“…Several industries release Cd to the environment. However, the production of batteries, dyes, and alloys were reported as dominant sources (Hanfi et al 2020). The mean Cd concentrations in the current study showed comparable mean concentration in Shitolokkha River, Bangladesh and Zohreh River, Iran (Ahmadee et al 2016).…”

“…Pb in the urban environment is released from both natural and manmade sources. Nevertheless, it was reported that the major manmade sources are industrial activities such as mining, manufacturing, and fossil fuel burning, in addition to different agricultural and domestic applications as well as traffic emissions and weathering of materials (Hanfi et al 2020).…”

Louhajang River, Bangladesh, crosses Tangail, which is a densely industrialized and urbanized city. Louhajang River is an essential water source for domestic, irrigation, and urbanization purposes. This study reports the levels of pH, electrical conductivity (EC), and some toxic heavy metals in 40 water samples collected during summer and winter seasons from Louhajang River. The levels were found to be in the ranges of pH 6.22-7.43 and EC 345-798 mS/cm, Cr 0.18-13.2, Ni 0.02-19.04, Cu 0.96-15.92, As 2.18-12.51, Cd 0.02-2.42, and Pb 0.49-15.74 µg/L. The winter season reported higher levels of the examined parameters than the summer season with significant variation (p < 0.05) for all parameters, with the exception of Cd. The metal contents were assessed against local and international standards for drinking, irrigation and aquatic life purposes where different trends were observed. The heavy metal evaluation index (HEI) and the ecological risk index (ERI) reported low to moderate risks. The spatial distribution of metal contents assigned hot spots in some sites along the riverbed, which were attributed to specific manmade sources. The health risk assessment for three population categories, i.e., adult male, adult female, and children, were examined in terms of hazard index (HI) and total cancer risk (TCR) for oral and dermal pathways during both seasons. Cr and Cd recorded HI more than unit in all cases, indicating possible non-cancer risk. TCR values of As for the three examined population categories during both seasons were > 1.0×10-6, indicating possible cancer risk, while that of Pb were < 1.0×10-6. For Ni, about 10-25% of the sampled sites recorded TCR > 1.0×10-6.

“…Urban soils are inside or nearby cities, i.e., in urban and suburban areas that are significantly and persistently disrupted by human activity [3]. They include: (a) soils consisting of a mixture of materials of different origins, with inorganic or organic compositions, and from agricultural or forest areas, which are largely transformed by human intervention [4]; (b) soils in parks and green gardens that offer different compositions, uses, and management of agricultural land [5,6]; and (c) soils or mixtures resulting from various construction or metallurgical activities within cities [7].…”

Level of Contamination Assessment of Potentially Toxic Elements in the Urban Soils of Volos City (Central Greece)

et al. 2021

A three-year study, designed to record the level of potentially toxic elements within the urban complex in the city of Volos, Greece, was carried out between 2018 and 2020. For the needs of the aforementioned study, 62 surface (0–15 cm) soil samples were collected each year (i.e., 186 samples in total) from an urban area of 3.65 km2, and the average value of pseudo-total metal concentration was measured. Soil pollution indices, such as the contamination factor (CF) and the geo-accumulation index (Igeo), were estimated regarding each of the metals of interest. The respective thematic maps were constructed, and the spatial variability of the contamination degree was displayed. Higher values of the CF and Igeo were obtained near the heavy traffic roads and beside the railway station, the bus stations, and the commercial port. The maps based on the pollution indices, along with the database that was constructed using the appropriate mathematical tools of geostatistical analysis, may be a useful tool for monitoring, prediction, and continuous verification of contamination in the urban soils of Volos city.

“…Urban sediments are leaves, debris, and organic and inorganic materials present in the urban environment [1]. Urban sediments occur from natural sources; soil and rock weathering and atmospheric deposition [2][3][4][5][6][7], as well as anthropogenic sources; these include emissions from agriculture, municipal levels, road traffic, industrial and residential areas, and domestic emissions [8][9][10][11]. Sediments collect on various surfaces, such as roofs, roads, and driveways, during dry weather, in river bed and sewage systems, and in receiving reservoirs.…”

Urban soil and urban surface deposited sediments (USDS) are a large basin for receiving heavy metal contaminants from natural resources and anthropogenic activities. The present study is a review carried out the previous studies determine metal impacts in the urban environment on potential health hazards. The environmental risk index (E r) values follow a trend for different urban soils and USDS: the high E r value in the period 1980-1990 in urban areas is due to Cd 7200, followed by Pb 662, Cu 42, Zn 23, and Ni 6. The health risk assessment varied with the type of heavy metal, the time of year, the level of contamination, environmental pollution, and the human age. No significant risk was identified for adults and children in different urban areas.
