Comparative Studies of Physico-Chemical Properties of the Roadside Soil at Morena (M.P.)

Abstract

The quality of roadside soil along the NH3 highway of high traffic density at Morena-M.P. was studied during 2010-11 at 12 different locations. The roadside soil was found to be highly contaminated. This is evident from the modification of the soil pH, Electrical conductance, Water holding capacity and other Physico-chemical properties when compared to natural soil. The presence of heavy metals like Zn, Cu, Mn, Fe in the roadside soil was also considerable.

Assessment of Heavy Metal Content in Soils Adjacent to the DK16-Route in Olsztyn (North-Eastern Poland)

“…Higher soil salinity along Sielska Street was significantly correlated with the content of Cd (r = 0.59**), Cr (r = 0.36**), Cu (r = 0.67**), Pb (r = 0.55**) and Zn (r = 0.67**) (Table 2), whereas the soil reaction was significantly correlated with the soil content of Cd (r = 0.45**), Co (r = 0.36**), Ni (r = 0.45**), Cu (r = 0.33**), Pb (r = 0.42**) and Mn (r = 0.34**) (Table 3). The soil reaction noted in our research (Table 1) in general agreed with the data reported by other authors [7,21], or was slightly higher [12]. High soil reaction could be a barrier to the mobility of heavy metals and their translocation to the soil solution [21].…”

“…This is certainly connected with its position on the outer bend of the road as well as the bicycle lane and footpath situated there. Higher salinity of soils closest to a road has been observed by other researchers [3,7], and the reason is the application of sodium, calcium or magnesium chlorides in winter to minimise the risk of skidding by vehicles [32][33]. Values of the EC which are approximately the same as in our research have been observed in soils samples near streets of Wrocław [12].…”

“…The development of transportation infrastructure, especially in urbanised areas, where constant population growth is observed, exerts pressure on the natural environment, including air, water and soils [2][3][4][5], as well as on human health [2,[4][5]. Large quantities of organic pollutants [6], as well as heavy metals [5], mainly Pb, Cd, Zn, Cu, Mn and Fe [7], detected in areas along roads and streets implicate the persistence of these substances in the natural environment and their tendency to bioaccumulate [5][6]. Because of toxicity and negative influence of heavy metals on health and people [2,[4][5]8], soil contamination with these elements is still considered as an important environmental problem [2][3][4][5]8].…”

“…Following a number of measures taken to reduce emissions (e.g. the ban on lead petrol), the unit emission of pollutants from motor vehicles has decreased, which nevertheless has not decreased substantially the input of pollutants generated by road transportation [2], because the number of vehicles has increased [2,7]. The highest concentrations of pollutants caused by the emission of exhaust fumes from cars occur near the ground (Adamiec et al 2016) [9].…”

Assessment of the Heavy Metal Contamination of Roadside Soils Alongside Buddha Nullah, Ludhiana, (Punjab) India

“…It is well established that soil physico-chemical characterization plays a key role in exploring the composition of soil and evaluating soil pollution [26,27]. Many studies across the world have been conducted to explore the physico-chemical characteristics of roadside soil in different regions [10,[28][29][30][31][32].…”
