Municipal solid waste landfills: a significant source of antibiotics and antibiotic resistance genes (ARGs)
The prevalence of antibiotic-resistant bacteria (ARB) and antibiotic-resistant genes (ARGs), driven by antibiotic use, represents a significant public health threat. The disposal practices for unused and unwanted antibiotics vary across regions and countries; however, a substantial portion of these antibiotics is often discarded in landfills alongside municipal solid waste (MSW). As a result, landfills become a major reservoir of antibiotics and ARGs. These contaminants can leach from landfills into the environment via landfill leachates, gas emission and refuse evacuation thereby posing risks to both human health and ecosystems. Consequently, understanding the environmental behavior of antibiotics and ARGs in landfills is crucial for effective resistome management and the protection of public health.
