The combustion of pruning residues of olive trees in field is a common practice in South of Italy. Since fields are usually close to densely populated areas, the biomass burning emission may cause seasonally increasing exposure to air pollutants and may lead to a potential health risk for the population. The goal of this work was to carry out the chemical characterization of PM deriving from open burning of agricultural biomass and to identify tracer species or concentration ratios characteristics of this source. The collected data showed that during open burning of olive tree residues, PM10 mean concentration was about fifty times higher than PM10 collected at background site in no biomass burning event. Moreover the particulate matter composition was especially enriched in K, OC and Polyciclic Aromatic Hydrocarbons (PAHs) such as benz[a]anthracene and benzo[a]pyrene.

Abstract
The combustion of pruning residues of olive trees in field is a common practice in South of Italy. Since fields are usually close to densely populated areas, the biomass burning emission may cause seasonally increasing exposure to air pollutants and may lead to a potential health risk for the population. The goal of this work was to carry out the chemical characterization of PM deriving from open burning of agricultural biomass and to identify tracer species or concentration ratios characteristics of this source. The collected data showed that during open burning of olive tree residues, PM10 mean concentration was about fifty times higher than PM10 collected at background site in no biomass burning event. Moreover the particulate matter composition was especially enriched in K, OC and Polyciclic Aromatic Hydrocarbons (PAHs) such as benz[a]anthracene and benzo[a]pyrene.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
