In North Lebanon, the region of Chekka represents a group of villages scattered around an industrial complex of cement factories and a chemical fertilizer industry. In order to understand the nature of atmospheric aerosols in this region, 20 samples of atmospheric total suspended particles were collected next to the region of industrial activities. The analysis of inorganic water soluble ions and metal composition of the sampled particles was achieved using ion chromatography (I.C.) and inductively coupled plasma-mass spectrometer (ICP-MS). Higher global particle concentrations and NO3-concentrations were identified inthe sites near the cement factories. However, this nitrate concentration was attributed to longrange transport and accumulation phenomenon happening in the region. Peaks in potassium concentrations were confirmed in some samples and most probably emitted by a secondarysource of emissions, possibly from local biomass combustion. On the other hand, low levels ofcalcium were identified in the samples, despite the presence of cement quarries next to thesampling sites, because of the dominant low wind activity during the sampling period.
