“…In most studies, traffic emission was recognized as the most important factor that would lead to significant quantities of metals deposited in roadside soils, for example, in China (Chen et al 2010;Wei and Yang 2010;Lu et al 2012), Turkey (Guney et al 2010;Kadıoğlu et al 2010), Greece (Massas et al 2009), Pakistan (Karim et al 2015), and Nigeria (Azeez et al 2014). Some studies have focused on the concentrations of heavy metals in roadside soils derived from vehicular emissions and demonstrated their detrimental impacts on the surrounding environment (Khan et al 2011;Yan et al 2012;Vural 2013).…”

Purpose The overall objectives of this study were to examine the relationship between the concentrations of heavy metals such as Pb, Zn, Cu, and Cd in roadside soil derived from three different geological parent materials, Hawkesbury Sandstone, Wianamatta Shale, and Mittagong Formation and also to examine the influence of rainfall events on heavy metal concentrations in both the topsoil and the subsoil in all three soil types. In this paper, the focus is on lead and zinc. Materials and methods The results obtained from the samples taken from an initial transect were used to select the location of the study sites. Soil samples were collected using a stainless steel auger at distances of 1, 5, and 10 m from the edge of two major roads of similar traffic volumes bordering a suburban park. At each of five study sites, samples were collected at depths of 0-10 and 10-30 cm, three times pre-rainfall (after extended periods of no rain) and three times post-rainfall (after intensive rainfall periods). The modified aqua regia digestion method was applied for heavy metal concentrations measurement. To determine the temporal dynamics of trace elements in the soils, sequential extractions were applied to all the topsoil samples according to the modified three-step sequential extraction procedure. Results and discussion The corresponding concentrations of Pb and Zn were different for the soil derived from Hawkesbury Sandstone and Wianamatta Shale and also Mittagong Formation. The highest concentration of Pb was in the soil from Wianamatta Shale, 159.32 mg/kg and the highest concentration of Zn was in the soil from the Mittagong Formation, 254.12 mg/kg, all at a distance of 1 m from the roadside. From the sequential chemical extraction results, the rainfall substantially influenced the exchangeable fraction (F1) of Pb at a distance from the road of 1 m. A significant reduction of F1 was found for the soil derived from Mittagong Formation which also had the most significant reduction of total Zn concentration. Conclusions The interpretation of the results showed that there was a clear correlation between the concentration of Pb and Zn with the distance from the roadside and depth in all soil types. However, the results also showed that there are variable concentrations between the soil types. The heavy metal concentrations at the same distance for the three soil types are different. The rainfall events do influence the heavy metal concentration differently in both topsoil and subsoil of the three soil types at the same distance from the roadside.

Graphene oxide (GO) was covalently attached to glassy carbon (GC) electrode (GC-O-GO) for fabricating nanosensors to determine trace Pb 2+ and Cd 2+ using differential pulse anodic stripping voltammetry (DPASV). Surface characterization of the nanofilm-covered electrode was performed via electrochemical cyclic voltammetry (CV), transmission electron microscopy (TEM), atomic force microscopy (AFM), and X-ray photoelectron spectroscopy (XPS) techniques. Surface pKa of the GO covalent attached GC (GC-O-GO) was calculated via CV. Under optimal conditions, a linear response was found for Pb 2+ and Cd 2+ in the range from 1×10 −8 to 1×10 −12 M. The limit of detections (LODs) of Pb 2+ and Cd 2+ were 0.25 pM and 0.28 pM, respectively. The method shows good reproducibility, and stability was successfully applied to measure Pb 2+ and Cd 2+ levels in rice, soya, milk, and tap water samples, with good agreement with those obtained by the standard inductively coupled plasma optical emission spectrometry (ICP-OES) method. The method was evaluated by application with the simultaneous determination of the ions in food samples (n=6) using the standard addition method. The recoveries of the Pb 2+ and Cd 2+ were up to 98 %.

“…There are adverse effects of heavy metal particulate on respiration, especially on sick and elderly people as well as children living in contaminated areas. Some heavy metal pollutants may also serve as immunotoxins, resulting in increased vulnerability to infection (Sorvari et al, 2017;Kadioglu et al, 2010). Health effects related to urban air pollution have primarily occurred in megacities due to high concentrations of atmospheric air pollutants (Brook et al, 2017;Yurdakul et al, 2019;Tepe and Doğan, 2019).…”

“…As a result of industrial activities, air pollution has now arisen in developed countries and the quantity of emission sources such as improper vehicles has also increased (Ghorani-Azam et al, 2016). Air quality in Ankara as the capital and high populated city in Turkey relied on varied natural sources, such as man-made pollution (for example traffic, domestic heating, industrial and commercial activities), topographic factors, and meteorological, and atmospheric conditions (Kadioglu et al, 2010;Bari and Kindzierski, 2015;Sari et al, 2019). In the last two decades, Ankara has faced severe ambient air pollution, particularly air pollutants criteria (particulate matter (PM10 and PM2.5), Carbon monoxide (CO), Nitrogen Dioxide (NO2), Nitrogen Oxides (NOX), and sulfur dioxide (SO2), due to the unsustainable growth of industrialization and urbanization as well as influenced by high traffic activities (Genc et al, 2010;Njoku et al, 2016;Baran 2021).…”

The aim of this study is to examine levels, temporal changes and interactions of major air pollutants with meteorological variables in Ankara, Turkey. The level of air pollutants namely PM10, PM2.5, SO2, NO, NO2, NOX, O3, CO was evaluated monthly, seasonally, and annually during 2019. The statistical relationship between air pollutants and ambient temperature, relative humidity and air pressure was examined and discussed. The pollutants concentrations started to rise in the morning and evening hours (excluding O3) when the traffic was at its peak and was at the highest level between 10:00 -14:00 and 22:00-02:00. It was seen at the lowest values (excluding O3) during daylight hours. A strong positive correlation was reported between PM10 and both PM2.5 and CO. Also, it was positive between NO and CO and NOX. On the other hand, negative correlation was reported between O3 and all other parameters. Moreover, paired comparisons of the selected parameters during the seasons were investigated. A statistically significant difference was found between different paired parameters namely CO/NOX, SO2/NOX and PM2.5/PM10. The results revealed that the changes in the meteorological parameters during the mentioned seasons significantly impact the behavior of air pollutant parameters.
