Výskyt "black carbon" v ovzduší v ostravsko-karvinské aglomeraci

Abstract

The paper deals with the black carbon particles. Black carbon (BC), mainly generated from incomplete combustions of bio-fuel, fossil fuel and biomass burning. BC aerosol, accounting for a minor fraction of atmospheric aerosols, is attracting increased attention due to its impact on air quality, human health, and climate change. This paper discusses about variations in BC concentrations over different timescales, including annual, weekly and seasonal changes, were studied from 9.1.2012 to 21.3.2013 in Ostrava-Zábřeh. The measurement were made every day and BC aerosols were measured using an portable aethalometer (AE-42). Furthermore, It was studied influence of meteorological parameters on the BC concentrations. It was detected only polynomic dependence between concentrations BC and temperature. In the last chapter It was proved significant positive correlations between BC concentration and PM10.
