| Abstract | The mismanaged plastic wastes leak into the environment, along with microplastics (MPs) created by purpose or by degradation by the environmental factors, find certain pathway by which its extent of dispersal on the natural environment in land, water and atmosphere is global. The Marine environment being the ultimate sink for all the unmanaged and leaked plastic wastes from land sources via rivers and direct dumping, bears a high load of mismanaged plastics as marine plastic debris or ocean plastics. Hence, it is very important to know the extent of pollution at various places in the world, as this information can help to know, monitor, and track the pollution around the world. And most importantly know the effects of pollution on species and natural environments, and how increasing plastic pollution is causing more problems. Apart from effects on health of species, there are many socio-economic factors affected by plastic pollution such as tourism, fisheries, and aquaculture. When extent of the pollution is studied and effects to biodiversity and ecosystems are seen, this information would then be used to find solutions to mitigate these problems, and will also push governments, INGOs and private sector to act, and results in global and national policies to tackle these problems to take place. In this study, MPs abundance in drainage areas in the beach is found to be more than double than in high tide line. Along with abundance of mesoplastics and MPs in beach high tide line, drainage area and surface water, characterization of MPs was also done based on type, color, and size. The study observed lower concentrations of MPs than previous studies around the same area, which necessarily means that loads of MPs and plastic debris are very dynamic and very hard to predict. It may even pose more danger to high productivity coastal ecosystems due to the observed unknown phenomena. However, it still needs to be studied how concentrations of MPs differ between various sampling techniques and sampling areas selected in the beach, how MPs varies over time with respect to external conditions, and how much risk does it pose to the ecosystems. |
