Abstract

In this study, the concentration, type and color of Micro Plastics (MPs) in the sediment profile of multiple inland water bodies across Ranchi was investigated. The totals of 4260 micro plastic particles in 400 gram sample taken from the different points were noted. The Concentration of MPs in the sediment of three different water bodies was about 100 to 150 particles per m2. Standard operation protocols set by National Oceanic and Atmospheric Administration (NOAA) were employed to carry out the experiment. Fibers were the predominant type of MPs in the sediment profile. The most common size was of 2 to 3 mm in the sediment. The dominant color of detected MPs in sediment was red, black and blue. Rayon, polyethylene and polyester were the major polymer types of selected particles. Kanke Dam showed most contamination as compared to Rukka Dam and Hatia Dam. This information may ease in adding our knowledge regarding Micro plastic pollution in inland freshwater ecosystem and provides a future monitoring and assessment of MPs in the inland aquatic system of Ranchi.
