“…Zinc pollution in roadside soils was caused by traffic-related activities, such as vehicular emissions and the weathering of crash barriers [67,75,76]. Similarly, variations in the contents of heavy metals in the roadside soils were also reported by various authors around the world [77][78][79][80][81][82]. 1.…”

The present study was carried out to determine the physico-chemical characteristics and heavy metal contents in roadside soil samples collected during 2 sampling periods (September 2018 and April 2019) from 8 different roadside sites lying parallel to the Buddha Nullah, an old rivulet, flowing through Ludhiana, (Punjab) India. The contents (mg/kg) of seven metals (cadmium, chromium, cobalt, copper, lead, nickel and zinc) were estimated using a flame atomic absorption spectrophotometer. Among the metals analyzed, the contents of Cd, Co, Cu, Pb and Zn were found above the permissible limits. The results of the index of geoaccumulation (Igeo), contamination factor (CF), contamination degree (Cdeg), modified contamination degree (mCdeg), the Nemerow pollution index (PI) and pollution load index (PLI) indicate a moderate to high heavy metal contamination of the analyzed soil samples. The results of the potential ecological risk factor (ERi) and potential ecological risk index (RI) indicate a low to moderate risk of heavy metals in the studied soil samples. The Pearson correlation analysis revealed that most of the variables exhibited a statistically significant correlation with one or more variables during the two samplings. Multivariate analysis demonstrates that contents of heavy metals in the study area are influenced by anthropogenic and geogenic factors.

The present study in the Peenya Industrial Area in Bengaluru, India, carried out to assess the level of heavy metal contamination in the industrial area's soil and groundwater. The study also discusses the potential health risks that inhabitants would suffer from consuming contaminated groundwater. In 116 bore well water samples collected before and throughout the monsoon season, heavy metals including cadmium, chromium, copper, zinc, arsenic, mercury, lead, nickel, and aluminium were examined. Heavy metals concentration (mg/kg) was analysed for 36 soil samples collected in the research area and for heavy metals like chromium, nickel, copper, zinc, arsenic and cadmium. In the current study, the heavy metal pollution index (HPI), hazard index (HQ (ing) ) and cancer risk factor (CR) were calculated to assess the potential health risk. The HPI value inside the Peenya industrial area exceeded the critical pollution index value of 100. The hazard index (HQ (ing) ) via oral ingestion was found to be > 1.00 in Cr, Hg and As during both seasons, indicating maximum health impacts in the inhabitants of the study area. Cancer index values were > 10 -4 in Cr, Ni, Cd, and Pb in the research area, posing cancer risk in people of all ages, from children to adults. Environmental and human health are both put at risk in a polluted region. To assess soil contamination, the following indices were utilized: geoaccumulation (I geo ), single contamination index (PI), and pollution load index (PLI).Keywords: heavy metals (HM), hazard index (HQ (ing) ), cancer risk (CR), heavy metal pollution index (HPI), geoaccumulation (I geo ) index, single pollution index (PI), pollution load index (PLI).

“…This form of comparison exposes heavy metal correlations in several spatial dimensions and evaluates each metals relative importance. If the elements are more than what was prescribed or if changes were made to the natural environment, then the soil is considered to be contaminated 26 , 27 . Various researches have been conducted in the past few years on heavy metals pollution, source area, a pattern of dispersion, amount of pollution, and related concerns to human health in various regions around the world 28 – 30 .…”

Soils are usually the interface between human activity and environmental components that must be conserved and protected. As a result of rising industrialization and urbanization, activities such as exploration and extraction operations lead to the release of heavy metals into the environment. This study presents distribution of six heavy metals (As, Cr, Cu, Ni, Pb and Zn) in 139 top soil samples collected in and around oil and natural gas drilling sites at a sampling density of 1 site/12 km2. The results indicated the concentration ranged from 0.1 to 16 mg/kg for As, 3–707 mg/kg for Cr, 7–2324 mg/kg for Cu, 14–234 mg/kg for Ni, 9–1664 mg/kg for Pb, and 60–962 mg/kg for Zn. The contamination of soil was estimated on the basis of Index of geo accumulation (Igeo), enrichment factor (Ef), and contamination factor (Cf). Further, spatial distribution pattern maps indicated that the pollution levels for Cu, Cr, Zn, and Ni were higher around drilling sites of the study area relative to other regions. Using exposure factors for the local population and references from the USEPA’s integrated database, potential ecological risk indices (PERI) and health risk assessments were made. The hazard index (HI) values of Pb (in adults) and Cr, Pb (in children) exceeded the recommended limit of HI = 1, indicating the non-carcinogenic risks. Total carcinogenic risk (TCR) calculations revealed Cr (in adults) and As, Cr (in children) levels in soils exceeded the threshold value of 1.0E − 04, indicating significant carcinogenic risk due to high metal concentrations in the study area. These results may assist in determining the soil’s present state and its effect due to extraction strategies used during drilling process and initiate few remedial techniques, particularly for proper management strategies in farming activities to decrease point and non-point source of contamination.
