Aquatic plant reduces antibiotics in water and genetic damage in fish, Piracicaba River study shows
Why it matters: This study offers a natural solution to antibiotic pollution, protecting aquatic life and human health.
- Researchers at CENA-USP identified various antibiotic residues in the Piracicaba River, with concentrations peaking during the dry season due to reduced water volume.
- Chloramphenicol, an antibiotic prohibited in Brazilian livestock due to toxicity, was detected in lambari fish, posing a direct human health risk.
- The aquatic plant Salvinia auriculata demonstrated the ability to partially reduce antibiotic accumulation in the water, offering a promising phytoremediation strategy.
- Sediment in the river acts as a reservoir for antibiotics, with fluoroquinolones and sulfonamides found at levels higher than international comparable studies, indicating long-term contamination potential.
A groundbreaking study in Brazil reveals that the aquatic plant Salvinia auriculata significantly reduces antibiotic contamination in the Piracicaba River, mitigating genetic damage in fish. Researchers detected prohibited antibiotics like chloramphenicol in fish during dry seasons, highlighting a critical environmental and public health risk, while also offering a natural solution.
