To mitigate the presence of tetracyclines in water, it is essential to implement proper wastewater treatment processes that can effectively remove these compounds. In this work we develop a polymeric filtration membrane functionalized with nanocrystals metallic organic framework, designated by HKUST-1. The was evaluated for remotion oxytetracycline (OTC), tetracycline (TC), and chlortetracycline (CTC) water samples. fabricated using polysulfone (PSU), polyethyleneglycol (PEG), MOF (HKUST-1), N-methyl-2-pyrrolidone (NMP) through nonsolvent induced phase separation (NIPS) method. presents best antibiotic rejection characteristics prepared 15% (w/w) PSU, 3% PEG, 1% HKUST-1, 81% (NMP). This exhibited pure flux up 76.2 L.m-2.h-1, approximately 40 times more than one achieved pristine membranes. Once determined composition, physical-chemical characterization done. A high rate obtained OTC, TC, CTC, around 91%, 99% respectively. pH solutions has strong influence on rejection. results suggest intermolecular forces such as π-π type interactions hydrogen bonds exist between neutral molecules (pH>pKa1 pKa2. Furthermore, FTIR spectra demonstrate formation Cu-tetracycline complex another adsorption mechanism. Finally, interaction mixture removal performance evaluated. study revealed superior performance, even over extended periods time, despite having lower initial concentration mixture. innovative represents new generation highly efficient filter systems specifically designed purification purposes.

Antimicrobial resistance (AMR) is one of the biggest threats to environment and health. AMR rapidly invalidates conventional antibiotics, antimicrobial nanomaterials have been increasingly explored as alternatives. Interestingly, several show AMR-independent effects without detectable new therefore suggested prevent evolution. In contrast, some are found trigger evolution AMR. Given these seemingly conflicting findings, a timely discussion two faces urgently needed. This review systematically compares killing mechanisms structure-activity relationships antibiotics nanomaterials. We then focus on nano-microbe interactions elucidate impacts molecular initiating events Finally, we provide an outlook future propose design principles for prevention

The negative effect of the pharmaceuticals presence (persistence?) in various components environment is a global problem today. These compounds are released into as result of, inter alia, their use and improper disposal. Therefore, it important to reduce excessive drug consumption develop system for collection unused/expired pharmaceuticals. effectiveness actions this area inextricably linked with need educate society on how deal properly unwanted medications. aim study was show that inappropriate handling drugs by an waste management systems, impacts state environment. Forty-eight scientific articles published between 2012 2021 were taken account discussed systems countries This literature review shows main method disposing medications, according respondents from different countries, either them household or flushing sewage system. also case programs return redundant drugs, which indicates these not sufficiently effective. may be influenced many factors, including lack ineffective education society.
