Theobjective of this work was the evaluation of the environmental pollution withinthe urban area of Mar del Plata (Argentina), using lichen species asbiomonitors. Sampling campaigns were realized in 3 green areas located on thecity centre, close to main avenues, where vehicular emissions are consideredthe main pollution source. The collected species was Parmotrema pilosum and magnetic properties were determined using environmentalmagnetism measurements: magnetic susceptibility, anhysteretic and isothermal remanentmagnetizations. Associated parameters and ratios werecalculated and used. The results showed that magnetite-like minerals arethe main magnetic phase with a grain size distribution ranging between 0.1 and1 mm.
