Resumen:
The objective of this work was the evaluation of the environmental pollution within the urban area of Mar del Plata (Argentina), using lichen species as biomonitors. Sampling campaigns were realized in 3 green areas located on the city centre, close to main avenues, where vehicular emissions are considered the main pollution source. The collected species was Parmotrema pilosum and magnetic properties were determined using environmental magnetism measurements: magnetic susceptibility, anhysteretic and isothermal remanent magnetizations. Associated parameters and ratios were calculated and used. The results showed that magnetite-like minerals are the main magnetic phase with a grain size distribution ranging between 0.1 and 1 um.
