- The impact of emissions on air quality during the production of olive oil is analysed.
- The biomass source is identified by PMF as the main contributor to PM10.
- High concentrations of organic carbon and levoglucosan are present in PM10 fraction.
- Burning of olive tree wood and waste olive are distinguished.
The inorganic and organic geochemistry of aerosol particulate matter (APM) was studied in a major olive grove area from Southwest Europe (Baena, Spain). The biomass consists of olive tree branches and the solid waste resulting of the olive oil production. Moreover, high PM10 levels were obtained (31.5Â Î¼gÂ mâÂ 3), with two days of exceedance of the daily limit of 50Â Î¼gÂ mâÂ 3 (2008/50/CE; EU, 2008) during the experimental period. A high mean levoglucosan concentration was obtained representing up 95% of the total mass of the isomers analysed (280Â ngÂ mâÂ 3), while galactosan and mannosan mean concentrations were lower (8.64Â ngÂ mâÂ 3 and 7.86Â ngÂ mâÂ 3, respectively). The contribution of wood smoke in Baena was estimated, representing 19% of OC and 17% of OM total mass. Positive matrix factor (PMF) was applied to the organic and inorganic aerosols data, which has permitted the identification of five source categories: biomass burning, traffic, mineral dust, marine aerosol and SIC (secondary inorganic compounds). The biomass burning category reached the highest mean contribution to the PM10 mass (41%, 17.6Â Î¼gÂ mâÂ 3). In light of these results, the use of biomass resulting from the olive oil production for residential heating and industry must be considered the most important aerosol source during the winter months. The results of this paper can be extrapolated to other olive oil producing areas in the Mediterranean basin. Therefore, a fuller understanding of this type of biomass combustion is required in order to be able to establish appropriate polices and reduce the environmental impact on the population.
