Abstract Heavy metal contamination in soil media presents significant environmental and health challenges. While concerns over these risks continue to grow, there remains a gap the use of advanced probabilistic methods geospatial analyses accurately assess levels impacts. This study evaluates associated with eight heavy metals such as iron (Fe), arsenic (As), zinc (Zn), copper (Cu), nickel (Ni), chromium (Cr), lead (Pb), cadmium (Cd) urban soils. Surface samples were analyzed using ICP-OES after tri-acid digestion, indices Geoaccumulation Index (Igeo), Contamination Factor (CF), Pollution Load (PLI), Hazard Quotient (HQ), (HI), Carcinogenic Risk (CR) used impacts across age groups via oral ingestion dermal contact. Results show concentrations follow order Ni > Zn Pb Cu Cr As Cd, more than 60% demonstrating pollution levels. HQ values exceeded 1 most samples, indicating substantial non-carcinogenic risks, while CR assessments revealed 33% population faces high from exposure. Hotspots identified analysis Monte Carlo simulations highlight elevated carcinogenic emphasizing need for targeted remediation, especially children, focus on contamination.

This environmental assessment focuses on the coastal sediments of Al-Khafji area in Saudi Arabian Gulf, with an analysis human health risks posed by lead (Pb) and cadmium (Cd) contamination. Single integrated indices were used to detect contamination evaluate these metals' non-carcinogenic carcinogenic impacts adults children through ingestion, dermal contact, inhalation pathways. Sediment quality guidelines indicated absence significant levels. The moderate observed scattered samples did not imply adverse biological effects due presence two metals sediments. average values chronic daily intake (CDI) for both Pb Cd higher than across all three pathways, ratios 9.4, 4.7, 4.7 folds, respectively. hazard index (HI) below 1, confirming that are considered acceptable safe terms potentially toxic elements (PTEs). lifetime cancer risk (LCR) compared adults, 9.3 9.4 However, detected LCR levels do represent a potential hazard. Nevertheless, regular monitoring program aimed at detecting early signals depletion is recommended.

This research examined heavy metals distribution and potential environmental impact in seven locations along the Bhavnagar coast Gujarat, India. The study used several analyses, including hierarchical cluster analysis (HCA), principal component (PCA), correlation to investigate harmful present area. To evaluate possible risk of Cd, Pb, Cr, Zn, Co, Cu, Ni, Mn, Fe marine environment, pollution indices such as contamination factors (Cf), enrichment factor (Ef), geo-accumulation index (Igeo), ecological (Er), (RI) sediment quality guidelines (SQGs) applied. Based on results, mean concentration was ranked following order (mg/kg): (561.4) > Mn (58.9) Cr (42) Zn (12.5) Pb (8.2) Ni (7) Cu (5.2) Co (2.7) Cd (.3). Compared pre-monsoon post-monsoon seasons, results showed a diluting metal concentrations during monsoon season. spatial indicated that geogenic source anthropogenic were primary contributors studied region. Principal suggests may have come from shipbreaking activities, municipal discharge industrial operations. Cf, Igeo, Ef demonstrated no moderate pollution, with maximum contribution coastal poses minimal for all investigated. Shipbreaking, urban runoff, salt-marine, agricultural runoff release toxic into environment. In conclusion, information obtained this geochemical characterization could be valuable policymakers stakeholders developing effective management measures region, Gulf Khambhat,

Abstract Dermal contact, ingestion and inhalation of heavy metal poses significant health risk in human subjects. The exposure could be via potable water, soil or air. current experiment design focuses on media exposure. Advanced probabilistic geospatial methods are used this study which evaluates contamination levels risks associated with iron (Fe), arsenic (As), zinc (Zn), copper (Cu), nickel (Ni), chromium (Cr), lead (Pb), cadmium (Cd) samples. samples were collected analysed using ICP-OES after tri-acid digestion, indices such as Geoaccumulation Index (Igeo), Contamination Factor (CF), Pollution Load (PLI), Hazard Quotient (HQ), (HI), Carcinogenic Risk (CR) to assess environmental impacts across the age groups oral ingestion, dermal contact. indicates concentrations follow order Ni > Zn Pb Cu Cr As Cd, more than 60% demonstrating pollution levels. computational method revealed substantial non carcinogenic (HQ 1) (33%) population related Geospatial analysis Monte Carlo simulations helped identifying hotspots tropical coastal area emphasizing need for targeted remediation focusing Pb.
