Multiple antibiotics used in the medicinal, livestock, and poultry breeding industries have detrimental effects on human and animal health, and have led to great concern in recent years
The Phragmites australis (PAS) was collected from the Yanghu Wetland, Hunan Province, China
The raw material was dried at 105◦C for 24 h, crushed into fractions with particle sizes of 0.15–0.25 mm, and stored in a sealed bag at 4◦C
Summary
Multiple antibiotics used in the medicinal, livestock, and poultry breeding industries have detrimental effects on human and animal health, and have led to great concern in recent years. Most antibiotics are excreted into the natural environment as prototypes or metabolites, resulting in environmental pollution. The primary sources of antibiotics in the water environment include sewage treatment plant wastewater, chemical manufacturing wastewater, animal husbandry, and aquaculture. Tetracycline (TC), one of the most widely used antibiotic, is widespread and frequently detected in the water environment. TC is easy to remain in water environment for a long time and cause environmental harm, mainly manifested in its adverse effects on nontarget organisms. Long-term exposure of organisms to the antibiotic environment will produce chronic toxicity, which can cause negative effects on terrestrial and aquatic ecosystems, and damage the balance of the ecosystem. The highly soluble TC is transferred to other environmental media via the water environment and must be removed in a technically, environmentally, and economically acceptable manner
