Particulate matter (PM) deposited on Platanus acerifolia tree leaves has been sampled in the urban areas of 28 European cities, over 20 countries, with aim testing leaf particles as indicator atmospheric PM concentration and composition. Leaves have collected close to streets characterized by heavy traffic within parks. Leaf surface density, dimensions, elemental composition compared magnetic content, discussed connection air quality data. The quantity size were mainly dependent regional...
Outdoor dust as a pollutant is also transit environment for different pollutants emphasizing heavy metals. Commonly, it urban population, who exposed to the maximal adverse impact of and associated pollutants. In most cases, atmosphere researches are implemented on few permanent monitoring stations. Data obtained from these stations cannot be sufficient enough provide real picture atmospheric pollution. The detailed information synchronous instrumental sampling (aspiration) studies indicator...
Mercury (Hg) contamination is a frequently debated issue in environmental research. In this study, the distribution and ecological health risk of Hg soil outdoor dust from 19 kindergartens Vanadzor city were investigated. comparison with other cities, concentrations samples retrieved significantly low constituting 0.03–0.42 mg/kg 0.025–0.05 respectively. The total determined using XRF-spectrometry, detection limit 3·10−4 mg/kg. geostatistical analyses suggested relatively high only 4...
The main goal of this research was to estimate heavy metals (HMs) (molybdenum (Mo), copper (Cu), nickel (Ni), cadmium (Cd)) contents in crop leaves through multispectral satellite imagery. During the acquisition a SPOT 7 image (28 July 2017) situ sampling (38 samples) done from potatoes and beans growing close mining town Kajaran (Armenia). To HMs contents, multivariate regression (multiple linear (MLR), partial least squares (PLSR)), artificial neural network (ANN) were used. As input data...
Mercury is a widespread environmental pollutant becoming crucial health concern as result of natural and anthropogenic releases. Understanding Hg distribution pattern between different functional urban areas needed for pollution control impact assessment. Therefore, in this paper soil spatial distribution, level evaluation, mercury-induced risks were studied, (355 samples) kindergartens (18 Vanadzor. Geospatial mapping the geostatistical analysis suggest that concentration entire area...
Abstract This research aimed to assess the ecological status of Hrazdan river section flowing through Yerevan. The distribution toxic elements (Cr, V, As, Zn, Cu, Ni, Co, Mn, Pb, Ti, Mo, Fe, Ba), bottom sediments pollution level and risks, were assessed employing contamination factor (CF), enrichment (EF), potential risk index (RI) geoaccumulation (I geo ). On sampling sites, water quality parameters (turbidity, DO, conductivity (EC), salinity, TDS, pH, T°C) measured, as well. correlation...
