In a recent global study, which surveyed the marine pollution across the world, it has been revealed that sea near Mumbai is the most polluted region with 68.83 waste items per sq meter. This region includes four beaches of Mumbai; Juhu, Dadar, Versova and Aksa.
This research has been carried out by Alfred Wegener Institute (AWI), Helmholtz Centre for Polar and Marine Research in Germany. The results have been derived from a comprehensive study of 1237 scientific studies, which has been integrated In Litterbase, a database on marine pollution research.
Mumbai sea water is being victimized since decades with recreational and religious activities taking place that lead to pollution in a large proportions along with the existing pollution through waste, contaminated, untreated water’s flow to the ocean. These activities have accumulated waste to such an extent that the beaches now have risen to threshold limits which not only affect the marine bio-diversity, but also puts threat to the health of the humans living around.
Microplastics have been found in ample in the sea-water near Mumbai, which registered 41 per cent of the total debris, size ranging from 1 mm to 5 mm. Juhu beach, the most popular in tourist attraction was found to have the highest amount of micro-plastic waste i.e. 55.33 per cent, whereas other beaches Versova, Dadar and Aksa were found to have 28.8 per cent, 18.6 per cent and 7.9 per cent respectively.
The AWI Litterbase data is the result of comprehensive analysis of the marine organisms that are severely affected by the polluted water, and the study has been compiled in the map format. This study reveals that the total of 1220 species is rigorously being affected and the number is only going to rise. The map covers polluted water of the coastal areas in India, Australia, Japan, Indonesia, Malaysia, China, South Africa, the US, European nations and few more.
