TEMPORAL VARIATION OF PAHS IN SOILS FROM THE BIOBÍO REGION: CENTRAL SOUTHERN CHILE
In this short communication we describe the temporal variation of PAHs fingerprints and burden in surface soils from coastal and central valley sites in South Central Chile, with different anthropogenic influence. PAHs were extracted with accelerated solvent extraction and measured by HPLC with fluo...
