Microplastics in drinking water: A neglected public health risk in tropical settings
Abstract
The presence of microplastics in drinking water has gained recognition as an overlooked environmental and public health issue, especially in tropical regions characterized by rapid urbanization, improper waste management practices, and lack of adequate water treatment facilities. Microplastics refer to plastic fragments <5 mm in size and have been found in bottled water, tap water, and even groundwater. While the adverse health impacts of microplastics are yet to be fully established, scientific literature indicates potential links to oxidative stress, inflammation, hormonal imbalance, and gastrointestinal dysfunction. Tropical nations may also experience additional risks due to insufficient waste management and increased usage of plastics. This article discusses the possible health consequences related to microplastics in drinking water and underscores the importance of efficient waste disposal, appropriate water purification technologies, enhanced public education, and future research on this issue.
