Phytoremediation
Rivers used to grow food crops and supply drinking water are quietly accumulating drugs and cosmetic chemicals — and understanding which plants can absorb and neutralize these pollutants is a low-cost, nature-based path to cleaner water for communities downstream.
The Yamuna River, a major water source for millions of people near Delhi, is loaded with chemicals from medicines and personal care products like shampoos and lotions. Scientists tracked eight of these chemicals through different seasons and watched how certain plants soaked them up from the water. This natural filtering ability — called phytoremediation — could be a cheap, green way to reduce pollution without expensive treatment plants.
Key Findings
Eight priority pharmaceutical and personal care product (PPCP) contaminants were detected and quantified in Yamuna River water, one of India's most critically polluted waterways.
Seasonal variation in contaminant loads was a key focus, suggesting pollution levels fluctuate significantly with time of year — likely worsened during low-flow dry seasons.
Plants showed measurable bioaccumulation of PPCPs from the water, indicating real potential — and also risk — of contaminants entering the food chain through aquatic vegetation.

Researchers studied how plants naturally filter out pharmaceutical drugs and personal care product chemicals from the heavily polluted Yamuna River near Delhi. They measured eight priority contaminants in the water and assessed how much these pollutants accumulate inside the plants, revealing the seasonal dynamics of this natural cleanup process.
Abstract Preview
In the critically polluted Yamuna River, a lifeline for the Delhi-NCR region, the interplay between seasonal contaminant loads and natural phytoremediation remains poorly understood. This study pre...
