Implication

Randomized trial assesses microplastic contamination and water quality variations in the lower Ganga River, indicating significant environmental challenges.

Key Points

The study aims to assess the spatial variability of physicochemical properties and microplastic contamination in water and sediments of the Lower Ganga River.
12 sampling sites selected across four districts of West Bengal.
36 water and sediment samples collected in triplicate for analysis.
Spatial distribution patterns analyzed using IDW interpolation in ArcGIS.
Lowest WQI value recorded at Gournagar was 39.50, indicating poor water quality.
Microplastic analysis revealed fibrous particles at 45.5%, fragments at 45%, and spherules at 9.5%.
Highest concentrations of microplastics (30–38 particles per 100 g dry sediment) were found at Jorabagan and Fairley Ghat.
