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.
The study aims to assess the identification of the specific species of plants for selection of certain plant species and utilization of selected one�s in experimental biomonitoring studies.The purpose of the proposed study was to develop and apply new techniques, methods and methodologies for air quality assessing in the context of climate change and updating of international environmental studys. The novelty of the active biomonitoring method using plants is an innovative research area for the National Research and Development Institute for Industrial Ecology in terms of the use of sentinel species. The first stage research activity was aimed to identify plant species with specific response to certain environmental pollutants, in our case, ozone. By exposing higher plants (from the Solanaceae family) to various environmental conditions, a direct impact measurement of ground-level ozone was considered - as an indicator of environmental pollution (air) - there was a significant difference relationship between soil level ozone variation and foliar necrosis.
Nowadays, the air pollution has become a major environmental problem due to rapid increase of industrialization and anthropogenic activities which led to climate change. Air pollution is considered as a harmful agent for human health. Different classes of gaseous pollutants (SOx, NOx) are continuously released in air and perceived/recognized as pollutants. Among the biological models, plants could give us information related with pollution range in a monitored area, analyzing injuries caused on the leaves surfaces. The aim of this study was to identify and select certain species of plants for using them in experimental biomonitoring studies. An experimental fumigation system with a closed fumigation glasshouses maintained under defined conditions with environmental control and pollutant delivery was used to study the effects of air pollution on plants species. The relative degrees of injury as a response of plants to pollutants fumigation were assessed. Considering the sensitiveness degree to pollutants, the indigenous tobacco Nicotiana rustica proved to be the most sensitive followed by cultivated tobacco Nicotiana tabacum and least sensitive Petunia hibrida. Future researches will focus on field biomonitoring.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
