Accumulation of heavy metals in soil and litter of roadside plantations in Western Polissia of Ukraine

Abstract

The article presents the results of a study on the influence of roadside forest belts of different species composition on the accumulation of heavy metals in soil and litter along roads of international and national importance in the conditions of Western Polissia of Ukraine. Mobile forms of Cd, Cu, Pb and Zn in soil and forest litter samples were determined in ammonium acetate extract buffer by atomic absorption spectrometry. The analysis of the content of heavy metals, their comparison with the maximum allowable concentrations depending on the composition of plantations and the category of the highway have been done. It is confirmed that roadside forest belts perform important functions in the accumulation of heavy metals in soil and forest litter. It is confirmed that roadside forest belts perform important functions in the accumulation of heavy metals in soil and forest litter. Among all the pollutants studied, the concentration of cadmium was the lowest and that of zinc the highest (especially in forest litter). Lead and copper in this indicator occupied an intermediate position. Despite the different species composition of plantations, the coefficient of concentration of heavy metals in the soil did not exceed the maximum allowable concentrations and was on average in the range of 0.10–0.20 of these indicators. The greatest effect of delaying the migration of heavy metals was observed in forest litter. Therefore, in order to effectively use the biological barrier along the roads, it is necessary to create linear protective belts of deciduous species with Acer platanoides, Betula pendula, Carpinus betulus and Tilia cordata, which give a rich annual litterfall.

Performance analysis of protective functions of forest plantations of the Lviv railway line (Ukraine)

“…Atomic absorption spectrophotometer is a laboratory stationary indicating and self-recording device of periodic action. The determination of heavy metal is carried out according to the approved "Methodology of measurements using the C 115-M1 atomic absorption spectrophotometer" (Maksimtsev et al, 2021;Trokhymenko et al, 2012). For the pollution level determination sampling was carried out at different distances from the source of pollution, namely (Fig.…”

Effect of heavy metals on soil and crop pollution in Ukraine – a review

“…The dispensation of Cd, K, Na, Pb, and Zn during incineration at temperatures up to 960 °C was online monitored, and some insights were discovered about the behavior of such metals and the chemistry implicated in the volatilization process (Tarik et al, 2021). At the same time, in the other monitoring studies the mobile forms of Cd, Cu, Pb and Zn were determined in ammonium acetate buffer extract by atomic absorp-tion spectrometry (Maksimtsev et al, 2021).…”

“…Such plantings are capable of accumulating atmospheric carbon depending on the characteristics of their aboveground phytomass (Khodash, 2010;Ziegler et al, 2016). S. Maksimtsev et al (2021) noted that in addition to these factors, windbreaks, especially roadside windbreaks, play a crucial role in protecting adjacent areas from the spread of heavy metals generated by traffic emissions. These plantations serve a dual function: on one hand, they protect transportation routes from adverse natural and climatic factors and the dispersion of harmful emissions from vehicles, and on the other hand, they provide protection for adjacent agricultural fields.…”
