Sensitive bioindicator plants studies, under the environmental conditions of climate change impact

Abstract

Air pollution is a serious problem in many heavily populated and industrialized areas in the world. It affects vegetation, and also human health. The diversification of emission sources, among them vehicles, industrial processes, waste burnings and fuel storage, creates zones with different species and concentrations of air pollutants. In this paper was studied the excessive accumulation of toxic metals such as Al, Cr, Ni, Zn, Pb in vegetation as a risk factor for ecosystem and also for human health. The purpose of the study was to establish an optimal method of determination for toxic elements accumulation in leaves, using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). These results made to suppose that, visible and analyzed responses of in in-situ exposed bio monitors compared with heavy metal accumulation depended on the atmospheric situation during the period of exposure, which could assess the efficiency of biomonitoring programs in the region. The advantage of this study consists in new and appropriate approach using a friendly methodology for air monitoring and favoring the development of a circular and sustainable economy.

Bioassessment of water quality of surface waters using diatom metrics

“…Bioindicators in the aquatic ecosystem give crucial responses to pollution gradient, which can provide valuable information about health and the overall ecological status of environments (Rott et al, 1999;Kelly et al, 2008;Birk et al, 2012;Toudjani et al, 2017;Çelekli et al, 2019b). Concerning that, tolerances and sensitivities of bioindicator species have been used to investigate and assess the potential effects of environmental pollutants on living things (Rott et al, 1999;Kelly et al, 2008;Çelekli et al, 2019b;Cozea et al, 2020). The advantage of using bioindicators is the integration of these organisms in the evaluated habitats (Lobo et al, 2016;Cozea et al, 2020).…”

The advantage of using bioindicators is the integration of these organisms in the evaluated habitats (Lobo et al, 2016;Cozea et al, 2020). Also, they show universal behavior in different ecosystems, which is important for comparing pollution in different continents or ecosystems (Rott et al, 1999;Smol and Stoermer, 2010;Lange-Bertalot et al, 2017;Morales et al, 2020).…”
