Design of equipment for observing the distribution of plastic waste in surf zones
Summary
This paper describes technical approaches for designing equipment to monitor the distribution of plastic debris in surf zones and on beaches. The authors propose improved sampling tools and traps for both large plastic and microplastic particles in the high-energy surf environment.
The publication highlights some technical issues related to the design of equipment for monitoring the distribution of plastic waste on sea beaches, in particular within the surf zones. Sample selection procedures, alternative to the existing ones, were considered, and certain methods and technical means were proposed to optimize the sampling process. The expediency of creating traps for macro- and microplastics, the long-term continuous use of which can open new methodological approaches to regular observations of these pollutants, is substantiated. Such field observations combined with the recording of hydrometeorological data (winds, currents, and dynamics of wave activity) will allow to determine the intensity of the introduction of plastic material from certain geographical locations and to investigate probable sources of input depending on the characteristics of its composition.
