Abstract. The HOVERT (HOrizontal and VERtical Transport of ozone and particulate matter) campaign held in the Berlin Brandenburg area in Eastern Germany from September 2001 to September 2002 allowed to collect a unique data set of the aerosol chemical speciation (daily averages) at traffic, urban and rural sites. These observations are used for a thorough evaluation of the aerosol part in the REM-CALGRID model (RCG) developed at the Free University of Berlin (FUB). For inorganic ions (sulphate, nitrate and ammonium), simulated annual averages agree to observations within ±30% at more than half of the sites and always within a factor of two. Correlation coefficients are larger than in previous studies for SO 2− 4 and NH + 4 (>0.7). For nitrate, less elevated correlations, 0.4-0.7 in the cold season, 0.2-0.4 in the warm season, are encountered. To our knowledge, this is one of the first comparisons of air quality model simulated elemental and organic carbon (EC and OC) with daily observations for a whole year. It suggests an overestimation of EC and OC emissions in the Berlin area (through a scaling techniques between EC, OC and NO x and when assuming correct NO x emissions), and an underestimation of EC and OC at rural sites. Secondary organic aerosol (SOA) formation, recently introduced into the model (SORGAM module, Schell et al., 2001), is simulated as a very variable process, SOA levels varying from close to zero for most days to more than 5 µg/m 3 . Correlation between simulated SOA to observed OC is about 0.6, indicating that simulated variability partly corresponds to reality.

Institut za medicinska istra`ivanja i medicinu rada, Zagreb, HrvatskaUgljik (lat. carbo) u elementarnom stanju pojavljuje se kao dijamant, grafit, fuleren i crni amorfni ugljik. Crni amorfni ugljik nalazi se i u lebde}im ~esticama u atmosferi, a glavni oblici su: elementarni (EC), organski (OC) i karbonatni (CC) ugljik. Atmosferske ~estice ugljika emitiraju se iz vi{e od 70 razli~itih vrsta izvora one~i{}enja zraka. EC je primarni one~i{}iva~ koji nastaje nepotpunim izgaranjem fosilnih i biljnih goriva, a pojavljuje se jo{ i kao ~estice ~a|e te ga nalazimo i u sedimentima, tlima i ledu. Mnoga kvantitativna odre|ivanja EC temelje se na njegovoj kemijskoj inertnosti, termi~koj stabilnosti i opti~kim svojstvima. Organski spojevi kao {to su policikli~ki aromatski ugljikovodici (PAU), poliklorirani bifenili (PCB), poliklorirani dibenzo-p-dioksini i furani, polibromirani difenileteri te druga organska one~i{}enja nastaju procesima izgaranja i stvaranja sekundarnih organskih aerosola, a ubrajaju se u organski ugljik (OC). Svrha je ~lanka opisati razli~ite oblike ugljika u lebde}im ~esticama u zraku, njihov negativni u~inak na zdravlje ljudi, klimu i atmosferu te opisati metode za njihovo odre|ivanje.

“…Actually, carbon may be present in atmosphere as carbonate too (from the resuspension of crustal material containing carbonate species); however, this contribution is mostly negligible [16]. Radiocarbon measurements have been demonstrated as a powerful tool to study the sources of the carbonaceous aerosol fraction [17].…”

“…Carbon is a major constituent of particulate matter in the atmospheric aerosols [16]. It is present in the aerosol either with a graphitic microstructure or as organic compounds; therefore, the total carbon (TC) present in the aerosol can be divided into elemental carbon (EC) and organic carbon (OC).…”

Radiocarbon is one of the most widespread radionuclides in nature. Although it is probably best known for dating in archaeology, in the case of the general public, it represents a useful tracer to study our environment, both in the past and nowadays. For instance, carbonaceous particles, which are in many cases the most abundant among aerosols constituents, are believed to play a major role in both health and climatic effects of aerosols. In particular, measurement of radiocarbon concentration in particulate matter samples can give information on the contributions of the fossil fuels combustion and of natural sources *
