[Environmental Pollution and Extraction Methods of Extracellular Antibiotic Resistance Genes in Water].

Antibiotics are widely used to treat diseases such as bacterial infections. However, the abuse of antibiotics has led to the spread of antibiotic resistant bacteria and intracellular and extracellular antibiotic resistance genes, making China one of the countries with the highest incidence of antibiotic resistance and thus threatening public health. Extracellular antibiotic resistance genes, as one of the novel environmental pollutants, could exist in water for a long time and could be transmitted between different bacteria through horizontal gene transfer, resulting in the spread of antibiotic resistance.

Catalytic detoxification of mitoxantrone by graphitic carbon nitride (g-CN) supported Fe/Pd bimetallic nanoparticles.

The overuse of antibiotics and antitumor drugs has resulted in more and more extensive pollution of water bodies with organic drugs, causing detrimental ecological effects, which have attracted attention towards effective and sustainable methods for antibiotics and antitumor drug degradation. Here, the hybrid nanomaterial (g-CN@Fe/Pd) was synthesized and used to remove a kind of both an antibiotic and antitumor drug named mitoxantrone (MTX) with 92.0% removal efficiency, and the MTX removal capacity is 450 mg/g.
