Abstract
This paper explores the first attempt at determining the levels of atmospheric heavy metal contamination in the Zonguldak province through the analysis of moss (Hypnum cupressiforme Hedw.). Sampling was performed at 24 sites after a wet period to avoid contamination from soil compounds in the province. Dried samples, which were unwashed but cleaned of soil particles and other extraneous material, were digested with HNO3/HClO4. Concentrations of heavy metals (Fe, Cu, Pb, Cr, Co, Ni, and As) were analyzed by ICP-OES to estimate the geographic distribution of the atmospheric heavy metal depositions. The general order of the concentrations of the heavy metal content in Hypnum cupressiforme Hedw. was observed to be Fe > Pb > Cu > Ni > Cr > As > Co. Mean levels of the measured elements were higher when compared to European levels. Arsenic, iron, and chromium were the most elevated elements when compared with European data. The mean concentrations of these elements in the studied area were 8.3 (Co), 6.7 (Fe), 5....
