Heavy metal accumulation affects growth of Scots pine by causing oxidative damage

Abstract

In this study, some physiological and biochemical parameters related to oxidative stress and the concentration of heavy metals were analyzed in leaves of pine trees (Pinus sylvestris L.) collected from regions suspected of air pollution. Leaves were collected from plants at five different locations near Erzincan, Turkey including the city center and a control area. All leaves were divided into two main parts after a washing procedure. After all pre-procedures in the laboratory, heavy metal analysis was conducted using inductively coupled plasma-optical emission spectrometer (ICP-OES). Data were analyzed statistically, and significant differences were found for plants collected among the different locations. Additionally, electrolyte leakage and physiological parameters such as lipid peroxidation, H 2 O 2 content, chlorophyll content, and activity of the antioxidant enzyme superoxide dismutase were determined as indicators of plant cell stress. Results indicated significant differences between plants at experimental locations vs. the control area in terms of stress parameters; these differences were associated with heavy metal concentrations in plants.

Effects of Prolonged Leaching on the Acute Ecotoxicity of Spruce-Pine Oriented Strand Board for Plants

“…Heavy metals and other inorganic microelements were measured by an inductively coupled plasma optical emission spectrometer. This analytical method is currently recognized as being the most suitable for the analysis of elements in low concentrations of the order of nanograms to mg/L, e.g., [45][46][47]. However, it is not possible to determine biogenic elements and halogens with this method.…”

Ankara’nın Farklı Bölgelerinden Toplanan (Pinus nigra Arnold)’da Ağır Metal Birikiminin Araştırılması

“…Hücreler içinde yer alan örneklerin üzerine deiyonize su eklenerek 50 mL'ye tamamlanmıştır. Son olarak, örnekler filtre kağıdından süzüldükten sonra Spectro Blue Marka ICP-OES cihazında uygun dalga boylarında element okuması yapılmıştır (Anonim, 2015;Osma, 2017 (Yavuzer & Osma, 2018). (Baycu vd., 2006).…”

Inorganic chemical composition of dust deposited on oleander (Nerium oleander L.) leaves

“…containers or funnels, some of them dry others filled with water or liquid paraffin (Adetunji et al 2001;McTanish and Walker 1982;McTanish et al 1997;Tiessen et al 1991), different types of plates, bowls and mats made of different materials (Breuning-Madsen and Awadzi 2005;Moberg et al 1991;Tiessen et al 1991) or using a canopy drip method (Stoorvogel et al 1997). Biological monitoring is also an effective way to measure the level of air pollutants (Baranyai et al 2015;Osma et al 2016;Rai and Panda 2014). It has definite advantages when compared to other techniques.…”
