“…Although heavy metals are naturally present in soil, there is metal pollution due to local sources, such as power plants and iron (14,15), steel and chemical industries (16), agriculture activities, including irrigation with polluted waters (17), sewage sludge and fertilizers (18), contaminated manure and pesticide containing heavy metals (19), waste incineration (20), combustion of fossil fuels, and road traffic (21,22). Long-range transport of atmospheric pollutants adds to the contamination of metals in the nat-ural environment (23).…”

Background: Currently there is much concern in the field of soil contamination with heavy metals due to rapid urbanization. Soil contamination significantly reduces environmental quality and affects human health.Objectives: This study was performed to determine the level of As, Cd, Co, Cr, Ni, Pb, and Zn in the soils of Babol city in Mazandaran province and to evaluate the pollution indices of heavy metals. Methods:Concentrations of heavy metals in 50 samples of surface soils (5 to 15 cm) in urban and rural areas of Babol city were measured using inductively coupled plasma optical emission spectrometry (ICP-OES). In this study, various indices including contamination factor (Cfi), degree of contamination (Cdeg), Nemerow integrated pollution index (NIPI) and the potential ecological risk (ERi) with heavy metals were assessed.Results: Mean content of As, Pb, Cd, Zn, Cr, Ni, and Co in soil samples of different locations were 6.90 ± 2.60, 31 ± 5.70, 0.32 ± 0.1, 82.80 ± 15, 32.40 ± 8.30, 34.50 ± 7.50, and 22.6 ± 6 mg/kg, respectively. The average content of these metals is ranked in the following descending order: Zn > Cr > Ni > Pb > Co > As > Cd. The order of contribution of the potential ecological risk by metals was Cd (51.91%) > As (23.75) > Pb (7.61%) > Cr (5.57%) > Co (5.24%) > Zn (3.04%) > NI (2.88%). Conclusions:This study indicated that the risk assessments of the soil samples with heavy metals in the studied locations are categorized from low to moderate degree of contamination.

“…Rapid worldwide urban and economic growth has a negative impact on the environment, especially in terrestrial and aquatic ecosystems, which are the ultimate receiving sink for untreated industrial and agricultural effluents, and domestic sewage discharges (1,2). Therefore, the spread of pollutants, particularly of toxic metals, to the aquatic ecosystems is increasingly worrying (3).…”

Background and Purpose: The heavy metal pollution and its fractionations in the surface sediments of Darreh-Morad Beyg River, Hamedan City were monitored for Cd, Cr, Cu, Fe, Ni, Pb, and Zn in 2014. Materials and Methods: Totally 30 surface sediment samples were taken from 10 stations with three replicates. The samples subjected to bulk digestion and chemical partitioning. The concentrations of heavy metals in sediment were determined by ICP-OES. I-geo, EF, CF, and PLI were also used to assess the sediment contamination. Results:The results of the present study showed that the proportions of residual fraction for Cu, Ni, Pb, Cd and especially Cr (93.61%) were relatively high, which implied their lower pollution risks due to low mobility characterization, while Zn was mainly associated with the anthropogenic portion of the existing pollution which meant an increase in mobility for this element. Also, on the basis of the mean, the I-geo values of metals were found in the following order: Cr>Cu>Zn>Ni>Pb>Fe>Cd. At the same time, the average EF of metals in the sediment samples was in the order of Cr>Cu>Zn>Ni>Pb>Fe>Cd. According to the calculated PLI, the pollution class of heavy metals in sediments from the Darreh-Morad Beyg River was between 1 and 2, indicating a moderately polluted degree. Conclusion: Regarding the high Zn concentrations in sediments, it is likely that this element is a major hazard for the aquatic environment since it is mainly found in the anthropogenic portion. Also, Cu, Ni, Pb, Cd, and Cr are present in the greatest percentages in the residual fraction, which implies that these metals are strongly linked to the sediments.

“…In particular, heavy metals released from various sources, such as petrochemical, paper, energy, transportation and fertilizer industries, can cause damage to the ecological balance by following the path of dry and wet deposition to the surface and surface waters, and then mixed up in groundwater [2][3][4][5][6][7][8]. Generally, soil is able to neutralize the high level elements in it and so prevent aquatic organisms from the toxic effects of these elements.…”

Abstract. Many cities, especially larger metropolises, parks are very important recreational areas where people usually have closer contact with flora. Therefore, the pollution level in the parks can have a greater effect on human health. Heavy metals are ubiquitous with the environment, as a result of both natural and anthropogenic activities, and humans are exposed to them through various pathways. Essentially, these areas are assumed to be less exposed to routine contaminants, but especially in metropolises, this assumption could prove false considering these areas are stuck within the confines of a city full of pollutant activity such as intense traffic. In this study; the relationships between heavy metal pollution levels (Cd, Cr, Cu, Ni, Pb, Zn) and the pH and electrical conductivity (EC) of soil samples were investigated from the parks on the Asian side of Istanbul. For this purpose, the most frequently visited 16 parks were selected as sampling sites. In the second part of the study, linear correlation is used for the data analysis.
