Adaptation of a method of the granulometric analysis for studying of microplastic pollution of deposits of a coastal zone of the sea

A new approach to the assessment of microplastic pollution of beach and bottom sediments of the coastal zone of the sea based on the study of their particle size distribution is proposed. A standard procedure for carrying out a complete granulometric analysis of the sediments in laboratory conditions is described. It uses the sieve method with and without washing with water adapted to the condition of their possible contamination with microplastics. Currently, this method is receiving practical approval during which the methods of processing beach and bottom sediments will be worked out and improved.
