dc.description.abstract
Microplastics, a growing environmental concern, may pose a new threat to groundwater quality. These tiny plastic fragments can act as "hitchhikers" for harmful viruses, increasing their transport distances and persistence in the environment. Human enteric viruses, commonly found in wastewater and sewage sludge (often applied to agricultural soils), can attach to microplastic surfaces and create a combined new threat. These newly formed microplastic-virus aggregates could travel deeper into the soil and contaminate groundwater, potentially leading to disease outbreaks. While the exact mechanisms behind this "hitchhiking" are still unclear, our research aims to investigate the possibility of microplastics facilitating the transport of human enteric viruses in groundwater environments.
Flow-through experiments were conducted in 30 cm columns of quartz sand at a Darcy velocity of 2.65 m/day. The experiments considered three different injection solution scenarios: PRD1 mixed with microplastics, PRD1 alone and microplastics alone. The enumeration of PRD1 in the effluent solution was performed using quantitative polymerase chain reaction (qPCR) and the culture method to differentiate between total and infective virus transport.
Our findings indicate that surface charge may facilitate PRD1 attachment to microplastics. Following their attachment, the survival rate of infectious PRD1 was reduced (2-4 log10) between temperatures 4°C to 30°C after ten days. Overall, microplastics enhanced the transport of PRD1 (both total and infectious) through quartz sand. Interestingly, PRD1 had no impact on the transport behavior of the microplastics. Unlike the scenarios involving microplastics, PRD1 exhibited high attachment to quartz sand when transported alone, leading to more virus removal. Therefore, microplastics may act as carriers for viruses; understanding their transport mechanism is imperative to safeguard public health.
