1 A.P.I.C.E. Common Mediterranean strategy and local practical Actions for the mitigation of Port, Industries and Cities Emissions WP4: Air monitoring and receptor models Kick off meeting Marseille, 8 th July 2010

2 PM sampling IDAEA-CSIC PM10 & PM2.5 with HV samplers. (100 samples of each fraction per year) Quarzt fibre filters 24-hour resolution, 1 location PM and gaseous pollutants monitoring PM10, PM2.5 and PM1 levels Optical counter (GRIMM) + TEOM 10-minutes resolution 1 location NOx, SO2, H2S 10-minutes resolution 1 location NH3, NO2 Weekly sampling (passive dosimeters) 2 locations Conventional meteorological parameters at the sampling site Road traffic flowmeter Number of ships controlled

3 PM analysis IDAEA-CSIC Mineral matter (Al, Ca, Fe, K, Na, Mg, SiO2, CO32-, Ti, P) Trace elements (Li, Cu, Zn, Cd, Ga, Ge, Se, Mo, As, Sb, Sn, Sr, Rb, Rare earths, Pb, V, Ni, Bi, Th, U, etc) OC-EC Sulphate, nitrate, chloride, ammonium Characterization of unload processes and shipping emissions Real time PM monitoring (1-5 minutes) PM sampling and subsequent chemical analysis (as for the filters) XRD identification Other instrumentation? Source apportionment PMF Possibly CMB

4 Sampling Campaings (Univ Provence) Univ- Provence/LCP-IRA (UMR 6264) 1 year observation period (PM2.5 and/or PM10) 2 sampling sites (harbour area and urban background station) 1 sample/week or 1 sample/day for weekly composite sample (tbd) Chemical analysis (PM) Major fraction : OC/EC, sulfates, nitrates, ammonium Organic speciation (~ 60 compounds) : Hopanes, n-alkanes (c18- C36), carboxylic acids (mono and di), cholesterol, levoglucosan, PAH, phthalates, secondary compounds Metals (~ 50) Additional measurements (Collab. AtmoPACA) NOx, SO 2, O 3, PM10 or PM2.5

5 Sampling Campaings (Univ-Provence) Univ- Provence/LCP-IRA (UMR 6264) Source apportionment Chemical Mass Balance (CMB) (organic markers and metals) Vehicular emissions/biomass burning/vegetative detritus/industrial emissions/ship emissions Source profiles will be refined in the course of the project (special focus on ship and industrial emissions, and mediterranean biomass burning) PMF on the entire dataset will be considered {+AMS/PMF during the intercomparison campaign}

6 Sampling & monitoring: Dept. of Physics & Province - Genoa a) Gaseous pollutants, PM levels, meteo from the air quality monitoring network (~ 20 stations in town) with hourly resolution b) Contemporary daily PM2.5 sampling with LVS in two sites c) Monitoring of the particle number concentration (Grimm counter) and of the BC level (aethalometer) with 30 min. resolution, in one site d) intensive PM sampling with hourly resolution (2-stage streaker sampler) and/or with size-resolution (13-stage rotating nanomoudi impactor)

7 Laboratory Analyses: a) PM levels (gravimetric) Dept. of Physics & Province - Genoa b) Elements from Na to Pb (ED-XRF and/or PIXE) c) Possible light elements (H,N,C,O) by IBA d) Ion chromatography e) OC,EC,TC by thermo-optical analysis (SUNSET) f) BC by an optical photometer (home made) g) Ions by ion-chromatography Data Reduction (i.e. Receptor models): a) PMF (but PCA and CMB if needed) b) Home-made apportionment of particle number concentration and size resolved PM speciation.

8 ARPA Veneto : Monitoring PMx (the CMB analytes) Speciation of SVOC on daily (?) PMx filter Direct Thermal Desorption GC-MS no sample prep, automation Quantitation of PAH Alkanes Hopanes & Steranes (biomarkers) Caffeine & Nicotine (Coffee break source)

9 Monitoring Sensor (5-10 min) tracking short time events Given N comparable results (whole campaign) what s the best compromise? N Daily samples 2N half-daily samples 3N 1/3-daily samples 24h 12h 8h

10 Intercomparison: daily or higher time resolution data? Photoelectric Aerosol Sensor (PAS) Surface PAH (Soot) on µm dp range DataRAM 4000 Double beam nefelometer PM10 or 2.5 Diameter

11 Sampling Campaings (UOWM capability) UOWM/Environmental Technology Laboratory Intensive air monitoring campaigns concerning PM1, PM2.5, PM10, TSP fractions. The sampled PM will be collected in quartz fiber or other material filters [equipped with LVS, HVS and Sequential Samplers, weighting room with controlled conditions (T, %RH), portable meteorological station] Chemical analysis of the sampled PM fractions [ equipped with GC-MS, HPLC for PAHs analysis, Ion Chromatography for ionic species and possibility for metal analysis]

12 Sampling Campaings (UOWM capability) UOWM/Environmental Technology Laboratory NO x analyzer [Teledyne Instrument, Chemiluminescence technique] VOCs sampling and analysis of outdoor/indoor air [sampling on Tenax tubes with pumps and passive sampling, Thermal Desorption Autosampler (TDSA) for VOC analysis with GC-MS, GC-FID for passive sampling analysis]

13 Summary (or To do list ) PM levels available in each area: chemical speciation on PM2.5 only? On which time base? (daily, weekly, etc) How many sites? How many samples (along the one-year local campaigns)? Gaseous tracers available in each area with high time resolution Can we single out a minimum set of tracers to be measured in each area? Can we find the way to share expertise/analytical capabilities? Specific problems and/or intensive campaign at local level only Can we limit the source apportionment tools to PMF and CMB only? Can we run both in each area? What should you learn from the common experiment in Marseille in view of the long local campaigns? How can we arrive at the next meeting (Barcelona, January 2011) with all these issues fixed?

14 A possible way to proceed a) Written proposal diffused by a coordinator within sept to a limited number of contact persons (Pey, Marchand, Prati, Latella,Evangelos?) b) Feedbacks from all the partners within nov c) Second (refined) proposal within dec d) Final decision at the Jan meeting.
