Distribution and Characteristics of Microplastics in Indian Water Bodies: Present Understanding and Future Challenges
Summary
This review pulls together existing research on tiny plastic particles (microplastics) found in India's rivers and lakes, showing that fibers and fragments from common plastics like polypropylene and polyethylene are widespread contaminants. While the health effects on humans aren't fully known yet, these plastics can enter drinking water sources and the food chain, and the researchers point out that scientists still need standardized testing methods and more monitoring to truly understand the risks. The takeaway: microplastic pollution in freshwater is a growing concern, but much more research is needed before we can say exactly how it affects human health.
Microplastics (MPs), defined as plastic particles smaller than 5 mm, have become emerging environmental contaminants due to their adverse effects on aquatic ecosystems. In India, increasing plastic production coupled with inadequate recycling practices has significantly contributed to MP pollution, attracting growing scientific attention in recent years. This review presents a comprehensive assessment of MPs in Indian freshwater systems and examines their potential impacts on ecosystem services. Most existing studies have primarily concentrated on the occurrence and abundance of MPs, while limited information is available regarding their sources, transport mechanisms, environmental behaviour, and long-term ecological consequences. Current findings indicate that white-colored Fibres and fragments, mainly composed of polypropylene (PP), polyethylene terephthalate (PET), and polyethylene (PE), are the predominant MP types detected in Indian freshwater environments. Analytical techniques vary according to particle size, with larger MPs (>500 μm) commonly identified using attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), whereas smaller particles (<500 μm) are generally characterized through μ-FTIR imaging. However, inconsistencies in sampling strategies and analytical methodologies hinder reliable comparisons among studies. Therefore, future research should emphasise the development of standardized protocols, rigorous contamination control, long-term monitoring programs, advanced analytical methods, and expand ed investigations of freshwater ecosystems, particularly in central India, to enhance understanding and facilitate effective management of MP pollution.
