Abstract: Plastic litter was quantified on four sandy beaches in Mumbai. 
The mean abundance of 7.49 g and 68.83 items per square metre was 
recorded. The abundance of plastics significantly varied among the 
beaches showing an increasing trend in the southern part. The abundance 
of plastics by weight in Dadar was significantly higher than that in 
Aksa. The size fractionation of plastics proved that small particles 
(1–20 mm) are predominant with 41.85% microplastics (1–5 mm) which 
emphasizes the high risk to marine organisms due to possible ingestion. 
The highest quantity of microplastics was seen in Juhu beach (55.33%) 
followed by Versova, Aksa and Dadar. The major contributing factors for 
the abundance are beach usage for different activities such as 
recreational, religious and fishing which suggest that the land-based 
sources provide major inputs to plastic pollution in these beaches.
