Implication

Randomized trial assesses heavy metals contamination and health risks in the Rapti River Basin, highlighting urgent monitoring needs.

Key Points

The aim is to assess physicochemical parameters and heavy metal contamination in the Rapti River Basin and evaluate associated ecological and human health risks.
Water and sediment samples (N=30) collected across three seasons for heavy metals and physicochemical analysis.
Risk assessments conducted using Pollution Load Index (PLI) and Potential Ecological Risk Index (PERI).
Principal Component Analysis (PCA) used for source apportionment of heavy metals.
Lead exceeded permissible limits in water, and non-carcinogenic risk was 'low' in water but 'high' in sediment.
Monsoonal flow significantly altered sediment geochemistry, resulting in increased pollution levels.
Carcinogenic risk for children exceeded safe thresholds in water during monsoon.
