Abstract:
The fertilizer industry related to the whole chain of production, storage, transport and use causes a potential pollution of air, water, soil and vegetation. A local sampling monitoring network was developed around Turnu Magurele fertilizer plant in Romania. Samples of mosses, soil, tree leaves and crops were analyzed by neutron activation analysis for more than 35 chemical components. This paper reports the distribution of 39 trace elements in the moss-biomonitor Hypnum cuppresiforme used to study atmospheric deposition in the examined area. The results obtained evidence for a local pollution of the area exposed to the emissions of the phosphate fertilizer local industry, following a gradient along the Danube River wind rose profile. The vegetation input of trace elements from soil is compared with inputs from atmospheric deposition, and these inputs were evaluated in relation to the vegetation content. The study established that cadmium, strontium and rare earths are the major elements as regards fertilizer input.
