The new data and maps, which are freely available to the public on the Geological Survey Ireland website, show that the soils tell a human story as well as a geological one. Industrialisation has led to elevated levels of mercury, lead, and copper around cities. The burning of fossil fuels has resulted in high levels of the element tin in the soils around cities and towns. The maps also show the impact of farming, with evidence of improved soil fertility through the application of phosphorus and other fertilizer components. The new data can also highlight areas which are deficient in certain nutrients or elements important for crop growth or animal health.
