Estimation of element deposition derived from road traffic sources by using mosses

Simulation of traffic-related aerosol dispersion

“…The determined dispersion curves depend on the parameters m, describing sedimentation, and on β, which characterises the expansion of the turbulent wake of vehicle flow. Since the obtained concentration of the aerosol particles coincides well with the experimental data provided by Zhu et al [32] and the shape of its functional dependence on the distance from the roadway agrees with the results of [33,34] we assume that the proposed model can be successfully used to model the dispersion of aerosol particles near roadways.…”

“…A cross wind translates the pollutant cloud away from the road and the particles are being influenced by gravity, particle buoyancy and thermal plume rise effects. The obtained pollutant concentration function coincides well with the experimental data obtained by Zhu et al (2011), Grigalavičienė andRutkovienė (2006), andZechmeister et al (2005). …”

Determination of Some Heavy Metals Levels in Funaria Hygrometrica in Dutsinma Town of Katsina State, Nigeria

“…Tree barks and their leaves remain in the environment for a long period and are sensitive indicators of the environmental contamination with heavy metals, sulphur and fluorine (Ayodele and Ahmed, 1996). Onianwa (2001) and Zechmeister et al (2005) have independently studied and determined heavy metals using sediments and organisms. But, of all plants, mosses and lichens have been found to be the best bio indicators (Gerdol et al, 2000;Fernandez et al, 2002).…”

Using “bryophytes and their associated testate amoeba” microsystems as indicators of atmospheric pollution

“…purum is used to biomonitor atmospheric pollution (Zechmeister et al, 2005;Amblard-Gross et al, 2002;Fernández and Carballeira, 2001). In France, this bryophyte species is used by Fig.…”
