Health risks of drinking water contamination: Emerging Nanotechnology and green synthesized nanoparticles for chemical and microbial remediation
Abstract
Contamination of drinking water is a significant global public health issue, caused mainly by rapid industrialization, agricultural runoff, insufficient sanitary infrastructure, and unregulated waste disposal. A wide variety of pollutants, including heavy metals, pesticides, pharmaceutical residues, and microbiological agents, significantly contribute to disease loads, including acute diarrheal diseases and chronic systemic disorders such as cancer and neurological degeneration. Marginalized groups, especially in impoverished areas, are disproportionately impacted by hazardous water sources. Conventional treatment technologies have shown limited success but frequently fail to eliminate trace-level contaminants or tackle growing risks such as antibiotic-resistant bacteria and endocrine disruptors. Recent advancements in nanotechnology have transformational prospects for revolutionizing water quality management. Engineered nanomaterials, such as metal nanoparticles (NPs), carbon-based adsorbents, and metal-organic frameworks, have remarkable efficacy in eliminating heavy metals and microbiological agents owing to their distinctive physicochemical characteristics. Nanosensor-based detection systems provide real-time pollution monitoring at ultra-trace levels, improving surveillance and enabling swift reaction. This study synthesizes existing research about the health effects of drinking water contamination and emphasizes the burgeoning significance of nanotechnology in treatment and monitoring approaches. Confronting this complex dilemma necessitates a comprehensive strategy amalgamating cutting-edge technology, legislative reform, and community-driven solutions to guarantee equal access to potable water globally.
