“…Cd intake by the plants can be affected by absorption order of metal ions. Cd uptake changes in the order: Astragalus echinatus M. > Malva neglecta W. > Viola occulta L. > Senecio vulgaris L. In site 1, 2 and 5, the Cd pollution was caused by atmospheric conditions (Zhang et al, 2016). Pb contamination also increases near the tire factory as expected.…”

“…The plants (Viola occulta L., Malva neglecta W., Astragalus echinatus M., Senecio vulgaris L.) were collected in April before the rain season. The plant species were chosen by two main factors: (1) how representative they were among those plants growing naturally along the roadside of Kirsehir-Mucur highway, and (2) whether they were dominant plant species as indicators of regional environmental conditions (Zhang et al, 2016). The collected plant samples were dried in oven at 105°C.…”

“…For this, the most appropriate method is path analysis (Karadavut, 2009). In the study by Zhang et al (2016) about determination of roadside pollution because of trafficking in the plants of Kobresia pygmaea, Stipa purpurea and Kalidium slenderbranch, found that some plants uptake Cd from soil some others accumulate from atmospheric conditions. In another study by De Silva et al (2016), Cd and Pb accumulation in roadside soil were recorded as Cd (0.06-0.59 mg/kg) and Pb (16-144 mg/kg).…”

This study is about spectroscopic determination of cadmium and lead amount in some plants located near the highway between Kirsehir Center and Mucur districts. Collected plant samples were dried in an oven and left in an acid solution for getting soluble ions into the solution. After preparing reference solutions for atomic absorption spectrometer, the amount of lead in the samples were detected. After preparing reference solutions for UV-Vis spectrophotometer, the amount of cadmium in the samples were detected. The results show that there is a correlation between being close to contamination sites and the lead content in the samples. Correlation analysis showed that the positive and significant relationships were determined between pH level and cadmium concentration inside the plants (r=0.864), and lead concentration inside the plants (r=0.667).

“…Studies have found that Pb-containing gasoline combustion can increase the soil content of Pb (Sun et al, 2010;Zhang et al, 2018). Similarly, the combustion of crude oil can also release trace amounts of Cd that were present in the crude oil mixture (Manno et al, 2006;Zhang et al, 2016). Zinc may have been derived from refinery and petrochemical units as well as lubricating oils, tires, mechanical abrasion of vehicles (Zhuo et al, 2020).…”

The presence of heavy metal(loid)s in soils from anthropogenic sources such as activities related to fossil fuel processing area could pose serious threat to the ecosystem and human health. However, risk factors depend on the source, distribution and human interaction with these contaminants and therefore case specific study is needed. In this study, using a geological information system (GIS) and 63 surface soil samples, we fully assessed 190 km2 area of a developing gas region in southern Iran. Mean concentration of manganese (Mn), zinc (Zn), copper (Cu), lead (Pb), total chromium (Cr), cobalt (Co), arsenic (As) and Cadmium (Cd) was 341.24, 129.40, 32.90, 26.85, 16.56, 7.52, 0.67 and 0.63 mg kg− 1, respectively, while As, Pb, Zn and Cd surpassed the local background level. Moreover, soil pollution was also assessed by the contamination factor (CF), geoaccumulation index (Igeo) and ecological risk factor (Er). Accordingly, these soils were classified as moderate to heavily polluted with As and Cd and un-polluted to slightly polluted by Cu, Zn, Pb, Mn, Cr and Co. The GIS and soil collection point tracing showed that the natural gas processing and residential activities were both significant pollution sources where ingestion was the main contributor to heavy metal(loid)s uptake. Overall, the hazardous index for noncarcinogenic health impact was < 1 indicating no risk; however, children were at greater risk than the adult. Total carcinogenic risk (TCR) index from As exceeded the maximum tolerable level (1.0E-04) for children and adults. Chromium Co, Cd and Pb exposure were within the acceptable limit in the adult group (TCR < 1.0E-06), but the Pb and Cr health-hazardous indices were higher than guideline value indicating the potential of cancer risk in children. Therefore, remedial actions are required to eliminate or reduce the toxicity of As, Cr and Pb attributed to the impacted soil.

“…Environmental pollutants from traffic infrastructure are an important subject in ecological and environmental sciences, due to their toxic effects on the biosphere [1,2,3]. It is generally accepted that highway transportation activities such as the combustion of liquid fuels, vehicular component abrasion and the weathering of pavement materials can release fine particles containing Zn, Pb, Cd, Cu and Cr [4,5,6,7].…”

Transportation activities such as fuel consumption, vehicle wear and road deicing can detrimentally affect the groundwater quality of fragile roadside wetland environments including. Nineteen parameters (Cu, Pb, Zn, Cd, Cr, Ni, Hg, As, pH, TDS, Ca2+, Mg2+, Na+, K+, SO42−, Cl−, HCO3−, NO3− and F−) were determined in groundwater samples from turfy swamps impacted by highway traffic from Jiangyuan (JY), Longquan (LQ), and Huangsongdian (HSD). Our results indicate that the metals Cu, Pb, Zn, Cr, Cd, the ions Na+, K+ and Cl− in groundwater were negatively affected by highway transportation, and the maximum affected distance of these pollutants varied from 15 to 100 m. The content of most of these pollutants in roadside groundwater decreased exponentially with the distance from the highway, as did the heavy metal pollution index HPI and Cd. The values of HPI and Cd in these three sites ranged from 46.8 to 78.4 and −4.9 to −2.9, respectively. The low pollution levels of heavy metals are related to the strong adsorption capacity of turfy soil towards metals. In any case, road transport activities increased the Cu, Pb, Zn, Cr, Cd, Na+, K+ and Cl− content in roadside groundwater in turfy swamp. With the increase of highway operation time, it will inevitably have a great influence on the groundwater quality of these wetlands. Therefore, the long-term monitoring is necessary to protect the sustainable development of turfy swamp.
