Plastic pollution, both primary.and secondary. is an environmental challenge, prompting regulatory.actions at global and regional levels. With increasing research about the impacts of micro- and nanoplastics on ecosy.tems and human health, governments worldwide have undertaken efforts to address this issue. The global community.has advanced regulatory.efforts that have led to the implementation of national laws or regulations in numerous countries. These measures ban or restrict the use of primary.and secondary.microplastics and nanoplastics. An overview of global and European regulatory.frameworks is presented to provide context for the United States (US). In the endeavor to document plastics regulation development in the US, a description of regulatory.agencies and their roles in advancing policy.and rules as well as future direction and areas for improvement in regulating plastics are introduced. A discussion of what emerging regulations mean to utilities and industries is also provided along with a comparison of regulatory.frameworks.

In this article dedicated to the modeling of vertical mass transfers between the biofilm and the bulk flow, we have, in the first instance, presented the methodology.used, followed by.the presentation of various results obtained through analy.es conducted on velocity.fields, different fluxes, and overall transfer coefficients. Due to numerical constraints (resolution of relevant spatial scales), we have restricted the analy.is to low Schmidt numbers (Sc=0.1, Sc=1, and Sc=10) and a single roughness Rey.olds number (Re*=150). The analy.is of instantaneous concentration fields from various simulations revealed logarithmic concentration profiles above the canopy. In this zone, the concentration is relatively.homogeneous for longer times. The analy.is of results also showed that the contribution of molecular diffusion to the total flux depends on the Schmidt number. This contribution is negligible for Schmidt numbers Sc≥0.1, but nearly.balances the turbulent flux for Sc=0.1. In the canopy. the local Sherwood number, given by.the ratio of the total flux (within or above the canopy. to the molecular diffusion flux at the wall, also depends on the Schmidt number and varies significantly.between the canopy.and the region above. The exchange velocity. a purely.hy.rody.amic parameter, is independent of the Schmidt number and is on the order of 10% of in the present case. This study.also reveals that nutrient absorption by.organisms near the wall depends on the Schmidt number. Such absorption is facilitated by.lower Schmidt numbers.
