Dear Colleagues, Recently, one of the most contentious environmental issues has been the investigation of microplastics’ (MPs’) detrimental consequences in natural and water resources worldwide. In this regard, it is critical to, firstly, track the ways in which MPs are considered as key anthropocentric pollutants in terms of ecological risk and t...
