A study conducted by researchers from China Agricultural University and Wageningen University reveals that enhanced manure management practices in China have resulted in a 59% reduction in antibiotic pollution in rivers.
However, groundwater contamination has increased by 15% due to intensified manure application as organic fertilizer in agricultural fields.
Fluoroquinolones are the predominant antibiotics found in rivers, originating from pig, cattle, and chicken manure.
Sulfonamides are the main contaminants in groundwater, primarily from pig and sheep manure.
