Abstract

 

Aim: This study was conducted to identify and characterize microplastics in Yele Mallappa Shetty (YMS) Lake, Bengaluru.

Methodology: Water samples were collected from four distinct entry locations to the lake and analysed for microplastic as per the methods adopted by the National Oceanic and Atmospheric Administration (NOAA).

Results: Samples of three different microplastic foams—polyester, polyurethane, and polypropylene—were analysed using scanning electron microscopy (SEM), visual analysis, hot needle testing and Raman spectroscopy. The diameters of various components ranged from 0.2-3 mm, with the majority of the samples consisting of fibres (26%), fragments (27%), films (25%) and foam (22%). The mean concentration of microplastic recorded in the water sample was 10±0.7 particles l-1.

Interpretation: Protecting wetland ecosystems is essential because they provide countless services, such as food and building materials, biodiversity, flood control, and groundwater recharge. This study provideds valuable baseline data on microplastics in YMS lake for the first time.

Key words: Bengaluru lake; Lake water, Microplastic pollution, Water pollution, Yele Mallappa Shetty Lake
