The fermentation is the main process to form the unique flavor and health benefits of dark tea. Numerous studies have indicated that the microorganisms play a significant part in the fermentation process of dark tea. Dark tea has the quality of "The unique flavor grows over time," but unscientific storage of dark tea might cause infestation of harmful microorganisms, thereby resulting in the remaining of fungi toxins. Mycotoxins are regarded as the main contributor to the quality of dark tea, and its potential mycotoxin risk has attracted people's attention. This study reviews common and potential mycotoxins in dark tea and discusses the possible types of masked mycotoxins in dark tea. A summary of the potential risks of mycotoxins and masked mycotoxins in dark tea is presented, intending to provide a reference for the prevention and risk assessment of harmful fungi in dark tea.

Besides classic illegal drugs, numerous designer drugs, also called new psychoactive substances (NPSs), are available on the global drug market. One of the biggest and fastest-growing substance classes comprises the synthetic cannabinoids. According to the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), 254 out of 950 monitored substances belong to this group of NPS, with 9 new cannabinoids registered for the first time in 2023.

A simple, tailor-made, novel chemosensor based on 1,10-phenanthroline Schiff base incorporating N, N-Diethylamino salicylaldehyde (1) was designed and synthesized. The sensing ability of chemosensor 1 was tested via colorimetric, UV-Vis and fluorescence spectroscopy. Chemosensor 1 could effectively and specifically detect diethylchlorophosphate (DCP) in acetonitrile displaying naked eye colour change from pale yellow to dark yellow while fluorogenic colour changes from blue to pink fluorescence (365 nm UV lamp irradiation).
