AB  - The global presence and prevalence of microplastic have moved microplastic from 
      an emerging pollutant to a persistent contaminant. Microplastic prevails in 
      almost all spheres of the environment viz. terrestrial, marine and atmosphere the 
      globe abundantly. The prevalence and toxic effects on marine organisms have been 
      studied around the world but the studies are limited to the coastal regime of the 
      Andaman and Nicobar Islands (ANI). This study aims to record microplastic 
      prevalence on the tourist beaches of Port Blair, ANI. Three coastal stations 
      namely Cove beach, Quarry beach and Wandoor beach were examined in detail in this 
      regard. Microplastics in the form of lines, fragments, pellets, foams and fibres 
      were found at the sampled sites. Wandoor beach recorded the highest microplastic 
      particles ranging from 105-475 particles kg(-1) of sediment with the mean value 
      of 249.82 +/- 105.78 particles kg(-1). Quarry beach near the municipal waste 
      dumpsite showed the lowest of 72.5-222.5 particles kg(-1) with a mean value of 
      135.625 +/- 62.83 particles kg(-1). The polymeric forms found were High-density 
      polyethylene (HDPE), polystyrene (PS), polypropylene (PP) and polyethylene 
      terephthalate (PET). This study revealed microplastic input from municipal dump 
      waste near the beach. Fourier Transform Infrared spectroscopy (FTIR) revealed the 
      presence of a new type of polymer namely plasta zinc in the beach sediment, which 
      possibly could be a nanoplastic. Its presence reveals the biological enzymatic 
      degradation of microplastic occurring in the marine environment. Further 
      investigations are required to determine the factors influencing the prevalence 
      of microplastic, its toxic effects on marine habitat and microplastic degradation 
      mechanisms in the marine habitat.
