“…To the best of our knowledge, this is the first air quality network which provides continuous concentration measurements of so many pollutants in a such small area, even when compared, for example to the very efficient observing network operating near the five refineries in the San Francisco Bay Area described in a recent comprehensive report by Fujita and Campbell (2013). More common monitoring strategies are mainly devoted to the study of volatile organic compounds (VOCs) and sulfur dioxide near refineries (Baltrėnas et al, 2011;Lin et al, 2008) or near industrial parks, including petrochemical facilities (Liu et al, 2008;Hsieh et al, 2006). Nevertheless, more investigation should be done.…”

Abstract. The Val d'Agri area (southern Italy) hosts one of the biggest onshore European reservoir and the largest oil/gas pre-treatment plant, named Centro Olio Val d'Agri (COVA), located in a rural/anthropized context. Several hazards are associated with this plant. These are mainly represented by possible impacts of the COVA atmospheric emissions on the local air quality and human health. This work uses a novel approach based on the integration of air quality measurements from the regional monitoring network, additional experimental measurements (i.e. sub-micrometre particulate matter (PM 1 ) and black carbon (BC)) and advanced statistical analyses to provide a preliminary evaluation of the Val d'Agri air quality state and give some indication of specific areas potentially affected by COVA hazards. Results show that the COVA plant emissions have a particular impact on the air quality of the area closest to it. In this area several pollutants specifically related to the COVA combustion processes (i.e. nitrogen oxides, benzene and toluene) show the highest concentration values and significant correlations. The proposed approach represents a first step in the assessment of the risks associated with oil/gas exploration and pretreatment activities and a starting point for the development of effective and exportable air quality monitoring strategies.

“…The ratio T/B (toluene/benzene) enables identification of industrial combustion of coal and combustion in domestic furnaces. Domestic furnaces are characterized by the value of the T/B ratio from 0.48 to 0.82, while industrial combustion ranges from 0.84 to 0.98 [8]. Industrial combustion was identified in winter samples -Radvanice (2013) and Poruba (2013Poruba ( , 2014.…”

Abstract. Airborne particles were analysed with aim to distinguish emissions from different sources -coal combustion in large power plants, local heating and transport. Emissions from large facilities were sampled for comparison. Samples of particles collected on filters were analysed by pyrolysis gas chromatography with mass spectrometric detection. Organic substancesgeochemical and anthropogenic markers and their diagnostic ratios were determined for particles of size under 1µm in ambient concentrations and particles of size under 2.5 µm in emissions. The results obtained in the industrial city of Ostrava, Czech Republic, showed that the diagnostic ratios-toluene/benzene, pristane/phytane, and undifferentiated/differentiated alkanes can be effectively applied to distinguish the origin of emissions.

“…VOCs emitted from industrial sources into the atmosphere may cause pollution on a local scale. In an industrial city, VOC emissions could not only be the result of industrial sources, but also could be affected by surrounding traffic sources (32). We found that concentrations of urinary t,t-MA, 2-MHA, 3-MHA, phenol, and MEK in outdoor workers (operator, repairman, site man, exploiter, lab sample man, and tipper) were significantly higher than that in indoor workers (security officer, lab staff, and supervisor).…”

Received: July 2015, Accepted: August 2015 Background: Volatile organic compounds (VOCs), including carcinogens and toxic compounds, are produced in petrochemical industries. We undertook this study in order to study workers' respiratory exposure to different VOC concentrations and compare the results with the urinary levels of its metabolites and study the correlation between them in petrochemical industries. Materials and Methods: Exposure to benzene, toluene, xylene isomers, phenol, and methyl ethyl ketone (MEK) was evaluated in 104 male subjects using personal sampling pump and charcoal sorbent tube at the breathing zone and analyzed using gas chromatography-mass spectrometry (GC-MS). The urine samples were analyzed using high-performance liquid chromatography (HPLC-UV) and gas chromatography-flame ionization detector (GC-FID). Results:The mean concentration of urinary trans,trans-muconic acid (t,t-MA), was 1431 µg/g creatinine and hippuric acid, methyl hippuric acid, phenol, and MEK were, 0.394, 0.444, 0.098 g/g creatinine, and 0.15 mg/l. The mean concentration of benzene in the breathing zone was greater than the threshold limit value (TLV) recommended by the American Conference of Governmental Industrial Hygienists (ACGIH). Conclusions:In this study, a more significant relationship was found between benzene in breathing zone and urinary t,t-MA in those exposed to benzene in concentrations higher than 1 ppm (r 2 = 0.89) than lower than 1 ppm. Moreover, the same results were observed for other hydrocarbons and their level of urinary biological index. A more significant relationship was observed between phenol in breathing zone and urine through exposure to airborne phenol in concentrations of higher than 0.049 ppm than lower than 0.049 ppm (r 2 = 0.75). The relationship between MEK in breathing zone and urinary MEK was more significant in concentrations of higher than 0.1 ppm (r 2 = 0.79) than lower than 0.1 ppm.
