Toxic chemical pollutants detected in lichens and mosses in Irati forest

A study by the IBeA research group of the University of the Basque Country (UPV/EHU) revealed relatively high concentrations of three groups of organic pollutants. The study concluded that some of these pollutants come from nearby urban areas; others originate from combustion processes currently taking place in agriculture; and finally the ones corresponding to pollution caused by pesticides and some electrical insulators before they were banned several years ago.
