. Laboratory tests are for anions by ion chromatography (IC); multi-element major, minor and trace elements by inductively coupled plasma mass spectrometry (ICP-MS); and non-purgeable organic carbon (NPOC).

Tellus 2019 - Shallow Topsoil 'A'

​​​​​TypeAccess

​Sample media: <2 mm fraction soil up to 0.20 m depth 'A'

Coverage: Survey areas G1, G3 and Dublin/Galway periurban. Including counties Donegal, Sligo, Leitrim, Cavan, Monaghan, Louth, Mayo, Galway, Dublin, Meath, Kildare, Wicklow.

Analytical methods: Laboratory tests comprise: soil pH (CaCl2); loss-on-ignition at 450°C; multi-element total analyses of major, minor and trace elements by X-ray fluorescence spectrometry (XRFS); and multi-element partial extract analyses of major, minor and trace elements by aqua regia digestion with an ICP finish.
