Microplastics in aquatic environments: detection, abundance, characteristics, and toxicological studies.

Microplastics (MPs) are fragments with a diameter of less than 5 mm that have been directly manufactured or formed by the degradation of plastic waste. MPs are not only prone to bioaccumulation in the environment, but they also lead to the spread of micropollutants in the environment, thereby threatening human health ecological environment. The useful detection method of MPs and understanding their abundance, characteristics and toxicity are great essential for MPs removal and control.

Enhancement of Fenton processes at initial circumneutral pH for the degradation of norfloxacin with Fe@FeS core-shell nanowires.

The disadvantages of narrow working pH range (2.5-4.0), accumulation of iron sludge and incomplete degradation have hindered the practical application of the traditional homogeneous Fenton technique.
