Analysis of S, Cl, K, Ca, Cr, Mn, Fe, Zn, Rb, Sr, Mo, Ba and Pb concentrations in the needles of Abies alba and potential impact of paper mill industry
AbstractIn our work we studied samples of Abies alba Mill., - specifically the needles – as a bio indicator of pollution in Ružomberok (not far from the paper mill) and Liptovský Hrádok, Slovakia - the West Carpathians. Samples were collected from two locations, Choč (experimental area) and Čierny Váh (control area). At each locality we selected five field sites, from which we collected samples of needles once a month from May 2016 to February 2017. Various differences in the concentration of elements were detected in the samples based on sample age and the time of year samples were collected. We discovered that concentrations of potassium decreased as the needles aged, while calcium increased. Concentrations of toxic elements increased during autumn and winter and decreased during summer months. Ca, Fe, Rb, Sr, Cr and Pb, were more prevalent in the sample location at Choč (not far from the paper mill) in comparison to the control location.
