Supplementary file 1_Pollution characteristics, receptor model-based source apportionment,

A study quantifying nine Potentially Toxic Elements (Cr, Co, Ni, Cu, Zn, As, Cd, Hg, Pb) in water and sediment from India's Godavari River. The dataset includes 17 samples collected along a 1,465 km stretch, analyzed using ICP-MS, with results from receptor modeling and health risk assessments. The research was authored by Anisha Ganguly and published on figshare in April 2026.

Use Cases

• Identify pollution sources (e.g., lithogenic/mining, urban/traffic, agricultural) based on the receptor modeling results for Cr, Ni, Co, Cu, Zn, Pb, and As.
• Assess ecological risk for aquatic systems based on the reported Risk Quotient values for Ni and Zn and the Potential Ecological Risk Index.
• Evaluate human health exposure, particularly for children, based on the reported Hazard Index and primary risk drivers (Pb, As, Cr).
• Compare contamination levels against regulatory thresholds (e.g., WHO limits, Threshold Effect Levels) for elements like Cd, Cr, and Ni.
• Analyze spatial pollution trends along the urban-industrial corridor of Maharashtra based on the sample collection along the river's mainstem.

Strengths

• Includes results from two receptor modeling techniques (PMF and APCS-MLR) for source identification, with PMF showing a mean r² of 0.87.
• Provides integrated ecological and human health risk assessments, quantifying a 3.4-fold higher exposure for children compared to adults.
• Contains measurements for nine Potentially Toxic Elements in both water (µg/L) and sediment (mg/kg) matrices from 17 sampling points.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 89.9 KB file size suggests the dataset is a supplementary document, likely containing summary results rather than raw sample-level data.
