Receptor models based on chemical composition of particulate matter PM), such as Chemical Mass Balance (CMB) and Positive Matrix Factorization (PMF) are useful means for source apportionment but their results are The purpose of this paper was to analyze pollutant concentration in urban and industrial aria of Slavonski Brod so as determine correlation with meteorological parameters. Due to results of pollution measurements, Fourier analysis was applied to these time series. H2S, O3, NO2. SO2 and PM2.5 particles were measured in 2010. During that time hourly concentration of pollutants were measured and 3 O2 (g) <=> 2 O3 (g) U prirodi ozon nastaje i u nižim slojevima atmosfere (u troposferi) kao i u višim slojevima (u stratosferi). Dok njegovo prisustvo u troposferi predstavlja problem, u stratosferi je neophodan za održavanje zdravlja i života na Zemlji. Što je kemija?

Apart from false cycles and those with highest intensity, half-day cycles were found for NO2 concentrations. Same cycles were also discovered in year 2012 for hourly concentrations of SO2 and O3. kemija.

2 days ago · Alotropske modifikacije su različiti molekulski ili kristalni oblici istog elementa. Iako se radi o istom elementu, alotropi zbog razlike u strukturi imaju različita fizikalna i kemijska svojstva. Čitav niz elemenata (ugljik, željezo, kositar, selenij, bor, silicij, kobalt) javlja se u više alotropskih modifikacija. U ovom radu opisane su alotropske modifikacije ugljika, fosfora, sumpora - H2, O3, S8 - Kisik ima u svim spojevima oksidacijski broj –II, osim u peroksidima -1 - CaO, Na2O2 - Oksidaciski broj elemenata 1.
