Insights into the seasonal variation, distribution, composition and dynamics of microplastics in the Ganga River ecosystem of Varanasi City, Uttar Pradesh, India
Researchers measured microplastic pollution in the Ganga River in Varanasi, India, and found contamination in both water and sediment samples across all seasons. Concentrations were higher after the monsoon season, with common plastics like polyethylene terephthalate, polyester, and PVC dominating the samples. Since the Ganga is used for drinking water, bathing, and agriculture by millions of people, this contamination raises direct concerns about human exposure to microplastics.

Sources and Factors Influencing Microplastic Concentration during Monsoon Season in Ganga River, Bihar, India
Researchers investigated sources and factors influencing microplastic concentrations in the Ganga River in Bihar, India during the monsoon season, examining how untreated residential and industrial waste discharge and traffic-related runoff affect plastic particle loads in one of the world's most biodiverse river systems. The study found elevated microplastic concentrations during monsoon flows, with urbanization and inadequate waste management identified as key drivers of microplastic inputs to the river.
Seasonal Dynamics of Microplastic Pollution in the River Ganga: A Case Study from Bihar
Researchers sampled microplastics at three locations along the Ganga River in Bihar, India, comparing concentrations before and after the monsoon season. Pre-monsoon levels averaged 1,045 particles per sample versus 624 post-monsoon, with higher dry-season concentrations attributed to reduced river flow and concentrated human activity near the riverbanks.
A comprehensive assessment of macro and microplastics from Rivers Ganga and Yamuna: Unveiling the seasonal, spatial and risk factors
This study provides the first comprehensive look at plastic pollution in India's Ganga and Yamuna rivers, finding microplastics in surface water, deeper water, and sediments at all sampling locations. Contamination was higher during the wet season, and some of the polymers found are classified as hazardous. The millions of people living in the Indo-Gangetic Plain may be at risk from both direct water contact and indirect exposure through the food chain.
The abundance and characteristics of microplastics in surface water in the transboundary Ganges River
Researchers conducted the first investigation of microplastic abundance along a 2,575-kilometer stretch of the Ganges River across pre- and post-monsoon seasons. The study found that fibers comprised 91% of microplastics, with higher concentrations before the monsoon, and estimates that the combined Ganges-Brahmaputra-Meghna river system could release 1 to 3 billion microplastic particles into the Bay of Bengal every day.
Microplastics and heavy metal contamination along a land-use gradient in a Himalayan foothill river: Prevalence and controlling factors
Researchers mapped microplastic and heavy metal contamination in a river flowing through India's Himalayan foothills, finding plastic particles at every sampling site. Concentrations were highest near industrial areas and human settlements, with polyethylene and polystyrene being the most common plastic types. The study shows how human activity drives plastic pollution even in relatively remote freshwater environments.
Spatial distribution of meso and microplastics in the sediments of river Ganga at eastern India
Meso- and microplastics were documented throughout the sediments of the Ganga River at sites in eastern India, with concentrations varying by location and sediment type. The study highlights that India's most sacred and heavily populated river carries significant plastic pollution that settles in sediments along its lower reaches.

This review examines microplastic pollution in India's Ganga River, which sustains hundreds of millions of people, identifying sources from industrial discharge, agricultural runoff, and inadequate waste management. Microplastics in the river threaten aquatic life through ingestion and bioaccumulation and ultimately affect the communities that rely on the river for drinking water and food. The study calls for comprehensive management strategies to protect both ecological and public health.
