This map shows the location of the National Soil Inventory of Scotland sampling points. The colour of the symbol relates to the lead concentration of the topsoil found at that point (in parts per million of air-dried soil). The soils were sampled between 1978 and 1988 as part of the National Soil Inventory of Scotland.
The Lead (Pb) concentration (parts per million of air-dried soil) is shown in the following categories:
|Pb concentration greater than 168.3 ppm|
|Pb concentration between 60.1 and 168.3 ppm|
|Pb concentration between 28.0 and 60.1 ppm|
|Pb concentration between 16.5 and 28 ppm|
|Pb concentration between 7.6 and 16.5 ppm|
|Pb concentration less than 7.6 ppm|
Lead (Pb) concentration in the topsoil is reported in parts per million (ppm) of air dried soil from the National Soil Inventory of Scotland (NSIS 1978-88) dataset. Data was collected at sample locations arranged on a 10 km grid across the country. The map shows the location of each sampling point and the lead concentration in the topsoil.
