Urban freshwater bodies—rivers, lakes, ponds, and streams—are vital lifelines for cities, supporting diverse ecosystems and providing essential services to people. However, they are increasingly threatened by a pervasive and often invisible pollutant: microplastics.

At Neftaly, we are investigating how microplastic contamination impacts freshwater biodiversity and what it means for the health of our urban ecosystems.

🔬 What Are Microplastics?

Microplastics are tiny plastic particles less than 5 millimeters in size, originating from:

• Breakdown of larger plastic debris
• Synthetic fibers shed from clothing
• Microbeads in personal care products
• Industrial and household runoff

Due to their small size, microplastics easily enter waterways and persist in the environment, accumulating in sediments and water columns.

🐟 Impacts on Urban Freshwater Biodiversity

Microplastics pose several threats to aquatic life:

🦐 Ingestion and Toxicity

• Aquatic organisms, from tiny zooplankton to fish, often mistake microplastics for food, leading to physical harm, reduced feeding, and exposure to toxic chemicals attached to plastics.

🌿 Habitat Degradation

• Microplastic accumulation alters sediment quality and water chemistry, negatively affecting benthic (bottom-dwelling) organisms crucial for nutrient cycling.

🐦 Food Web Disruption

• Bioaccumulation of microplastics in aquatic species can affect predators, including birds and mammals, disrupting entire freshwater food webs.

📊 Neftaly’s Findings in Urban Waterways

Our ongoing monitoring in multiple cities reveals:

• High concentrations of microplastics in sediments near urban runoff points
• Detection of microplastics in guts of key indicator species such as freshwater insects and small fish
• Correlation between microplastic pollution and declines in sensitive species diversity

These findings underscore the urgency of addressing microplastic pollution to safeguard urban freshwater biodiversity.

🛠️ Neftaly’s Approach to Mitigation

To combat microplastic pollution, Neftaly advocates for:

• Improved urban waste management and reduction of plastic use at source
• Implementation of green infrastructure like bioswales and retention ponds to filter runoff
• Public education campaigns to reduce litter and promote responsible disposal
• Supporting research on biodegradable alternatives and plastic capture technologies

🌍 How You Can Help Protect Urban Freshwaters

• Reduce single-use plastics and opt for sustainable alternatives
• Support local clean-up efforts of rivers, lakes, and streams
• Spread awareness about microplastic pollution and its ecological impacts
• Advocate for stronger regulations on plastic waste management in your community
