“…In the wet period, Cd levels at all sites were nearly equal to or exceeded the SQGs except ERL. Heavy metals in soils and sediments are known to mobilize and increase availability during rainy seasons [52][53][54]. Although the concentrations of Cr at all sites were higher during the wet period compared to the dry period of the year 2019, none of the sites had Cr levels above the SQGs in both sampling periods.…”

This study investigated the levels of Pb, Hg, Cr, Cd, and As in water and sediments from the tributaries of the Mara River, Tanzania. Pollution risk of water and sediments was investigated using seven indices and five metals. During the dry period, the highest concentration of Pb, Hg, Cr, Cd, and As in sediments was 17.45 ± 1.22, 0.01, 1.56 ± 0.5, 1.3 ± 0.09, and 30.81 ± 0.02 mg/kg, respectively. During the wet period, the highest concentration of Pb, Hg, Cr, Cd, and As in sediments was 4.37 ± 0.28, 0.012, 2.58 ± 0.57, 2.25 ± 0.35, and 53 ± 0.02 mg/kg, respectively. For surface water, the respective highest concentrations of Pb, Hg, Cr, Cd, and As were 0.76 ± 0.09, 0.04, 0.68 ± 0.09, 0.74 ± 0.1, and 0.47 ± 0.06 mg/L for the dry period. The wet period max concentrations for Pb, Hg, Cr, Cd, and As in surface water were 0.56, 0.03, 0.55 ± 0.03, 0.48 ± 0.03, and 0.4 ± 0.03 mg/L, respectively. Principal component analysis results indicated dominant loadings for Pb and As in sediments during the dry period. Comparison of sediment concentrations with sediment quality guidelines revealed that As and Cd were enriched. Correlation coefficient results indicated that As had a strong negative correlation with the rest of the elements in sediments during the dry period. In the wet period, As had a significant correlation with Cd (r = 0.92, p < 0.01) in sediments. The analysis of environmental risks indicated significant enrichment of sediments with As and Cd. It is important to put in place relevant control mechanisms targeting metals in the studied tributaries, with a focus on As and Cd.

“…Thus, the carcinogenic risks for these three metals were lower than the threshold values range (10 -6 -10 -4 ), above which environmental and regulatory agencies consider the risk unacceptable, this signifies no cancer risk for natural use in Tehran city. Junhua et al collected surface dust samples from 14 different sites in 5 different function areas in Maha Sarakham and Thailand municipality (7). Function areas were classified as commercial, parking lot, residential, park, and traffic.…”

Background: The present study investigated the impact of land use on health risks (cancerous and non-cancerous) of heavy metals in soil along the Hemmat Highway of Tehran, Iran. Materials and Methods: A total of 28 soil samples were collected in August 2014 from the roadside soil of the Hemmat Highway. The collected samples were air-dried and digested, and then, analyzed for heavy metals using an atomic absorption spectrophotometer (AAS). Non-carcinogenic and carcinogenic health risks were calculated for different land uses (green space, residential area, under construction, and natural) along the Hemmat Highway. Results: The hazard index (HI) of Pb, Zn, Cd, Cr, and Ni was, respectively, 0.28, 0.19 × 10-2 , 0.032, 0.043, 0.006 for children, and was 0.037, 0.24 × 10-3 , 0.014, 0.012, 0.76 × 10-3 for adults. Carcinogenic risk of metals was analyzed for Cd, Cr, and Ni. The carcinogenic risk of Pb, Ni, Zn, and Cd was 0.144 × 10-7 , 0.427 × 10-6 , and 9.41 × 10-2 , respectively. Conclusions: The carcinogenic risk levels of the three studied metals were < 10-6 with higher values attributed to Cr. HIs for all metals were lower than their threshold values, indicating nil health hazards. The results of risk assessment showed that the highest risk value was related to ingestion of Pb.

Background: Human activities related to workshops in the cities contribute to the release of heavy metals into the environment, which pose serious risks to the environment and to human health. The aim of the present study was to evaluate the concentration of lead (Pb), iron (Fe), and manganese (Mn) in the pine trees and soil in various land uses of Birjand city, Iran. Methods: The sampling stations were randomly selected from different land uses including parks, streets, carwashes, car repair shops, and car smooth shops in Birjand city. The pine trees (skin and leaves) and soil samples were collected from 15 stations located at different and uses in 2017. To determine the concentration of heavy metals, atomic absorption spectrometer (Contr AA 700) was used. Results: It was revealed that the mean concentration of Pb, Fe and Mn in residential soil was 1.79, 419.39, and 30.76 mg/kg, respectively. Moreover, the Pb, Fe, and Mn concentration in pine skin and leaves was 0.63 – 0.18, 23.05–9.84, and 10.05–3.13 mg/kg, respectively. The geo-accumulation index (Igeo) mean of the study areas demonstrated a descending trend for Fe (16.31 mg/kg) <Mn (8.86 mg/kg) <Pb (0.41 mg/kg). Pb showed the highest transfer factor in the parks and streets followed by Mn and Fe. In the car repair and smooth shops, the highest transfer factor pertained to Pb and the lowest one pertained to Fe. The statistical analysis indicated that there was a significant difference in the Fe and Mn concentrations among various land uses (P < 0.05). Conclusion: According to the results, the soils of car repair and smooth shops as well as carwashes in Birjand are becoming polluted by Pb, Fe, and Mn. Although, it does not threaten the city ecosystem, but with passage of time, these measures will be accumulated due to the soil alkalinity and will reach critical levels.
