Microplastics abundance in surface water and sediments along the Thoothukudi region, south Tamil Nadu, southeast India, during 2021-01-03 to 2021-12-08 (NCEI Accession 0282701)

This study estimated the monthly concentration of microplastics (i.e. plastics measuring less than 5mm) in surface water (reported in units of items/L) and sediments (reported in unit of items/kg d.w.) in six sampling sites along the Thoothukudi region, south Tamil Nadu, southeast India, during 2021-01-03 to 2021-12-08. Microplastics in the surface water were collected with a plankton net while those in the sediments were collected using a shovel. This dataset contains the results from all 72 surface water and 72 sediment samples, in a spreadsheet format.
