A Pilot Study on Detection of Microplastics for Environmental Monitoring Using Inland Lakes as Ecological Indicators
The waterbodies of a city play a major role in its biodiversity and ecological well-being. The main aspect of this study was to select lakes close to urban areas that are affected due to garbage dumping or have wastewater treatment plants inlets in them and check for microplastics (MPs) presence in them. Seetharampalya and Puttenahalli lakes in Bangalore both showed the presence of microplastics in their water and bank sediment soil samples, which were segregated by the wet peroxide oxidation process. In scanning electron microscopy (SEM) analysis, the microplastics segregated from the water of Seetharampalya lake were found to be clumped and in clusters of uneven form and shape. Microplastics extracted from the soil of Seetharampalya lake were found to have sheet, like structures with occasional dumps or clusters. The microplastics sorted out from Puttenahalli lake water were uneven and had roughly rectangular structures. The soil microplastics recovered from Puttenahalli lake were found to be sheaths of globular masses. The energy dispersive spectroscopy (EDS) analysis majorly showed presence of carbon and oxygen. In Fourier transform infrared spectroscopy (FTIR) analysis, characteristic peaks at 719/cm and 1469/cm were observed. Similarly, in x-ray diffraction (XRD), the 26 values around 20 could be seen in all four samples. This is the first reported study of microplastics in these lakes of Bangalore. 2024 - Kalpana Corporation. -
A comprehensive review of microplastic pollution in freshwater and marine environments
Water popularly termed the The Elixir of Life is now polluted beyond control in several regions. Microplastics, the tiny contaminants have found their way into all walks of life. They have also been found to be present in human blood, multiple organs, and even breast milk. There is an abundance of microplastics in the air we breathe, the food we eat, and the water we drink. Curbing them has to start with a ban of all forms of primary microplastics, and single use plastics with preference being given to biodegradable alternatives. India in particular banned single use plastics in 2022, which put an end to several commonly used plastic items being replaced with biodegradables. Paint is one of the largest contributors to microplastics, followed by textile industry, cosmetic, pharmaceutical industry, packaging industry are all top contributors to microplastics. The wastewater treatment plants aren't designed to filter microplastics from the source and this results in microplastics polluting all water resources. Though several novel techniques for microplastic segregation exist such as sieving, filtration, density separation, visual sorting, alkali digestion exist, they aren't fully employed as the initial process of microplastic segregation from waste is still in question. 2024 The Author(s) -
Detrimental effects of microplastics in aquatic fauna on marine and freshwater environments A comprehensive review
The world is ever evolving and new technologies are popping up everywhere. New inventions and discoveries have created a better world, but not a sustainable one. The whole earth is drowning in various pollutants and garbage. Plastic pollution has garnered sufficient attention and there are various teams and organizations working toward cleaning our beaches, parks, and environment. However, all these actions will not suffice as plastics have trickled down into microplastics, which are posing a greater threat to our water systems and aquatic fauna. Several ongoing researches focus on marine microplastics, while only 13% of studies are on freshwater. Research on microplastics is now on the rise, with new strategies and restrictions being put into place to curb its accumulation in our marine and freshwater environments.

Exploring Microplastic Pollution in Bellandur and Madiwala Lakes of Bangalore: A Preliminary Study
Abstract: Microplastics are plastic debris/fragments measuring less than 5 mm, either produced as such or obtained due to the weathering and fragmentation of bigger plastics. They are an emerging pollutant that have already caused great havoc on aquatic organisms and are a major environmental concern. Microplastics are also found in the human body, but the extent of their harmful effects is not yet fully understood. The sources of microplastic entry into humans include food, water, and air. This study assesses the microplastic occurrence in water and bank sediment of Bellandur (L1) and Madiwala (L2) lakes in Bangalore. The lakes are surrounded by urban areas and are affected by sewage inlet, waste dumping, and commercial boating. The microplastics in the bank sediment and water samples were segregated using the Wet Peroxide Oxidation process. There were no visible microplastics obtainable from the water samples of both lakes. However, microplastics were segregated from the bank sediment of both lakes. The scanning electron micrographs of the microplastics segregated from the bank sediment of L1 were found to be like sheaths and in uneven form and shape. The microplastics retrieved from L2 bank sediment were uneven and sheaths of globular masses when observed using SEM. The EDAX analysis majorly showed the presence of carbon and oxygen in both samples. From the FTIR analysis, the microplastics derived from L1 bank sediment had characteristic peaks of Acrylonitrile Butadiene Styrene (ABS), and Polystyrene (PS). Whereas, the microplastics from L2 had unique peaks corresponding to both Polypropylene (PP), PS and ABS as identified by the absorption peaks pertaining to both CH3 bending (1366 cm1) and aromatic CH (2922 cm1) stretching vibrations. Similarly, in XRD, the 2? values around 20 could be seen in both samples. These peaks correspond to some form of crystallinity, but the microplastics may have degraded due to several factors in the environment leading to changes in their structural form. The SEM, EDAX, FTIR and XRD data confirm the presence of microplastics in both the samples. This is the first reported study of microplastics in these lakes of Bangalore and it implies the need to focus on mitigation strategies for retrieval of microplastics that continues to accumulate in these lakes.
