The intertwining between the life cycle of plants and their pathogens made the plant circadian clock an integral constituent of the plant immune system. Reciprocally, pathogens were also found to perturb the expression pattern of certain clock genes. However, how pathogens influence clock components remains largely unknown.

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.

In recent years, copper-based nanomaterials (Cu-based NMs) have shown great potential in promoting agriculture development due to their special physicochemical characteristics. With the mass production and overuse of Cu-based NMs, there are potential effects on the soil-plant environment. Soil organisms, especially soil microorganisms, play a significant part in terrestrial or soil ecosystems; plants, as indirect organisms with soil-related Cu-based NMs, may affect human health through plant agricultural products.

Electro-Fenton (EF) can in-situ produce HO and effectively activate HO to generate powerful reactive species for the destruction of contaminants under acidic conditions, however, the production of iron-containing sludge and requirement of low working pH significantly hinder its practical application. Herein, a novel Cu, N co-doped carbon (Cu-N@C) with metal organic framework (MOF) as a precursor was constructed and adopted for the elimination of pefloxacin (PEF) in the heterogeneous electro-Fenton (HEF) process. PEF could be almost completely removed within 1 h and total organic carbon (TOC) removal efficiency was 48.

Significant concerns on a global scale have been raised in response to the potential adverse impacts of emerging pollutants (EPs) on aquatic creatures. We have carefully reviewed relevant research over the past 10 years. The study focuses on five typical EPs: pharmaceuticals and personal care products (PPCPs), per- and polyfluoroalkyl substances (PFASs), drinking water disinfection byproducts (DBPs), brominated flame retardants (BFRs), and microplastics (MPs).
