Summary
This summary is machine-generated.Potentially toxic element (PTE) pollution in Jaipur
Area Of Science
- Environmental Science
- Soil Science
- Geochemistry
Background
- Rapid urbanization and industrialization in Jaipur, India, pose risks to surrounding agricultural lands.
- Semiarid regions are particularly vulnerable to soil contamination due to limited water for dilution and flushing.
Purpose Of The Study
- To assess potentially toxic element (PTE) pollution in agricultural soils near Jaipur.
- To determine the distribution and ecological risk of PTEs in the study area.
- To identify the sources of PTE contamination.
Main Methods
- Agricultural soil samples were collected near an industrial region.
- Concentrations of PTEs and soil parameters (pH, N, C, P, K) were analyzed.
- Soil pollution indices (Igeo, CF, ERI) and BCR extraction were employed.
- Multivariate analysis and Pearson correlation were used for source apportionment.
Main Results
- PTE concentrations followed the order: Mn > Pb > Ni > Cr > Cu > Cd.
- Geochemical accumulation index, contamination factor, and ecological risk index indicated moderate to high pollution.
- Cadmium (Cd) and Lead (Pb) were identified as major contributors to pollution and ecological harm.
- Cd and Pb showed common source apportionment, suggesting industrial origin.
Conclusions
- Soils in the agricultural outskirts of Jaipur are significantly polluted with PTEs, particularly Cd and Pb.
- The contamination poses ecological risks requiring urgent attention and policy interventions.
- Understanding PTE fractions and sources is crucial for effective soil remediation strategies.
