“…However, the plantain peels used for this research were harvested in a farm located in a small town far away from commercial and industrial activities with little or no vehicular movements/emissions. This is justifiable as literature has proven that vehicular emissions are associated with and even described as 'first line sources' of heavy metal pollutants (Poszyler-Adamska and Czerniak, 2007). Also, lead, cadmium and nickel have been reported as the most prevalent heavy metals pollutant in vehicular emission due to their presence in fuel as anti-knocking agents (Suzuki et al, 2009;Atayese et al, 2010).…”

This study investigated the nutraceutical potential of ripe and unripe plantain fruit peels which are commonly discarded as food wastes. Proximate and mineral analyses of the samples were performed as per the standard methods of the Association of Official Analytical Chemists. Preliminary phytochemical screening of aqueous, acetone and methanol extracts of the peels was also carried out in accordance to standard methods. From the results of the study, acetone extract of the unripe peel showed the presence of eight phytochemicals while its ripe peel showed the presence of four. Aqueous and ethanol extracts of both peels showed the presence of same phytochemicals i.e., terpenoids, cardiac glycosides, phenols, flavonoids, alkaloids, reducing sugars and saponins. Meanwhile, tannins was absent in all three solvent extracts of both peels. Fat, ash, crude fibre and carbohydrate contents of the unripe peel were higher than those of the ripe. However, moisture and protein contents of the ripe peel were significantly higher (P < 0.05) than those of the unripe. Of all the nine essential minerals assayed (K, Na, Mg, Ca, P, Fe, Zn, Mn, Cu), concentrations of all except calcium were significantly higher (P < 0.05) in the unripe peel than those of the ripe peel. Notably, none of the heavy metals (Co, Cr, Cd, Pb, Ni) assayed was detected in both samples. This study concludes that ripe and unripe plantain fruit peels could serve as promising sources of nutrients and bioactive compounds essential for the health of both livestock and humans.

“…These activities send trace metals into the air and the metals subsequently deposited into nearby soils, which are absorbed by plants on such soils. Public motor roads affect natural environment to a large extent because automobiles act as line sources of heavy metal pollutants (Poszyler-Adamska & Czemiak, 2007). Samples of soil from lands near motorways in some urban cities in Nigeria such as Jos, Osogbo, Ibadan and other cities, have been studied (Abechi, et al, 2010;Fakayode & Olu-Owolabi, 2003;Onianwa, 2001; Ihenyen, 1998).…”

The research was designed to ascertain the concentrations of heavy metals (Cu, Pb, Zn, Ni, Cd) in soil samples from farmlands along highways in parts of Owerri. Soil samples were collected from cassava farms along three major roads with high traffic density and a rural road that served as control location, for possible heavy metals contamination due to vehicular emission. Standard laboratory procedures were adopted to determine the concentration of heavy metals using Atomic Absorption Spectrophotometer (AAS). Contamination factor (CF) and Pollution Load Index were mathematically calculated. The results revealed that the mean concentrations of metals in soil samples in mg/kg ranged from 3.00-6.31 for Cu; Pb, 0.09-4.00; Zn, 3.97-8.59; Ni, 0.001-0.96; and Cd, 0.31-0.79. These metals showed decrease in concentrations with increase in distance away from the highway. The values of contamination factor (CF) were low except for Cd and Pollution Load Index (PLI) for all soil studied showed no sign of pollution. There was no correlation between traffic density and concentration of heavy metal in soil except for Cd (Rs= 0.800). The overall results showed evidence of some heavy metal pollution on the soils with possible cumulative effect over time.

“…They can also migrate to surface and ground waters and spread in great distances, re-enter food chains and poison live organisms (Vosylienė et al 2010). Heavy metals can both migrate and accumulate within soil, often disturbing soil processes and sometimes causing soil degradation (Baltrėnas, Vaišis 2006;Poszyler-Adamska, Czerniak 2007). The migration and accumulation of heavy metals in soils depends on several environmental factors, such as meteorological conditions, the chemical and mineralogical composition of soil-forming rocks, the textural composition of the soil, soil solution pH, sorption, and the amount of the soil organic matter (Johnson et al 2011).…”

“…introduction ecological studies have shown significant exposure-response relationships for adverse pollution effects in association with particulate mass concentrations (Poszyler-Adamska, Czerniak 2007;staniūnas et al 2010). Particulate matter has been associated with pollution and fate in urban storm water (Valentukevičienė, ignatavičius 2011).…”

The main aim of this study was to characterize heavy metal compounds of sweep sand particles in the city of Vilnius (lithuania). These research results provide new insight into the distribution and variation of heavy metal compounds in sweep sand in the studied area. The results of this investigation reflect the level of heavy metal pollution during the winter season, thus can be used to judge the quality of storm water flowing from streets. The major heavy metals found to have accumulated were lead, nickel, zinc and copper. These research results are useful for conducting preliminary evaluations of possible heavy metal pollution in other similar cities within the european union. The general anthropogenic factor of three main types of land-use has the greatest influence on contamination of urban topsoil. in industrial sites, concentrations of key contaminants (Pb, Cu, Mn, ni) are significantly higher than in residential and public-residential areas. The present article discussed the significance of systematic sustainable evaluation as one of the most important activities associated with a sustainable approach. Consequently, to reduce a negative effect of salts on street environment, measures of environmentally sustainable development have to be undertaken.Keywords: heavy metals, deicing salts, sweep sand, sustainable development, valuation of environmental effects, environment and development.Reference to this paper should be made as follows: Kazlauskienė, A.; Valentukevičienė, M.; ignatavičius, G. 2013. sustainability assessment of heavy metals and road maintenance salts in sweep sand from roadside environment,
