“…As with fibers, these microplastics are likely to originate from land-based human activity [12]. Plastic debris found in the sediments of Rameswaram Island, Gulf of Mannar, Indiaa densely populated coral island, also exhibited a dominance of white-colored and irregularshaped (other) plastic debris due to tourist activities and fishing [18].…”

The beach sediment samples from Kalim, Tri Trang, and Patong Beaches, Phuket Province, southern of Thailand were collected for preliminary investigation on coastal debris. A total of 9 samples were taken from a 1 x 1 m quadrat at the depth of 5 cm, parallel with the shore during the period of maximum low tides in November, 2018. Microplastics (particles size < 5 mm) were extracted using sodium chloride (1.15 g mL-1) and their characteristics- including abundance (items m-2), weight (g), density (itemsm-2), color and shape- were determined using a stereo microscope. The results showed that microplastic debris varied in abundance from 1 to 35 items m-2 at the three selected beaches, depending on sampling location. In comparison, abundance of macroplastic (> 2.5 cm) and mesoplastic debris (5 mm to 2.5 cm) varied from 1 item m-2 quadrat (Kalim Beach) to 38 items (Patong Beach), 9 items (Tri Trang Beach) and 68 items (Patong Beach) m-2. Blue fibers were predominant among microplastic debris found at Kalim Beach; these are likely to have originated from pieces of rope, safeguard lines and fishing materials. In contrast, microplastic debris found in Patong and Tri Trang Beaches were predominantly green in color. The results of this study provide an overview of the sources of microplastics in coastal environments, which provides a basis for developing long term plastic management plans for these highly popular beaches in Phuket Province.

“…For this reason, studies on the heavy metal contents in Indian rivers have been increasingly carried out in recent years [13]. However, there are hardly any studies on environmental MP concentrations in Indian watercourses to date [12,15], since the focus was on MP in marine environments [16][17][18][19][20]. It can be assumed that, on the one hand, the effluents discharged contain MP and that, on the other hand, solid waste degrades to MP once introduced into the environment and thus enters freshwater systems, too.…”

Microplastic particles are found in environmental compartments all over the world and receive a great deal of attention, especially in the aquatic environment. Currently, a particularly high input of microplastics via Asian rivers is assumed, but so far, there are hardly any data through field measurements. Three rivers in South India were considered for this purpose to focus on their microplastic load. The emphasis was on the comparison of microplastic concentrations in urban and rural rivers. While two rivers in the megacity Chennai (Tamil Nadu) were found to have an average microplastic concentration of 0.4 microplastic particles/L, a rural river near Munnar (Kerala) had an average concentration of 0.2 microplastic particles/L. Rough estimates of annual microplastic discharge from the Adyar River (Chennai) into the Bay of Bengal are found to be as high as 11.6 trillion microplastic particles. This study should be one of the first baseline studies for microplastic loads in South Indian streams and should be complemented with further environmental sampling before, during and after the monsoon season to get more detailed information on the storage and transportation of fluvial microplastics under different weather conditions.
